A new surgical technique preserves bone during impacted wisdom tooth extraction. This method, using piezoelectric surgery, shows potential for better bone preservation, though it may increase ibuprofen use post-surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Research
- Surgical Innovation
Background:
- Impacted upper third molars (BIUTMs) often require surgical extraction.
- Traditional extraction methods can involve bone removal, potentially impacting the maxillary tuberosity.
- Minimally invasive techniques are sought to improve surgical outcomes.
Purpose of the Study:
- To introduce and evaluate a novel maxillary tuberosity bony mucoperiosteal flap technique for BIUTMs extraction.
- To compare bone preservation and postoperative outcomes between the novel technique and conventional extraction.
Main Methods:
- A prospective study involving 28 BIUTMs in 24 patients, randomly assigned to experimental (bone preservation with piezoelectric surgery) and control (conventional bone removal) groups.
- Evaluation of surgical duration, postoperative complications (swelling, trismus, pain via VAS and ibuprofen consumption), infection, and sinus perforation.
Main Results:
- The experimental group showed significantly higher total ibuprofen consumption (P = 0.009).
- Surgical duration was marginally longer in the experimental group (P = 0.075), but no significant differences were found in postoperative pain, swelling, or trismus.
- No intraoperative sinus perforations or postoperative infections occurred in either group.
Conclusions:
- The novel bony mucoperiosteal flap technique offers a potential approach for BIUTMs extraction with bone preservation.
- Further long-term follow-up is required to confirm the sustained benefits of this bone-preserving method.
