Facially generated and additively manufactured baseplate and occlusion rim for treatment planning a complete-arch rehabilitation: A dental technique

Computer-aided design and computer-aided manufacturing (CAD-CAM) technologies have been successfully integrated into the digital workflow to treat completely edentulous patients. However, the digital design and manufacturing technique of the baseplate and occlusion rims have not yet been developed into the digital workflow. This article describes a novel digital workflow using extraoral digitizing procedures, open-source CAD software, and additive manufacturing technologies to obtain a 3D patient. This virtual patient can then be used to plan treatment for a completely edentulous patient, with which the maxillary baseplate and occlusion rims are digitally designed. The workflow allows the digital determination of tooth exposure at rest, the dental midline, the location of the canines, and the determination of the occlusal plane related to the Camper plane. The digital determination of these parameters increases the predictability of the treatment, reducing laboratory and clinician time and costs.
