摘要：

目的　对6例口颌系统功能基本正常而需要建的中老年重度磨耗患者正中关系(CR)的可重复性进行评价。方法　铰链轴法确定髁突运动轴点,关系采用三维电子式髁突运动描记仪Pantronic记录并转移至 Denar D5A型全调节式咬合架上,用双手扶持法对6例需要建的重度磨耗患者CR在不同体位下髁位的可重复性进行评价。结果　患者仰卧位时,在前后方向,CR的位移量平均为0·14 mm;在上下方向,CR的平均变化量为 0·11 mm。患者直立位时,在前后方向,CR的位移变化量为0·35 mm;在上下方向,CR的位移量在0·20 mm。CR在上下方向的稳定性和重复性要高于前后方向。结论　在口颌系统功能正常的情况下,CR的稳定性和可重复性好, 在咬合治疗和功能重建中,是比较理想的参考治疗位。

Abstract:

Objective　Standards for determining mandibular position, especially the centric relation (CR), are in cont- roversy because of anatomical, neurophysiological factors and research methods or instrument. The purpose of this studywas to re- evaluate the reproducibility of centric relation of the patients with severe dental attrition for oral rehabilitation.Methods　Repro- ducibility of the centric relation of 6 patientswith severe occlusal attritionwas investigated by using D5ADenar fully adjustable ar- ticulator and the Pantronic recording system.Results　①In supine position, anterior-posterior(AP) displacement of centric rela- tion (CR) was 0·14 mm and superior-inferior(SI) displacements of CRwere between 0·11 mm~0·12 mm.②In upright position, anterior-posterior displacement of CR was 0·35 mm and superior-inferior changes of CRwere between 0·13 mm~0·20 mm.Con- clusion　The CR is the most stable and reproducible position of mandibule in normal stomatological system and is useful as a ref- erence position in occlusal treatment and functional rehabilitation.
