牙弓腭侧生理性肌力测量系统及测量方法的建立

摘要

目的：建立适应口腔实际环境的牙弓腭侧生理性肌力测量系统，探索肌力在固有口腔分布的测量方法。方法根据一名个别正常牙合成年女性口腔的尺寸定制厚仅0．1 mm的薄膜压阻式传感器，研制数据采集装置和 PC 端压力显示软件，组成测量系统，经标定和测试后用该系统对其口腔主要生理状态下上牙弓腭侧5个位点的肌力进行测量，并验证系统和方法的可行性。结果建立了适应口腔实际环境的牙弓腭侧生理性肌力测量系统，实现了主要生理状态下个体上牙弓腭侧肌力的测量，证实该系统和方法的操作一致性较好。结论新建立的牙弓腭侧生理性肌力测量系统适应口腔实际环境，测量方法具有一定的可行性，应用前景良好。%Objective To develop a new measuring system individually customized for oral cavity as close as possible to the natural physiological state and to explore an approach to assess the distribution of tongue pressure during major oral functions in upper dental arch.Methods The measuring system consists of a piezoresistive sensor sheet with 0.1 mm thickness,a device for data collection and PC software for pressure display.After calibration and test,the sensor sheet was attached to five measuring points on the palatal side of upper dental arch of a female adult volunteer with individual normal occlusion to measure tongue pressure during major oral functions. Feasibility of the new measuring system and method was evaluated.Results A new measuring system as close as possible to the natu-ral physiological state was developed.Measuring method based on this system achieved satisfactory operation consistency.Conclusions The new measuring system and method is feasible and useful for future research with good application prospect.
