临床研究表明正中关系(centric relation. CR)和正中(牙合)位(centric occlusion,CO)具有良好的可重复性,故在临床治疗中作为参考位置,但神经肌位(neuro-muscularposition, NM)却不具有很好的重复性。本实验旨在研究坐位和仰卧位时以上3种位置的定位和可重复
Clinical studies have shown that the centric relation (CR) and centric occlusion (CO) have good repeatability and are therefore used as a reference point in clinical treatment. However, the neuro-muscular position (NM ) Does not have very good repeatability. The purpose of this experiment was to study the positioning and repeatability of the above three positions when sitting and supine
