This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This study will compare the accuracy of a new PVS impression material with an improved surfactant compared to a commercially available PVS impression material with a commercial grade surfactant. Teeth will be prepared, impressions made, ceramic onlay restorations fabricated from each PVS impression material and the restoration tried in. The marginal fit of each restoration will be assessed with the Global microscope and a digital image program. The assessment of the fit of the restoration will be used to determine the accuracy of the impression material. In addition data will be collected on the detail reproduction of both impression materials.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。本研究将比较具有改进表面活性剂的新型PVS印模材料与具有商业级表面活性剂的市售PVS印模材料的准确性。准备牙齿，制作印模，用每种PVS印模材料制作陶瓷高嵌体，并尝试修复。将使用Global显微镜和数字图像程序评估每个修复体的边缘适合性。对修复体适合性的评估将用于确定印模材料的准确性。此外，还将收集两种印模材料的详细复制数据。
