festooning
Pronunciation: fes-TOON-ing
The sculpting of a denture base to simulate the natural contours of gingival tissue and alveolar mucosa around the teeth.
Full Definition
Festooning refers to the carving or shaping of the labial and buccal surfaces of a denture base to replicate the natural stippled appearance and scalloped contour of the gingiva. It is a critical aesthetic and functional step performed by the dental laboratory technician before final processing of a complete or partial denture. Proper festooning ensures that the prosthesis blends naturally with the patient's oral tissues, reducing detectability. Inadequate festooning can result in an unnatural bulk of acrylic that is both aesthetically unappealing and functionally problematic. Editors encountering this term should not confuse it with 'finishing,' which is a broader post-processing step.
Usage
Usage note: Distinguish from 'polishing,' which refers to surface smoothing after festooning is complete.
