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.

Inclusion Criteria:

• Patients with mesioangular, distoangular, vertical or horizontal, fully impacted and fully bone retained impacted lower wisdom teeth

Exclusion Criteria:

• Patients with any systemic contraindication, infection in the area of the tooth to be extracted, anamnesis of sensitivity to paracetamol derivatives or aspirin, pregnant or breastfeeding patients, and patients using antibiotics or anti-inflammatory drugs in the last 3 weeks
• In addition, smokers or alcohol addicts were not included in the study.
