ClinConnect Summary
This clinical trial is looking at two different types of thin, tooth-colored coverings called veneers that are used to improve the appearance of front teeth. One type is made from a newer, ultra-translucent zirconia material, and the other is made from lithium disilicate ceramic, which has been used for a while. The study aims to see how well the zirconia veneers hold up over time compared to the lithium disilicate veneers, especially since zirconia is known to be strong but can be harder to bond securely to the tooth.
People who might join this study are adults between 18 and 50 years old who have good oral health and healthy gums, don’t have habits like teeth grinding, and need veneers to fix small gaps, slight discoloration, or minor shape and size changes in their front teeth. Participants will receive one of these two types of veneers and will be asked to come back for follow-up visits to check how well the veneers are working and how satisfied they are with their appearance. This study could help dentists understand if the newer zirconia veneers are a good alternative for people looking to improve their smile.
