Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study explores an alternative approach using a pre-heated restorative resin composite as a luting material of partial coverage restorations on upper and lower posterior teeth. It will follow a split-mouth design with 60 participants selected based on strict criteria. Assessment at 6 months and 1 year post-delivery utilizes a modified model of USPHS criteria, evaluating retention, color match, marginal discoloration, secondary caries, anatomical form, marginal adaptation, and surface roughness.

The null hypothesis:

The use of preheated resin composite for cementing partial coverage restoration will not result in significantly superior clinical performance when compared to that after using dual-cure resin cement.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The adhesive cementation of ceramic partial coverage restorations is a technique-sensitive process essential for achieving optimal retention and marginal integrity. While dental resin cements are commonly used for adhesive luting of indirect ceramic restorations, concerns exist regarding their long-term reliability due to susceptibility to degradation over time and polymerization shrinkage-related issues.

This study explores an alternative approach using a pre-heated restorative resin composite as a luting material of partial coverage restorations on upper and lower posterior teeth, aiming to address these drawbacks. It will follow a split-mouth design with 60 participants selected based on strict criteria. The preparation and delivery appointments follow specific guidelines, incorporating the Morphology Driven Preparation Technique (MDPT). Assessment at 6 months and 1 year post-delivery utilizes a modified model of USPHS criteria, evaluating retention, color match, marginal discoloration, secondary caries, anatomical form, marginal adaptation, and surface roughness.

The objectives of this clinical trial are to evaluate the clinical performance of posterior partial coverage coronal restorations utilizing two different luting systems (preheated resin-based composite versus conventional dual-cure resin cement) in a split-mouth study design.
