查询词典 method of artificial variables

It shows in clinic as tooth sensitivity, pulpitis,periodontitis,food impaction ,deformation of basifacial caused of loss of occlusal height, temporomandibular disorder syndrome, etc. The wear property of artificial tooth material will lead a direct effect to restoration result, when it exists in oral environment. It will cause tooth enamel loss too much in a very short period, if the wear property of artificial tooth superior to tooth enamel; but if it is inferior to tooth enamel, serious wear will occur on restoration occlusions, which will lead to loss of bite functions and even decrease of occlusal vertical dimension, disorder of bite functions, etc. Therefore, it is important to artificialtooth material not only it"s biotic compatibility, mechanical function, chemistry property but also it"s wear property.

当口腔中存在修复体时，人工牙材料的磨耗性能也直接影响临床修复的效果，当其磨耗性能强于天然牙釉质门时，将会引起天然牙釉质过度磨耗；当其磨耗性低于天然牙釉质时，又会在较短时期内引起修复体咬合面磨损过度，失去咬合功能，严重者甚至出现咬合垂直距离降低，咬合功能紊乱等症状因此，对于人工牙材料除了考虑生物相容性、机械性能及化学性能外，还应考虑到材料的磨耗性能，而磨耗率的测定一直是评价天然牙及人工牙磨耗性能的优越指标之一。
