Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome of the study is the rate of ceramic fractures (USPHS criteria) at 1, 3 and 5 years | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints will be assessed at each follow-up visit (1, 3 and 5 years). • The marginal bone level will be assessed on a periapical radiograph. • The biological outcomes will be assessed by measuring the pocket depth with a periodontal probe and bleeding on probing. • The crown survival will be assessed by means of standardized USPHS criteria. • The wear rate of the crown and the antagonist will be assessed by means of a silicone impression. | — |
