Development of new device for measuring masticatory forces
Objective: Mastication constitutes a fundamental function for nourishment and consequently human survival. The relation among teeth, bite strength and masticatory muscular activity directly influences the masticatory function. Literature presents several reports quantifying the masticatory forces, being the interocclusal distance of 25mm used for transducers. The aim of the present study was to develop a transducer for mandibular forces determination, presenting a reduced interocclusal distance, close to 10 mm, attached to a 100 Kgf load cell. After the development stage, the device was tested to identify, compare and evaluate the masticatory forces of patients presenting different dental rehabilitation procedures.
Method: The masticatory forces were assessed in 107 patients, being 52 completely edentulous, 27 presenting partial removable dentures, and 28 presenting complete dentures. The assessments (in Kgf) were obtained in isometric contraction.The data were analyzed statistically by ANOVA and Tukey’s test (5%).
Result: Results were: control group (edentulous): 51.49 Kgf + 16.24; partial removable denture group: 28.45 Kgf + 15.43; and complete denture group: 13.11 Kgf + 7.69. The control group presented greater values in comparison to the other two groups.
Conclusion: It can be concluded tooth loss and prosthetic rehabilitation, being complete or partial dentures, present great influence on the masticatory forces. The new designed transducer, presenting reduced interocclusal distance, was efficient for masticatory force evaluation, within the assessed patients.
