Summary
This study introduces a novel piezosurgery technique for mesiodens extraction using a vascularized bone flap. Computer-aided design surgical guides significantly reduced operative time compared to free-hand procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Surgical Innovation
Background:
- Mesiodens, the most common supernumerary tooth, can cause various dental and facial complications.
- Surgical extraction is the standard treatment, but traditional methods may pose risks to adjacent structures.
- Minimally invasive techniques are sought to improve surgical outcomes and patient recovery.
Purpose of the Study:
- To introduce a novel technique for mesiodens extraction using a vascularized pedicled bone flap with piezosurgery.
- To compare the efficacy of computer-aided design (CAD) surgical guide templates versus free-hand operation in mesiodens extraction.
- To evaluate outcomes including success rate, operative time, and impact on facial structures.
Main Methods:
- A novel surgical approach involving a vascularized pedicled bone flap and piezosurgery was designed for mesiodens extraction.
- Eight patients were divided into two groups: Group I (4 patients) used CAD surgical guides, and Group II (4 patients) underwent free-hand surgery.
- Outcomes measured included operative time, success rate, anterior nasal spine (ANS) position, nasolabial angle (NLA) changes, and complications.
Main Results:
- All mesiodentes were successfully extracted in both groups with no major complications.
- Operative time was significantly shorter in the CAD surgical guide group (Group I) compared to the free-hand group (Group II).
- No significant differences were observed in preoperative and postoperative ANS position or NLA values between the groups.
Conclusions:
- CAD surgical guide templates enhance clinical accuracy and reduce operative time in mesiodens extraction.
- The described piezosurgery technique with a vascularized pedicled bone flap is a safe and effective method for mesiodens removal.
- This approach offers a promising alternative for precise and efficient surgical management of mesiodens.
