Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to examine the durability of endocrowns, created using various materials and manufacturing techniques with a fully digital workflow, and their ability to maintain functionality and aesthetics in the oral cavity.

The main questions it aims to answer were does effect of different materials on clinical success?

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Based on the power analysis, it was determined that restorations would be applied to 11 teeth in each of the three material groups (lithium-disilicate reinforced glass-ceramic, polymer infiltrated ceramic, and 3D-printed permanent hybrid resin) as well as the control group (n=11). A total of 33 teeth received endocrown restorations. Additionally, 11 patients were directly restored with composite resin in molar teeth with MOD cavities.

The digital impressions of the patients receiving endocrown restorations were recorded using an intraoral optical scanner and sent to a specialized dental laboratory. For two of the groups (lithium disilicate-reinforced glass-ceramic, polymer infiltrated ceramic), restorations were fabricated using block milling, while for the third group (permanent hybrid resin), restorations were produced through 3D printing. The restorations were cemented adhesively. The restorations were evaluated using the Modified FDI and Modified USPHS criteria at baseline (0) and at the 6-month follow-up, and the data were subjected to statistical analysis.

At the 6-month evaluation, a statistically significant difference in color match was found between the groups based on the Modified FDI criteria, whereas no statistically significant differences were observed for any of the Modified USPHS criteria. All endocrowns produced with the three different materials survived and showed clinical success at the 6-month follow-up. Nevertheless, additional clinical studies with extended follow-up durations are required.
