Effect of Piezoelectric Surgery onPostoperative Complications in Third Molar Surgery

Revolution or Routine? Assessing the Postoperative Impact of Piezoelectric Surgery on Edema, Trismus, and Other Complications in Third Molar Extractions

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Edema amounts with Routine and Piezoelectric Surgery	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.	The edema measurements are made on the patient preoperatively and on the 2nd and 7th postoperative days.
Trismus amounts with Routine and Piezoelectric Surgery	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.	The trismus measurements are made on the patient preoperatively and on the 2nd and 7th postoperative days.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Wound healing, bleeding, infection, alveolitis, paresthesia, and temporomandibular joint pain with Routine and Piezoelectric Surgery	These complications are recorded by clinical examination.	within 7 days after surgery
