Study Overview
Brief Summary
The aim of this study is to evaluate the clinical performance of E-max veneers cemented with and without using grape seed extract before bonding.
Detailed Description
Justification for undertaking the trial:
Ceramic veneers have become a popular dental procedure since its introduction because they provide excellent esthetics.1 Achieving the good esthetic results especially with ceramic veneers is probably the most challenging task encountered by dental practitioners and ceramist today. Ceramic veneers are indicated for teeth with moderate discoloration, restoration of traumatized, fractured, worn dentition and abnormal tooth anatomy.2 Many factors affect the long term success of ceramic laminate veneers. The most repeated failure patterns associated with ceramic laminate veneer were fractures, microleakage, colour change and detachment of restoration.3 The main reasons for failure were large marginal defect and fractures.4 The clinical performance of ceramic veneer has shown that the estimated survival rate for the teeth prepared with butt joint design are higher than for the teeth prepared with palatal chamfer design.5 The bonding technique, which is a time-consuming and technique sensitive procedure, is a key to the long-term success of these types of restorations. The strength and the durability of the bond between the porcelain, the luting cement and the enamel/dentin interface play an important role in the outcome of ceramic veneers, particularly when dentin is involved. 6
Expected benefits for the patient
-
Achieving a more predictable esthetic restoration while being conservative. 2. Increasing the long term prognosis of the restoration. Expected benefits for the clinician
-
Enriching the professional skills of the dentist with a new material to improve the clinical performance of the restoration.
-
Improving the confidence in the patient-dentist relationship.
