Overview

Retrospective study assesses optimal MI placement in the mandibular buccal shelf for Portuguese individuals, suggesting favourable sites.

Key Points

  • Determine the best micro-implant insertion site along the mandibular buccal shelf using cone beam computed tomography.
  • Retrospective analysis of CBCT scans from 90 Portuguese patients aged 14 to 40
  • Assessment of paired mandibular buccal shelf sites
  • Comparative and correlation analyses performed at p < 0.05
  • Significant increase in mandibular buccal shelf width from mesial to distal (p < 0.001)
  • Decreased MBS steepness and cortical bone thickness from mesial to distal (p < 0.001)
  • Negative correlation between age and cortical bone thickness near distobuccal cusp (r ≤ -0.373, p ≤ 0.007)
  • Asymmetric differences in MBS steepness and cortical bone thickness noted between right and left sides (p ≤ 0.016)
