The area is then irrigated with an antimicrobial solution. It is most commonly caused due to infection and sloughing of blood vessels. Position of the knife to perform the crevicular (second) incision. Periodontal flaps can be classified as follows. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. The internal bevel incision accomplishes three important objectives: (1) it removes the pocket lining; (2) it conserves the relatively uninvolved outer surface of the gingiva, which, if apically positioned, becomes attached gingiva; and (3) it produces a sharp, thin flap margin for adaptation to the bonetooth junction. This flap procedure causes the greatest probing depth reduction. The internal bevel incision may be a marginal incision (from the top of gingival margin) or para-marginal incision (at a distance from the gingival margin). a. The primary incision is placed at the outer margin of the gingivectomy incision starting at the disto-palatal line angle of the last molar and continued forward. The factors that are associated with post-operative swelling include the type of the incision, its extension, tissue manipulation during the surgery and the duration of surgery. The margins of the flap are then placed at the root bone junction. There are two types of incisions that can be used to include interdental papillae in the facial flap: One technique includes semilunar incisions which are. The bleeding is frequently associated with pain. Every effort is made to adapt the facial and lingual interproximal tissue adjacent to each other in such a way that no interproximal bone remains exposed at the time of suturing. Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. Step 4:After the flap is reflected, a third incision is made in the interdental spaces coronal to the bone with a curette or an interproximal knife, and the gingival collar is removed (Figure 59-3, E and F). Contents available in the book .. Flap adaptation is then done with the help of moistened gauze and any excess blood is expressed. a. Non-displaced flap. The process of healing progresses through various phases of . The area is then re-inspected for any remaining granulation tissue, tissue tags and deposits on root surfaces. Reconstruction of Distal Phalangeal Soft Tissue Defects with Reverse Homodigital Artery Island Flap, , 2014-11, () . Contents available in the book . When bone is stripped of its periosteum, a loss of marginal bone occurs, and this loss is prevented when the periosteum is left on the bone. Possibility of exposure of furcations and roots, which complicates postoperative supragingival plaque control. (Courtesy Dr. Silvia Oreamuno, San Jose, Costa Rica. The distance of the incision from the gingival margin (thickness of the incision) varies according to the pocket depth, the thickness of the gingiva, width of the attached gingiva, shape and contour of gingival margins and whether or not the operative area is in the esthetic zone. To perform this technique without creating a mucogingival problem it should be determined that enough attached gingiva will remain after after removal of pocket wall. This incision is placed through the gingival sulcus. It is caused by trauma or spasm to the muscles of mastication. In areas with deep periodontal pockets and bone defects. Severe hypersensitivity. The researchers reported similar results for each of the three methods tested. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. With this access, the surgeon is able to make the. The blade should be kept on the vertical height of the alveolus so that palatal artery is not injured. Journal of clinical periodontology. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. The main disadvantage of this procedure is that healing in the interdental areas takes place by secondary intention. 5. The conventional flap is used (1) when the interdental spaces are too narrow, thereby precluding the possibility of preserving the papilla, and (2) when the flap is to be displaced. . If the dressing has to be placed, a dry foil is first placed over the flap before covering it with the dressing so that the displacement of the pack under the flap is prevented. The horizontal incisions are used to separate the gingiva from the root surfaces of teeth. This incision, together will the para-marginal internal bevel incision, forms a V-shaped wedge ending at or near the crest of bone, containing most of the inflamed and, The base of the flap should be wider than the flap margin so that the blood supply to the flap is not jeopardized. Tooth with extremely unfavorable clinical crown/root ratio. The first incision or the internal bevel incision is then made from the bleeding points directed at an apical level to the alveolar crest. Contents available in the book .. The following steps outline the modified Widman flap technique. A. 2. See Page 1 Flaps are used for pocket therapy to accomplish the following: 1. 1. Frenectomy-frenal relocation-vestibuloplasty. The square . In a full-thickness flap, all of the soft tissue, including the periosteum, is reflected to expose the underlying bone. The primary incision or the internal bevel incision is then made with the help of No. Unsuitable for treatment of deep periodontal pockets. The modified Widman flap procedure involves placement of three incisions: the initial internal bevel/ reverse bevel incision (first incision), the sulcular/crevicular incision (second incision) and the horizontal/interdental incision (third incision). The necessary degree of access to the underlying bone and root surfaces and the final position of the flap must be considered when designing the flap. For the correction of bone morphology (osteoplasty, osseous resection). Contents available in the book .. We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. Contents available in the book . Short anatomic crowns in the anterior region. The entire surgical procedure should be planned in every detail before the procedure is initiated. The modified Widman flap facilitates instrumentation for root therapy. This is also known as. 1. It reduces mouth opening, is commonly associated with pain and causes difficulty in mastication. Conventional flap. B. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective . 7. ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. Clinical crown lengthening in multiple teeth. The meniscus comma sign has been described for displaced flap tears of the meniscus. It is caused by trauma or spasm to the muscles of mastication. 12 or no. Inferior alveolar nerve block C. PSA 14- A patient comes with . The patient is recalled after one week for suture removal. The blade is introduced into the sulcus or pocket and is inserted as far as possible into the interdental space around the tooth, keeping it close to the crown. After thorough debridement, the area is then inspected for any remaining deposits on the root surfaces, granulation tissue or tissue tags. Step 2:The gingiva is reflected with a periosteal elevator (Figure 59-3, D). The intrasulcular incision is given using No. The secondary incision is given from the depth of the periodontal pocket till the alveolar crest. This technique offers the possibility of establishing an intimate postoperative adaptation of healthy collagenous connective tissue to tooth surfaces,2,3,5,6 and it provides access for adequate instrumentation of the root surfaces and immediate closure of the area. Contents available in the book .. The following outline of this technique: These are indicated in cases where interdental spaces are too narrow and when the flap needs to be displaced. Following is the description of step by step procedure followed while doing a modified Widman flap surgery. Short anatomic crowns in the anterior region. To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. This incision is indicated in the following situations. Undisplaced (replaced) flap This type of periodontal flap Apically positions pocket wall and preserves keratinized gingiva by apically positioning Apically displaced (positioned) flap This type of incision is used for what type of flap? The most abundant cells during the initial healing phase are the neutrophils. It does not attempt to reduce the pocket depth, but it does eliminate the pocket lining. Give local anaesthetic for 2 weeks and recall C. Recall for follow up after 6 weeks D. 13- Which is the technique that will anesthetize both hard and soft tissues of the lower posterior teeth region in one injection A. Gow gates***** B. As described in, Image showing primay and secondary incisions used in ledge and wedge technique. This is termed. Suturing is then done using a continuous sling suture. One of the most common complication after periodontal flap surgery is post-operative bleeding. Areas where greater probing depth reduction is required. To fulfill these purposes, several flap techniques are available and in current use. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. Kirkland flap method was the most commonly followed (60.47%), then it was modified widman flap (29.65%), undisplaced flap (6.39%) and distal wedge which was the lowest (3.48%). This type of incision, starting just below the bleeding points, removes the pocket wall completely. 2. Although some details may be modified during the actual performance of the procedure, detailed planning allows for a better clinical result. Sutures are placed to secure the flaps in their position. The distance of the incision from the gingival margin (thickness of the incision) varies according to the pocket depth, the thickness of the gingiva, width of the attached gingiva, shape and contour of gingival margins and whether or not the operative area is in the esthetic zone. The undisplaced flap is therefore considered an internal bevel gingivectomy. Within the first few days, monocytes and macrophages start populating the area, Post-operative complications after periodontal flap surgery, Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. Contents available in the book .. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. When the flap is returned and sutured in its original position. In areas with shallow periodontal pocket depth. It is an access flap for the debridement of the root surfaces. The pockets are then measured and bleeding points are produced with the help of a periodontal probe on the outer surface of the gingiva, indicating the bottom of the pocket. The incision is made . Papillae are then sutured with interrupted or horizontal mattress sutures. At last periodontal dressing may be applied to cover the operated area. After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades, In this technique, two incisions are made with the help of no. Vertical relaxing incisions are usually not needed. Contents available in the book . During the initial phase of healing, inflammatory cells are attracted by platelet and complement derived mediators and aggregate around the blood clot.
