Evaluating two luting systems for partial coverage dental restorations
Official title: The Performance of Posterior Partial Coverage Coronal Restorations Cemented Using Two Different Luting Systems. A Comparative Clinical Trial.
Run by King Abdullah University Hospital · NCT06457737 · Data updated 2026-11-12
This study tests whether a new pre-heated resin material works better than a regular cement for attaching partial dental crowns on back teeth in people who need them.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with non-vital teeth and healthy periodontium.
✕Probably not a fit
Patients with systemic diseases, poor oral hygiene, or signs of bruxism may not benefit from this study.

What this trial studies
This study investigates the clinical performance of two different luting systems for partial coverage restorations on posterior teeth, comparing a pre-heated resin composite to a conventional dual-cure resin cement. It employs a split-mouth design with 60 participants, all of whom meet strict eligibility criteria. Assessments will be conducted at 6 months and 1 year post-delivery, focusing on various performance metrics such as retention, color match, and marginal adaptation. The study aims to determine if the preheated resin composite offers superior results compared to traditional methods.
Why it matters
Potential benefit: If successful, this study could lead to improved longevity and performance of dental restorations for patients.
How similar studies have gone: While similar approaches have been explored, this specific comparison of luting systems using a preheated resin composite is relatively novel.
