Undisplaced femoral neck fractures in children have a high risk of secondary displacement. One technique includes semilunar incisions which are . Pockets around the teeth in which a complete removal of root irritants is not clinically possible without gaining complete access to the root surfaces. After the removal of the secondary flap, scaling and root planing is done and the flap is adapted to its position. Semiconductor chip assemblies, methods of making same and components for sameSemiconductor chip assemblies, methods of making same and components for same .. .. . Two basic flap designs are used. Suturing is then performed to stabilize the flaps in their position. 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. 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. (1985) 26 modified this procedure to preserve anterior esthetics after flap surgery. International library review - 2022-2023| , , & - Academic Accelerator Sixth day: (10 am-6pm); "Perio-restorative surgery" 5. Contents available in the book .. Furthermore, the access to the bone defects facilitates the execution of various regenerative procedures. HGF is characterized as a benign, slowly progressive, nonhemorrhagic, fibrous enlargement of keratinized gingiva.It can cover teeth in various degrees, and can lead to aesthetic disfigurement. The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. 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. The horizontal incisions are used to separate the gingiva from the root surfaces of teeth. The blade is introduced into the sulcus or pocket and is inserted as far as possible into the interdental space around the tooth, keeping it close to the crown. This incision, together with the initial reverse bevel incision, forms a V-shaped wedge that ends at or near the crest of bone. Patients at high risk for caries. In 1973, App 25 reported a similar technique and termed it as Intact Papilla Flap which retained the interdental gingiva in the buccal flap. At last periodontal dressing may be applied to cover the operated area. So, this procedure cannot be employed when modified Widman flap, excisional new attachment procedure and regenerative procedures such as osseous grafting are done because these procedures require primary closure.

Smaller incisions usually cause less postoperative swelling and pain as compared to larger incisions. The three incisions necessary for flap surgery. Contents available in the book . 6. a. Full-thickness flap. If extensive osseous recontouring is planned, an exaggerated incision is given. 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 . The most apical end of the internal bevel incision is exposed and visible. The secondary flap removed, can be used as an autogenous connective tissue graft. Within the first few days, monocytes and macrophages start populating the area 37. Otherwise, the periodontal dressing may be placed. 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. Step 5:Tissue tags and granulation tissue are removed with a curette. The flaps are then apically positioned to just cover the alveolar crest. Chlorhexidine rinse 0.2% bid . Deep intrabony defects. Flap design for a conventional or traditional flap technique. 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. 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. - Charter's method - Bass method - Still man method - Both a and b correct . This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap. These are indicated in cases where interdental spaces are too narrow and when the flap needs to be displaced. This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. In the present discussion, we discussed various flap procedures that are used to achieve these goals. These landmarks establish the presence and width of the attached gingiva, which is the basis for the decision. Unsuitable for treatment of deep periodontal pockets. 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. Contents available in the book . Areas which do not have an esthetic concern. In the following discussion, we shall study in detail, the surgical techniques that are followed in various flap procedures. Several techniques can be used for the treatment of periodontal pockets. This incision is indicated in the following situations. The flap is sutured with interrupted or continuous sling sutures. 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. 4. The aim of this review is to determine the use of 3D printed technologies in the treatment of scaphoid fractures. 2. The square . 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. Contents available in the book . The vertical incisions are made from the center of palatal/lingual surfaces of teeth extending palatally/lingually. a. Coronally displaced flap Connective tissue autograft Free gingival graft Laterally positioned flap Apically displaced flap 5. Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. See video of the surgery at: Modified flap operation. Wood DL, Hoag PM, Donnenfeld OW, Rosenfeld LD. With the migration of these cells in the healing area, the process of re-establishment of the dentogingival unit progresses. A. 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. B. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. The incision is usually scalloped to maintain gingival morphology and to retain as much papilla as possible. The bone remains covered by a layer of connective tissue that includes the periosteum. The flap design may also be dictated by the aesthetic concerns of the area of surgery. May cause hypersensitivity. The internal bevel incision is basic to most periodontal flap procedures. Click this link to watch video of the surgery: Areas where greater probing depth reduction is required. Although some details may be modified during the actual performance of the procedure, detailed planning allows for a better clinical result. preservation flap ) papila interdental tidak terpotong karena tercakup ke salah satu flep (gambar 2C).

The incision is made around the entire circumference of the tooth using blade No. Fundamental principles in periodontal plastic surgery and mucosal augmentationa narrative review. 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). Hence, this suturing is mainly indicated in posterior areas where esthetics. Step 1:The initial incision is an internal bevel incision to the alveolar crest starting 0.5mm to 1mm away from the gingival margin (Figure 59-3, C). The most abundant cells during the initial healing phase are the neutrophils. The partial-thickness flap includes only the epithelium and a layer of the underlying connective tissue. 1. Periodontal therapy, flap, periodontal flap, full thickness flap, partial thickness flap, nondisplaced flap, displaced flap, conventional flaps, papilla preservation . References are available in the hard-copy of the website. The starting point on the gingiva is determined by whether the flap is apically displaced or not displaced (Figure 57-7). The palatal flap offers a technically simple and predictable option for intraoral reconstruction. Root planing is done followed by osseous surgery if needed. 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. Contents available in the book .. 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 first step . 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. 6. In case of generalized chronic periodontitis with localized gingival overgrow th,undisplaced flap with internal bevel incision has given better results esthetically and structurally .Thus with th is approach there is improvement in periodontal health along with good esthetics. The blade should be kept on the vertical height of the alveolus so that palatal artery is not injured. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. This incision is indicated in the following situations. The original intent of the surgery was to access the root surface for scaling and root planing. 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. Areas where post-operative maintenance can be most effectively done by doing this procedure. 6. Later on Cortellini et al. UNDISPLACEDFLAP |Also known as internal bevel gingivectomy |Differs from the modified widman flap inthat pocket wall is removed with the initial incision TECHNIQUE |Pockets are measured with a pocket marker & a bleeding point is created THE INITIAL INTERNAL BEVEL INCISION IS CARRIED APICAL TO THE CREST OF BONE CONTD. Areas with sufficient band of attached gingiva. Long-term outcome of undisplaced fatigue fractures of the femoral neck in young male adults; In this technique, two incisions are made with the help of no. Sulcular incision is now made around the tooth to facilitate flap elevation. The root surfaces are checked and then scaled and planed, if needed (Figure 59-3, G and H). 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 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. With the help of Ochsenbein chisels (no. The classic treatment till today in developing countries is removal of excess gingival growth by scalpel but one should remember about the periodontal treatment which should be done before commencing the surgical part of . These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. 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. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. 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). 15c, 11 or 12d. The beak-shaped no. 1. Interrupted or continuous sling sutures are then placed to secure the flaps in their place. 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. 7. 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. 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. The internal bevel incisions are typically used in periodontal flap surgeries. This flap procedure causes the greatest probing depth reduction. 2. 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. 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. 12 or no. The term gingival ablation indicates? This incision is made from the crest of the gingival margin till the crest of alveolar bone. The distance of the incision from the gingival margin (thickness of the incision) varies according to the pocket depth, the thickness of the gingiva, width of the attached gingiva, shape and contour of gingival margins and whether or not the operative area is in the esthetic zone. 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. A detailed description of the historical aspect of various flap surgeries has been given in the previous chapter. Both full-thickness and partial-thickness flaps can also be displaced. 15 or 15C surgical blade is used most often to make this incision. The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. After this, the second or the sulcular incision is made from the bottom of the pocket till the crest of the alveolar bone. 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: The following statements can be made regarding periodontal regeneration procedures. This incision is made on the buccal aspect of the tooth till the desired level, sparing the interdental gingiva. 5. 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. in 1985 28 introduced a detailed description of the surgical approach reported earlier by Genon and named the technique as Papilla Preservation Flap. The incisions given are the same as in case of modified Widman flap procedure. 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. Flap adaptation is then done with the help of moistened gauze and any excess blood is expressed. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. The patients were assigned randomly to one of the techniques, and results were analyzed yearly for up to 7 years after therapy. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. Which of the following mucogingival surgical techniques is indicated in areas of narrow gingival recession adjacent to a wide band of attached gingiva that can be used as a donor site? free gingival autograft double papilla flap modified Widman flap laterally displaced (positioned . It conserves the relatively uninvolved outer surface of the gingiva. Contents available in the book .. 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. Scaling, root planing and osseous recontouring (if required) are carried out. 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. The following steps outline the undisplaced flap technique: Step 1: The pockets are measured with the periodontal probe. According to flap reflection or tissue content: C. According to flap placement after surgery: Diagram showing full-thickness and partial-thickness flap. After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective. 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. One of the most common complication after periodontal flap surgery is post-operative bleeding. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. Contents available in the book . Contents available in the book . The interdental incision is then given to remove the wedge of tissue that contains the pocket wall. Contents available in the book .. According to flap reflection or tissue content: ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. Contraindications of periodontal flap surgery. 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. These techniques are described in detail in. 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. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva.

Contents available in the book .. The vertical incision must extend beyond the mucogingival line, reaching the alveolar mucosa, to allow for the release of the flap to be displaced. 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. Following is the description of these flaps. Areas where greater probing depth reduction is required. This procedure was aimed to provide maximum protection to osseous and transplant recipient sites. As already stated, this technique is utilized when thicker gingiva is present. 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. Contents available in the book . b. The internal bevel incision starts from a designated area on the gingiva, and it is then directed to an area at or near the crest of the bone (Figure 57-6). There is a loud S1 The murmur is a mid-diastolic rumbling heard best at . The local anesthetic agent is delivered to achieve profound anesthesia. Platelets rich fibrin (PRF) preparation and application in the . b. Split-thickness flap. This drawback of conventional flap techniques led to the development of this flap technique which intended to spare the papilla instead of splitting it. The periosteum left on the bone may also be used for suturing the flap when it is displaced apically. 2014 Apr;41:S98-107. Conventional flaps include the. The incision is carried around the entire tooth. Burkhardt R, Lang NP. The area is then irrigated with an antimicrobial solution. Connective tissue grafting harvesting techniques as well as free gingival graft. 6. Contents available in the book .. Contents available in the book . 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. Clinical crown lengthening in multiple teeth. In the upcoming chapters, we shall read about various regenerative procedures which are aimed at achieving regeneration of lost periodontal structures. In the present discussion, we shall study in detail, the current concepts and advances in various periodontal flap surgeries. Fractures of the frontal sinus are a common maxillofacial trauma and constitute 5-15% of all maxillofacial fractures. 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. APICALLY REPOSITIONED FLAP/ PERIODONTAL FLAP SURGICAL TECHNIQUE/ DR. ANKITA KOTECHA 17,228 views Jul 30, 2020 This video is about APICALLY REPOSITIONED FLAP .more Dislike Share dental studies. 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. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. Contents available in the book .. Contents available in the book .. We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. In case where the soft tissue is quite thick, this incision. Normal interincisal opening is approximately 35-45mm, with mild . Areas where greater probing depth reduction is required. If detected, they are removed. The undisplaced (unrepositioned) flap improves accessibility for instrumentation, but it also removes the pocket wall, thereby reducing or eliminating the pocket. Step 2: The initial, internal bevel incision is made after the scalloping of the bleeding marks on the gingiva. a. Non-displaced flap. Ahmad Syaify, Sp.Perio (K) Spesialis Konsultan Bedah Perio & Estetik. This suturing causes the apical positioning of the facial papilla, thus creating open gingival embrasures (black holes). 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. 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. Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . The main advantages of this procedure are the preservation of maximum healthy tissue and minimum post-operative discomfort to the patient.
