Embodiment approach

[0061] The present invention firstly draws the design lines of the components of the removable partial denture bracket on a solid model (such as a plaster model), then performs three-dimensional scanning, and performs three-dimensional design according to the scanned design lines. Drawing the design line of the solid model bracket provides shape guidance for the three-dimensional design of the digital bracket, which can greatly reduce the modification of the digital design, reduce the impact on the calculation speed of the design software, and improve production efficiency. As a preferred embodiment, it specifically includes the following steps:

[0062] Remove defects such as gypsum tumors on model A, and if necessary, perform the operations required by the model treatment plan in plan A, and restore the occlusal relationship of the model after completion.

[0063] According to the model design scheme in plan A, combined with the theoretical knowledge of removable partial den...

Abstract

The invention belongs to the field of oral cavity repair and repair technologies, and relates to a digital design method of a removable partial denture rest. The method comprises the following steps:firstly, drawing design lines of component parts of the rest by using a pencil on a solid model according to requirements of a doctor and design theory knowledge of removable partial dentures; and then, performing three-dimensional scanning by using a scanner to obtain a three-dimensional digital model with the rest design lines, and carrying out digital design according to the scanned rest designlines. The modification of the digital design can be greatly reduced, the influence on the operation rate of design software is reduced, the whole flow is highly pipelined, the training difficulty ofoperators is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of oral restoration and restoration technology, and relates to a digital design method for removable partial denture brackets. Background technique [0002] Metal bracket removable partial dentures have become the main choice of removable partial dentures due to their advantages of high strength, heat conduction, and relatively small size, and are widely used in the field of oral dentition defect repair. The metal bracket is the main structure of the metal bracket type removable partial denture. It is composed of retainers, connectors, rests and metal dentures. Artificial teeth and plastic bases are attached to the metal bracket. The commonly used metal material is cobalt For chromium alloy and titanium metal, commonly used molding processes include casting molding and CAM molding (including 3D printing additive molding and cutting subtractive molding). [0003] With the maturity of CAM molding technology, its high a...
