Effect of Piezoelectric Surgery onPostoperative Complications in Third Molar Surgery

The purpose of this study is to compare the effects of piezoelectric surgery on postoperative edema, trismus and other postoperative complications (Wound Healing, Bleeding, Infection, Alveolitis, Paresthesia) with conventional bur method applied in surgical extraction of impacted mandibular third molars.

The main question it aims to answer is:

Is piezoelectric surgery effective on reducing the edema, trismus and other postoperative complications (Wound Healing, Bleeding, Infection, Alveolitis, Paresthesia) in impacted third molar surgery? Postoperative edema measurements are determined at 24 hours, 48 hours, and 7 days using the flexible ruler method. Trismus is determined by measuring the interincisal distance. Statistical analyses are performed to compare the two surgical methods.

Treatment and study plan

conventional surgery

Procedure

This retrospective clinical study included 30 patients who underwent extraction of impacted lower third molars with conventional surgery

piezoelectric surgery

Procedure

Description: This retrospective clinical study included 30 patients who underwent extraction of impacted lower third molars with piezoelectric surgery

Primary outcomes

Edema amounts with Routine and Piezoelectric Surgery

Time frame: The edema measurements are made on the patient preoperatively and on the 2nd and 7th postoperative days.

Edema measurements are made on the distances between the corner of the eye and the angulus mandible, between the tragus and the corner of the mouth, and between the tragus and the soft tissue pogonium. These points were marked with a dermatological pen and measured with the flexible ruler method.
Trismus amounts with Routine and Piezoelectric Surgery

Time frame: The trismus measurements are made on the patient preoperatively and on the 2nd and 7th postoperative days.

In order to determine the trismus, the values of the mouth openings of the patients are obtained by measuring the distance between the mesial corners of the first permanent incisors in the upper and lower jaws with the help of a caliper (Mitutoyo Company, Japan) with a sensitivity of 0.05.

Secondary outcomes

Wound healing, bleeding, infection, alveolitis, paresthesia, and temporomandibular joint pain with Routine and Piezoelectric Surgery

Time frame: within 7 days after surgery

These complications are recorded by clinical examination.
