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 Need to visually examine the area, to make a definite diagnosis. The most apical end of the internal bevel incision is exposed and visible. 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 distal wedge operation. Refer to oral surgeon for biopsy ***** B. 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 partial-thickness flap is indicated when the flap is to be positioned apically or when the operator does not want to expose bone. After the area to be operated has been irrigated with an antimicrobial solution and isolated, the local anesthetic agent is delivered to achieve profound anesthesia. The base of the flap should be wider than the flap margin so that the blood supply to the flap is not jeopardized. Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. Contents available in the book .. 2006 Aug;77(8):1452-7. In the following discussion, we shall study in detail, the surgical techniques that are followed in various flap procedures. 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. Incisions used in papilla preservation flap using primary and secondary incisions. Contraindications of periodontal flap surgery. Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap . It was described by Kirkland in 1931 31. Its final position is not determined by the placement of the first incision. 16: 199-203 . The periosteum left on the bone may also be used for suturing the flap when it is displaced apically. The papilla preservation flap incorporates the entire papilla in one of the flaps by means of crevicular interdental incisions to sever the connective tissue attachment as well as a horizontal incision at the base of the papilla to leave it connected to one of the flaps. Severe hypersensitivity. It differs from the modified Widman llap in that the soft tissue pocket wall is removed with the initial incision; thus it may be considered an internal bevel glngivectomy. In areas with shallow periodontal pocket depth. the.undisplaced flap and the gingivectomy. 4. Click this link to watch video of the surgery: Modified Widman Flap surgery. Pockets around the teeth in which a complete removal of root irritants is not clinically possible without gaining complete access to the root surfaces. This type of incision, starting just below the bleeding points, removes the pocket wall completely. (1985) 26 modified this procedure to preserve anterior esthetics after flap surgery. The partial-thickness flap may be necessary when the crestal bone margin is thin and exposed with an apically placed flap or when dehiscences or fenestrations are present. 15c or No. The operated area will be cleaner without dressing and will heal faster. 6. It differs from the modified Widman flap in that the soft-tissue pocket wall is removed with the initial incision; thus, it may be considered an internal bevel gingivectomy. The undisplaced flap and the gingivectomy are the two techniques that surgically remove the pocket wall. Undisplaced flap, When the flap is placed apically, coronally or laterally to its original position. Step 5:Tissue tags and granulation tissue are removed with a curette. The crevicular incision is then placed from the bottom of the pocket till the alveolar crest. 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. This incision is not indicated unless the margin of the gingiva is quite thick. Laterally displaced flap. 2. The objectives for the other two flap proceduresthe undisplaced flap and the apically displaced flapinclude root surface access and the reduction or elimination of the pocket depth. The triangular wedge of the tissue, hence formed is removed. 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. Periodontal maintenance (Supportive periodontal therapy), Orthodontic-periodontal interrelationship, Piezosurgery in periodontics and oral implantology. 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 deposits on the root surfaces are removed and root planing is done. After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. The initial or internal bevel incision is made (. The interdental incision is then made to severe the inter-dental fiber attachment. Contents available in the book .. 2. The local anesthetic agent is delivered to achieve profound anesthesia. The location of the primary incision is based on the thickness of the gingiva, width of attached gingiva, the contour of the gingival margins, surgical objectives, and esthetic considerations. No incision is made through the interdental papillae. This type of flap is also called the split-thickness flap. News & Perspective Drugs & Diseases CME & Education Contents available in the book .. This suturing causes the apical positioning of the facial papilla, thus creating open gingival embrasures (black holes). The vertical incisions are made from the center of palatal/lingual surfaces of teeth extending palatally/lingually. Incisions can be divided into two types: the horizontal and vertical incisions, Basic incisions used in periodontal surgeries, This internal bevel incision is placed at a distance from the gingival margin, directed towards the alveolar crest. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. 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. The granulomatous tissue is then removed and the deposits on the root surfaces are removed by scaling. After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective. a. Non-displaced flap. 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). The following outline of this technique: Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. Enter the email address you signed up with and we'll email you a reset link. Contents available in the book .. The incision is usually carried to a point apical to the alveolar crest, depending on the thickness of the tissue. The aim of this review is to determine the use of 3D printed technologies in the treatment of scaphoid fractures. Long-term outcome of undisplaced fatigue fractures of the femoral neck in young male adults; It is the incision from which the flap is reflected to expose the underlying bone and root. Fractures of the frontal sinus are a common maxillofacial trauma and constitute 5-15% of all maxillofacial fractures. Ramfjord SP, Nissle RR. The area is then irrigated with normal saline and flaps are adapted back in position. This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. Disain flep ini memberikan estetis pasca bedah yang lebih baik, dan memberikan perlindungan yang lebih baik terhadap tulang interdental, hal mana penting sekali dalam tehnik bedah yang mengharapkan terjadinya regenerasi jaringan periodontium. After this, the second incision or the sulcular incision is made from the bottom of the pocket to the crest of the alveolar bone. In Figure 2, the frequency of the types of flap surgical techniques followed were analyzed. The most abundant cells during the initial healing phase are the neutrophils. Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. Ramfjord and Nissle 8 in 1974, modified the original Widman flap procedure . Rough handling of the tissue and long duration of the surgery commonly result in post-operative swelling. Conventional flaps include: The modified Widman flap, The undisplaced flap, The apically displaced flap, The flap for regenerative procedures. There is a loud S1 The murmur is a mid-diastolic rumbling heard best at . Modified Widman flap and apically repositioned flap. Following shapes of the distal wedge have been proposed which are, 1. Preservation of good blood supply to the flap is another important consideration. Contents available in the book .. Once the interdental papilla is mobile, a blunt instrument is used to carefully push the interdental papilla through the embrasure. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. 3. Contents available in the book .. Contents available in the book .. The no. Contents available in the book .. The internal bevel incision in an undisplaced flap procedure is started at the same point where an external bevel incision is started in agingivectomyprocedure. 1. Contents available in the book .. The most abundant cells during the initial healing phase are the neutrophils. Contents available in the book .. Tooth with extremely unfavorable clinical crown/root ratio. 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. 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). Contents available in the book . When the flap is returned and sutured in its original position. 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 basic clinical steps followed during this flap procedure are as follows. Vertical relaxing incisions are usually not needed. The gingival margin is removed, and the flap is reflected to gain access for root therapy. Different Flap techniques for treatment of gingival recession (Lateral-coronal-double papilla-semilunar-tunnel-apical). A full-thickness flap is elevated with the help of a periosteal elevator whereas partial-thickness flap is elevated using sharp dissection with a Bard-Parker knife. The granulation tissue, as well as tissue tags, are then removed. The meniscus comma sign has been described for displaced flap tears of the meniscus. Contents available in the book .. The intrasulcular incision is given using No. With the conventional flap, the interdental papilla is split beneath the contact point of the two approximating teeth to allow for the reflection of the buccal and lingual flaps. It is indicated when the flap has to be positioned apically and when the exposure of the bone is not required. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. The vertical incision must extend beyond the mucogingival line, reaching the alveolar mucosa, to allow for the release of the flap to be displaced. Contents available in the book .. 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? that still persist between the bottom of the pocket and the crest of the bone. (2010) Factor V Leiden Mutation and Thrombotic Occlusion of Microsurgical Anastomosis After Free TRAM Flap. Conventional flaps include the. It reduces mouth opening, is commonly associated with pain and causes difficulty in mastication. The vertical incision should always be placed at the line angles of the teeth and never (except rare instances, such as a double papilla flap) over the height of contour of the root. Possibility of exposure of furcations and roots, which complicates postoperative supragingival plaque control. Step 2: The mucogingival junction is assessed to determine the amount of keratinized tissue. 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. ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. 2. The area to be operated is then isolated with the help of gauge. The interdental papilla is then freed from the underlying bone and is completely mobilized. Contents available in the book .. Contents available in the book . The original intent of the surgery was to access the root surface for scaling and root planing. Contents available in the book .. This incision is made from the crest of the gingival margin till the crest of alveolar bone. Areas which do not have an esthetic concern. The blade should be kept on the vertical height of the alveolus so that palatal artery is not injured. In this flap procedure, no ostectomy is performed; however, minor osetoplasty may be done to modify the undesired bony architecture. After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades . 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. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. In areas with deep periodontal pockets and bone defects. May cause esthetic problems due to root exposure. This is also known as. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. (The use of this technique in palatal areas is considered in the discussion that follows this list. The starting point on the gingiva is determined by whether the flap is apically displaced or not displaced (Figure 57-7). Contents available in the book .. Periodontal flaps can be classified on the basis of the following: For bone exposure after reflection, the flaps are classified as either full-thickness (mucoperiosteal) or partial-thickness (mucosal) flaps (Figure 57-1). This internal bevel incision is placed at a distance from the gingival margin, directed towards the alveolar crest. preservation flap ) papila interdental tidak terpotong karena tercakup ke salah satu flep (gambar 2C). The bleeding is frequently associated with pain. Takei et al. Step 6:Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. Scalloping required for the different types of flaps (see, The apically displaced flap technique is selected for cases that present a minimal amount of keratinized, attached gingiva. In addition, thinning of the flap should be performed with the initial incision, because it is easier to accomplish at this time than it is later with a loose, reflected flap that is difficult to manage. Laparoscopic technique for secondary vaginoplasty in male to female transsexuals using a modified . 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. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. Hence, this suturing is mainly indicated in posterior areas where esthetics. Areas which do not have an esthetic concern. 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.4 Although this is usually not clinically significant,7 the differences may be significant in some cases (Figure 57-2). 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. With the migration of these cells in the healing area, the process of re-establishment of the dentogingival unit progresses. Flap design for a conventional or traditional flap technique. 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. Interrupted or continuous sling sutures are then placed to secure the flaps in their place. 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. Several techniques can be used for the treatment of periodontal pockets. The incision is started from the greatest scallop of the gingiva around the tooth, which is usually present little distal to the mid-axis of the tooth in case of maxillary incisors and canines. Trismus is the inability to open the mouth. These . Fugazzotto PA. 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. After debridement, flaps are closely adapted around the teeth in close approximation, allowing healing by primary intention. Burkhardt R, Lang NP. 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. 2. The periodontal flap is one of the most frequently employed procedures, particularly for moderate and deep pockets in posterior areas (see, Increase accessibility to root deposits for scaling and root planing, Eliminate or reduce pocket depth via resection of the pocket wall, Gain access for osseous resective surgery, if necessary, Expose the area for the performance of regenerative methods, Technique for Access and Pocket Depth Reduction or Elimination, All three flap techniques that were just discussed involve the use of the basic incisions described in. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. It is an access flap for the debridement of the root surfaces. Following is the description of these flaps. 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. 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. drg. Connective tissue grafting harvesting techniques as well as free gingival graft. The bone remains covered by a layer of connective tissue that includes the periosteum. 2. Clin Appl Thromb Hemost. The palatal flap offers a technically simple and predictable option for intraoral reconstruction. 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. A. The key point to be remembered here is, more the thickness of the gingiva more scalloped is the incision. At last periodontal dressing may be applied to cover the operated area. It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. Periodontal flaps can be classified as follows. To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. The step-by-step technique for the undisplaced flap is as follows: Step 1: The periodontal probe is inserted into the gingival crevice & penetrates the junctional epithelium & connective tissue down to bone. The bleeding may range from a minor leakage or oozing, to extensive or frank bleeding at the surgical site. The granulation tissue is removed from the area and scaling and root planing is done. This is mainly because of the reason that all the lateral blood supply to . This is especially important because, on the palatal aspect, osseous deformities such as heavy bone ledges and exostoses are commonly seen. The reduction of bacterial load and inflammation minimizes further loss of tooth-supporting structures and thus aid in the better prognosis of teeth, provided, the patient stays on a strict maintenance schedule. Genon and Bender in 1984 27 also reported a similar technique indicated for esthetic purpose. 3. The modified Widman flap facilitates instrumentation for root therapy. After this, partial elevation of the flap is done with the help of a small periosteal elevator. Re-inspection of the operated area is done to check for any deposits on the root surfaces, remaining granulation tissue or tissue tags which are removed, if detected. Two types of horizontal incisions have been recommended: the internal bevel incision,6 which starts at a distance from the gingival margin and which is aimed at the bone crest, and the crevicular incision, which starts at the bottom of the pocket and which is directed to the bone margin. 6. The most apical end of the internal bevel incision is exposed and visible. 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. This flap procedure causes the greatest probing depth reduction. Also, complicated or prolonged surgical procedures that require full-thickness mucoperiosteal flaps with resultant edema can lead to trismus. An electronic search without time or language restrictions was . 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. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. These vertical incisions are now joined with a horizontal incision as shown in the following figure. Along with removing the tissue above the alveolar crest, this incision also reveals the thickness of the soft tissue. Placing periodontal depressing is optional. Contents available in the book . 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. 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. Which is the best method of brushing technique preferred for the patient with orthodontic appliance: ? 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. Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . All three flap techniques that were just discussed involve the use of the basic incisions described in Chapter 57: the internal bevel incision, the crevicular incision, and the interdental incision. 74. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. 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 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. The techniques that are used to achieve reconstructive and regenerative objectives are the papilla preservation flap8 and the conventional flap, which involve only crevicular or pocket incisions. 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. 5. Contents available in the book .. This incision has also been termed the first incision, because it is the initial incision for the reflection of a periodontal flap; it has also been called the reverse bevel incision, because its bevel is in reverse direction from that of the gingivectomy incision. Increase accessibility to root deposits for scaling and root planing, 2. Apically-displaced Flap 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, Periodontal flap surgeries are also done for the establishment of.

Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. It can be used in combination with other procedures such as osseous resection, regenerative procedures, hemisection procedure and procedures involving wedge excision. Palatal flaps cannot be displaced because of the absence of unattached gingiva. This is mainly because of the reason that all the lateral blood supply to. This is termed. According to flap reflection or tissue content: 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. Unsuitable for treatment of deep periodontal pockets. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. As already stated, this technique is utilized when thicker gingiva is present. In this flap, only epithelium and the underlying connective tissue are reflected, leaving the periosteum intact. Ahmad Syaify, Sp.Perio (K) Spesialis Konsultan Bedah Perio & Estetik. The secondary incision is given from the depth of the periodontal pocket till the alveolar crest.
