Details and patient eligibility

About

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

Full description

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.

44 participants in 2 patient groups

piezoelectric extraction

Experimental group

Description:

The flap will be raised using a Piezoelectric elevator, the eventual bone around the third molar crown will be removed with the same piezoelectric lever used for luxation and root extraction. The eventual rizectomy will be performed using a piezoelectric saw.

Treatment:

Procedure: piezoelectric extraction

conventional extraction

Active Comparator group

Description:

The flap will be raised using a manual elevator and the eventual bone around the third molar crown will be removed with a bone bur with a straight handpiece while the eventual rizectomy will be performed using a bone bur. Manual levers will be used for luxation and tooth extraction

Treatment:

Procedure: conventional extraction
