Effect of Luting Cement on Marginal and Internal Adaptation of Novel Ceramic-Reinforced Polymer Crowns: A Micro-CT Study
Micro-CT assessment of 99 crowns showed that good pre-cementation fit did not guarantee good post-cementation fit. The Hassawat-01 prototype had favourable internal adaptation before luting but larger gap increases afterward, while VarseoSmile with RelyX Unicem performed best among evaluable combinations. This indicates an interaction between intaglio geometry and cement properties, not clinical superiority.
