Inclusion criteria
Inclusion criteria: Volunteers that require tooth replacement with an implant-supported single crown in one posterior quadrant in the maxilla or mandible; age from 18 to 70; good oral hygiene; periodontal health or successful periodontal therapy; at least one adjacent tooth/restoration; presence of antagonistic contacts
Exclusion criteria
Exclusion criteria: Volunteers with dental implants exhibiting biologic complications before the fabrication of the definitive implant-supported single crown; severe parafunctional habits; lack of occlusal stability
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Similar technical complication rates of the implant-supported single crowns are expected, through clinical evaluation, during a 3-year period. | — |
Secondary
| Measure | Time frame |
|---|---|
| Similar biological complication rates of the implant-supported single crowns are expected, through clinical evaluation, during a 3-year period.;Similar volume loss of the antagonist teeth/restorations is expected for the two groups using intraoral scanning procedures and software analysis after 3-year follow-up. | — |
