Cerana--a new method for the restoration of teeth with prefabricated ceramic inlays.
Cerana are all-ceramic, prefabricated inlays which replace enamel and are produced in a lucite-reinforced glass ceramic. To evaluate the clinical quality of Cerana inlay therapy, 38 patients with a total of 60 inlays were examined in a retrospective cross-sectional study. The inlays were primarily of Class I type, but even Class II tunnel preparations and Class V were examined. The median age of the inlays was 1.5 years. A modified form of the California Dental Association criteria was used in the evaluation. The results show that all inlays were of excellent or acceptable character in terms of marginal fit, colour and surface roughness. None of the patients reported any post-operative symptoms of pain. One restoration had secondary caries and a fractured marginal ridge. One restoration with poor anatomical form caused by a fractured filling and one restoration with deep marginal discolouration were discovered. Although the follow-up time was short, the results show that Cerana can be considered an interesting alternative to other tooth-coloured materials on the market.
