Copy milling to duplicate the emergence profile for implant-supported restorations
Publication date: Available online 1 October 2019Source: The Journal of Prosthetic DentistryAuthor(s): Julian Conejo, Pablo J. Atria, Ronaldo Hirata, Markus B. BlatzAbstractThis technique article describes the duplication of a definitive implant-supported computer-aided design and computer-aided manufacture (CAD-CAM) crown with soft-tissue modification on a misplaced implant. Gingival contours were ideally shaped in the stone die, and a custom healing abutment was designed. After scanning the modified surface, images were correlated with the initial intraoral digital scan, and the definitive restoration was designed, mille...

Architecture and design of a robotic mastication simulator for interactive load testing of dental implants and the mandible
ConclusionsThe developed system facilitated the teeth-replacement procedure. The PKM accomplished the execution of mastication cycle involving 6 degrees of freedom, enabling any translation and rotation in sagittal, horizontal, and vertical planes. The mechanism can simulate the human mastication cycle and has a force application range of up to 2000 N. The designed load-sensing element can record interactive forces within the range of 200 N to 2000 N with fast response and high sensitivity to produce a robotic mastication simulator with custom-made modules.
