A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, single-center study in Turkey enrolls 120 adults needing temporary fixed prosthodontic restorations. Participants are randomized into four groups to compare different ON DENT PMMA discs/blocks and a 3D-printed resin for temporary crowns and bridges. Restorations are fabricated using standardized digital workflows and followed for up to six months across five clinical visits to measure survival, success, biological effects, and patient quality of life. The study aims to provide real-world data on the clinical performance and safety of these temporary materials. All procedures adhere to predefined inclusion/exclusion criteria and standardized laboratory protocols.
