Area of Science:

  • Oral and Maxillofacial Surgery
  • Surgical Techniques
  • Dental Implantology

Background:

  • Piezosurgery is increasingly utilized in oral and maxillofacial surgery.
  • A systematic description of piezosurgery osteotomy methods for complex mandibular third molar extraction is lacking.

Purpose of the Study:

  • To introduce four distinct osteotomy methods using piezosurgery for complicated mandibular third molar removal.
  • To evaluate the efficacy and outcomes of these piezosurgery techniques.

Main Methods:

  • A retrospective analysis of 55 patients undergoing extraction of 74 complicated impacted mandibular third molars.
  • Four piezosurgery osteotomy techniques were applied based on impaction type: complete bone removal, segmental bone removal, bone removal with tooth splitting, and block bone removal.
  • Outcomes assessed included success rate, operative time, and major complications.

Main Results:

  • All 74 impacted mandibular third molars were successfully extracted.
  • Average surgical time was 15 minutes.
  • A low complication rate of 2.7% (postoperative infections) was observed, with rapid recovery.

Conclusions:

  • The four described piezosurgery osteotomy methods are effective for managing complicated impacted mandibular third molars.
  • These techniques offer a safe and efficient approach to extraction in oral surgery.
