- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Technical complications (chippings) and fractures of the printed composite restorations within 5 years, which make it necessary to renew the restoration (60-month failure rate of the 3D-printed composite restorations).
- Secondary Outcome Measures
Name Time Method 1. Wear of the 3D-printed composite restorations.<br>2. The amount of difference in the expected color changes (?E) of composite restorations and natural teeth. The fab changes (?E) are calculated according to the recommendation of the International Commission on Illumination (Commission Internationale de l'Éclairage: Method of Measuring and Specifying Colour Rendering Properties of Light Sources, CIE Publication 13.3-1995, Central Bureau Of the CIE, Vienna, Austria, 1995,20 pp.; Color Research & Application, 20(3), 212-212.)
