Conditions
Brief summary
the aim of present study is to evaluate clinically the fracture liability , marginal adaptation , and patient satisfaction of conservative versus conventional ceramic Onlays use e-max press to restore defective restored molar with old restoration or caries. with one or more cusp defect
Interventions
OTHERonlays conservative
Partial coverage of cusps with shoulder finish line
OTHERonlays conventional
all coverage of cusps as overlay with shoulder finish line

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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) |
