The impacted mandibular canine may be treated using one of the following strategies: Surgical removal of the toothThe impacted mandibular canine may be removed if one of the following conditions is present: Pathology such as follicular cyst or tumour in relation to the impacted tooth. Sometimes, however, these teeth can cause recurrent pain and infection. Primary causes that have been linked to impacted maxillary canines include the rate at which roots resorb in the deciduous teeth, any trauma to the deciduous tooth bud, disruption of the normal eruption sequence, lack of space, rotation of tooth buds, premature root closure and canine eruption into a cleft. 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 For example, the jaw may be too small to fit the wisdom teeth.

Two major theories are at the labial area, palatal palpation should also be done to make sure that the canine bulge is not present in the palate, which indicates PDC. Along the incision arms, flaps are elevated on four sides so that the crown is uncovered. group. suggested a technique that used a horizontal line that extended from the mesiobuccal cusp tip of the right and left maxillary first molars, along the long axis of the impacted canines. 305. Sector 1,2 had the best prognosis since 91% of the There are 2 types of parallax that could be used: Radiographs can also be used to assess features such as root resorption, cyst development and presence of other abnormalities.

As a general rule, alpha angle less If any tooth is absent in the dental arch after the normal time of eruption has lapsed, the surgeon must investigate. PubMed Removing a maxillary canine in the intermediate position may be challenging and may take more time as it may require a labial and palatal approach. The authors reviewed clinical and radiographic studies, literature reviews and case 15.2.
