Mastication is receiving an influence of anterior guidance. However, there are few reports that examined about the relation between mastication and anterior guidance. Lateral guide participates a significant function of anterior guidance. The aim of this study is that examines about an influence of changing of lateral guide upon the masticatory movement. An experiment was carried out total 4 subjects without canine occlusal contact with intercuspal position, consisted 3 male volunteers who do not have any TMD symptom and one female TMD patient. Two kinds of metal guide were prepared, one was M type canine lateral guide which the maxillary canine mesial facet guided the mandibular canine distal facet and another was D type which the maxillary canine distal facet guided the mandibular canine mesial facet. Gum mastication and masticatory like movement with empty mouth were carried out. Those movements were measured by using MM-J1 (Syoufu Co.) and a minicomputer (DEC Co.VAX Station 4000), and analyzed by a graphic terminal (Evans & Sutherland Co.PS 390).As a result, the range of mastication trace with both canine lateral guides was narrow compared with no guide, and the trend of narrowing was more M type than D type. For masicatory movements of working side condylar point projected horizontal plane, the trace of D type was more spread to retrolateral side than that of M type obviously. Masticatory like movement with empty mouth was more influenced than gum mastication by lateral guides. The trace of masicatory movement in TMD patient was stabilized by M type guide.

咀嚼受到前方引导的影响。然而，关于咀嚼运动与前引导的关系的研究报道较少。外侧导向器参与了前路导向的重要功能。本研究的目的是探讨改变侧位引导对咀嚼运动的影响。本实验采用牙尖交错位，无尖牙咬合接触的4名受试者，包括3名无TMD症状的男性志愿者和1名女性TMD患者。制备两种金属导板，一种是M型尖牙侧方导板，上颌尖牙近中面引导下颌尖牙远中面;另一种是D型尖牙侧方导板，上颌尖牙远中面引导下颌尖牙近中面。进行牙龈咀嚼和空口腔咀嚼样运动。这些运动通过使用MM-J1（Syoufu Co.）结果表明：与无侧导板组相比，双侧侧导板组的咀嚼轨迹范围变窄，且M型咀嚼轨迹变窄的趋势大于D型咀嚼轨迹变窄的趋势。工作侧髁突点在水平面投影的咀嚼运动，D型轨迹较M型明显向后外侧扩展。侧向引导对空口腔咀嚼运动的影响大于对牙龈咀嚼运动的影响。M型导板使TMD患者咀嚼运动轨迹稳定。
