Overview
Brief Summary
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
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
