Abstract
Aim. To assess the anatomical dimensions of buccal bone thickness of maxillary and mandibular canines for immediate dental implant procedure using CBCT in Saudi population. Materials and methods. This cross-sectional study was conducted at Riyadh Elm University, Riyadh, Saudi Arabia. A total of 150 CBCT images of buccal bone thickness were assessed. The age of the subjects was between 18-60 years. All scans were taken by trained technicians using GALILEOS Comfort Plus (Sirona Dental Systems, Inc.). For each maxillary canine analyzed, measurement of the facial wall thickness was recorded at three points, coronal third of the root (thickest part of the bone within 3 mm from the bony crest), middle third of the root and apical third of the root. All measurements were statistically analyzed using SPSS. Results and discussion. Statistically, the mean value of apical thickness was significantly higher (mean: 0.96) compared to both mid (mean: 0.84) and coronal (mean: 0.83) values. Among males, apical bone thickness showed a statistically significant difference compared to both coronal and mid ones. Similarly, in females, apical bone thickness was statistically significantly higher compared to both coronal and mid ones. The mean value of apical bones thickness was statistically significantly higher, compared to mid and coronal level, in the younger age group (less than 30 years). However, in older age groups (30-49 years and above), no statistically significant differences were found between coronal, mid and apical bone thickness. Conclusions. The present study evidenced significant differences in bone thickness among the apical, mid and coronal leve, but no difference between males and females. The younger age group showed significantly higher apical bone thickness. However, no difference in bone thickness was seen in older age group.
