Reconstruction of fractured canine teeth with cast metal crowns and pulpar pins

During the last few years a significant increase in the number of dogs with traumatic dental problems has been observed, particularly those with fractured canine teeth. In the period 1994-1998, 12 dogs of different breeds (German Shepherd, Dobermann, Pit Bull and Bull Terrier) were referred with complete fractures of a total of 34 canine teeth. After endodontic treatment, preparation of teeth and taking of dental imprints according to routine methods, the fractured teeth were reconstructed using moulded metal crowns and parapulpar pins. The length of the latter was 16-22 mm according to the depth of the pulpa channel. The metal crowns were fixed to the remaining tooth with chemopolymers. All reconstructed teeth were observed for 36 months. Complications occurred only in 2 teeth (new fractures and removal of crown). The method of reconstruction of fractured teeth with moulded metal crowns and pulpar pins is relatively easy to perform and can be done in two stages. Efficacy was about 96% and is found to be practical for application in veterinary dental practice in Bulgaria.
