Survival Analysis and Clinical Follow-up Examination of All-ceramic Single Crowns

Ceramics have been used in dentistry for many years. Especially during the last few years, the development of ceramic-related technology has steadily increased, and allceramic crowns are in the process of replacing traditional gold restorations on the market. Despite the relatively long experience with the material and technology, there are still only a few clinical studies on the long-term success rates. For this paper, three different ceramic systems (In- Ceram, Empress 2, and Cergo) were examined and results compared with the findings of the existing literature. Furthermore, the clinical follow-up examinations intended to determine the extent to which subgingival restoration margins influence the periodontium.
