Study Details

Study Description

Brief Summary

The current study intends to evaluate the effect of cervical margin relocation with different restorative materials on three-year clinical performance of indirect CAD/CAM onlay restorations. This study is designed to test the null hypothesis that the three-year clinical performance of onlay restorations is significantly affected by cervical margin relocation with different restorative materials.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Highly viscous glass ionomer (cervical margin relocation)
  • Procedure: Low shrinkage Flowable Composite (cervical margin relocation)
  • Procedure: Resin Modified Glass Ionomer (cervical margin relocation)
  • Procedure: Bioactive Ionic Resin (cervical margin relocation)

Arms and Interventions

Arm Intervention/Treatment
Experimental: Highly viscous Glass Ionomer

Highly viscous glass ionomer restoration is used to elevate the subgingival cervical margin in deep class II cavities before receiving cad/cam onlay restoration

Procedure: Highly viscous glass ionomer (cervical margin relocation)
different dental restorative materials used to relocate deep cervical margins before receiving onlay restorations

Experimental: Low shrinkage Flowable Composite

Low shrinkage Flowable Composite restoration is used to elevate the subgingival cervical margin in deep class II cavities before receiving cad/cam onlay restoration

Procedure: Low shrinkage Flowable Composite (cervical margin relocation)
different dental restorative materials used to relocate deep cervical margins before receiving onlay restorations

Experimental: Resin Modified Glass Ionomer

Resin Modified Glass Ionomer restoration is used to elevate the subgingival cervical margin in deep class II cavities before receiving cad/cam onlay restoration

Procedure: Resin Modified Glass Ionomer (cervical margin relocation)
different dental restorative materials used to relocate deep cervical margins before receiving onlay restorations

Experimental: Bioactive Ionic Resin

Bioactive Ionic Resin restoration is used to elevate the subgingival cervical margin in deep class II cavities before receiving cad/cam onlay restoration

Procedure: Bioactive Ionic Resin (cervical margin relocation)
different dental restorative materials used to relocate deep cervical margins before receiving onlay restorations

Outcome Measures

Primary Outcome Measures

  1. Gingival health [three year follow up]

    Gingival Index Scale from 0 to 3 will be used for evaluation considering that score 0 represents normal gigiva while score 3 represents severely inflamed gingiva

  2. modified FDI (International Dental Federation) clinical Criteria [three year follow up]

    Functional Properties of restorations: Fracture of material and retention Marginal adaptation Radiographic examination Biological Properties of restorations Postoperative (hyper-sensitivity and tooth vitality Recurrence of caries Tooth integrity (enamel cracks, tooth fractures) Periodontal Response Adjacent mucosa Descriptive scale from 1 to 5. Note: 1 is clinically excellent 5 is clinically poor. Scores(1-3) are considered sufficient The overall cumulative success rate of restorations will be evaluated
