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.

本研究的目的是调查遥测系统中全口义齿咀嚼时偏位的发生率。遥测系统由发射单元和接收单元组成。变送器单元嵌入下部全口义齿。发送器允许6路咬合接触数据。数据遥测采用时分多路通信方式。建立双侧上下颌全口义齿平衡咬合后，在左、右第一磨牙下部插入特殊的开关，测量侧移时的咬合接触情况。同时记录咬合接触情况和下颌运动情况。研究对象为老年无牙列男性。他习惯咀嚼的一面是对的。结果如下：1.右侧咀嚼时，短缩闭合占总闭合的36.0%~71.1%，左侧为4.9%~20.9%。移位闭合以从侧位向中心位滑行为主。下颌第一磨牙牙合面侧移滑动宽度主要集中在0.8 mm~1.2 mm。
