Inclusion criteria
Inclusion criteria: Patients have to meet the following criteria to be included: - need for custom-made tooth- and / or implant-supported single-unit and / or multi-unit fixed dental prostheses in the anterior and / or posterior region due to primary caries (proximal, occlusal, cervical, root, early childhood caries) or non-caries hard tissue defects (e.g., erosive tooth wear, abrasion, fractures/cracks or trauma) or dental developmental disorders (e.g., molar-incisor-hypo mineralization or hereditary disorders of enamel/dentin) or other specific situations, e.g., restorations to im-prove aesthetics due to discoloration or diastemas; and - all gender; patient age 18 to 65 years (reducing the natural mortal risk due to a 10-year timeframe study); and - patient must be informed about the advantages and disadvantages of the different forms of care as well as the possible risks and complica-tions associated with them; and -requirement for patient self-management. The patient must be able to practice adequate oral hygiene and attend regular follow-up appoint-ments.
Exclusion criteria
Exclusion criteria: Patients will not be included in the study if one or more of the following criteria apply: - patients who refuse to participate in the research; - patients who represent systemic conditions or chronic diseases that re-quire differentiated care and follow-up (preapical inflammation and exist-ing periodontitis; insufficient root fillings with imflammation); - pregnant women; - patients with insufficient tooth-structure availability, insufficient prepara-tion, insufficient oral hygiene or heavily discolored hard tooth structure; - under 18 years of age, due to the generally large pulp cavity (exceptions include: adhesive bridges, non-vital teeth, tenon teeth); - patients with more than two contiguous pontics in the posterior region or more than three contiguous pontics in the anterior region; - patients with known incompatibilities with respect to the components.
