Tooth movement and implant esthetics. 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. With this access, the surgeon is able to make the third incision, which is also known as the interdental incision, to separate the collar of gingiva that is left around the tooth. The initial or the first incision is the internal bevel incision given not more than 1 mm from the crest of the gingiva and directed to the crest of the bone. The three different categories of flap techniques used in periodontal flap surgery are as follows: (1) the modified Widman flap; (2) the undisplaced flap; and (3) the apically displaced flap. This incision, together with the initial reverse bevel incision, forms a V-shaped wedge that ends at or near the crest of bone. Fugazzotto PA. 1. References are available in the hard-copy of the website. B. The first incision or the internal bevel incision is then made from the bleeding points directed at an apical level to the alveolar crest. Coronally displaced flap Connective tissue autograft Free gingival graft Laterally positioned flap Apically displaced flap 5. Contents available in the book . After this, partial elevation of the flap is done with the help of a small periosteal elevator. When the flap is placed apically, coronally or laterally to its original position. This procedure was aimed to provide maximum protection to osseous and transplant recipient sites. The flaps are then apically positioned to just cover the alveolar crest. Normal interincisal opening is approximately 35-45mm, with mild, Periobasics A Textbook of Periodontics and Implantology, Text Book of Basic Sciences for MDS Students, History of surgical periodontal pocket therapy and osseous resective surgeries. The full-thickness mucoperiosteal flap procedure is the same as that described for the buccal and lingual aspects. 1- initial internal bevel incision 2- crevicular incisions 3- initial elevation of the flap 4- vertical incisions extending beyond the mucogingival junction 5- SRP performed 6- flap is apically positioned 7- place periodontal dressing to ensure the flap remains apically displaced Contents available in the book . Full-thickness or partial thickness flap may be elevated depending on the objectives of the surgery. Preservation of good blood supply to the flap is another important consideration. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. This is especially important because, on the palatal aspect, osseous deformities such as heavy bone ledges and exostoses are commonly seen. 6. It is caused by trauma or spasm to the muscles of mastication. These techniques are described in detail in Chapter 59. 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. Although some details may be modified during the actual performance of the procedure, detailed planning allows for a better clinical result. Wood DL, Hoag PM, Donnenfeld OW, Rosenfeld LD. When the flap is returned and sutured in its original position. Contents available in the book .. Thus, an incision should not be made too close to the tooth, because it will not eliminate the pocket wall, and it may result in the re-creation of the soft-tissue pocket. This technique offers the possibility ol establishing an intimate postoperative adaptation ol healthy collagenous connective tissue to tooth surlaces " and provides access for adequate instrumentation ol the root surtaces and immediate closure ol the area the following is an outline of this technique: With the help of Ochsenbein chisels (no. In addition, the interdental incision is performed after the flap is elevated to remove the interdental tissue. Unsuitable for treatment of deep periodontal pockets. The researchers reported similar results for each of the three methods tested. The margins of the flap are then placed at the root bone junction. It is discarded after the crevicular (second) and interdental (third) incisions are performed (Figure 57-5). 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. It is also known as a partial-thickness flap. Unrealistic patient expectations or desires. Minor osteoplasty may be carried out if osseous irregulari-ties are observed. Local anesthesia is administered to achieve profound anes-thesia in the area to be operated. Alveolar crest reduction following full and partial thickness flaps. In this flap procedure, all the soft tissue, including the periosteum is reflected to expose the underlying bone. This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. A progressive brous enlargement of the gingiva is a facet of idiopathic brous hyperplasia of the gingiva (Carranza and Hogan,; Gorlinetal., ).Itisdescribedvariouslyas bromatosisgingivae,gingivostomatitis,hereditarygingival bromatosis, idiopathic bromatosis, familial elephantiasis, and di use broma . In Figure 2, the frequency of the types of flap surgical techniques followed were analyzed. The incision is made not only around the facial and lingual radicular area but also interdentally, where it connects the facial and lingual segments to free the gingiva completely around the tooth (Figure 57-9; see Figure 57-5). What are the steps involved in the Apically Displaced flap technique? 12 or no. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. 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 increase in the width of the attached gingiva is based on the apical shift of the mucogingival junction, which may include the apical displacement of the muscle attachments. The incision is carried around the entire tooth. Need to visually examine the area, to make a definite diagnosis. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. Expose the area for the performance of regenerative methods. The incision is made at the level of the pocket to discard the tissue coronal to the pocket if there is sufficient remaining attached gingiva. Contents available in the book .. The narrow width of attached gingiva which may further reduce post-operatively. The main advantages of this procedure are the preservation of maximum healthy tissue and minimum post-operative discomfort to the patient. Contents available in the book . Burkhardt R, Lang NP. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. The internal bevel incision is also known as reverse bevel incision because its bevel is in the reverse direction from that of the gingivectomy incision. 30 Q . The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. The aim of this study was to test the null hypothesis of no difference in the implant failure rates, postoperative infection, and marginal bone loss for patients being rehabilitated by dental implants being inserted by a flapless surgical procedure versus the open flap technique, against the alternative hypothesis of a difference. 4. 2. Then, it is decided that how much tissue has to be removed so that the appropriate thickness of the gingiva is achieved at the end of the procedure. The influence of tooth location on the outcomes of multiple adjacent gingival recessions treated with coronally advanced flap: A multicenter ReAnalysis study Article Jun 2019 Giovanni Zucchelli. Triangular The choice of which procedure to use depends on two important anatomic landmarks: the pocket depth and the location of the mucogingival junction. Contents available in the book .. Moreover, the palatal island flap is the only available flap that can provide keratinized mucosa for defect reconstruction. Contents available in the book .. drg. This is especially important in maxillary and mandibular anterior areas which have a prime esthetic concern. Contents available in the book .. The bone remains covered by a layer of connective tissue that includes the periosteum. They are also useful for treating moderate to deep periodontal pockets in the posterior regions. Flap design for a conventional or traditional flap technique. . Under no circumstances, the incision should be made in the middle of the papilla. The use of continuous suturing in suture materials tearing through the flap edges and both plastic surgery (1) and periodontal surgery subsequent retraction of the flaps to less desirable has many advantages. In other words, we can say that. It is indicated when the flap has to be positioned apically and when the exposure of the bone is not required. A Technique to Obtain Primary Intention Healing in Pocket Elimination Adjacent to an Edentulous Area Article Jan 1964 G. Kramer M. Schwarz View Mucogingival Surgery: The Apically Repositioned. The area is re-inspected for any remaining granulation tissue, tissue tags or deposits on the root surfaces. Step 2:The initial or internal bevel incision is made (Figure 59-4) after scalloping the bleeding marks on the gingiva (Figure 59-5). A periodontal flap is a section of gingiva and/or mucosa surgically separated from the underlying tissue to provide visibility and access to the bone and root surfaces 1. 5. Periodontal flaps can be classified as follows. Gain access for osseous resective surgery, if necessary, 4. Evian et al. With this incision, the gingiva containing pocket lining is separated from the tooth surface. The patient is then recalled for suture removal after one week. The horizontal or interdental incision is then made using a small knife (Orban 1 or 2), severing the supracrestal gingival fibers. For the undisplaced flap, the internal bevel incision is initiated at or near a point just coronal to where the bottom of the pocket is projected on the outer surface of the gingiva (see Figure 59-1). 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.
