The manual cutting devices are a traditional way of performing dental surgery. They involve the use and manipulation by hand, which can cause microfractures in bone or soft tissue as well as significant damage around it leading to complications like inflammation that slows down healing process for patients who undergo these treatments postoperatively.

The piezoelectric device is an amazing tool for operating on patients because it allows less collateral tissue damage and increased visibility. They work by using ultrasonic vibrations, which stimulate cellular metabolism while producing little noise compared to motorized equipment; they also require no applied pressure, making them safe enough even when used near sensitive areas where there could be permanent scarring due if pressure were present during surgery.
