A Study of Pressure Distribution Measurement System for Tooth

咬合接触是牙齿、牙周组织、下颌以及相关的神经肌肉协同作用的结果。由于形态与功能不调所引起的口颌系统功能紊乱称为咬合病。牙齿上下齿间咬合力的大小和分布特性是牙科医生诊断病人牙齿咬合状况的重要依据之一。测量牙齿咬合力，国内一般采用光合片、美国Tekscan公司的T-Scan咬合测定分析仪或者采用单个传感器测量，尚无自主研发的检测牙齿咬力分布特性的测量系统。正是在这样的背景下，本文设计了一个可以测量16对牙齿咬合力大小分布的测量系统。 本论文主要研究工作如下： 1.详细讨论和研究了几种用于压力分布测量系统的传感器技术，提出了用于牙齿咬力的传感器的原理，即压阻式，选择复合材料导电橡胶作为传感器敏感...Occlusal contact is the result which cooperates by teeth, periodontium, lower jaw and interrelated nerval muscles.
