Correct occlusal relationships are part of the successful prosthetic treatment of edentulous patients. Occlusal checking should be performed via a remount procedure because denture base materials and fabrication procedures cannot provide dimensionally accurate complete dentures. Occlusal errors caused by the adjustment of denture bases to the denture foundation after a certain period of wearing can also be corrected by means of remounting. The following remount procedures for complete dentures are described: fabrication of transfer casts, transfer of a maxillary denture with a facebow, centric relation record, and mounting of dentures with transfer casts in an articulator with a dental stone. Deflective occlusal contacts of denture teeth in centric occlusion can be eliminated by selective grinding and by tooth-guided excursive movements. In complete denture treatment, priority is given to anterior/canine-guided occlusion.
正确的咬合关系是无牙患者成功进行修复治疗的一部分。应通过重新上架程序进行咬合检查,因为义齿基托材料和制作程序无法提供尺寸精确的全口义齿。在佩戴一段时间后,通过调整义齿基托以适应义齿承托区而导致的咬合错误,也可以通过重新上架来纠正。以下介绍全口义齿的重新上架程序:制作转移模型、用面弓转移上颌义齿、正中关系记录以及将带有转移模型的义齿用石膏在牙合架上进行上架。正中咬合时义齿牙齿的偏斜咬合接触可通过选择性调磨和牙引导的前伸运动来消除。在全口义齿治疗中,优先采用前牙/尖牙引导的咬合。
