Evaluation of dental implant placement site in anterior maxilla

Abstract

Background: Successful implant treatment depends on precise planning. Information on the height, width, morphology, and density of alveolar bone surrounding the proposed implant site is very critical for determination of the size of the implant and angle of placement. The present study was conducted to assess anterior maxilla for dental implant placement. Materials & Methods: 45 patients of both genders requiring dental implant in maxillary anterior teeth underwent CBCT scan of anterior maxilla was done with Planmica CBCT machine. Parameters such as bone height, bone width, buccal undercut location and buccal undercut depth was measured. Results: The mean bone height in central incisor region was 18.26 mm, in lateral incisor region was 18.02 mm and in canine region was 23.14 mm. The mean bone width in central incisor region was 9.30 mm, in lateral incisor was 8.45 mm and in canine region was 9.81 mm. The mean buccal undercut location at central incisor was 5.72 mm, at lateral incisor was 3.42 mm and at canine was 5.14 mm. Buccal undercut depth at central incisor was 0.72 mm, at lateral incisor was 0.80 mm and at canine region was 0.71 mm. The difference was significant (P
