The Development of Smart Dental Unit

This development of smart dental unit is the collaboration between College of Biomedical Engineering, Rangsit University and C.C. AUTOPART Co., Ltd. The purpose of this project is to develop the smart dental unit system to obtain product certification for Thai Industrial Standard and reduce the import of medical instruments from foreign country. The development process started from review, the research prototype development and efficiency improvement that comply with the Thai Industrial Standard. In this study, the research team focused on the technical development process and the functional corrections of the dental unit system in order to obtain the test results conform with laboratory standards, which consists of two main components as follows: (1) Structure of dental chair have made from cast iron that can be operated by using PIC18F26K22 microcontroller and (2) Online monitoring and notification system which are; Water Pressure System in the range of 2-8 Bar, Main Air Pressure in the range of 4-12 Bar, Air Pressure of Dental Bur in the range of 2-6 Bar, Core Voltage in the range of 184-240 VAC., Hydraulic system which has 100-300 mA., Solenoid Valve which active in the range of 100-300 mA., Electric Current of Dental Lamp which has range between 100-300 mA, Oil level (HL) and Safety Switch can save the data to the server at a prescribed period of time from 1 to 30 minutes. The preliminary test results of both parts were established from the NECTEC and PTEC labs, respectively. The results show that they are in accordance with TIS 2610-2556 and the prototype has the potential to a commercial product in near future.
