A new articulator is described which has the advantages of the rigidity of a simple articulator in the upper member and the flexibility of an adjustable articulator in the lower member. A link between the members and the frame along with the posterior controls establishes a full range of functional chewing movements and defines the extreme lateral or border paths. The articulator has condylar element controls which permit releasing and remounting the mandibular cast in a manner that serves the same function as the split-cast technique, but this method is faster and shows the amount of discrepancy. The condylar element control is an improvement over existing devices for comparing interocclusal records in that it not only indicates differences in position but it also provides quick remounting of the casts in a working articulator. Other features of the articulator are: (1) a condylar lock mechanism which is activated by only a half turn, (2) adjustable spring tension, (3) precise long centric and wide centric controls, (4) an incisal pain which can be removed and replaced on the articulator without changing its setting, (5) a Bennett movement carefully selected to avoid the complication of a pantograph type of face-bow, and (6) a new sponge wall type of mounting plate which supports both casts for simultaneous mounting.
本文描述了一种新型牙合架，其优点在于上部部件具有简单牙合架的刚性，而下部部件具有可调节牙合架的灵活性。部件与框架之间的连杆以及后部控制装置可实现全范围的功能性咀嚼运动，并确定极端侧向或边缘路径。该牙合架具有髁突元件控制装置，可允许以下颌模型的方式释放和重新安装，其功能与分铸技术相同，但此方法更快且能显示差异量。髁突元件控制装置是对现有用于比较咬合记录的装置的改进，因为它不仅能指示位置差异，还能在工作牙合架中快速重新安装模型。该牙合架的其他特点包括：(1) 只需旋转半圈即可启动的髁突锁定机构；(2) 可调节的弹簧张力；(3) 精确的长正中位和宽正中位控制；(4) 切导可在不改变其设置的情况下在牙合架上拆卸和更换；(5) 精心选择的Bennett运动，可避免使用面弓式的复杂情况；(6) 一种新型海绵壁式安装板，可同时支撑两个模型进行安装。
