Food impaction treatment guide plate design and manufacturing method

Abstract

The invention relates to a food impaction treatment guide plate design and manufacturing method. The method comprises the steps of scanning and obtaining food impaction region dentition three-dimensional data; defining a boundary surface of tooth hard tissue needing to be abraded, filled and recovered; according to a selected grinding machine needle shape, designing a grinding motion path curve; according to the motion path, designing a machine needle motion guiding track, and according to the tooth hard tissue shape needing to be filled and recovered, designing a surrounding shell linked to an existing tooth hard tissue shape; performing 2 mm shelling on adjacent three-dimensional surface data near or far away from the impaction region not needing to be ground or filled as a guide plate fixing portion; fusing data of the guiding track, a filling body surrounding shell and the fixing portion, and obtaining complete three-dimensional design data of the guide plate; guiding the data of the guide plate into a 3D printer, and completing manufacturing of the guide plate. By adopting the three-dimensional digital technology, the food impaction clinic grinding / occlusion / treatment operation guide plate is designed and manufactured efficiently, and high precision and minimal invasion of the treatment process can be achieved.

Description

technical field [0001] The invention relates to a method for designing and manufacturing a dental guide plate, in particular to a method for designing and manufacturing a guide plate for food impaction treatment. Background technique [0002] The etiology of vertical food impaction is multi-source, and the incidence rate is extremely high. The results of random survey and analysis of each age group showed that 92% showed age characteristics. The older the people under the age of 60, the higher the incidence rate, and the incidence rate of the people over the age of 60 decreases. The predilection site for vertical food impaction is between the first and second molars, the upper and lower jaws are roughly the same, followed by the second and third molars, the upper jaw is more frequent than the lower jaw, and the third is between the second premolars and first molars. The incidence of upper and lower jaws is basically the same, while other interdental incidences are rare. F...

Problems solved by technology

[0004] However, at present, there is still a lack of clear, effective, simple and easy technical methods for accurate diagnosis and clinical positioning of the adjustment position, range, and adjustment amount.

The above-mentioned traditional diagnostic techniques have limitations in accuracy and efficiency, and are difficult to popularize and apply. Most of the dental adjustments are determined by the doctor's subjective judgment, which is inevitably biased.
