An interventional study of hybrid ceramic occlusal veneers in Occlusal Wear of Teeth, sponsored by Cairo University. Recruiting at 1 site in Egypt. Open to participants aged 21 Years and older. Per ClinicalTrials.gov, last updated 2025-06-12.
Sponsored by Cairo University · Not applicable, Interventional, and Treatment
This randomized clinical trial aims to evaluate the clinical performance of hybrid ceramic occlusal veneers cemented with two different bonding protocols: a self-adhesive bonding protocol with adhesive enhancement (BeautiLink SA cement with BeautiBond Xtreme adhesive) versus another self-adhesive bonding protocol (RelyX U200 self-adhesive resin cement with 3M UNIVERSAL bond).
14 studies on the registry are indexed under Tooth Attrition; 5 are open to participants now.
This study's planned enrollment of 44 is above the median of 26 across 11 interventional studies indexed under Tooth Attrition.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
