制作全口义齿,颌位记录是一个关键步骤。有些无牙颌病人习惯前伸下颌及其它不良习惯的咬合,往往使(上合)关系记录不准确,造成全口义齿失败。今年我们用验平面磨牙区加蜡完成正中验关系记录。由于下颌无蜡堤,病人下颌活动自如,咬合时只有上颌磨牙区的蜡块与下颌牙嵴接触,病人就会主动意识向后咬合,下颌自然退到正中(牙合)位。加上的蜡块只在(牙合)平 Making complete dentures, jaw position recording is a key step. Some edentulous patients accustomed to stretching the lower jaw and other undesirable habits of the occlusion, often make (Shanghe) relationship records are not accurate, resulting in complete denture failure. This year we use the experimental plane grinding area plus wax to complete the relationship between the test records. Due to the mandibular wax-free dimples, the patient's mandible is free to move. Only the wax blocks of the maxillary molar area engage with the mandibular crest during bite. The patient will actively bite back and the mandible naturally retreats to the middle of the occlusion. Add wax block only in (occlusal) flat
