Intelligent abrasive granule jetting treatment apparatus for treating dental caries

Abstract

The invention relates to an intelligent abrasive particle jetting treatment device and a treatment method thereof for dental caries treatment, relating to abrasive grain jetting equipment. Provided is an intelligent abrasive particle spray processing device and processing method for dental caries treatment based on CDD intelligent identification technology, which can realize online defect detection and online compensation. It is equipped with spray head, spray chamber and pressure valve, throttling controller, gas cylinder, spray delivery pipe, gas delivery pipe, pressure regulator, signal processing unit and computer part. The injection head is equipped with a laser light source, a CCD image recognition camera, a jet nozzle for removing plaque and abrasive particles, a drug cleaning treatment nozzle, and a dental filling nozzle. The laser light source and the CCD image recognition camera are connected to the computer. chamber and pressurization valve. The gas cylinder is connected to the pressure regulator through the gas delivery pipe, and is connected to the three injection chambers and the pressurization valve in three ways through the throttling controller, and the signal processing unit and the pressure regulator are connected to the computer.

Description

technical field [0001] The invention relates to an abrasive particle spraying device, in particular to an intelligent abrasive particle spraying treatment device and a treatment method for dental caries treatment. Background technique [0002] Caries is one of the three major non-communicable diseases (cardiovascular disease, cancer and dental caries) that endanger human health today. The methods of treating dental caries are to use carious tissue grinding method, drug therapy, remineralization method, filling method and restoration method according to the different conditions of caries. [0003] 1) Carious tissue grinding method: It is suitable for a wide range of carious areas. Turbine drills or grinding needles are usually used to remove carious tissue, so it is difficult to control the range and angle of grinding, and it is easy to damage the pulp angle. [0004] 2) Drug therapy: It is suitable for early caries with relatively shallow caries and no cavities formed. The ...

As an application of micro-abrasive processing, Professor Chu Chuan Changyuan of Tohoku University in Japan also applied it to the removal of tooth decay (Creating new interface between tooth and biomaterials using powder-jettechnology. [International Congress Series, 1284, (2005), 302-304 ]M.Noji, K.Sasaki, T.Kuriyagawa, O.Suzuki, K.Ogawa, M.Kanehira), but it is still in the stage of experimental research, and the existing jet micromachining devices basically do not have processing state recognition and error compensation systems , while the country is currently mainly jet rough machining, there is no large-scale product processing, precision machining and micro-machining
