Statement of the Problem: The thickness and height of the facial wall of the alveolar bone in anterior part of maxilla is a critical factor to achieving esthetic and success of   implant insertion. Objectives:The aim of  present study was evaluating the anterior maxillary bone by cone beam computed tomography (CBCT) images.Methods :In this in vitro study, 200 CBCT images of the anterior maxillary teeth were examined. Each tooth was classified according to the sagittal root position and the measurements were done by one practitioner. Results:The following variables were significantly associated with gender (male predilection): tooth-ridge angulation (TRA )in the right lateral teeth; concavity angulation (CA)in the right central and lateral teeth; concavity depth (CD ) in the right lateral teeth and both canines; concavity location (CL)in the right canine; buccal bone height (BH)and palatal bone height ( PH) in the left canine.Age was associated with CLand ridge angulation in none of the teeth; with TRA and CD in all anterior teeth; bone density in the right lateral teeth; with CA in both  lateral teeth; with BH in both central teeth; with PHin the right central and left lateral teeth; and with TA in both lateral teeth and canines.
