Abstract
Back ground and Aim: The placement of mini-implants in the posterior maxilla requires accurate assessment of interradicular distances to ensure stability and avoid complications. The purpose of this study was to evaluate the interradicular distance in the posterior maxilla of Persian adults with class I, II and III sagittal skeletal patterns using cone beam computed tomography (CBCT), aiming to identify the optimal site for mini-implant insertion in this region.
Materials and Methods: This cross-sectional study was conducted on CBCT images of 90 individuals aged 18-50 years to measure the interradicular spaces at 2, 4, 6 and 8 mm from the cementoenamel junction (CEJ) from the distal of the canine to the mesial of second molar in maxilla. The participants were divided equally among three sagittal skeletal classes. Data were analyzed by ANOVA and Tukey’s post hoc test (alpha = 0.05).
Results: The results demonstrated that the interradicular spaces gradually increase from the CEJ toward the apex. The widest interradicular distances were observed between the first and second premolars, particularly at 6 and 8 mm from the CEJ in all skeletal classes. There was a significant difference in interradicular distances based on skeletal patterns. Gender differences were minimal but statistically significant in specific regions. Age differences were not significant within the limits of this study.
Conclusion: Based on the findings of this study, while individual differences should be taken into consideration, the region between the first and second premolars at 8 mm from the CEJ seems to be the most favorable site for mini-implant insertion in the posterior maxilla in all sagittal skeletal patterns. |
