Abstract
|
|
|
Purpose : Anterior region is crucial area for esthetic implant restoration. However, the alveolar process undergoes atrophy after removal of teeth and creates unfavorable situation for implant installation. The knowledge of the thickness of alveolar bone is required to estimate and expect the bone resorption after extraction. The aim of this study is to measure facial, palatal and faciopalatal bone thickness on maxillary anterior teeth.
Methods : Facial, palatal, and faciopalatal bone thickness were measured on the computed tomography (CT) images from 57 patients, using an image analyzer program (Ondemand 3Dⓡ, Cybermed, Seoul, Korea).
Results: The thickness of facial bone in incisors, lateral incisors and canines were less than 1㎜. The thickness of facial bone increased from anterior to posterior region and the thickness of palatal bone increased from posterior to anterior region.
Conclusion : The measurement can be used for planning implant surgery before extraction. CT has are clinically useful in the evaluation of thickness of alveolar bone.
