Fully Digitalized Workflow of Flipper Fabrication: Different Three-Dimensional Printing Strategies and Characteristics

초록

A flipper is an interim removable partial denture used for immediate esthetic restoration and space maintenance for a limited period before definitive treatment. Traditional methods for fabricating flippers are labor-intensive and manual. With the advent of technological advancement in dentistry, fully digitalized fabrication including computer designing and three-dimensional (3D) printing can be used. This study aimed to demonstrate the complete digital workflow for fabricating flippers and compare the features of different digital methods. In a partially edentulous patient, three flippers were fabricated using different digital protocols: individual printing (tooth and base parts) and combination, i.e., one-body printing and gingival layering and one-body printing and gingival coloring. Each flipper was tried into the oral cavity, and the adaptation of flippers was evaluated using the triple-scan technique. This study confirms that fully digital fabrication of a flipper is an effective method compared with traditional methods and shows various digital workflows available in 3D printing. Thus, an appropriate fabrication method must be selected for each situation.
