[The topographical anatomy of the incisor canal].

Abstract

In 254 skulls (22-70 years of age) with orthognathic intact occlusion in 66 maxillodental sawing topographic anatomy of the incisor canal has been studied by means of craniometric and statistical methods. In mature age the average length of the incisor canal and its openings possess certain statistically significant age and sex differences. The incisor canal is situated near the tops of the central incisors roots at the distance of 7.40 +/- 0.11 mm. The incisor opening, independently on the sex, is situated on the inferior surface of the palatile process of the median line at the distance of 9.81 +/- 0.21 mm from the point formed by the medial angles of the crowns of the upper central incisors. In mature age the distance between the incisor opening and the central incisors roots is 3.51 +/- 0.10 mm.
