Abstract

Objectives: Tomeasure the thickness of facial bone wall and facial gingiva at teeth in the anterior maxilla based on CBCT of 100 patients. Methods:this descriptive cross-sectional study was realized on 100 CBCT fulfilling all inclusion criteria. The thickness of facial bone wall at teeth in the anterior maxilla was measured in the sagittal sectionat 1mm from crestal level (point A), 3mm from crestal level (point B), 5mm from crestal level and at the apex. The thickness of facial gingival was measuredonly at point A. Results: the thickness of facial bone wall (in mm) of central incisor: at point A is 0,76 ± 0,24, at point B is 0,69 ± 0,23, at point C is 0,60 ± 0,24, at the apex is 1,63 ± 0,93; of lateral incisor: at point A is 0,79 ± 0,29, at point B is 0,61 ± 0,44, at point C is 0,27 ± 0,31, at the apex is 1,77 ± 0,94; of canine: at point A is 0,83 ± 0,39, at point B is 0,71 ± 0,46, at point C is 0,42 ± 0,34, at the apex is 1,60 ± 0,79. The thickness of facial gingiva at point A: of central incisor is 0,76 ± 0,19; of lateral incisor is 0,59 ± 0,19; of canine is 0,53 ± 0,19. Conclusion: most of the patients present the facial bone plate and facial gingiva inferior of 1mm.
