This clinical investigation is conducted to prove the long-term clinical performance of a new printable denture base material. The aim of this study is to assess the failure rate, the quality and functionality of the full dentures made with the printable denture base material over an investigational period of 5 years.
The overall objective of this clinical investigation is to evaluate the clinical safety and performance of the new flowable composite TM Flow and the new sculptable composite TM Fill for restoration of class I and class II cavities. The fillings are assessed according to selected FDI (Fédération Dentaire Internationale) criteria at baseline (7-10 days after placement of filling) and after 1, 6, 12, 24, 36 and 60 months.
The overall objective of this clinical investigation is to evaluate the clinical safety and performance of the new flowable composite TM Flow for treatment of non-carious cervical lesions. Each participant receives two different fillings (test- and control material) in two different teeth. The fillings are assessed according to selected FDI criteria at baseline (7-10 days after filling placement) and after 1, 6, 12, 24, 36 and 60 months.
This retrospective study investigates the longevity of dentures with SR Phonares II teeth after a wearing period of more than 10 years. The primary objective is to assess the survival rate of dentures with SR Phonares II teeth after more than 10 years.

The last decades have seen a significant increase in myopia in children and young adults. Possible cause: increased near-work (school, computer, smartphone). Rationale: Reading glasses support the accommodative effort of the eyes. By wearing reading glasses, there is less interference with the young eye´s physiological axial growth despite increased near-work. Main objective: does the use of reading glasses during near-work in children and adolescents reduce the incidence of myopia.
A post market clinical follow up study (PMCF) with a glass ceramic to ensure the safety and efficacy of the product. It is a study with single-arm in which inlays and onlays for molars and premolars are adhesively luted.

The objective of this study is to evaluate the clinical performance of F-Composite 2 system in Class I and Class II cavities in permanent teeth. The materials of the system can be polymerized in short time with a curing light which is part of the system. The study will be carried out as a prospective study, with evaluation of the restorations after 7-10 days (baseline), at 6 months, at 12 months, at 24 months and 60 months according to defined criteria.
