The purpose of this study was to investigate the incidence of lateral excursions with complete denture during mastication in telemetry system. The telemetry system consisted of the transmitter unit and the receiver unit. The transmitter unit was embedded in the lower complete denture. The transmitter allowed 6 channels data of the occlusal contacts. The data was telemetered by time division multiplex communication method. After establishing bilateral balanced occlusion for experimental upper and lower complete dentures, special switches were inserted in the lower left and right first molars, to measure the occlusal contacts in lateral excursions. Occlusal contacts and mandibular movements were recorded at the same time. The subject in this study was a 64 aged edentulous male. His habitual chewing side was right. The results were follows:1. Excursive closures constituted 36.0%-71.1% of the total closures when chewing on the right side and 4.9%-20.9% on the left side.2. The majority of excursive closures consisted of glidings from lateral position to centric position.3. The width of glidings in lateral excursions on the occlusal surface of the lower first molar was mainly ranged 0.8mm-1.2mm.

这项研究的目的是研究遥测系统咀嚼过程中横向偏移的发生率。遥测系统由发射机和接收器单元组成。发射机单元嵌入到下部完整义齿中。发射器允许6个通道数据的咬合触点数据。数据是按时间分层多路复用通信方法遥测的。在建立了双边平衡的闭塞以用于实验上和下部完整的假牙后，将特殊开关插入了左下和右第一磨牙，以测量横向偏移中的咬合接触。同时记录咬合触点和下颌运动。这项研究的主题是64岁的厌恶男性。他习惯的咀嚼一面是正确的。结果如下：1。在右侧咀嚼时，剖面封闭占总闭合的36.0％-71.1％，左侧为4.9％-20.9％。2。大多数剖道封闭包括从横向位置到中心位置的滑行3。下部第一摩尔的咬合表面侧面横向偏移中滑行的宽度主要范围为0.8mm-1.2mm。
