study is ended

this study was conducted to evaluate the internal fit of indirect restoration fabricated from CAD/CAM composite blocks versus ceramic blocks in badly broken vital teeth using cone beam CT

two parallel groups (n=42 restorations), patient having badly broken vital teeth minimum of two remaining wall will be randomly enrolled in this trial and receive restoration fabricated either from Grandio composite blocks or E-max ceramic blocks. internal fit evaluation of the fabricated restoration over their corresponding casts will be performed using cone beam CT just prior cementation of the restorations. data will be collected and statistically analyzed.

Inclusion Criteria:

• patients with badly broken vital teeth young adult males or females (20-50 years) good oral hygeine cooperative patients approving to participate in the study

Exclusion Criteria:

• patients with acompromised medical history severe or active periodontal disease severe medical complications lack of compliance
