This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.This trial will examine the performance of 40 single unit crowns (25 posterior and 15 anterior) for a period of at least 2 years. Crowns will be fabricated from a lithium disilicate glass-ceramic using a computer-aided design/computer-aided machining (CAD/CAM) process. Both the material and the processing equipment have FDA 510-K clearance for this clinical application. The principal investigator (PI) initiated this trial at UConn as an important complement to ongoing laboratory efforts to better understand clinical behavior and aid ongoing research into the development of validated laboratory tests of ceramic-ceramic compatibility and bulk fracture.
