研究概览
简要总结
This in vivo study aims to compare the marginal fit and internal fit of crowns fabricated using three different manufacturing techniques, namely traditional casting, three dimensional printing by direct metal laser sintering, and computer aided design and computer aided manufacturing milling. Metal crown will be fabricated using each technique and evaluated using the silicone replica technique. The results will help determine the most accurate method for achieving optimal crown fit, thereby improving the longevity and clinical performance of fixed dental prostheses.
