The following is a medical media production from WRAMC-TV The periodontist service of the department of dentistry at walter reed Army Medical center presents reconstructive ginger herbal surgery. The free mucosal graft with Colonel Ronald L. Van Swole. Chief periodontist service walter reed. We now come to a most exciting phase of the reconstructive ginger bill surgery story that is the free ginger photographed or more correctly, the free new coastal graph. Now the advent of this procedure has really closed the circle for the clinician who is managing periodontal disease and specifically paradigm of disease where we have a ginger involvement. The procedure was first brought to life from the Paradigm Point of View at least by King and Panel in Philadelphia in 1964. However Dr. John Neighbours in the Journal of Gerontology in 1966 really focused our attention on this procedure and brought the clinician at large into thinking about this procedure in the management of these most difficult cases. Now when dealing with the free mucosal graph, we must remember that there are definite indications for its use. We must be aware of the fact that this this procedure should be used in cases where the width of attached from the free ginger ale margin to the mucus ginger ville junction is very narrow and generally this would involve one or more teeth and when I say more teeth we can do these up to four or five teeth in with or even more for that matter. It can be used in cases where there is a very shallow vestibule with high muscle attachments. In other words we can use it in cases where we have shallow vestibules to deepen the vestibule and it can be used in cases where we have friend um problems especially in the lower anterior region where along with this we have a thin zone of attached ginger or a complete lack of attached and many times we can use this in cases where a combination of these three indications are present. The main objectives of this procedure is to restore a zone of attached ginger which previously was lost and also in many cases to deepen the vestibule. The one big disadvantage of this procedure is that in most cases it cannot be used to cover denuded root surfaces. Uh If you remember however we do have other procedures to handle this problem. Dia grammatically. Let's go through the steps of this procedure especially in the preparation of the recipient bed. Now, pre operatively generally this case would present with a zone of minimal attached ginger bill or complete lack of attached ginger. But on one or more teeth along with us Many times we would have a positive friend um that is a friend um which attaches in the marginal tissue or in the propeller and is creating a movement in this marginal tissue in preparing the recipient bed. We like to start with with sharp tissue dissection at or slightly corona to the changeable junction. We carry this down into the vestibule via split thickness dissection. Being very careful that we leave connective tissue and perry Ostrom on the cortical plate. We want to be sure that this dissection is very smooth so that we do not create any areas where pooling of blood can occur. We carry this to the desired depth and to the desired width. We then secure the graph from either the palette or another. Any other area that we may have available, such as tissue removed in the course of ginger ectomy and carry this then to the previously prepared recipient bed and suture it into place as desired. Again being very careful that we immobilize this graph. One of the main principles to keep in mind is that we should place our futures and our surgical dressing in such a manner that we will secure complete immobilization of the graph during the initial three or four day healing phase. We then would cover our graft with a suitable paradigm dressing such as co pack and post healing. We should see a re development of a zone of attached ginger and repositioning of the previously involved at a much lower level. I'd like to demonstrate this procedure then on a case so that we get the steps down in mind before we go to our patient. This is a 55 year old male who is about to undergo complete prosthetic reconstruction. Prior to this though we felt that we must re establish a zone of attached on tooth number 20 through 22. In addition to this, we would like to deepen the vestibule slightly and reposition this presently positive friend um at a much lower level at this time. As you can see by the blanching on the label aspect of tooth number 21. We do have a positive friend. Um in this area there's also insertion of this friend um into the marginal tissue on the labial Aspect of Tooth # 22. After securing or achieving the desired anesthesia, we would prepare this area and for this particular case we have an excellent donor site that is the palette. Since this patient is essential. Ist in the maxillary arch we can choose either the right or left paddle area as the donor site. In this case we chose the left side. You can see the quality of the tissue which we have here which will make this procedure very nice. We now begin to prepare the recipient bed using the bard parker number 15 blade. Starting just coronal to the oval junction and we D. Epithelial guys at this level as you can see here keeping the blade parallel to the cortical plate. If we do this then we minimize the danger of penetrating the connective tissue and the Perrier. Now I carry this down about two millimeters with the bard parker and then I go to a instruments such as the Kirkland instrument again, keeping it parallel to the cortical plate and can continue to dissect down to the desired depth generally in this area we go down approximately 4 to 5 millimeters. And here we see it, the the recipient bed completely prepared and ready to receive the free mucosal graft again, keeping in mind that we want this very smooth to minimize pooling of blood between the connective tissue fibers. We want a very smooth bed when preparing the bed in the vicinity of the bicuspid. We must keep in mind that we have the mental frame and and the Contents of the mental framing in this area. And so we do not want to carry this much deeper than 4-5 mm. Or we may be impinging upon this very vital anatomical structure. So this must be kept in mind when preparing the bed in this particular area. Now, as we prepare to achieve the graph from the palette, the question comes to mind what type of instrument they are used to secure this. Now, initially back in the early 60 or in the sixties when the graph was first introduced, most clinicians, I think was using the again, number 15 Bard parker blade. In the ensuing years, various people came out with various types of graph knives. This happens to be one of the pack went knives with a strip of razor blade secured in the holder here and this is used by many people to advantage. I still prefer to use the number 15 Bard parker blade, Since I feel I can control the shape of my graft much better. We also know today that we would like to have our graft in the neighborhood of 1 to 1 and a quarter millimeters in thickness. And I can also use the bevel of the bard parker blade as a guide in in securing the proper thickness. Since this is approximately 1.5 millimeters, we can go through the initial incision or outlining incisions of the graft to just short of this bevel and we should then achieve the thickness that we desire. So we've gone to the palette in this case then and secure the graft. As you see here, this is the epithelial side. We have previously determined the shape and size that we desired. Either by using a paranormal probe and marking off the width and length in millimeters or by making a dry foil template placing it on the palate and then outlining the graft. Now this is the connective tissue side of the graph and this is a very important side and that we wish to have it very smooth, much like we wish to have the recipient bed very smooth. So that when the two connective tissues are placed together there will be no dead space for the pooling of blood. One thing to keep in mind when you remove this graft is that you stay orientated because it's very easy to mistake the epithelial side for the connective tissue side. And if we place the epithelium against the connective tissue, we will not get a take. And this is the donor site immediately after the graft was secured. Again. I would like to point out that this is a split thickness to section very thin a millimeter to a millimeter and a quarter inch thickness. And so bleeding is very, very minimal. And healing is very rapid here in this particular case will use the patient's full upper denture as a surgical stint to cover this area during the healing phase. We then carry the graph to the mouth and suture it in position as we see here. Now generally I'll place this suture first and it's in at an angle from the middle to the distal. We like to angle suture from the medial to the distal so that it is working in this direction. Well then uh place the anterior suture again in a slight uh distal to medial direction so that the graft is secured very tightly in this position. The last two sutures are placed right in the center of the propeller. And we might consider these as suspense or sutures to hold the graft at the desired height. The number that we place here would depend upon the length of your graph. If we were dealing with just a two tooth graph, then just one suspension of course would be necessary prior to placing our surgical surgical dressing, then I like to hold this craft in position for several minutes, four or five minutes with a gauze sponge soaked in normal sailing so that we get a fibrous adhesion between the two connective tissue surfaces. We then can go ahead and place the co pack that would use in this particular case. Now, previously we used to use a dry foil and place it between the graft and the sutures and the pack. Uh This was done to keep the sutures from becoming impregnated in the pack. However, in recent years I've stopped doing this since I found that this drive oil also interfered with retention of the pack and thereby stabilization of the graft, which is very very important. We now find that if we remove our pack very, very carefully starting in this area and peeling it back. If by chance, one suture does become impregnated in this pack, we can slip the suture scissors between the pack and the the tooth and cut the suture and then continue to remove the pack. In most cases, however, we find that the sutures do not become permanently impregnated in this pack, especially if you use silk and cut your ends very short. And this is the case one week. Post surgery and immediately post pack removal, you can see the tremendous amount of debris that has accumulated under the pack and most of this is necrotic epithelial cells which have collected here. Now we know from our wound healing studies of this particular procedure that the outer three layers at least of the epithelium do undergo necrosis and sloughing. And this is what we see here. We do see though beginning recapitalization of the graft in this particular area. We then would go ahead and remove the sutures. Clean up the area so that we have a surgical site which looks like this. If any of this necrotic tissue uh is still adhering to the graft. As we see here. We would leave it there because this will undergo normal stuff because of problems in plaque control for the patient. At this time I'd like to cover the area again for seven days. And this is the graph. Then at four weeks post surgery we can see the increased zone of attached ginger but which we have achieved and the fact that we have repositioned the friend um at a more typical level so that it no longer impinges upon this marginal tissue in these two teeth. And this is the palette. At four weeks healing is certainly complete here we see a little redness yet. And this will fade out in in another two or three weeks. So that at eight or nine weeks post surgery one would be hard put to be able to tell that a graft was secured from this area And then the appearance of the surgical site. At nine weeks post surgery, the graft is now mature epithelium is thick and quite normal. If we were to look at this histological again pointing out the wide zone of attached ginger which we have achieved in the area deepening of the vestibule repositioning of the friend. Um We can now refer the patient to the prostate honest and he can prepare his crowns and so forth. Feeling secure that the marginal tissue is stable here and will not undergo further recession. With that brief introduction, we can now go to our patient and take a look at the surgery that we are going to perform this morning. Her patient is a 17 year old um female as you can see who has undergone a great deal of dental therapy in the last several years. Specifically she's had full mouth orthodontic therapy and coupled with this or thematic surgery. Now back uh when the initial planning stages between the orthodontist and oral surgeon took place, it was noted that she had a minimal zone of attached ginger in the lower anterior region. For this reason the oral surgeon made Quota Chrome's of the area and we documented the area at that time. This was approximately 18 months ago. Now, in the ensuing months we noticed and the patient noticed also that the recession was continuing in this area. So let's take a look at this And here we can see on tooth number 20 for a recession area of approximately 1.5 millimeters. On tooth number 25 we see approximately two millimeters of recession with tangible involvement. Now we can show that more dramatically when we pick up our periodontal probe and close just a little bit kim. Thank you And pull this area and we see that we have an inadequate zone of attached ginger in this area and now we have a friend um which is coming into play uh what we might call again the positive friend. Um and if you see the movement the tip of the propeller between tooth number 24 and five I'll do that once more. So for this particular problem we chose the free mucosal graph to stabilize the zone of attached ginger and also to eliminate this positive friend um problem. Previous to going on camera here we have achieved anesthesia in the area. And so we'll go right into our surgery again, if you recall from our previous discussion, our first step is to d epithelial guys the remaining a minimal zone of attached ginger and then via split thickness to section create our recipient bed. Reach across the patient. This in this manner and we'll start the epithelial rising and we're going to extend the graft from About the midpoint and the pillow between tooth number 22 and 23 to the midpoint between tooth number 26 and 27. And generally I like to start the epithelial rising away from me and work towards me. Could you turn towards me just slightly? Excellent. Okay this is a time consuming phase of this procedure in that we want to be very sure that we in fact do d epithelial eyes if we are going to have a positive take from our grant. And so you can see as we the epithelium is following. So called blending in technique working right along here keep the blade of the instrument parallel to the cortical plate. If you do this then there's really no danger of penetrating the remaining connective tissue which is left behind. Or the perry Ostrum. Don't let the friend um become a problem. Just work right across it. And as you can see as we're working the freedom will fall away for us very nicely because we have detached the fibers of the freedom. Okay we've done half the area and I see that there is a small area of opportunity um still left intact. So we'll go back And work that one out. Okay well let's just continue our progress across and you can see the split thickness dissection that is developing here and then put the bard parker down and take another instrument. I like to use either the Goldman Fox or the Kirkland knife again keeping it parallel. And now very carefully extending the recipient bed to the desired depth. And we'll do that across the field. We must be very sure that no muscle fibers are going to still adhere to the bed below our graph. If this happens there'll be displacement of the graph and a lack of proper take here we see some of the epithelium still adhering in the depth of the vestibule. And we would like to trim that margin. Okay. And we will bring this down just a little more time. At this point I take a gauze sponge soaked in normal saline and we'll sponge this area off close just a little kim. And I think we can get a better a better view of the recipient bed. And we take a very close look at it now and make sure that there's no epithelium in any areas. So that then would be our recipient bed completed and ready to receive the graph. Now kim has an excellent donor site in that she has very healthy attached ginger on the lingual aspect of of our molars and first bicuspid and this will be the area that we're going to use. Now it's important that we achieve an adequate length in our graft. And so again we just take our probe, go to the lower and take a measurement or we can make a template out of dry foil, whichever is preferable. And then transpose this to the palette. Okay now we can see then that our graft is outlined very nicely. And then we can start from the distal aspect and again by a split thickness dissection, secure the graph. We try to keep these approximately 1 mm thickness. And again to reiterate, we can use the bevel on the bart parker as a guide And also you can see the instrument shining through the graph. And clinical experience will tell you when you're at the proxy, approximate thickness that you desire. I like to keep the under surface of the graft very smooth, just as we like to keep the recipient bed very smooth. So we worked this out very slowly. Keep the instrument parallel to the angle of the palette and this works out very nicely. A separated corn suturing forceps is excellent for this. You picked this up very lightly little pressure and we can complete the dissection. Okay, there we have the graft. This is the epithelial side and it's very important to stay orientated as to which is the epithelial side and which is the connective tissue side because they can look very similar. You see a very smooth under surface that we have achieved on this graph. And there we have it. This is the way I like to carry it to the oral cavity with one corner already on the needle close just just a little kim. Thank you. Now you can see the actual in homeostasis that we have maintained while working in another area. We'll start our future. Then in this area placing it into the zone of attached ginger which we left behind angling slightly toward the operator. And this first night I placed very loosely. Okay. And before removing that, that's just tap this in place. Very good. All right, okay. Could you take them out just a second. Now, after I get the graph tacked into place with the first suture. Then we like to again sailing soaked, sponge, position the graft through the whole field in the manner that we would like it to finally be. And hold it there slightly. And that looks like we've got the position that we would like. We'll bring it up just slightly. And now the next step is to place suture in the terminal or far side of the graft. And so here will be our last little suture. You might think of it as a suspense ary suture in the function that it performs after placing the sutures. I again take our normal saline soaked gauze and hold finger pressure on the graph for just a couple of seconds. And we can achieve some fibers adhesion of the graph to the underlying bed And there we have everything positioned properly at this point. Then we'll go ahead and put two little wire loops on the teeth for pack retention. Okay, well, we've placed the wire Loops now on the two lateral incisors as you can see here, which will aid us in the retention of the periodontal dressing, which we're now going to place all this time. Of course we were able to keep slight pressure on our graft and so we have a week to be sure. But we do have a fiber and adhesion between the graft and the underlying bed. Very carefully we would like to remove the gauze, making sure we do not displace the graft, checking it. And I placed the co pack over the wires that we have placed, being sure that it is incorporated around the the little loops. And then I worked the pack down a typically over the graft and this again helps in immobilization which is extremely important. And we can muscle trim as we see here. Right and there we have the surgical site completely dressed and we can feel quite confident that this pack will stay in place for the seven days that we wish it to. Especially since we have the wire loops. Now we'll place the same type of addressing on the palate. Let's just take a quick look there. We've again remember secured our graph via split thickness to section. Could you open real wide kim and tip your head up just a little bit and aspirated please. And you can see that we really have not had any trouble or any problem with undue hemorrhage. Since this was a very thin section as a matter of fact I think we can see that the blood clot has already formed over the donor site. Well now place co pack over this area in a similar manner as we did on the lower, give the patient postoperative instructions and dismiss her and we'll see her in seven days kim has now returned for the one week post operative treatment. And before we go into the oral cavity. I'd like to just say a few words about what we should look for today. Now specifically we're going to remove the uh surgical dressing and sutures. However, we also want to take a look at the healing up to this point. If you recall during the surgical phase, we were concerned with creating a very smooth recipient bed. Secondly, we were concerned with developing a thin graph from the palette generally in the range of 1 to 1.5 millimeters, which would give us a very thin lamb inappropriate. And thirdly we were concerned with stabilization of the graft. Now why were we concerned with this? Well, the big and critical question during the first three days of the healing phase is the revascularization of the graft initially from 1 to 2 or even three days. The graft is kept alive by what we call osmotic uh circulation or diffusion or plasma tick circulation. That is. Body fluids are bathing the graft and keeping it alive until the graft can become revascularization which takes place around three days and onward. Also we're concerned with the graph becoming organically fused with the underlying bed which begins to occur around the 6th or 7th day and continues on up into 20 or 24 days. So let's now go to the oral cavity and take a look at the graft site. You want to place that in at one week at one week. Post up kim tells me that you got along very well with the procedure? Uh The only problem she had was in eating and she had to watch her diet stay in softer foods and so forth. Well, what we're gonna do then today is very gently lift the surgical pack away from our retaining wires and here we can see one of the wires shining through. Go ahead and get us a a little sharper instrument. And I usually start at the closest surface to the operator and very gently pick this pack away. If the suture is incorporated in the surgical dressing, we can reach behind the pack and remove it so far. This has not occurred and were able to tease this off very nicely. Okay, no problem. Sutures are free of the pack and so then I can reach in and gently take this away. Now let's replace this and close just a little kim fine. There we go. Now we see that certainly there is some debris under the pack. And we normally do see this. Uh We also see some sloughing epithelial cells which are very free from the underlying graft which points out that epithelial ization in this particular case has occurred very well close just a little more if you would and we can reflect from both sides of our graft. So this is all re epithelial. Ized to this point. Let's go ahead and remove our sutures. Okay, keep that right in there. Very good. Just keep no problem. Okay, could you close again bit so we can get a closer look. So now the sutures have been removed and will now take a little cotton applicator and remove the discriminating epithelial cells. And there we have it. Now let's just comment a bit about the healing. Close a little bit more again, I want to emphasize that the graft is almost completely re epithelial ized here. So this would mean to me that we were fortunate in securing a very thin graft, creating a very smooth bed and getting uh excellent stabilization of our graft on that bed. And so then that we had a very rapid healing take place at this point. Now we'll go ahead and prepare some another mix of co pack and place it over the ground. Now, the only reason we're doing this is keep this in, the only reason we're gonna do this is that we would like to protect the surgical site for a few more days since the tissues would still be too tender for plaque control. Okay, well we've prepared another mix of our co pack and we'll re apply this to the surgical site again, incorporating it first into our retention loops. Once we have them over the pack over the loop, then we can work it down again over the surgical site. There we go. Let's just take the excess off. Okay. Okay, you can take this out now. We like to muscle trim this market down some more now. We haven't said anything about the donor site as yet. And so I would like to show you the healing that has occurred there. So the healing on the palate. And I think we can see that in my look in the little mirror and we see that that has re epithelial Ized and is no longer uh concern. As far as uh placing another surgical dressing over the area, the patient relates that there's just a slight amount of tenderness in the area and she can go ahead and start maintaining plaque control the area. Maybe kIM. If you could turn towards me a little bit and open a little wider we get another view of it. There we are completely rehab. A theory Ized. Okay again, thank you for coming in kim. And we'll see the patient again in approximately seven days to remove the retention wires, the surgical dressing and start her on her plaque control. We would like to now observe the 14 day post op healing phase of our free new coastal graph. Could you close your slightly kim? Thank you. If you recall, the objectives of the procedure was to establish a broader zone of attached ginger in the area of teeth number 24 and 25 were pre operatively. We had an inadequate zone of attached ginger with progressive recession. We can now see because we've used the blending in technique that our graft has fallen into place very, very nicely relative to the pre existing papillary attached tissue and the minimal zone of attached changer on the teeth in question. Our graft is at this point in time completely re epithelial. Ized although still quite immature. And another interesting observation is the fact that the previously involved friend um has been repositioned at a much lower level and it is being retained at this lower level by the presence of the free meal coastal graft. So in sum total then at this point in time we can go ahead and have the patient begin plaque control of the area. And we should be able to then observe the maturation of the surgical site. At this point, I like to have the patient go to one of our multi tufted, soft rounded bristle toothbrushes and begin to manage this area. In a roll technique brushing from the graft to the tooth in a very deliberate manner. Such as we can see here at a later time. We may adjust this relative to the results that the patient can achieve with this tooth brushing technique, We would now like to go to the palette And observe the 14 day healing phase. Here. Here again we can see the complete re epithelial ization of the grafted site or the donor site. Let's take a look at that again, get this position just right, okay. It's very very difficult to pick out the donor site as a matter of fact at this point in time since recapitalization is complete, there's a very slight red undertone to this tissue which will disappear in another week to 10 days as maturation continues in this area. We wish to now observe the six week post op period for the free mucosal graft which was accomplished in tooth number 23 to 25 area. Now, specifically at this period of time, we feel that the graph should be completely healed. That is re epithelial Ization has occurred and is now mature and that revascularization of the graft is also complete. As a matter of fact, previous wound healing studies have shown us that within 4-4 and a half weeks after accomplishing a Freeman coastal graft, the revascularization of the graph should be complete. We also would like to observe the graph relative to the goals that we uh set up for ourselves initially to see if they have now been fulfilled. Would you close just a little more? And I think observing the graph very closely, we can say that these goals have in fact been fulfilled. Number one. We have increased the zone or width of attached ginger from the free ginger margin to the depth here. Now of approximately 4 to 5 millimeters, we have established a very definite vestibular depth in this area so that the pull of the mentality muscle in this area is now dissipated down here. Which will I think stabilize the position of the free changeable margin in this area so that the patient no longer needs to be concerned with continued recession as was observed after her orthodontic therapy. In addition to that, I would like to point out that the graft is very stable, that it is it is completely unmovable in this area and then given uh reasonable degree of home care. And of course this patient's home care is excellent. We can predict that the graft will stay in this position as long as the patient needs it here. If we could zoom in on this now into my mirror and if I turn that you can see that there is no residual evidence of the donor site. And this is what we routinely see when accomplishing the free mucosal graph that is a recapitalization of the donor site is complete and certainly by six weeks evidence of grass being secured from the area is completely gone. I think then that is all we need to see say about this procedure. It's highly predictable one. And uh if certain principles that we discussed earlier are carried out, one can predict total success in this procedure. A medical media production from W R E M C T VV
