Drilling machines designed for drilling small holes (i.e., pinholes) in dental prostheses during manufacturing and/or repair. These machines typically consist of a high-speed rotatory motor, a fine beam laser, and a rotating assembly (also known as spindle) that includes a dedicated jig and associated detachable very small diameter (e.g., 1/16 inch/1.6 mm) drill bits. 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 depth control for the perforation and appropriate means for extraction of dust. Laser-Guided dental drilling machines are intended for use in dental laboratories to obtain accurate pinholes in plastic prostheses using a laser guide.
