IS THERE A RELATION BETWEEN ALVEOLAR RIDGE DIMENSIONS AND BUCCAL UNDERCUT IN THE ANTERIOR MAXILLA?≠

Abstract

Aim: The aim of this study was to investigate of the relation between the alveolar ridge dimensions and buccal undercut in the anterior maxilla.Material and Methods:Cone-beam computed tomography images of 150 patients (97 females, 53 males), aged between 16-40 years having full anterior dentition at the maxilla were evaluated. Six-hundred cross-sectional images were obtained from the regions between central, lateral and canine teeth in the right and left maxilla. The alveolar height and width, and the presence and depth of buccal undercut in these regions were assessed. Results:It was found that the prevalence of buccal undercuts in different regions ranged from 74% to 84% on average. Comparedto males, the presence of buccal undercut was found to be significantly higher in females in the regions of between right lateral-canine teeth, left central-lateral teeth and left lateral-canine teeth (p
