Summary
Piezosurgery significantly reduces pain, swelling, and improves mouth opening after lower third molar extraction compared to traditional rotary instruments. This advanced technique enhances patient recovery, despite longer surgical times.
Area of Science:
- Oral Surgery
- Dental Implantology
- Maxillofacial Surgery
Background:
- Impacted lower third molar extraction is a common surgical procedure.
- Complications such as pain, swelling, and trismus can occur post-operatively.
- Comparing surgical techniques is crucial for optimizing patient outcomes.
Purpose of the Study:
- To compare the efficacy of piezosurgery versus traditional rotary instruments for impacted lower third molar extraction.
- To evaluate postoperative outcomes including pain, edema, and trismus.
Main Methods:
- A prospective, randomized, non-blinded clinical study.
- 18 patients aged 18-40 years underwent bilateral lower third molar extractions.
- One side was treated with rotary instruments, the other with piezosurgery.
Main Results:
- Piezosurgery group showed significantly less pain and edema.
- Improved trismus recovery was observed in the piezosurgery group.
- Surgical time was longer with piezosurgery, but postoperative outcomes were more favorable.
Conclusions:
- Piezosurgery offers superior postoperative results for impacted lower third molar extraction.
- Reduced pain, swelling, and better mouth opening indicate enhanced patient recovery.
- Piezosurgery is a beneficial alternative to rotary instruments for this procedure.
