With an apically positioned flap, the crown length of the impacted tooth is longer than normal due to apical migration of the gingival margin. The crown lengths of teeth uncovered with closed eruption were similar to contralateral nonimpacted teeth in the same mouth.
Although an apically positioned flap for uncovering was adapted with an effort, minimal keratinized tissue and an irregular soft-tissue contour over the mesiobuccal side were still noted following tooth eruption. For highly impacted teeth, a second soft-tissue correction such as keratinized tissue augmentation or gingivoplasty may be necessary.
The contraindications for the apically positioned flap include root hypersensitivity, high rate of root caries, esthetic limitations, anatomic limitations, inadequate clinical attachment, and deep infrabony defects. 1. Clinical crown lengthening is a surgical procedure to increase the amount of exposed tooth structure.

was bonded to the impacted tooth at the time of the surgical exposure; pins were placed in two teeth, both in the CE group. Light, con- tinuous orthodontic forces were applied about 2 weeks after the uncovering in all cases. Surgical techniques The apically positioned flap is a split-thick- ness pedicle reflected from the edentulous.
[ Top ] Discussion. During orthodontic treatment, it is particularly important to maintain a healthy band of keratinized gingiva around a labially positioned canine, otherwise the mobile tissue around the tooth may strip away from the crown and root surface leaving a periodontal defect. 11,14,17,18,22 An adequate band of attached gingiva can be achieved by either apically repositioning.

When impacted teeth need a facial (labial or buccal) approach, and the position of tooth is deep, closed eruption is an option. In the aforementioned situation, an apically positioned flap will not be stable and rebound of soft tissue may occur in addition to unwanted exposed parts of the bone that should be covered.
Maxillary canines are the second most commonly impacted teeth after mandibular 3rd molars 1/3 are labially impacted; 2/3 are palatal! My practice legacy, Dr.Mathews and Dr.Kokich teach us that if the tip is near or apical to the adjacent CEJ, an apically positioned flap or closed eruption should be considered.
Excisional uncovering of labially impacted canines was reported to result in less-favorable periodontal outcomes, whereas labially impacted canines uncovered with the apically positioned flap technique seemed to show periodontal outcomes comparable with those of untreated teeth; none of the included studies examined the periodontal outcome.
In the present case, a labially impacted maxillary left canine was surgically exposed using an apically positioned flap. Orthodontic extrusion was carried out further. Maxillary canines are one of the most common teeth that are impacted among patients seeking orthodontic treatment.
Surgical approach 1. Layer to layer technique applied for contour augmentation on posterior buccal site. 2. Bed preparation has been done simulationally for Apically positioned.
The creation and preservation of the band of attached gingiva is very critical for periodontal health in the management of labially impacted teeth [12]. The only technique that predictably would produce more gingiva is an apically positioned flap, if there were insufficient gingiva in the area of the canine.

Vermette - Uncovering labially impacted teeth: apically positioned flap and closed eruption The purpose of this study was to examine the esthetic and periodontal differences between two methods of uncovering labially impacted maxillary anterior teeth: the apically positioned flap and closed-eruption techniques.
apically positioned flaps. 3 A case is presented here of a method of using palatal keratinized mucosa in a modified apically repositioned flap to provide a successful marginal gingival seal for unerupted maxillary incisor teeth. CASE REPORT A 12-year-old girl was referred by her general dental practitioner to the department of orthodontics.
Flap replaced apically----We don't just do this flap on its own-do osseous surgery- open the flap then do osseous surgery then apically place the flap NOT indicated for periodontal regeneration therapy If you have minimal KG, you can do a full thickness flap (instead of inverse bevel) beyond the MGJ and try to suture the tissue down--or.
Gingival flap procedure, including root planing – one to three contiguous teeth or tooth bounded spaces per quadrant D4245 Apically positioned flap D4249 Clinical crown lengthening – hard tissue D4260 Osseous surgery (including flap entry and closure) – four or more contiguous teeth or tooth bounded spaces per quadrant D4261.
Methods of exposing impacted teeth in order to bring them into the line of the arch include gingivectomy, the apically repositioned flap and closed eruption techniques. These procedures aim to facilitate the eruption of the impacted tooth with a minimum of disruption or damage to the tooth itself or adjacent structures.
Mechanical tooth-brushing was reinstated one week after the surgery. The impacted tooth was cleaned and scaled to permit bonding. An orthodontic bracket or button was bonded to position [Figure 6]. After three weeks, the surgical site had revealed an adequate width of keratinized gingiva.

Simultaneously-impacted mandibular 2 nd and 3 rd molar teeth are uncommon in clinical practice. With respect to management; the main question is which tooth should be removed (the 2 nd molar.
Uncovering Labially Impacted Teeth The purpose of this study was to examine the esthetic and periodontal differences between two methods of uncovering labially impacted maxillary anterior teeth: the apically positioned flap and closed-eruption techniques.
They emphasize the importance of maintaining the integrity of the dental follicle of permanent teeth while removing supernumeraries. The doctors describe four methods for uncovering impacted maxillary central incisors: gingivectomy, apically positioned flap, the closed eruption technique, and surgical replantation.
- Apically positioned - Replaced flap. Mucoperiosteal. full thickness. Mucosal. partial thickness. Proximity of the ascending ramus to the terminal tooth Presence of impacted or partially impacted third molars. Factors exaggerating the periodontal (bony) lesion in the tuberosity area Management of soft tissue pockets on terminal teeth.A gingival graft, also called gum graft or periodontal plastic surgery, is a generic name for any of a number of periodontal surgical procedures in which the gum tissue is grafted.The aim may be to cover exposed root surfaces or merely to augment the band of keratinized tissue.
The apically positioned flap is a commonly used surgical approach, and is important for maintaining an adequate zone of keratinized tissue. With regards to implants, many studies suggest that the presence of healthy peri-implant soft-tissue plays an important role in long-term success of dental implants (see studies below).
• If crown is positioned mesially and over the root of the lateral incisor, the crown should be exposed completely with an apically positioned flap. 36. PALATAL IMPACTION OF UPPER CANINE CLOSED ERUPTION • Crown is surgically exposed, an attachment is bonded during the exposure, flap is sutured back, leaving a twisted ligature wire passing.
sure), apically positioned flap and closed exposure. Any of the afore-mentioned three techniques may be used for labially impacted teeth, because there is lit-tle or no bone over the crown of the impacted canine. However, for teeth impacted in the center of the al-veolus, an excisional approach (open exposure).

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. Both full-thickness and partial-thickness flaps can also be displaced.Labially impacted maxillary teeth uncovered with an apically positioned flap technique have more unaesthetic sequelae, such as increased clinical crown length, decreased width of attached tissue, gingival scarring, and intrusive relapse than those uncovered with the closed-eruption technique.[1,2] Various procedures have been utilized.
Methods of exposing impacted teeth in order to bring them into the line of the arch include gingivectomy, the apically repositioned flap and closed eruption techniques. These procedures aim to facilitate the eruption of the impacted tooth with a minimum of disruption or damage to the tooth itself or adjacent structures. The aim of this paper is to discuss the various surgical methods.
preferred if the impacted tooth is low down in the alveolus and bucco lingually close to its place in the arch. For palatally positioned tooth where there is presence of thick palatal mucosa tissue the window technique usually requires placement of a periodontal pack to prevent regrowth of tissue over the exposed tooth. -Vertical position.
surgical intervention approach. Based on the position of the impacted canine, it can be treated with an open or closed technique [28].Labial impactions are usually treated by an open surgical intervention such as gingivectomy or apically positioned flap depending on the impacted tooth position [2,28]. Palatal impactions are generally.
and (3) Apically repositioned flap technique. Window technique This represents the simplest form of open exposure. It entails the surgical removal of the mucosa and bone immediately overlying the impacted tooth.3,4 It is the most direct way of exposing an impacted canine that is located and usually palpable immediately under the surface.
Uncovering labially impacted teeth: apically positioned flap and closed-eruption techniques. Angle Orthod. 1995;65(1):23-32; discussion 33. The purpose of this study was to examine the esthetic and periodontal differences between two methods of uncovering labially impacted maxillary anterior teeth: the apically positioned flap and closed.
Surgical technique for exposure of bucally impacted teeth by means of an apically positioned flap, previ-ously described in the literature (1,7,8), was carried out by making two parallel or slightly apically diverging vertical incisions, mesial and distal to the tooth to be exposed, preserving the papillae of the adjacent teeth.
Tooth impaction in the maxillary anterior region is a common dental anomaly. Genetic and local factors are associated with the etiology. 1,2 Previous studies 3,4 have shown that when there is an impacted central incisor, the ipsilateral lateral incisor root is displaced about 5 mm distally compared with the contralateral lateral incisor's normally positioned.
The apically repositioned flap is an alternative way of performing an open exposure technique on the buccal side. It is aimed at improving the periodontal outcome by ensuring that attached gingiva covers the labial aspect of the erupted tooth in the final instance. For a buccally impacted tooth, a surgical flap is raised from the attached.

The apically repositioned flap is a quick, simple and reliable method for exposing most teeth that are impacted labially or within the line of the arch. It is suitable for tooth exposure in both children and adults and will help to minimize potential problems. However, its use is limited if the tooth is positioned.
Impaction of maxillary and mandibular canines is a frequently encountered clinical problem, the treatment of which usually requires an interdisciplinary approach. Surgical exposure of the impacted tooth and the complex orthodontic mechanisms that are applied to align the tooth.Labially impacted maxillary teeth uncovered with an apically positioned flap technique have more unaesthetic sequelae, such as increased clinical crown length, decreased width of attached tissue, gingival scarring, and intrusive relapse than those uncovered with the closed-eruption technique [1,2].
Apically positioned flap (D4245) Procedure is used to preserve keratinized gingiva in conjunction with osseous resection and second stage implant procedure. Procedure may also be used to preserve keratinized/attached gingiva during surgical exposure of labially impacted teeth, and may be used during treatment of peri-implantitis.

on of the impacted teeth (Figure 3). The position of impacted mandibular canines did not im-pose any restrictions on the selection of the surgical treatment method. Given that the upper jaw was undergoing the surgical procedure involving the apically positioned flap technique, for the sake of an easier postoperative recovery and patient.
The apically positioned flap is a commonly used surgical approach to achieve pocket elimination. This technique is important for maintaining an adequate zone of keratinized tissue, as opposed to the gingivectomy technique, where soft tissue is resected. Dr. Adam Bear discusses the advantages this procedure has for surgical crown-lengthening procedures.

The doctors describe four methods for uncovering impacted maxillary central incisors: gingivectomy, apically positioned flap, the closed eruption technique, and surgical replantation.
Photographic examination revealed vertical relapse of the uncovered teeth in the APF group. We conclude that labially impacted maxillary anterior teeth uncovered with an apically positioned flap technique have more unesthetic sequalae than those uncovered with a closed-eruption technique.
To be able to use an apically displaced flap for canine exposure the tip of the crown of the impacted canine must be near the mucogingival line of the lateral incisor. To ensure a satisfactory esthetic result, the gingival displacement should not exceed a few millimeters. If the tooth is impacted in a higher position, a replaced flap should.
In situations where the labially impacted tooth is positioned very high within the buccal sulcus, near to the nasal spine or deep within the alveolus, an apically repositioned flap may be difficult to use. 6 In these clinical situations the surgical method of choice is the closed eruption The Apically Repositioned Flap in Tooth Exposure.
An Impacted tooth: A disorder in which a tooth is so crowded in its socket that it cannot erupt normally. An impacted tooth is any tooth that is prevented from. reaching its normal position in the mouth by tissue, bone, or another tooth. An impacted tooth is a tooth that is all the way or. partially below the gum line and is not able to erupt.
