The Performance of Posterior Partial Coverage Coronal Restorations Cemented Using Two Different Luting Systems. A Comparative Clinical Trial.

NA · King Abdullah University Hospital · NCT06457737

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.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with non-vital teeth and healthy periodontium.

Not a fit: Patients with systemic diseases, poor oral hygiene, or signs of bruxism may not benefit from this study.

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 performed: While similar approaches have been explored, this specific comparison of luting systems using a preheated resin composite is relatively novel.
