全口义齿的二次上架与三次上架

The remounting and third-remounting of Complete Denture

二次上架与三次上架是对全口义齿进行必要的咬合调改,目的是确保义齿能够与患者口腔结构良好适合并具有良好的咬合关系。二次上架一般在技工室由技工完成,内容是将基托成型后的义齿连同无牙颌模型一起复位至原先架上。通过原有颌位关系记录指导消除因义齿制作过程造成的咬合问题。与二次上架不同的是,三次上架则是由医师在临床完成。医师在进行全口义齿初戴时,重新记录患者上下颌的颌位关系,并将其与新义齿转移至架上进行最终的咬合调整。经过二次与三次上架的操作,全口义齿能够在患者口内具有良好的咬合关系。

The primary objectives of the remounting and third-remounting for complete denture are to perfect the adaptation of the complete dentures to the oral structures and to make the necessary corrections to obtain perfect harmony in occlusion. The remounting is usually performed in the laboratory by the technicians, who will reseat the edentulous casts with attached dentures on the articulator. The original record of the edentulous jaws relation will instruct how to correct occlusal discrepancy produced during denture base processing. Unlike the remounting, the third-remounting is performed in clinic by the dentists. It will retake the centric relation record of the edentulous jaws using the new complete dentures in the patient~ mouth and transfer them to an articulator again. In the articulator the dentists will make the definitive occlusal correction before the delivery. The remounting and third-remounting will guarantee the ideal occlusal relation of the new denture in the patient＇s mouth.
