Group	Intervention	Description
onlays conventional	onlays conventional	onlays preparation design conventional as all cusps covered with shoulder finish line preparation
onlays conservative	onlays conservative	conservative onlays preparation with partial cusp coverage only defective cusps

Primary Outcome Measures

Name	Time	Method
evaluation of fracture resistance	one year	fracture resistance of restorations postoperatively: assessment of the restoration for fracture resistance , by using Measuring device Modified United States Public Health Service (MUSPHS) parameters were used to compare the restorations at baseline and final examination use explorer Measuring unit .Discrete(scores); 1. alpha no evidence of fracture; 2. bravo evidence of fracture

Secondary Outcome Measures

Name	Time	Method
evaluation of marginal adaptation	1 year	marginal adaptation of restorations postoperatively assessment by Measuring device Modified USPHS Criteria Measuring unit .Discrete(scores) use explorer; 1. alpha no visible evidence of ditching along the margin; 2. bravo visible evidence of ditching along the margin not extending to the DE junction; 3. charlie mismatch between restoration and tooth structure within the normal range of color, shade ,translucency
evaluation of patient satisfaction to the onlay restoration through questioning the patient about pain during eating , acceptability ,sensitivity	1 year	patient satisfaction of restoration use Questionnaire VAS\* Measuring device Measuring unit Numerical(discrete) ('0' unsatisfied-'10' satisfied)
