AIM: Aim of the study was to evaluate the long-term reliability and effectiveness of inlays and onlays in ceramic and composite material, examining scientific studies published from 2004 to 2013. The results of this review were analyzed and compared with the important literature review proposed by Manhart in 2004.
METHODS: With this review it was possible to analyze a total sample of 5858 Class I and II restorations, made in the posterior region: 5295 ceramic and 563 composite restorations in 2377 patients. Works were evaluated using USPHS, modified USPHS and CDA criteria after a mean observation period of 5.4 years (5.9 years for ceramic restorations, 2.6 for composite restorations).
RESULTS: The arithmetic average of success was 94%, higher in ceramic restorations (94.9%) than composite materials (91.1%). The weighted average success rate was 95.3%, 92.8% for composite restorations and 96.3% for ceramic ones. The highest rates of success were found in ceramic restorations notwithstanding the longer observation period.
CONCLUSION: Indirect restorations have a low failure rate and they prove to be an excellent choice in the treatment of both class I and II lesions. During the last 6 years, the parameters related to these restorations have improved, with a 4% increase of success.
