It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. Conventional surgical approaches include the coronal flap, direct cutaneous incision, and endoscopic techniques. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. Contents available in the book .. Suturing is then performed to stabilize the flaps in their position. 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. In non-esthetic areas with moderate to deep pockets and for crown lengthening, this incision is indicated. It produces a sharp, thin flap margin for adaptation to the bone-tooth junction. Severe hypersensitivity. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. Also, complicated or prolonged surgical procedures that require full-thickness mucoperiosteal flaps with resultant edema can lead to trismus. Following shapes of the distal wedge have been proposed which are, 1. PDF Analysis of Localized Periodontal Flap Surgical Techniques: An Background: Three-dimensional (3D) printing technology is increasingly commercially viable for pre-surgical planning, intraoperative templating, jig creation and customised implant manufacture. In the present discussion, we discussed various flap procedures that are used to achieve these goals. Contents available in the book . 4. After the area to be operated is irrigated with an anti-microbial solution, local anesthesia is applied and the area is isolated after profound anesthesia has been achieved. Apically displaced flap can be done with or without osseous resection. This flap procedure causes the greatest probing depth reduction. Periodontal flap surgeries are also done for the establishment of . 12D blade is usually used for this incision. This incision is always accompanied by a sulcular incision which results in the formation of a collar of gingival tissue which contains the periodontal pocket lining. Flap | PDF | Periodontology | Surgery - Scribd 1. The following statements can be made regarding periodontal regeneration procedures. 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. After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. The flap design may also be dictated by the aesthetic concerns of the area of surgery. Log In or, (Courtesy Dr. Kitetsu Shin, Saitama, Japan. Contents available in the book .. 12 or no. THE UNDISPLACED FLAP TECHNIQUE Step 1: Measure pockets by periodontal probe,and a bleeding point is produced on the outer surface of the gingiva by pocket marker. The apically displaced flap technique is selected for cases that present a minimal amount of keratinized, attached gingiva. 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). This is a modification of the partial thickness palatal flap procedure in which gingivectomy is done prior to the placement of primary and the secondary incision. Contents available in the book .. A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. The crevicular incision, which is also called the second incision, is made from the base of the pocket to the crest of the bone (Figure 57-8). 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. These incisions are made in a horizontal direction and may be coronally or apically directed. The flaps are then apically positioned to just cover the alveolar crest. Step 2: The mucogingival junction is assessed to determine the amount of keratinized tissue. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. The granulation tissue is highly vascularized, so it bleeds profusely. This is mainly because of the reason that all the lateral blood supply to. Root planing is done followed by osseous surgery if needed. May cause attachment loss due to surgery. Journal of clinical periodontology. For the conventional flap procedure, the incisions for the facial and the lingual or palatal flap reach the tip of the interdental papilla or its vicinity, thereby splitting the papilla into a facial half and a lingual or palatal half (Figures 57-3 and 57-4). After suturing, the flap is adapted around the neck of the teeth with the help of moistened gauze. 57: The Periodontal Flap | Pocket Dentistry This preview shows page 166 - 168 out of 197 pages.. View full document. This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. It conserves the relatively uninvolved outer surface of the gingiva. If a full-thickness flap has been elevated, the sutures are placed along the mesial and the distal vertical incision lines to. 2. 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 square, Irrespective of performing any of the above stated surgical procedures, periodontal wound healing always begins with a blood clot in the space maintained by the closed flap after suturing 36. Short anatomic crowns in the anterior region. 3) The insertion of the guide-wire presents PPTX The Flap Technique for Pocket Therapy The margins of the flap are then placed at the root bone junction. This flap procedure allows complete access to the root surfaces allowing their mechanical debridement and decontamination under direct vision. 2. 6. Vertical relaxing incisions are usually not needed. These landmarks establish the presence and width of the attached gingiva, which is the basis for the decision. Closed reduction of the isolated anterior frontal sinus fracture via After this, partial elevation of the flap is done with the help of a small periosteal elevator. It is also known as the mucoperiosteal (mucosal tissue + periosteum) flap. 5. 4. This is termed. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. 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 partial-thickness flap includes only the epithelium and a layer of the underlying connective tissue. After this, the second or the sulcular incision is made from the bottom of the pocket till the crest of the alveolar bone. Swelling is another common complication after flap surgery. Irrespective of performing any of the above stated surgical procedures, periodontal wound healing always begins with a blood clot in the space maintained by the closed flap after suturing 36. Flap for regenerative procedures. The blade is pushed into the sulcus till resistance is felt from the crestal bone crest. This website is a small attempt to create an easy approach to understand periodontology for the students who are facing difficulties during the graduation and the post-graduation courses in our field. Coronally displaced flap. The three incisions necessary for flap surgery. The flap is sutured with interrupted or continuous sling sutures. Step 1:The pockets are measured with the periodontal probe, and a bleeding point is produced on the outer surface of the gingiva to mark the pocket bottom. The flaps may be thinned to allow for close adaptation of the gingiva around the entire circumference of the tooth and to each other interproximally. In case where the soft tissue is quite thick, this incision. 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. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. The initial or internal bevel incision is made (. For the treatment of periodontal pockets with minimal osseous defects, a procedure without or minimal osseous resection is done, whereas, in case of moderate osseous defects and crown lengthening procedures, osseous resection is done with the flap procedure. Click this link to watch video of the surgery: Areas where greater probing depth reduction is required. The original intent of the surgery was to access the root surface for scaling and root planing. This suturing causes the apical positioning of the facial papilla, thus creating open gingival embrasures (black holes). FLAP Flap yaitu suatu lembaran jaringan mukosa yang terdiri dari jaringan gingiva, mukosa alveolar, dan atau jaringan periosteum yang dilepaskan/ dissection dari permukaan tulang alveolar. 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. - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap. Contents available in the book .. Contents available in the book .. 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. Position of the knife to perform the internal bevel incision. In areas with a narrow width of attached gingiva. More is the thickness of the gingiva, farther is the incision placed to include more tissue which needs to be removed. Once the interdental papilla is mobile, a blunt instrument is used to carefully push the interdental papilla through the embrasure. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. The design of the flap is dictated by the surgical judgment of the operator, and it may depend on the objectives of the procedure. This incision is not indicated unless the margin of the gingiva is quite thick. Contents available in the book .. C. According to flap placement after surgery: drg.

The internal beveled incision for the modified Widman flap closely follows the scalloped outline of the dentition to minimize the loss of the attached keratinized gingiva. In Figure 2, the frequency of the types of flap surgical techniques followed were analyzed. Endodontic Topics. Contents available in the book .. Japanese Abstracts | Bone & Joint Papillae are then sutured with interrupted or horizontal mattress sutures. The incision is made . 1 and 2), the secondary inner flap is removed. Periodontal pockets in areas where esthetics is critical. A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. The local anesthetic agent is delivered to achieve profound anesthesia. 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 . Tooth with marked mobility and severe attachment loss. (PDF) 50. The Periodontal Flap | Dr. Syed Wali Peeran - Academia.edu This complete exposure of and access to the underlying bone is indicated when resective osseous surgery is contemplated. 3. An intact papilla should be either excluded or included in the flap. 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. Myocardial infarction / stroke within 6 months. What is a periodontal flap? 2. Laterally displaced flap. The flaps may be thinned to allow for close adaptation of the gingiva around the entire circumference of the tooth and to each other interproximally. The modified Widman flap facilitates instrumentation for root therapy. Following is the description of marginal and para-marginal internal bevel incisions. The scalloping of the incision may not be accentuated as the flap has to be apically displaced and is not adapted interdentally. The researchers reported similar results for each of the three methods tested. To improve esthetics as well as treat periodontal disease the method of choice remains is undisplaced flap surgery [12, 13]. The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. 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. The primary incision is placed with the help of 15c blade, but in case of limited access, blade 12 d can be used. 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). 12 or no. FLAP PERIODONTAL. The presence of thin gingiva which does not allow placement of adequate initial internal bevel incision. The primary objective of the flap surgeries is to gain access to the root surfaces and bone defects so that the deposits on the root surfaces can be eliminated and the granulation tissue can be removed. Access flap for guided tissue regeneration. Methods Twelve patients younger than 18 years with scaphoid nonunion, who underwent a VTMPF procedure without bone grafting , were included for this prospective cohort . No incision is made through the interdental papillae. 1 to 2 mm from the free gingival margin modifed Widman flap or just APICALLY REPOSITIONED FLAP/ PERIODONTAL FLAP SURGICAL TECHNIQUE/ DR.

Periodontal flaps involve the use of horizontal (mesialdistal) and vertical (occlusalapical) incisions. 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. Unsuitable for treatment of deep periodontal pockets. Reconstruction of Distal Phalangeal Soft Tissue Defects with Reverse Homodigital Artery Island Flap, , 2014-11, () . 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. (The use of this technique in palatal areas is considered in the discussion that follows this list. The most apical end of the internal bevel incision is exposed and visible. According to flap reflection or tissue content: C. According to flap placement after surgery: Diagram showing full-thickness and partial-thickness flap. For the management of the papilla, flaps can be conventional or papilla preservation flaps. 1. Evian et al.

This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. PDF F LAP TECHNIQUES FOR POCKET THERAPY - Aligarh Muslim University This approach was described by Staffileno (1969) 23. 7. After the administration of local anesthesia, bone sounding is performed to identify the exact thickness of the gingiva. Persistent inflammation in areas with moderate to deep pockets. It is most commonly caused due to infection and sloughing of blood vessels. The granulation tissue, as well as tissue tags, are then removed. The triangular wedge of the tissue, hence formed is removed. The reasons for placing vertical incisions at line angles of the teeth are. The most abundant cells during the initial healing phase are the neutrophils. B. Sutures are placed to secure the flaps in their position. The key point to be remembered here is, more the thickness of the gingiva more scalloped is the incision. Step 6:Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. Contents available in the book .. 12D blade is usually used for this incision. Moreover, the palatal island flap is the only available flap that can provide keratinized mucosa for defect reconstruction. Periodontal therapy, flap, periodontal flap, full thickness flap, partial thickness flap, nondisplaced flap, displaced flap, conventional flaps, papilla preservation . Flaps in which the interdental papilla is split beneath the contact of two approximating teeth, allowing the reflection of buccal and lingual flaps, are described as the conventional flaps. In this technique no. The apically displaced flap is . The beak-shaped no. 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. Genon and Bender in 1984 27 also reported a similar technique indicated for esthetic purpose. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. 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. These vertical incisions are now joined with a horizontal incision as shown in the following figure. The entire surgical procedure should be planned in every detail before the procedure is initiated. Conventional flaps include: The modified Widman flap, The undisplaced flap, The apically displaced flap, The flap for regenerative procedures. The Modified Widman Flap - Click to Cure Cancer Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap . In another technique, vertical incisions and a horizontal incision are placed. For this reason, the internal bevel incision should be made as close to the tooth as possible (i.e., 0.5mm to 1.0mm) (see Figure 59-1). It is an access flap for the debridement of the root surfaces. It is caused by trauma or spasm to the muscles of mastication. Contents available in the book .. After this, the second incision or the sulcular incision is made from the bottom of the pocket to the crest of the alveolar bone. The process of healing progresses through various phases of . Table 1: showing thickness of gingiva in maxillary tooth region . May cause esthetic problems due to root exposure. Alveolar crest reduction following full and partial thickness flaps. Another important objective of periodontal flap surgery is to regenerate the lost periodontal apparatus. If detected, they are removed. 6. Tooth with extremely unfavorable clinical crown/root ratio. As discussed in, Periodontal treatment of medically compromised patients, antibiotic prophylaxis is must in patients with medical conditions such as rheumatic heart disease. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. the.undisplaced flap and the gingivectomy. The meniscus comma sign has been described for displaced flap tears of the meniscus. This flap procedure may be regarded as internal bevel gingivectomy because the first incision or the internal bevel incision given during this procedure is placed at the level of pocket depth (Figure 62.1), thus including all the soft tissue containing and supporting periodontal pocket.

Areas with sufficient band of attached gingiva. Incisions can be divided into two types: the horizontal and vertical incisions 7. Sulcular incision is now made around the tooth to facilitate flap elevation. The first incision or the internal bevel incision is then made from the bleeding points directed at an apical level to the alveolar crest. The granulomatous tissue is then removed and the deposits on the root surfaces are removed by scaling. 61: Periodontal Regeneration and Reconstructive Surgery, 63: Periodontal Plastic and Esthetic Surgery, 59: The Flap Technique for Pocket Therapy, 55: General Principles of Periodontal Surgery, 31: Radiographic Aids in the Diagnosis of Periodontal Disease. Step 2:The gingiva is reflected with a periosteal elevator (Figure 59-3, D). The continuous sling suture has an advantage that it uses tooth as an anchor and thus, facilitates to hold the flap edges at the root-bone junction. One incision is now placed perpendicular to these parallel incisions at their distal end. The area is then irrigated with normal saline and flaps are adapted back in position. This incision, together with the initial reverse bevel incision, forms a V-shaped wedge that ends at or near the crest of bone. The flap is placed at the toothbone junction by apically displacing the flap. Mitral facies or malar flush There is a tapping apex beat which is undisplaced. The esthetic and functional demands of maxillofacial reconstruction have driven the evolution of an array of options. Although some details may be modified during the actual performance of the procedure, detailed planning allows for a better clinical result. Two types of horizontal incisions have been recommended: the internal bevel incision.
