Restorative alternatives for the treatment of an impacted canine: surgical and prosthetic considerations. As a conclusion, PDCs in sector 1, 2, and 3 most probably will benefit from extracting maxillary primary canines, while PDCs in sector 4 and 5 will not palatal eruption that needs orthodontic intervention. 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. The mentioned consequences could be avoided in most of the cases with early Related data were Note the relationship of the cuspid to the roots of the adjacent teeth, nasal cavity and maxillary sinus. Two RCTs investigated the space loss after extraction of primary maxillary canines [10,12].

Summary An intraoral technique for object localization is the tube-shift method. The SLOB (Same Lingual - Opposite Buccal) rule helps to remind the dental operator that when the tube head is shifted mesially, the lingual or palatal root will also be shifted mesially (in the same direction as the shifted tube head) on the developed film and the buccal or mesiobuccal root will be shifted distally (in the opposite direction .
