Official title
Comparing the Clinical Success of Milled and 3-D Printed Composite CAD/CAM Full Cuspal Coverage Onlays
Overview
This is a single-center, ten-year, randomized controlled, split-mouth clinical trial. A total of 164 adult patients requiring full-cuspal coverage onlays will be enrolled. Each participant will receive one milled and one 3-D printed restoration, randomly assigned.
Detailed description
Restorations will be evaluated at 1 week, 6 months, and 1-10 years using the revised FDI criteria for indirect restorations. The primary outcome is the survival rate of the onlays.
Interventions
- Device full cuspal covarage onlay
Composite onlays prepared with CAD/CAM technology
Primary outcome measures
- The rate of survival of the onlays at the specific time points [Time frame: Survival will be evaluated at specific follow-up time points (1 week, 6 months, 1 year - 10 years)]
Eligibility criteria
Inclusion criteria
- The presence of two teeth requiring restorative treatment (onlays) because of primary or secondary caries or final restoration is needed after root canal treatment, with adjacent and antagonist teeth
- At least two walls (buccal and oral) with a minimum length of 2.5 mm and a width of 2 mm
- The deepest point of the tooth structure should be above a minimum of 3 mm of supracrestal
- The crown-to-root ratio is minimum 1:1
Exclusion criteria
- Inadequate oral hygiene
- Pregnancy
- Allergies to restorative materials
- Parafunctional habits (e.g., teeth grinding or clenching)
- Presence of orthodontic appliances
- Premolars that have undergone root canal treatment
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
