Digital and Conventional Clasp-retained Partial Dentures (DIGICLASP)

This single-center prospective observational cohort study evaluates two fabrication workflows already in routine clinical use for clasp-retained removable partial dentures (RPDs): a digital workflow (Group 1) and a conventional workflow (Group 2). The fabrication workflow is selected as part of routine clinical care and is not assigned by the study. Separately for the digital and conventional workflows, the study describes the cumulative active clinical chairside time (primary), together with the number of clinical appointments, dental laboratory process times, quantitative and clinical framework fit, adjustment effort, final fit, and the frequency of rework and remake. Consecutive patients treated at the Department of Reconstructive Dentistry and Gerodontology, University of Bern, are included over a 36-month period. The analysis is purely descriptive; no causal inference, confirmatory hypothesis testing, or superiority assessment is planned.

Inclusion Criteria: * Adults aged 18 years or older * Indication for a clasp-retained removable partial denture, treated at the department during the data-collection period * Consent to the two additional, non-invasive intraoral scans performed during the framework try-in Exclusion Criteria: * No consent to the study-specific additional measures * Minors * Persons unable to give informed consent
