Analysis of the Anterior Maxillary Facial Bone Wall Dimensions on Cone-Beam Computed Tomography Images
Objectives: The purpose of this study was to analyze the thickness of the facial bone wall at teeth in the anterior maxilla based on cone-beam computed tomography (CBCT) images.
Methods: Standardized CBCT images were conducted in 156 patients (78 males and 78 females), aged between 18 to 56 years old. The distance from the cementoenamel junction (CEJ) to the facial bone crest was determined. The thickness of the facial bone wall in the respective sagittal scans was measured perpendicular to the long axis of the tooth at two locations: P1 (4mm apical to the cementoenamel junction) and P2 (at the middle of the root).
Results: The distance between CEJ and FBC increased with age. At position P1 and P2, all examined teeth exhibited a thin facial bone wall (<2 mm). There was no significant difference between age groups or between genders. However, there was a statistically significant difference between the values of right and left sides. Most of the teeth had a bone wall thickness varied between 0.5 and 1 mm, no case had the thickness of 2 mm.
Conclusions: The facial bone wall in most maxillary anterior teeth was mostly thin. CBCT analyses of the facial bone wall and the sagittal angle are recommended to ensure the most appropriate of immediate dental implant treatment approach.
