Drilling machines designed for drilling holes in dental prostheses during manufacturing and/or repair. These machines typically consist of an electric-powered unit including a high-speed rotatory motor, a manually or automated operated rotating assembly (also known as spindle) that includes a dedicated jig and associated detachable (e.g., 1/16 to 1/4 inch/1.6 to 6 mm) drill bits or burs. The machine also includes a support (e.g., a vise clamped to a table) for the piece that is being drilled and also may include a guide and a depth control for the perforation. Dental drilling machines are intended for use in dental laboratories to obtain accurate perforations in dental prostheses; dedicated machines using laser beams as a guide are also available to perform small and accurate perforations.
