Brief Summary

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

Evaluation the clinical performance of premolars restored with ceramic vonlays versus onlays using modified USPHS criteria after follow-up period of 0,3,6,9,12 months

Detailed Description

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

two groups of patients with vital premolars indicated for fixed restorations will be selected according to special inclusion criteria (n=13) in each group (total of 26). one group will receive minimally invasive cavity preparations for posterior indirect restorations either vonlay or onlay according to each group the patient will be assessed using Modified USPHS Criteria at 0,3,6,9,12 months regarding fracture, marginal integrity and marginal discoloration

Study Groups

Vonlay lithium disilicate ceramic restorations

Vonlay is a hybrid of an onlay with an extended buccal veneer surface for use in bicuspid regions where there is mostly enamel to bond to. The vonlay is less invasive, more readily repairable, less technique-sensitive to attain adequate bonding, and will leave sounder tooth structure remaining if further treatment is required in the future

Group Type EXPERIMENTAL

Vonlay Ceramic restorations

Intervention Type PROCEDURE

vonlay is a hybrid of an onlay with an extended buccal veneer surface for use in bicuspid regions where there is mostly enamel to bond to. The vonlay is less invasive, more readily repairable, less technique-sensitive to attain adequate bonding, and will leave sounder tooth structure remaining if further treatment is required in the future

Onlay lithium disilicate ceramic restorations

Onlays are used to restore large areas of decay and also used to replace old restorations, whether they are defective amalgam fillings, old cast-gold onlays, or fabricated from some other material

Group Type ACTIVE_COMPARATOR

Onlay Ceramic restorations

Intervention Type PROCEDURE

Onlays are used to restore large areas of decay and also used to replace old restorations, whether they are defective amalgam fillings, old cast-gold onlays, or fabricated from some other material
