Direct inlay restorations: utilization of sonic preparation technology in conjunction with ceramic inserts

Although glass inserts have enabled the use of direct restorative procedures for the placement of inlays and onlays, these techniques are often unable to address elementary patient concerns (i.e., aesthetics, fit, expense). The advent of a novel process that standardizes preparation design and facilitates the use of advanced restorative materials may provide an alternate means of providing acceptable treatment. This article highlights the use of a sonic preparation system with ceramic inserts to develop aesthetic direct inlay restorations that demonstrate the qualities traditionally exhibited by indirect ceramic materials.
