Occlusal Wear of Teeth
Conditions
Brief summary
This randomized clinical trial aims to evaluate the clinical performance of hybrid ceramic occlusal veneers cemented with two different bonding protocols: a self-adhesive bonding protocol with adhesive enhancement (BeautiLink SA cement with BeautiBond Xtreme adhesive) versus another self-adhesive bonding protocol (RelyX U200 self-adhesive resin cement with 3M UNIVERSAL bond).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Marginal discoloration | 18 months | Measuring device: Modified USPHS criteria Alpha: No discoloration on margin Bravo: Discoloration found at margin Charlie: Discoloration with penetration in a pulpal direction |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Retention | 18 months | Measuring device: Modified USPHS criteria Alpha: retained Charlie: debonded |
| Marginal adaptation | 18 months | Measuring device: Modified USPHS criteria Alpha: explorer does not catch or has one way catch when drawn across restoration/tooth interface Bravo: explorer falls into crevice when drawn across the restoration tooth interface Charlie: Dentin or base exposed along margin |
| Postoperative hypersensitivity | 18 months | Measuring device: Modified USPHS criteria Alpha: Absent Charlie: Present |
| Recurrent caries | 18 months | Measuring device: Modified USPHS criteria Alpha: no evidence of caries at the margin of restoration Charlie: evidence of caries continuous with the margin of restoration |
