Assessment of Occlusal Veneer Restorations Performance in Posterior Teeth
Sponsor: Ain Shams University
Summary
The aim of the research is to study the mechanical behavior and clinical performance of veneers in posterior teeth. Clinical assessment and experimentation of two types of occlusal veneers will be conducted to evaluate their behavior.

Interventions
Indirect occlusal veneer (Occlusal veneer of lithium disilicate)
Split-mouth design, (right/left posterior tooth) will be restored with an Indirect occlusal veneer (Occlusal veneer of lithium disilicate). Indirectly fabricated occlusal veneers of lithium disilicate allow better control and design of the occlusal anatomy and proximal contacts, in addition to possessing better mechanical properties and fracture strength when compared to direct occlusal veneers. However, indirect occlusal veneers are lab fabricated, consequently, more clinical visits are required.
Direct occlusal veneer ( Occlusal Veneer of Composite resin)
Split-mouth design, (right/left posterior tooth) will be restored with an occlusal veneer composite resin (Direct occlusal veneer). Directly fabricated occlusal veneers are a conservative approach, however, it requires a great skill from the operator to assure good margins and occlusal anatomy. Direct veneers are fabricated from composite resin and can be finished in a single visit, but longer chair time is required, in addition to the low wear resistance compared to ceramics. However, direct occlusal veneers have the benefit of resiliency close to that of natural dental tissue.
