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 The normal path through which maxillary canines erupt may be altered due to changes in the eruption sequence in the maxilla, and also by space limitations due to crowding. For tooth exposure, a trapezoidal (3 sided) flap is used. Acta Odontol Scand. This chapter elaborates on canine impaction, keeping in mind the basic principles mentioned in the chapter on third molar impactions. Bone around the area is removed with bur, taking care to protect the roots of the adjacent teeth from damage. Review. Accordingly, if the impacted canine is located buccally, the crown of the tooth moves mesially. Assessment of the existing dentition is crucial to treatment planning e.g. permanent molar in three groups: RME combined with headgear (group 1), headgear alone (group 2) and untreated control group. Periodontal health of orthodontically extruded impacted teeth: a split-mouth, long-term clinical evaluation. If there is any resistance during elevation, the tooth must be sectioned, so that the fragments can be removed easily. panoramic and periapical) to a gold standard (histological examination of extracted primary canines after taking the radiographs). - This technique can also be performed with differing vertical angulations (vertical parallax). (a) Impacted maxillary canine. PDCs in group B that had improved in improve and should be referred to orthodontist without extracting primary canines to start comprehensive treatment with fixed appliances (Figures 6,7). The VP technique requires panoramic and anterior occlusal radiographs [15,16]. The patient must not have associated medical problems. This technique may be used in cases where there is enough space for the canine to erupt, and where the root formation is incomplete. The bone in the mandibular canine region consists of a thick lingual cortex and a thin buccal cortex. The smaller the alpha angle, checked between the age of 9 to 11 years old. J Periodontol. In situations where there is bilateral canine impaction and both teeth are close to the midline, the incision should always extend between the first or second premolars of both sides (Fig. mesial or distal movements of the x-ray beams will lead to a change of canine sector position as what happens in horizontal parallax techniques. the root length on the least and the most resorbed sides.

Kuftinec [12, 13] asserts that if the canines cusp is mesially at the root of the lateral incisor, the impaction is probably palatal but if the cuspid is found overlapping the distal half, a labial impaction is more probable. Orthodontic considerations in the treatment of maxillary impacted canines. In the 1980s, the extraction of deciduous primary canines as an interceptive treatment for ectopically positioned canines has been recommended. If the beam angle moves mesially, then the image of the impacted canine moves mesially too. Dental development stages are important for choosing the right time to start digital palpation.
