Internal bevel and is 0.5-1.0mm from gingival margin Modified Widman Flap This flap procedure causes the greatest probing depth reduction. 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: To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. The key point to be remembered here is, more the thickness of the gingiva more scalloped is the incision. When the flap is placed apically, coronally or laterally to its original position. May cause attachment loss due to surgery. 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 . - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap. The main causes for the bleeding include intrinsic trauma to the operated site, even after repeated instructions patients tend to play with the area of surgery with their tongue and dislodge the blood clot, tongue may also cause suction of blood by creating small negative pressures that cause secondary bleeding, presence of foreign bodies, infection, salivary enzymes may lyse the blood clot before it gets organized and slippage of suture. That portion of the gingiva left around the tooth contains the epithelium of the pocket lining and the adjacent granulomatous tissue. Therefore, the two anatomic landmarksthe pocket depth and the location of the mucogingival junctionmust be considered to evaluate the amount of attached gingiva that will remain after the surgery has been completed.

The periodontal pockets on the distal aspects of last molars, both in maxillary and the mandibular arches present a unique situation for which specific surgical designs have been advocated. In the present discussion, we discussed various flap procedures that are used to achieve these goals. The area is then re-inspected for any remaining granulation tissue, tissue tags and deposits on root surfaces. Areas where greater probing depth reduction is required. Minor osteoplasty may be carried out if osseous irregulari-ties are observed. Now, after the completion of the partial-thickness flap, the scalpel blade is directed from the base of this incision towards the bone to give a scoring incision.

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. Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap with or without resective osseous surgery, and orthodontic forced eruption with or without fibrotomy have been proposed for clinical crown lengthening. Our main aim of doing so is to get complete access to the root surfaces of the teeth and bone defects around the teeth. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. Undisplaced flap Palatal Flap The surgical approach is different here because of the nature of the palatal tissue which is attached, keratinized tissue and has no elastic properties associated with other gingival tissues, hence no displacement and no partial thickness flaps. Contents available in the book .. When the flap is returned and sutured in its original position. It is discarded after the crevicular (second) and interdental (third) incisions are performed (Figure 57-5). The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. Osce Handbook [34m7z5jr9e46] Tooth movement and implant esthetics. The following steps outline the undisplaced flap technique. TWO-LEVEL FRACTURES OFTHE TIBIA Results inThirty-six CasesTreated 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 soft tissue is then retracted with tissue forceps and the scoring incision is given to separate the periosteum from the bone. Short anatomic crowns in the anterior region. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. Diagram showing the location of two different areas where the internal bevel incision is made in an undisplaced flap. However, to do so, the attached gingiva must be totally separated from the underlying bone, thereby enabling the unattached portion of the gingiva to be movable. 2. For flap placement after surgery, flaps are classified as either (1) nondisplaced flaps, when the flap is returned and sutured in its original position, or (2) displaced flaps, which are placed apically, coronally, or laterally to their original position. 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. May cause esthetic problems due to root exposure. Gain access for osseous resective surgery, if necessary, 4. The starting point on the gingiva is determined by whether the flap is apically displaced or not displaced (Figure 57-7). Undisplaced flap, What is a periodontal flap? Dr Teeth - YouTube The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. Periodontal flap surgeries: current concepts - periobasics.com A Review of the Use of 3D Printing Technology in Treatment of Scaphoid This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. Flap for regenerative procedures. After the administration of local anesthesia, bone sounding is performed to identify the exact thickness of the gingiva. Following are the steps followed during this procedure. Swelling hinders routine working life of patient usually during the first 3 days after surgery 41. The following steps outline the undisplaced flap technique: Step 1: The pockets are measured with the periodontal probe. For regenerative procedures, such as bone grafting and guided tissue regeneration. 4. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. 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 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 incision is made on the buccal aspect of the tooth till the desired level, sparing the interdental gingiva. Contents available in the book .. Unsuitable for treatment of deep periodontal pockets. The area is then irrigated with an antimicrobial solution. The entire surgical procedure should be planned in every detail before the procedure is initiated. The antibiotics should be started before the surg-ical procedure so that appropriate antibiotic levels are there in blood at the time of surgery to prevent spread of infection. These landmarks establish the presence and width of the attached gingiva, which is the basis for the decision. Log In or, (Courtesy Dr. Kitetsu Shin, Saitama, Japan. It produces a sharp, thin flap margin for adaptation to the bone-tooth junction. If the incisions have been made correctly, the flap will be at the crest of the bone with the scalloped papillae positioned interproximally, thus permitting its primary closure. Local anesthesia is administered to achieve profound anes-thesia in the area to be operated. This complete exposure of and access to the underlying bone is indicated when resective osseous surgery is contemplated. Following is the description of step by step procedure followed while doing a modified Widman flap surgery. Periodontal maintenance (Supportive periodontal therapy), Orthodontic-periodontal interrelationship, Piezosurgery in periodontics and oral implantology. After one week, the sutures are removed and the area is irrigated with normal saline solution. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. The thickness of the gingiva. Connective tissue grafting harvesting techniques as well as free gingival graft. Flap adaptation is then done with the help of moistened gauze and any excess blood is expressed. 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). . The most abundant cells during the initial healing phase are the neutrophils. Contents available in the book .. It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. If the surgeon contemplates osseous surgery, the first incision should be placed in such a way to compensate for the removal of the bone tissue so that the flap can be placed at the toothbone junction. In the following discussion, we shall study in detail, the surgical techniques that are followed in various flap procedures. A periodontal flap is a section of gingiva, mucosa, or both that is surgically separated from the underlying tissues to provide for the visibility of and access to the bone and root surface. In a full-thickness flap, all of the soft tissue, including the periosteum, is reflected to expose the underlying bone. The presence of thin gingiva which does not allow placement of adequate initial internal bevel incision. Sixth day: (10 am-6pm); "Perio-restorative surgery" After the primary incision, tissue can now be retracted with the help of rat-tail pliers. This incision is made from the crest of the gingival margin till the crest of alveolar bone. The granulation tissue and the pocket lining may be then separated from the inner surface of the reflected flap with the help of surgical scissors and a scalpel. in adults. Unsuitable for treatment of deep periodontal pockets. Coronally displaced flap. In areas with deep periodontal pockets and bone defects. Contents available in the book .. The patients were assigned randomly to one of the techniques, and results were analyzed yearly for up to 7 years after therapy. Pocket depth was initially similar for all methods, but it was maintained at shallower levels with the Widman flap; the attachment level remained higher with the Widman flap. Figure 2:The graph represents the distribution of various This wedge of tissue contains most of the inflamed and granulomatous areas that constitute the lateral wall of the pocket as well as the junctional epithelium and the connective tissue fibers that still persist between the bottom of the pocket and the crest of the bone. 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 . One incision is now placed perpendicular to these parallel incisions at their distal end. In this technique, two incisions are made with the help of no. The interdental papilla is then freed from the underlying bone and is completely mobilized. The main advantages of this procedure are maximum conservation of the keratinized tissue, maximum closure of the flaps and greater access to the underlying bony topography and the distal furcation. 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. Contents available in the book .. This will allow the clinician to retain the maximum amount of gingival tissue, including the papilla, which is essential for graft or membrane coverage. Contents available in the book .. 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.
