Evaluating Posterior Edentulous Mandible Alveolar Crest Dimensions By Cone Beam Computed Tomography

INTRODUCTION: In this study, alveolar crest height (CH) and width (CW) in patients with edentulous mandible were measured, also the impact of gender and age factors on obtained values were evaluated.
METHODS: Cone beam computed tomography (CBCT) images of 39 males and 38 females were analyzed retrospectively. CH and CW at 10 mm distal of right mental foramen of patients were measured on sectional images. Independent sample T-test and One-way ANOVA test were used for statistical analysis.
RESULTS: In CH measurements, there was no significant difference between males and females (p= 0.058). However, males had significantly higher CW values compared to females (p=0.039). Considering age criteria, it was understood that age of patient have no significant effect on CW (p=0.586) and CH (p=0.465).
DISCUSSION AND CONCLUSION: In this study, males just had significantly higher CW values. Besides, age factor had no significant effect on crest dimensions and it was concluded that each patient should be evaluated in itself during dental implant replacement regardless of age and gender.
