For the fabrication of a prosthesis, the Prosthodontist meticulously performs all the steps. The laboratory technician then make every effort/strives to perform the remaining lab procedures. However when the processed dentures are remounted on the articulator, some changes are seen. These changes may be divided into two categories: Pre-insertion and post-insertion changes, which deal with the physical properties of the materials involved (Parker, J Prosthet Dent 31:335-342, 1974). Split cast mounting is the method of mounting casts on the articulator. It is essentially a maxillary cast constructed in two parts with a horizontal division. The procedure allows for the verification of the accuracy of the initial mounting and the ease of removal and replacement of the cast. This provides a precise means of correcting the changes in occlusion occurring as a result of the processing technique (Nogueira et al., J Prosthet Dent 91:386-388, 2004). Instability of the split mounting has always been a problem to the Prosthodontist thereby limiting its use. There are various materials mentioned in the literature. The new technique by using Dowel pins and twill thread is very easy, cheaper and simple way to stabilize the split mounting. It is useful and easy in day to day laboratory procedures. The article presents different methods of split cast mounting and the new procedure using easily available materials in prosthetic laboratory.
对于义齿制作，口腔修复医生会精心完成所有步骤。然后，实验室技术人员会竭尽全力完成其余的实验室操作。然而，当将加工好的义齿重新安装在牙合架上时，会出现一些变化。这些变化可分为两类：插入前和插入后的变化，它们涉及相关材料的物理特性（帕克，《口腔修复学杂志》31:335 - 342，1974年）。分体模型上架是将模型安装在牙合架上的方法。它本质上是一个分成两部分且有水平分割线的上颌模型。该操作可验证初始上架的准确性以及模型的拆卸和更换是否容易。这提供了一种精确的方法来纠正由于加工技术导致的咬合变化（诺盖拉等人，《口腔修复学杂志》91:386 - 388，2004年）。分体上架的不稳定性一直是口腔修复医生面临的一个问题，因此限制了其使用。文献中提到了各种材料。使用定位销和斜纹线的新技术是一种非常简便、成本较低且简单的稳定分体上架的方法。它在日常实验室操作中既实用又简便。本文介绍了分体模型上架的不同方法以及在口腔修复实验室中使用容易获得的材料的新操作方法。
