A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. 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 Undisplaced Flap - Periodontal Disease - Click to Cure Cancer In this technique no. Diagram showing the location of two different areas where the internal bevel incision is made in an undisplaced flap. These, Historically, gingivectomy was the treatment of choice for these areas until 1966, when Robinson 32 addressed this problem and gave a separate surgical procedure for these areas which he termed, The triangular wedge technique is used in cases where the adequate zone of attached gingiva is present and in cases of short or small tuberosity. The incisions given are the same as in case of modified Widman flap procedure. In this flap procedure, no ostectomy is performed; however, minor osetoplasty may be done to modify the undesired bony architecture. Platelets rich fibrin (PRF) preparation and application in the . We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. The vertical incision should be made in such a way that interdental papilla is completely preserved. The interdental papilla is then freed from the underlying bone and is completely mobilized. Alveolar crest reduction following full and partial thickness flaps. Contents available in the book .. Need to visually examine the area, to make a definite diagnosis. Incisions used in papilla preservation flap using primary, secondary and tertiary incisions. In the following discussion, we shall study in detail, the surgical techniques that are followed in various flap procedures. The internal bevel incision is basic to most periodontal flap procedures. These incisions are made in a horizontal direction and may be coronally or apically directed. The aim of this review is to determine the use of 3D printed technologies in the treatment of scaphoid fractures. Periodontal pockets in severe periodontal disease. It is an access flap for the debridement of the root surfaces. The secondary. In areas with a narrow width of attached gingiva. This incision is indicated in the following situations. 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. PDF Analysis of Localized Periodontal Flap Surgical Techniques: An . The following steps outline the undisplaced flap technique. The surgical approaches that split the papilla cause shrinkage and decrease in the height of the interdental papilla leading to the exposure of interproximal embrasures. May increase the risk of root caries. PDF Periodontics . Flap Surgery 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. The undisplaced (unrepositioned) flap improves accessibility for instrumentation, but it also removes the pocket wall, thereby reducing or eliminating the pocket. Persistent inflammation in areas with moderate to deep pockets. Contents available in the book .. Sixth day: (10 am-6pm); "Perio-restorative surgery" Coronally displaced flap Connective tissue autograft Free gingival graft Laterally positioned flap Apically displaced flap 5. Swelling hinders routine working life of patient usually during the first 3 days after surgery 41. 1. This is mainly because of the reason that all the lateral blood supply to . 2006 Aug;77(8):1452-7. 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 following outline of this technique: Contents available in the book .. A small periosteal elevator or Molt 2/4 curette can be used for this purpose. PDF Case Report Idiopathic Gingival Fibromatosis Rehabilitation: A Case It is most commonly caused due to infection and sloughing of blood vessels. Contents available in the book . As described in, Image showing primay and secondary incisions used in ledge and wedge technique. Following shapes of the distal wedge have been proposed which are, 1. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. Preservation of good blood supply to the flap is another important consideration. In this technique, two incisions are made with the help of no. It conserves the relatively uninvolved outer surface of the gingiva. Genon and Bender in 1984 27 also reported a similar technique indicated for esthetic purpose. This flap procedure causes the greatest probing depth reduction. The granulation tissue, as well as tissue tags, are then removed. The Orban knife is usually used for this incision. A new technique for arthroscopic meniscectomy using a traction suture, , 2015-02, ()KCI . Chlorhexidine rinse 0.2% bid . Contents available in the book . The coronally directed incision is designated as external bevel incision whereas the apically directed incisions are the internal bevel and sulcular incision. 1. Internal bevel and is 0.5-1.0mm from gingival margin Modified Widman Flap The bleeding is frequently associated with pain. (1995, 1999) 29, 30 described . 12 or no. . 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. Periodontal pockets in areas where esthetics is critical. May cause hypersensitivity. In areas with thin gingiva and alveolar process. Another important objective of periodontal flap surgery is to regenerate the lost periodontal apparatus. The triangular wedge of the tissue, hence formed is removed. Contents available in the book .. Periodontal flap surgeries are also done for the establishment of . The modified Widman flap has been described for exposing the root surfaces for meticulous instrumentation and for the removal of the pocket lining.6 Again, it is not intended to eliminate or reduce pocket depth, except for the reduction that occurs during healing as a result of tissue shrinkage. The incision is made . The partial-thickness flap is indicated when the flap is to be positioned apically or when the operator does not want to expose bone. This is termed. This flap procedure causes the greatest probing depth reduction. During this whole procedure, the placement of the primary incision is very important because if improperly given it may become short, leaving exposed bone or may become longer requiring further trimming which is difficult. Papillae are then sutured with interrupted or horizontal mattress sutures. 6. Ramfjord and Nissle6 performed an extensive longitudinal study that compared the Widman procedure (as modified by them) with the curettage technique and the pocket elimination methods, which include bone contouring when needed. 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. In this flap, only epithelium and the underlying connective tissue are reflected, leaving the periosteum intact. The blood clot provides a framework for the proliferation and migration of cells from surrounding tissues including gingiva, periodontal ligament (PDL), cementum, and alveolar bone 38. Conventional flaps include the. 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 (, Tissue tags and granulation tissue are removed with a curette.

The information presented in this website has been collected from various leading journals, books and websites. 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 Patients at high risk for caries. A technique using a mixture of bone dust and blood is called as a. bone blend technique b. bone swaging technique Periodontal flap surgery with conventional incision commonly results in gingival recession and loss of interdental papillae after treatment. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. Contents available in the book .. 7. One technique includes semilunar incisions which are . More is the thickness of the gingiva, farther is the incision placed to include more tissue which needs to be removed. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. The most abundant cells during the initial healing phase are the neutrophils. 3. 3. Journal of clinical periodontology. PPTX The Flap Technique for Pocket Therapy Fibrous enlargement is most common in areas of maxillary and mandibular . 7. 300+ TOP Periodontics MCQs and Answers Quiz [Latest] In this flap procedure, all the soft tissue, including the periosteum is reflected to expose the underlying bone. Once the interdental papilla is mobile, a blunt instrument is used to carefully push the interdental papilla through the embrasure. 15c, 11 or 12d. After this, the second or the sulcular incision is made from the bottom of the pocket till the crest of the alveolar bone. Myocardial infarction / stroke within 6 months. 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. Gain access for osseous resective surgery, if necessary, 4. Along with removing the tissue above the alveolar crest, this incision also reveals the thickness of the soft tissue. Undisplaced flap, The incision is usually carried to a point apical to the alveolar crest, depending on the thickness of the tissue. A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. perio1 Flashcards by Languages | Brainscape 15 scalpel blade is used to make a triangular incision distal to the molar on retromolar pad area or the maxillary tuberosity. 15c or No. The most apical end of the internal bevel incision is exposed and visible. The patient is recalled after one week for suture removal. 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. Suturing is then done using a continuous sling suture. Contents available in the book .. Step 3: The second, or crevicular, incision is made from the bottom of the pocket to the bone to detach the connective tissue from the bone. Contents available in the book .. This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. 4. The main objective of periodontal flap surgical procedures is to allow access for the cleaning of the roots of teeth and the removal of the periodontal pocket lining, as well as to treat the irregularities of the alveolar bone, so that when gingiva is repositioned around the teeth, it will allow for the reduction of pockets, infections, and inflammation. The papillae are then carefully pushed back through the interdental embrasures to palatal or lingual aspect. In case where the soft tissue is quite thick, this incision. With this incision, the gingiva containing pocket lining is separated from the tooth surface. The area is then irrigated with an antimicrobial solution. The deposits on the root surfaces are removed and root planing is done. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. Because the alveolar bone is partially exposed, there is minimum post-operative pain and swelling. periodontal flaps docx - Dr. Ruaa - Muhadharaty Areas where greater probing depth reduction is required. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. As the flap is to be placed in an apical position, vertical incisions are made extending beyond the mucogingival junction. If extensive osseous recontouring is planned, an exaggerated incision is given. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva.
