EVALUATION OF NEW RESTORATIVE MATERIAL

这项调查的目的是评估一种新的修复剂 混合型修复材料（EXL 324），并比较其磨损 Z100（3M Co.）修复材料目前 可在牙科市场上获得并具有良好的磨损特征 数据 选用10个Z100品种和12个试验材料， 随机放置在6个M的后牙中。食蟹猴 在一个月时对两种材料进行临床评价， 当时的印象，以衡量磨损量， 直接出现在修复牙齿的塑料模型上 的 由两个评估者通过查看 在双盲研究中使用解剖显微镜。 进一步评价 材料将在三个月和六个月 间隔之后。 在实验中注意到一些磨损， 材料EXL 325一年后，但仍然 有用

The purpose of this investigation is to evaluate a new restorative hybrid type restorative material (EXL 324) and to compare its wear characteristics with Z100 (3M Co.) Restorative material presently available in the dental market and having well characterized wear data. Ten Z100 restorations and twelve experimental materials were randomly placed in the posterior teeth of six M. fascicularis monkeys. The two materials were clinically evaluated at one month and impressions taken at that time to measure the amount of wear that had occurred directly on the plastic casts of the restored teeth. The casts are evaluated for wear by two evaluators by viewing through a dissecting microscope in a double blind study. Further evaluations of the materials will be made at three months and at six monthly intervals thereafter. Some wear was noted on the experimental materials EXL 325 after one year but restorations were still serviceable.
