Key Points

Snap-On PMMA provisional restorations effectively assess occlusion and esthetics in complex dental cases, enhancing patient care and planning.
A clinical case involving a 58-year-old male demonstrated the utility of Snap-On PMMA in real-time evaluation of occlusion parameters.
The workflow integrated intraoral scanning, CBCT, and digital smile design, leading to precise transfer of occlusal information.
This approach improves predictability in full-mouth rehabilitations, showcasing the adaptability of digital methods in esthetic dentistry.

Abstract

ABSTRACT Objective To highlight the application of digitally fabricated Snap‐On PMMA provisional restorations as a minimally invasive and adaptable methodology for assessing the vertical dimension of occlusion and occlusal stability during the comprehensive rehabilitation of worn dentition. Clinical Considerations A clinical case is presented involving a 58‐year‐old male with severe anterior tooth wear, multiple edentulous spaces, and occlusal dysfunction. The patient underwent full‐arch digital rehabilitation through a workflow incorporating intraoral scanning, facial scanning, cone‐beam computed tomography (CBCT), and virtual smile design. Snap‐On PMMA milled provisional restorations enabled real‐time evaluation of the proposed VDO, phonetics, esthetics, and centric occlusion in a reversible, non‐invasive manner. Their use also enabled immediate implant loading at site #22 and facilitated the digital transfer of the validated occlusal scheme from the provisional stage to the definitive CAD/CAM restorations. Definitive restorations were fabricated using monolithic zirconia and lithium disilicate, selected for their superior mechanical strength, longevity, and esthetic potential. Conclusion Snap‐On PMMA provisional restorations represent an effective diagnostic and transitional tool in the management of worn dentition. Integrated into a fully digital workflow, they enhance treatment predictability by allowing reversible clinical validation and direct digital transfer of occlusal parameters to the final prostheses. Combined with advanced restorative materials, this approach improves treatment predictability, patient satisfaction, and the long‐term clinical success of managing complex cases of worn dentition. Clinical Significance Snap‐On PMMA provisionals offer a minimally invasive, reversible way to assess occlusion, function, and esthetics before final restoration. This technique enhances accuracy and predictability in full‐mouth rehabilitations, making it highly valuable in esthetic dentistry.
