Mandibular interior teeth

mandibular interior teeth

The mandibular incisors and canines are similar in shape, with the incisors being shorter and slightly thinner and the canine roots being longer and somewhat heavier. The incisor roots are more likely to be fractured, because they are somewhat thin and therefore should be removed only after adequate preextraction luxation. The alveolar bone that overlies the incisors and canines is quite thin on the labial and lingual sides. The bone over the canine may be somewhat thicker, especially on the lingual side.

The lower universal (no. 151) forceps are usually used  to remove these teeth. Alternative choices include the no. 151A or the English style of Ashe forceps. The forceps beaks are positioned on the teeth and seated apically with strong force. The extraction movements are generally in the labial and lingual directions, with equal pressures both ways. Once the tooth has become luxated and mobile, rotational movement may be used to expand the alveolar bone further. The tooth is removed from the socket with tractional forces in a labial incisal direction (Fig. 7-67).
