Comparative Morphometry of the Bone Structure in the Dentoalveolar Segments of Maxillary Incisors and Canines

摘要

We examined morphometric parameters of the bone tissue of 168 dentoalveolar segments that include maxillary incisors and canines regarding vertical midline. The area of dentoalveolar medial incisor segments was 1.81 +/- 0.14 cm(2); it did not differ significantly from the area of lateral incisor segments. The area of dentoalveolar segments including canines exceeded the corresponding figures in incisor segments. The thickness of the compact bone on the vestibular surface significantly increased from the cervical portion of the segment towards its base. The maximum thickness of the spongy bone on the vestibular surface was recorded in the apical part of canines dentition segments; the minimum thickness, in the middle portion of the dentoalveolar segments of lateral incisors.
