摘要

咬合垂直距離之決定是贋復牙科學上的一個重要步驟。很可惜到目前為止還沒有很科學的方法以測定正確的咬合垂直距離。贋復牙科學包括全口義齒，可撤式局部義齒，固定贋復體，顎面贋復體，顳顎關節障礙咬合板，以及種植體支持式贋復體等六大部份。本文就此六大部門加予探討，發現到咬合靜止間隙是一個不完善的指標；因為決定此間隙的肌肉彈性本來就是多變的，而且每一個人也不一樣。雖然如此，我們無論將咬合垂直距離增加或減少，總是要留有咬合靜止間隙，而且只要咬合垂直距離正確，肌肉自然會調節出準確之咬合靜止間隙。目前雖有很多種測定咬合垂直距離之方法，我們應依病人之情況，慎重選擇恰當之方法以完成完善之贋復體。

Occlusal vertical dimension is important in all aspects of prosthodontics. Unfortunately, there is no scientific method of determining the correct occlusal vertical dimension. The amount of interocclusal rest space (IRS) is a rough guide since muscle tone, which determines the space, is variable. IRS varies greatly from one patient to the next. It will automatically be correct when the occlusal vertical dimension is correct. IRS should not be interfered with regardless of its size. Many techniques have been used for determining occlusal vertical dimension in dentulous and edentulous patients. Regardless of the technique, the occlusal vertical dimension must be determined carefully by the dentist for a successful prosthesis.
