Interventions
Group 1: The planned measures/examination methods are routinely performed as part of any therapy with implants.
First, planning is performed on the basis of clinical and radiographic findings. This

Inclusion criteria
Inclusion criteria: Patients with the following planning findings are restored with implants: - The intraoral condition of the patient shows a dentition with the need for a three-unit end abutment bridge. - Internal sinus lift up to 2mm allowed. - Min. implant length 8mm. - Extraction at least 3 months ago. Only early implant placement (3 - 6 months post extraction) and late implant placement (> 6 months post extraction). - Lateral bone augmentations are possible simultaneously during the surgical procedure. - The patient demonstrates good oral hygiene and compliance. - A pre-implant hygiene phase and or pa treatment must be completed.
Exclusion criteria
Exclusion criteria: - Persons under 18 or persons lacking legal capacity. - Untreated acute periodontitis with pocket depths > 4 mm. - Heavy smokers (more than 10 cigarettes per day). - Taking bisphosphonates or rank ligand inhibitors (Denuso-map) or other drugs affecting bone metabolism (e.g. Cor-tison). - Pregnant women. - Alcohol or drug abusers. - Patients with an infectious disease such as hepatitis or HIV or AIDS. - Patients with severe, uncontrolled diabetes. - Immediate implantations. - Patients with signs of bruxism. - Patients who require an internal sinus lift > 2 mm or an external sinus lift for implantation of a ceramic.implant CI due to bone resorption.
Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Survey of the survival rate of ceramic implants ceramic.implant CI. Survey of survival rates and success rates (USPHS alpha and bravo) of three-unit fixed dental prostheses on ceramic implants (ceramic.implant CI). | — |
Primary
| Measure | Time frame |
|---|---|
| Survey of the success rate of ceramic implants ceramic.implant CI. The statistical evaluation of the primary endpoint "peri-implant bone loss" is performed after data collection (approx. 5 years) by a linear mixed model with fixed and random intercept. From this model, the two-sided 95% confidence interval is calculated for the fixed intercept. If the upper limit of this confidence interval is below the non-inferiority limit of 1.09 mm, the null hypothesis is rejected and the non-inferiority of zirconia implants over titanium implants is claimed. | — |
