Problems solved by technology

The following problems exist in the existing shell-shaped dental appliance manufacturing method: Due to the different oral structures, there are large differences in individual jaw models. In order to ensure the product quality of the appliance, the existing shell-shaped dental appliance production line often uses A diaphragm with a large area causes waste of diaphragm materials and increases production costs

Embodiment

[0068] A method for determining the relative positional relationship between a diaphragm data model and a dental-jaw data model, which is used in the production process of shell-shaped dental appliances. The digital model formed, the dental and jaw data model is a digital model formed by using digital technology to perform three-dimensional modeling of the dental and jaw model in actual production. In one embodiment, the shape of the diaphragm data model is circular, and its specifications can be The selection is made according to actual production requirements. More specifically, the diaphragm data model is a circular sheet-like structure with a radius of 30mm-80mm.

[0069] like figure 1 As shown in the figure, the method for determining the relative positional relationship between the diaphragm data model and the dental jaw data model includes the following steps:

[0070] S1. Establish a space coordinate system, the space coordinate system includes an X axis, a Y axis and...

Abstract

The invention provides a method for determining a spatial relative position relationship between a diaphragm data model and a dental data model. The method comprises the following steps of: establishing a coordinate system, setting an avoiding boundary on a standard plane, limiting a coordinate axis on a diaphragm projection, calculating minimum distance values from points on a contour line of a tooth jaw projection to the avoiding boundary, and adjusting each minimum distance value to be within a set range, so as to optimize a relative position relationship between a diaphragm and a tooth jaw model; the compatibility of the membranes is verified by using a large number of dental models, the membranes compatible with different dental models are effectively selected, the utilization rate of the membranes is improved, the waste of membrane materials is effectively avoided, and the production cost is reduced. The invention further provides a diaphragm data model selection method and system, the diaphragm, electronic equipment and the like, manual operation is not needed, the efficiency of the whole production technology is improved, and the phenomenon of waste of the diaphragm in the production process is avoided.

Description

technical field [0001] The invention belongs to the technical field of dental orthodontics, and in particular relates to a method for determining the spatial relative positional relationship between a diaphragm data model and a dental jaw data model, a method for selecting a diaphragm data model for a shell-shaped dental appliance, a diaphragm for a shell-shaped dental appliance, and a method for selecting a diaphragm data model for a shell-shaped dental appliance. A hot-pressing film method in the manufacturing process of a shell-shaped dental appliance, an electronic device, and an automatic selection system for a diaphragm data model for a shell-shaped dental appliance. Background technique [0002] In recent years, orthodontic technology has developed rapidly, and shell-shaped dental appliances are more and more widely used in orthodontic cases. Compared with the traditional bracket orthodontic method, the shell-shaped dental appliance has many advantages: 1. The shell-s...
