ABSTRACT

Aim of the study: The objective of this study was to highlight the computer aided workflow for minor tooth correction in an adult case using oral splints. Material and methods: An intraoral scanner (3Shape Global, Copenhagen, Denmark) was used for performing digital impressions and a set of 3D printed casts (Photocentric® 3D printer, Photocentric Ltd, Peterborough, UK) for aligners manufacturing using the vacuum thermoforming procedure (Ministar S® machine, SCHEU-DENTAL GmbH, Iserlohn, Germany). A “guide” splint for composite buttons attachment, and four active orthodontic splints were realized. Following tooth alignment, a porcelain veneer was performed on the upper first premolar and fixed retention was established. Another intraoral scanning (assisted for accomplishment of a retainer) was performed for obtaining a 3D printed model that served as a guide for the final retention splint.  Results: All orthodontic aligners and the retention splint were realized using digital technology (CAD/CAM). The workflow was less time consuming, comfortable for the patient and the treatment outcome could be predicted with high accuracy. The outcome was excellent in terms of aesthetics and functionality. Conclusions: For minor tooth movements in adult patients, computer-aided workflow can be implemented, with positive results.
