A Randomized Controlled Clinical Study aims for Clinical Assessment of CAD/CAM Fabricated Lithium-Disilicate overlay in comparison to Lithium-disilicate Endocrowns for Restoration of Endodontically Treated Teeth.
Investigators are going to compare the clinical behavior of the lithium disilicate overlay as a more conservative line of treatment for endodontic treated teeth. overlays will be compared to the lithium disilicate endocrowns .primary outcome will be marginal adaptation ,secondary outcomes will be survival and patient satisfaction . Baseline, 5, 10, 15, and 20 months follow up will extend to 20 months(Baseline, 5, 10, 15, and 20 months) .This is a randomized, controlled, parallel-group clinical trial with 1:1 allocation ratio.

marginal adaptations
Marginal adaptation will be evaluated using Modified United States Public Health Service (USPHS) criteria by two calibrated independent examiners. Scores will be recorded as Alpha, Bravo, or Charlie based on marginal integrity.
Time frame: Baseline, 5 months, 10 months, 15 months, and 20 months
marginal discoloration
change in margins colour as a result of leakage , Assessed using Modified USPHS criteria as Alpha, Bravo, or Charlie scores.
Time frame: Baseline, 5, 10, 15, and 20 months
patient satisfaction
patient acceptance to the treatment
Time frame: 20 months
