Research and Development of Vietnamese Bite Force Meter
Objectives: Maximum bite force (MBF) is an important parameter to evaluate the functional status of the masticatory system and the effectiveness of dental restorations. This work presented the fabrication and development of a novel, affordable and accurate bite force meter (BFM) and its application in measuring Vietnamese young adults’ MBF.
Methods: The study was conducted in two phases. In laboratory phase: Developed through 4 generations, the final BFM contains the biting part based on the strain gauge transducer to change the electrical resistance of the sensor from the applied force on the biting platform. Resistance change was then calculated and visualized using the digital processor-display part. The device's accuracy was calibrated using Morehouse Universal Calibration Machine. In clinical phase: 36 young adults (18 males and 18 females) with complete natural dentition were measured the MBF at molar, premolar and incisor on each side.
Results: The BFM has been fabricated with a 10mm-thick biting platform with two polytetrafluoroethylene layers, 0-700N measurement range with 150% overload capacity and ±1% allowable error of accuracy (certified by Sai Gon Technology Center for Measurement And Calibration). The mean of MBF among young adults were 624.64±55.91N, 499.08±97.02N, 161.04±54,17N at the molar, premolar and incisor regions, respectively. There was no MBF significant difference between left and right sides as well as male and female.
Conclusions: The BFM could be a potential device for dental profession in Vietnam. It is needed to do more research to improve this device both technically and clinically in its design and performance.
