Missing tooth, which shall be replaced by an implant with prosthetic restoration.
Conditions
Interventions
Group 1: - The indication was the absence of a tooth that was to be replaced with a dental implant.
- In 35 cases, the implant position was digitally planned based on a 3D diagnostics by CBCT dataset

Inclusion criteria
Inclusion criteria: The inclusion criterion was the indication for the insertion of at least one dental implant. Only patients for whom a Cone Beam Computed Tomography (CBCT) scan was indicated based on the S2k guidelines on indications for 3D radiographic diagnostics and computer-assisted implantology (DGZMK 2012, 2022) were included.
Exclusion criteria
Exclusion criteria: Exclusion criteria included minors and individuals with disabilities for whom legally valid informed consent could not be obtained. In addition, the following absolute/relative contraindications to implant placement should be observed (even though they are not specific to the study per se; Maas, 2011). These are consistent with the S2k guideline on indications for 3D diagnostics and computer-assisted implantology (DGZMK 2012, 2022), including: Children and adolescents Severe cardiovascular disease Severe coagulation disorders (coagulopathies) Autoimmune diseases / immunodeficiencies Immunosuppression after transplantation Significant metabolic disease Poorly controlled diabetes mellitus High-dose systemic corticosteroid therapy History of radiotherapy/chemotherapy Bone diseases Bone tumors Paget’s disease of bone Current or prior bisphosphonate or denosumab therapy (medications associated with medication-related osteonecrosis of the jaw, MRONJ) Substance or alcohol abuse Heavy smoking (nicotine abuse) Lack of compliance / poor adherence
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary outcomes: - 3D angular deviation of the implant axis (°), - 3D deviation of the implant base, and tip (mm). Time of measurement: - 3 months after implant placement, i.e. after healing Method of data acquisition: - Matching of 3D implant planning data, and actual clinical position of implant (3D scan of scan body fixed on implant) | — |
Secondary
| Measure | Time frame |
|---|---|
| - 2D mesio-distal deviation of the implant base, and tip (mm); - 2D vestibulo-oral deviation of the implant base, and tip (mm); - 2D apico-coronal deviation of the implant base, and tip (mm) (deviation in depth). | — |
