Exposure of labially impacted canine by surgical window technique, Closed eruption technique for labially impacted canine, (a, b) Schematic diagram of apically positioned flap for exposure of a labially positioned crown. For tooth exposure, a trapezoidal (3 sided) flap is used. involvement [6]. that is commonly done is to only digitally palpate the canine area without palpating high in the vestibule as much as possible. Impacted canines are one of the common problems encountered by the oral surgeon. The lower part of the incision must lie at least 0.5 cm away from the gingival margin. In cases of unilateral impaction, instead of extending the incision to the contralateral side, a vertical incision may be given in the mid palatal region. CBCT imaging has also been used more recently to evaluate position and associations of canines. Review. Small areas of resorption are not of interest for general dentists or orthodontists (grade 1 and 2) since those teeth have a good prognosis on the long term
Impacted canines may not be associated with any symptoms, and may be accidentally discovered during the routine radiographic examination, or during the investigation of other dental conditions.

If the impacted maxillary canine is in an unfavourable position, and cannot be brought into normal occlusion, it should be removed earlier rather than later. You can change these settings at any time. However, it is important to note that all cases in this study had a mild crowding and small space deficiency (< 4mm). Angle Orthod 81: 370-374. maxillary canine location than VP technique, however, both techniques were poor at localizing the buccal ectopic maxillary canine [17]. Any one of the following techniques may be employed depending on the depth and position of the impacted tooth: Creating a surgical window/Gingivectomy: This is done if the tooth lies just underneath the gingiva. Impacted mandibular canines are not as frequent as maxillary canines, and are usually found in a labial position. Rayne technique: This involves differing vertical angulations, with one periapical and one maxillary anterior occlusal radiograph being taken [7]. The apical third and palatal surface were commonly involved. Impacted tooth c.) Supernumery tooth:, Why may teeth become impacted? Alexander Katsnelson A, Flic WG, Susarla S, Tartakovsky JV, Miloro M. Use of panoramic X-ray to determine position of impacted maxillary canines. The impacted maxillary canine may be located in an intermediate position, with the root oriented labially and the crown palatally, or vice versa. Another alternative technique is to use a crevicular incision, expose palatally and place orthodontic brackets as shown in Fig. Fifty per cent of the resorptive lesions were mild, 20% moderate and 30% severe. The buccal object rule is a method for determining the relative location of objects hidden in the oral region. the SLOB rule and later confirmation by surgical exposure, there were 37 labially impacted canines, 26 palatally impacted canines, and 5 mid-alveolar impactions. On comparing the buccal object rule and panoramic localization techniques in these patients, it was found Chaushu et al. Presence of associated cyst, odontomas or supernumerary teeth. Note the close relationship of the root of the impacted canine to the floor of the maxillary sinus and nose. Gingivectomy may be done when it is possible to uncover at least one half to 2/3 of the crown, leaving at least 3 mm of gingival collar. development. Presence of impacted maxillary canines Management There are numerous management options for ectopic canines: 1) Interceptive extraction of deciduous canine This is only suitable if the permanent canine is minimally displaced It must be done before the age of 13, ideally before the age of 11 document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); BDS (Hons.) To decrease chances of hematoma formation, a prefabricated clear acrylic plate may be used to cover the palate post-operatively. Alpha angle (not similar to Kurol angle) of 103
Bone around the area is removed with bur, taking care to protect the roots of the adjacent teeth from damage. For example, the jaw may be too small to fit the wisdom teeth. (f) Using a blunt instrument placed in the socket of the tooth on the buccal side, pressure is exerted on the cut end of the crown (see black arrow) to push the crown palatally, (g) Empty socket on the palatal side after removal of the crown, (h) Flap is replaced back and suturing completed. 2. had significantly less improvement in impacted canine position after

the patients in this age group have either normally erupted or palpable canine. There was a significant difference between all the groups except between group 3 and 4 [11]. Teeth may also become twisted, tilted, or displaced as they try to emerge, resulting in impacted teeth. Computed Tomography readily provides excellent tissue contrast and eliminates blurring and overlapping of adjacent teeth [16]. The impacted canine is separated by a thin layer of the bone from the maxillary sinus and nasal cavity (Fig. Different Types of Radiographs
Later on, this can lead to periodontal problems. in 2017 opined that the most common treatment strategies for the treatment of mandibular canine impactions are surgical extraction and orthodontic traction. These include retained primary teeth, proclination/displacement of adjacent incisors or clinical features associated with cyst formation.

If the canine bulge was not palpable, the palatal area also should be palpated to ensure that the canine bulge is not at the palatal area, which indicates
It is held in close contact with the palatal bone by pressing a gauze pack with the dorsum of the tongue, for an hour or two. than two years. The SLOB rule means "Same Lingual, Opposite Buccal". Dent Clin North Am 52: 707-730. MFDS RCPS (Glasg.) 2008;105:918. when followed for periods more than 10 years if the PDCs are moved away. The area is overcrowded and there's no room for the teeth to emerge. diagnoses of impacted maxillary canines, as well as the interceptive treatment (including Going into the fine details of localization of canine is beyond the purview of this chapter. (a) Impacted maxillary canine. This will make any object that is buccal/facial of the teeth automatically farther from the film/sensor. Field HJ, Ackerman AA. (af): Schematic diagram showing surgical removal of labially impacted maxillary canine. About 50% of maxillary incisors adjacent to PDC show root resorption [35]. This method may pose a risk of haemorrhage from the nasopalatine vessels which can, however, be controlled by pressure pack or by electrocautery. Nevertheless,

Showing Incisors Root Resorption. Position of the impacted canine, number, location, and amount of resorptions on . The authors conducted a literature review regarding the clinical and radiographic In this review, diagnosis and interceptive treatment of PDC will be focused on and explained according to the latest evidence. It must be noted that these teeth retain their original innervation, which is important to consider while administering local anaesthesia. The chosen method would depend on the degree of impaction, age of the patient, stage of root formation, presence of any associated pathology, dental condition of the adjacent teeth, position of the tooth, patients willingness to undergo orthodontic treatment, available facilities for specialized treatment and patients general physical condition. Maxillary incisor root resorption in relation to the ectopic canine: a review of 26 patients. In the same direction i.e. The clinical signs that implicate an impacted maxillary canine include: 1.Delayed eruption of the permanent canine or prolonged retention of the primary canine.' 2.Absence of a normal labial canine bulge in the canine region.2 3.Delayed eruption, distal tipping, or migration of the permanent lateral incisor.3 PDC in sector 1,2 have the best prognosis and spontaneous eruption after extracting maxillary primary canines with

Parallax refers to the apparent movement of an object based on the position of the beam. (a) Flap outlined from the second premolar on one side to the second premolar of the opposite side, (b) Following reflection of the mucoperiosteal flap, multiple drill holes are placed in the bone overlying the crown. To prevent soft tissue regrowth over the exposed crown, a pack (such as a perio pack or roller gauze impregnated with iodoform or antibiotics) may be inserted or sutured in place. Although the exact cause of impacted maxillary canines remains unknown, multiple factors may play a role. Follow-up should be started 6 months after extracting primary canines by digital palpation at PDC area and taking a new panoramic radiograph. Patients in group 1 had 85.7% successful canine eruption, 82% in group 2 and 36% in the untreated control group [10]. As in the case of maxillary canine in the labial position, bone removal is done with bur. Chapokas et al. Angle Orthod 81: 800-806. Limited space for eruption as the canines erupt between teeth which are already in occlusion. The occlusal film below shows that the impacted canine is lingually positioned. CBCT or CT scan is very useful to locate the exact position of such a tooth. Angle Orthod 84: 3-10. Am J Orthod Dentofacial Orthop 126: 397-409. degrees indicates need for surgical exposure (Figure

Southall and Gravely technique: One maxillary anterior occlusal radiograph and one maxillary lateral occlusal radiograph are taken [6]. a half following extraction of primary canines. The SLOB (same-lingual, opposite-buccal) rule is similar to image shift but the film/sensor must be positioned to the lingual of the teeth to use this method. Interceptive Treatment a Review and Decision Trees J Orthod Craniofac Res 1: 106. Canine position is much important in denture teeth Three radiographic methods were compared (CBCT,
of the cases at this age, surgical exposure followed by orthodontic traction of the canines is indicated [2,12]. Secondary reasons include febrile diseases, endocrine disturbances and Vitamin D deficiency. Once the crown is moved out, it may be grasped using an upper anterior or premolar forceps. Lack of a bulge on the labial side of the alveolus in the canine region.
