Clinical Efficacy of a New Piezoelectric Technique for Wisdom Teeth Extraction

Clinical Efficacy of a New Piezoelectric Technique for Wisdom Teeth Extraction Without Using Manual Tools: a Clinical Randomized Controlled Study.

the aim of this randomized controlled clinical study is to evaluate the efficacy of a new piezoelectric technique for wisdom teeth extraction without using manual tools versus the conventional one.Patients referred to the hospital of Bolzano for wisdom tooth extraction will be randomly divided in two groups. In the test group all the procedure will be performed using piezoelectric instruments, while in the control one conventional manual instruments will be used. Main outcome measures are patient pain and complications, secondary outcome measures are duration of the surgical treatment and soft tissue healing

Wisdom teeth extraction can be difficult and patient can suffer post operative swelling and pain. A new piezoelectric technique for wisdom teeth extraction was developed and it showed promising results in terms of surgical effectiveness and patients post operative complications. The aim of the study is to compare the new technique with special designed piezoelectric tools with the traditional one in a randomized controlled way. The same procedures are to be followed for teeth extraction except for the use of a piezoelectric lever in one group and a manual lever in the other one. The study is a mono-center, pragmatic, randomised clinical trial (RCT) of parallel group design. The trial would have one week follow up. All patients referred to the Dental Department of S.Maurizio Hospital (Bolzano, Italy) for the extraction of wisdom teeth are considered eligible for the study.
