Overview

Imaging study reveals that larger preoperative cleft dimensions predict poorer bone bridge outcomes in secondary alveolar bone grafting, indicating earlier intervention improves bone healing.

Key Points

  • To identify preoperative 3D morphological predictors of postoperative bone bridge formation in secondary alveolar bone grafting using CBCT and determine optimal surgical timing.
  • Evaluated 100 patients undergoing secondary alveolar bone grafting with preoperative and 6-month postoperative CBCT scans.
  • Categorized patients across three surgical stages (lateral incisor eruption, canine eruption, and multi-bracket treatment) and measured 3D cleft dimensions alongside postoperative bone bridge parameters.
  • Conducted multiple linear regression analysis to determine independent morphological predictors of surgical success.
  • Larger preoperative cleft volume (p < 0.001) and larger apical cleft area (p = 0.019) independently predicted decreased postoperative mesial bone bridge thickness.
  • Wider preoperative cleft at the midportion strongly predicted decreased bone bridge height (p = 0.001).
  • Stage 3 patients had significantly larger preoperative cleft volumes, resulting in significantly larger postoperative residual bone defects compared to earlier stages.
