Abstract: Introducing a novel approach to overcoming a profound gag reflex and aversion to conventional dental impression procedures when fabricating a removable partial denture. The digital workflow is becoming increasingly popular in the discipline of fixed prosthodontics. Chairside digitization of a patient’s dentition is a less invasive and more comfortable procedure in comparison to conventional dental impression techniques. The advantages can be most relevant to patients with a profound gag-reflex. Currently, certain challenges exist with full digitization in the discipline of removable prosthodontics. Combining digital and conventional workflows may serve as an alternative technique to construct removable prostheses for groups who cannot tolerate conventional methods.

Clinical relevance: Many patient groups may not tolerate conventional dental impression techniques. This method offers a combination of existing techniques as a suitable alternative for this cohort.
