Wireless Sensor Network for A Bite Force Recorder

Abstract

Maximum bite force of an individual is one of the most important perimeters which correlate with the wellbeing of the oral health of a person. The measurement of bite force can provide a useful data for the evaluation of jaw muscle functions and activities. It is also an adjunctive value in assessing the performance of a dental prosthesis. There are many bite force recorders in the market, however, the devices have many drawbacks in terms of accuracy, reproducibility, high costs, and infection control for intraoral application, which further limit its usage and effectiveness. The purpose of this innovation is to develop a wireless, handy, cost effective and reliable bite force recorder device in which can be produced in-office using a 3-D printer. Arduino Nano microcontroller connected to a Bluetooth module was used for a wireless connection to a smartphone. The bite gauge was specially design using computer aided design software and produced using 3-D printer. Flexi force™ sensor system that was attached to the bite gauge was used to measure the bite force. The consistency and accuracy of the bite force recorder was reaffirmed by laboratory calibration and the result showed good linearity as well as excellent repeatability of the forces reading. Pilot study on human subjects was conducted to see the range of normal bite strength in adults. The positive demonstration found in this study suggests reasonable feasibility of using this device for dental application.
