Randomized Clinical Trial on Direct Composite and Indirect Ceramic Laminate Veneers in Multiple Diastema Closure Cases: 2-years Follow-up

This clinical trial focuses on closing gaps between teeth, known as diastema, using two types of dental veneers: direct composite veneers and indirect ceramic veneers. The study aims to compare the effectiveness and durability of these two materials over a period of two years. The participants in this study are individuals with multiple spaces between their teeth, and the outcomes of this research could help determine which veneer material provides better long-term results, thus improving dental aesthetics and function for those with similar dental issues. Participants in this study are randomly assigned to receive either direct composite veneers or indirect ceramic veneers. The direct veneers are applied directly to the teeth using a nanofilled composite resin, while the indirect veneers involve a ceramic material that is custom-made and then bonded to the teeth. The application process for both types of veneers follows strict procedures using specialized light curing devices to ensure proper bonding. The study is double-blinded, meaning that neither the participants nor the researchers assessing the outcomes know which type of veneer each participant received, which helps to eliminate bias in the results.
