Why it matters for dental

Endodontists and surgical specialists now have RCT-level evidence that a trephine-bur guided microsurgery technique can safely and predictably treat teeth in high-risk anatomical zones (mental foramen, palatal root proximity), potentially expanding the pool of teeth that can be saved instead of extracted.

Key points

  • Randomized controlled trial design provides the first head-to-head data comparing guided trephine-bur osteotomy vs. traditional freehand microsurgery in posterior maxillary/mandibular teeth.
  • Primary outcome metrics included radiographic healing at 12 months and intraoperative preservation of critical structures (nerves, sinus floor); both favored the guided cohort.
  • Technique reduces osteotomy size by ~40 % and shortens operative time by an average 18 minutes, with direct implications for chair-time fees and patient recovery.
  • Specialists considering investment in 3-D printed surgical guides or dynamic navigation should factor this new clinical evidence into ROI calculations.
