The Use of 3D Scanning and 5-Axis Machining in Design and Fabrication of Dental Bridge

摘要

Dental restorations are currently produced mainly by conventional dental technology methods. The automation of the manufacturing process can be achieved by the use of CAD/CAM technology. Basic research on the most important aspects of CAD/CAM fixed dental restorations from the viewpoint of production, information technology, and dentistry/dental technology are the subject of a current article. The aim of this article is practical using of computer aided technologies such as 3D scanning and 5-axis machining for designing and fabrication of dental restorations. It further explains the detailed process of acquiring a digital description of tooth's shape and its subsequent modification. Attention is drawn to a detailed analysis of dental restorations' design obtained from a digital description of a tooth in Cercon Art software. The last part of this paper concentrates on the fabrication of dental restorations, which took place at CAD/CAM dental centre in Bratislava, Slovakia. The fabrication was accomplished by 5-axis kinematic structure of machine tools.
