学研究的进展,对总义齿修复时的颌位问题已引起学者广泛兴趣。目前,国内外某些教科书中仍强调正中关系位是总义齿建(牙合)的唯一生理颌位。本文根据哥德氏弓对总义齿颌位的验证结果,同一病人在不同颌位制作二副总义齿的效果比较,总义齿选磨和使用后对颌位的影响等资料分析,得出总义齿在建(牙合)时和自然牙列一样存在着恢复一位或二位的问题,正中关系位并非是每个病人的最适颌位,多数病人的最适颌位在其稍前方的肌肉闭合道终点。文章还对正中关系位在建(牙合)中的作用,如何获得正中关系稍前方位等问题作了探讨。
Advances in 學 research, the total denture repair jaw position has aroused widespread interest. At present, some textbooks both at home and abroad still emphasize that the median relationship is the only physiological jaw position of total denture construction. Based on the results of the verification of the maxillary dentition jaw position by the Goths' bow and the comparison of the effect of two total dentures made by the same patient in different jaw positions, the effect of the total denture dressing and post-use jaw position, the total denture There is a problem of recovering one or two patients during dentition occlusion. The median relationship is not the optimal jaw position for each patient. Most patients have the optimal jaw position in the muscle just before Closing the end of the road. The article also discusses the role of the median relationship in the construction of an occlusion and how to obtain the position of the middle relationship a little earlier.
