Qualifiers

Adult patients (age: 20-60 years) of both genders.

Healthy patients (not suffering of any systematic or chronic diseases).

Able to tolerate the necessary restorative procedures.

Trial design

Design model

Parallel

Treatments tested in this trial

  • hybrid ceramic retentive overlay

    Other intervention

    Endodontically treated molars will receive indirect overlay restorations utilizing a conventional retentive occlusal box cavity design.

  • hybrid ceramic non-retentive overlay

    Other intervention

    Endodontically treated molars will receive indirect overlay restorations utilizing a minimal invasive anatomical non-retentive design.

Treatment groups

50 Participants
are divided into 2 treatment groups
Group A: conventional retentive overlay designExperimental treatment 1 intervention
Group B: minimal invasive non-retentive overlay designExperimental treatment 1 intervention
