In vitro assessment of thermal changes during piezosurgery and rotary osteotomy

TL;DR

This study compares the heat generated during bone cutting with piezosurgery and traditional rotary tools, showing that piezosurgery produces less heat and is safer for bone health.

Contribution

The study demonstrates that piezosurgery generates lower peak temperatures and slower heating rates than rotary osteotomy.

Findings

Piezosurgery produced much lower peak temperatures than rotary instruments.

The rate of temperature rise was slower with piezosurgery, even without irrigation.

Piezosurgery is less likely to cause thermal bone necrosis compared to rotary tools.

Abstract

High temperatures in osteotomy may result in thermal bone necrosis, which would compromise the healing process and the process of
osseointegration. Hence, temperature increase in bone during osteotomy with piezosurgery and conventional rotary tools in different
irrigation conditions were compared. Sixty bovine bone samples were examined with the help of thermocouples to define the real time
temperature changes. Even with no irrigation, piezosurgery produced much lower peak temperatures and slower rates of temperature rise
than was produced with rotary instruments. Thus, we show the claim that piezosurgery is safer in terms of thermal and less prone to bone
injuries caused by heating during osteotomy.
