Abstract
The CAM process of a CAD/CAM system for laminate veneer restoration was developed. Laminate veneer shells were milled of ABS resin. To correlate the position of upper and lower side of shell, a precision vise and a rectanglar ABS resin block of 20.0×30.0×25.0 mm were used.
Ball-end mills 2.0, 1.0 and 0.5 mm in diameter were used for rough, medium and final manufacturing, respectively. Tool offset for the radius of each ball-end mill was given in the Z direction.
Consequently, a CAM system to mill the labial and inside surfaces of laminate veneers was developed and laminate veneers can be manufactured with high accuracy.
