Long-term clinical performance of CEREC restorations and the variables affecting treatment success

Since the first patient was treated with a CEREC restoration in 1985, several system developments have expanded the indications for which this system can be applied. Concurrently, ongoing research in private practices has contributed to documentation supporting the placement of CEREC restorations based on their performance relative to specific criteria, including tooth vitality, papillary bleeding, quality of margins, quality of ceramic used, treatment required, and failures. This article summarizes the methodology and findings of the ongoing clinical evaluations of 1,010 ceramic restorations, including inlays and onlays, placed in 299 patients during a 39-month period, that were reexamined at 9 to 12 years postplacement.
