Abstract: A dental abutment system including an abutment, an inlay and screw, wherein the screw at least partially occupies the interior channel of the inlay. A method of manufacturing a dental abutment system and to a control data set including a plurality of control instructions that are configured to, when implemented in an additive manufacturing system, to cause the system to execute at least the step of forming an abutment at the distal end of an inlay using an additive manufacturing process. The screw is a captive screw. The interior channel of the abutment is variable in diameter and the smallest diameter is ≥102% and ≤110% of the width of the screw head and the longitudinal axis of the interior channel of the abutment and the longitudinal axis of the interior channel of the inlay are angled with respect to each other at an angle of ≥5 degrees.

Abstract: A system is disclosed for manufacturing a dental workpiece. The system may have a subtractive machine configured to manufacture a base of a dental device from a material blank, and an additive machine configured to manufacture a top of the dental device by adding material onto a surface of the base. The system may also have a controller in communication with the subtractive machine and the additive machine. The controller may be programmed to receive digital data corresponding to a mouth of a particular patient, and to control operation of the subtractive machine to customize the base based on the digital data.
