Prerequisite for treatment with dental implants is a thorough risk assessment. This includes evaluation of bone, soft tissue, and prosthetic parameters, and should also consider the patient's expectations. Clinical examination is followed by diagnostic radiologic imaging to visualize the anatomic requirements. The SAC classification, which categorizes the complexity of the individual case as straightforward, advanced, or complex, is suitable for detailed risk evaluation. For implantation in the esthetic region, the Esthetic Risk Assessment is also recommended. The treating implantologist has a responsibility to achieve clinically predictable and reproducible results. This requires adequate diagnostic procedures and risk assessment, on the basis of which an evidence-based treatment concept can be established. Furthermore, the patient must be appropriately informed about the planned treatment—including its complexity and the associated risks—in order to arrive at a joint consensus.
