Radial Ultrasonic Assisted Dental Handpiece Oral High-speed Grinding and Restoration Simulation Device

Abstract

The invention discloses a radial ultrasonic assisted dental handpiece oral high-speed grinding and repairing simulation apparatus. The supporting system of the apparatus is composed of a baseboard, a top board and columns, a force measurement system is arranged at the lower portion of the supporting system, the top board is provided with a three dimensional coordinate system, the three dimensional coordinate system is composed of an X-direction slide bench, a Y-direction slide bench and a Z-direction slide bench; and the upper surface of the force measurement system is provided with a radial ultrasonic vibration system. In the grinding process, the ultrasonic vibration system provides radial ultrasonic vibration for a piece, and the three dimensional coordinate system acts according to a movement control signal, and drives a dental handpiece to carry out three dimensional locus grinding processing on the workpiece according to an established locus; and a force measurer is used to determine and monitor the grinding force, and a relevant grinding signal is acquired and analyzed through an external test system. The apparatus realizes three dimensional controllable movement of the dental handpiece, and can carry out three dimensional ultrasonic vibration grinding and repairing test on various dental materials.

Description

Technical field [0001] The invention relates to a simulation device for tooth preparation and oral restoration material cutting and grinding adjustment, in particular to a radial ultrasonic assisted dental handpiece oral cavity high-speed grinding adjustment and restoration simulation device. Background technique [0002] With the development of science and technology, the demand for hard and brittle materials, difficult-to-process materials and new advanced materials is increasing, and higher requirements are put forward for the processing efficiency, processing quality and processing accuracy of key parts. Traditional grinding methods inevitably produce large grinding force and grinding heat, causing a series of problems such as surface / subsurface damage of the workpiece and low grinding wheel life. Especially in the field of precision and ultra-precision machining, the existence of these machining defects seriously restricts the improvement of parts machining accuracy and mach...
