Abstract
Aim: To compare palatal bone thickness in various median and paramedian regions and palatal cortical plate thickness in inter-radicular spaces for suitable micro-implant placement between adolescents and adults, in both the genders using Cone Beam Computed Tomography (CBCT). Materials and Methods: CBCT scans of 100 patients were selected and divided into 4 groups: Group 1A: 25 Adolescent male (11 to 17 years), Group 1B: 25 Adult female (11 to 17 years), Group 2A: 25 Adolescent male (21 to 30 years), Group 2B: 25 Adult female (21 to 30 years). Palatal bone thickness was measured at 28 sites and Palatal cortical plate thickness were measured at 12 sites by using InVivo Dental 5.0 software. The bony thickness was compared between the two groups (adults and adolescents) for differences using unpaired ‘t’ – test. To evaluate the effect of gender on the bone thickness in adults and adolescents was analyzed using analysis of covariance (ANCOVA) with age group as a factor and gender as a covariate. Adjusted means for bone thickness was estimated for adults and adolescents. All testing was done using two-sided tests at alpha 0.05. Results: Palatal bone thickness in the adults (P<0.05) were significantly higher than those in the adolescents. Anterior palate had maximum thickness in all the groups. Gender comparison revealed that males had greater palatal; bone thickness than their male counterparts. No significant (P>0.05) difference was found for cortical plate thickness at inter-radicular sites between adults and adolescents. Palatal cortical plate thickness was maximum between fist molar and second molar. Conclusion: Bone thickness of the palate differs greatly depending on the measurement sites. Also individual variations were great. Palate constitutes a site of choice for insertion of micro-implant for anchorage reinforcement in orthodontic treatment.
