摘要

中心關係位置（centric relation, CR）的記錄在贋復治療中扮演極為重要的角色，尤其是當面對全口無牙病患時，全口假牙的製作涉及了牙齒相關位置及咬合的重新賦與，如果在咬合器的起始定位點錯誤，那麼再完美的咬合設計恐怕也無法順利在口腔中和諧運作，如此一來將會增加臨床上咬合調整所需要的時間和影響全口假牙的穩定性。本技術報告就全口假牙贋復製作過程中中心關係位置紀錄取得方法予以改良，以減少因咬合紀錄材料的介入，影響垂直高度及改變後續的咬合器閉合路徑，以減少排牙誤差及簡化臨床咬合調整的時間。

Centric relation record plays an important role in prosthodontic treatment. It provides an initial relation of the jaws and then related teeth position and occlusion in the articulator be set according to this position. If the initial position is wrong, the following teeth set up could not function smoothly as designed in the articulator and will increase the time needed for clinical occlusion adjustment. This technical report introduces a modified centric record taking technique for complete denture fabrication to minimize the change of the already determined vertical dimension and arc of closure in the articulator due to the interference of the material used in centric relation recording procedure.
