Abstract

This project aims to research and develop an ultra-sound tartar remover for use in dentistry, employing totally national mechanical and electronic solutions. The equipment used to remove tartar, also known as scalers, come in two types: pneumatic or ultra-sound. The latter offers advantages in terms of durability and efficiency, but is inaccessible to most dental surgeons due to its high cost. The research and development of this equipment will operate on five work fronts involving: 1) ultrasonic scaler: uses piezoelectric elements, mounted in a mechanical unit suitable for the handling and refrigeration of the whole device (hand-piece); 2) tips: these are attached to the ultrasonic scaler, and can offer different formats depending on the procedure to be applied. Different models for tips will be developed, involving research on materials (steels) and hardening processes suited to their use; 3) solenoid valve: used to control the flow of water; 4) microcontrolled electronic control module: responsible for the control of the solenoid valve and the high tension generator, necessary for the functioning of the ultra-sound scaler (approximately 500 volts); and 5) cabinet: in which the electronic control module, the solenoid valve and the hand piece (containing the ultrasound scaler) are stored.
