Embodiment Construction

[0023] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] see figure 1 , a kind of multi-color resin denture prosthetic integrated rapid prototyping method of the present invention of the present invention has the following steps:

[0025] 1) Obtain the patient's edentulous plaster model and (occlusal) tray;

[0026] 2), scan the obtained plaster model and (occlusal) bracket with a three-dimensional scanner for dental and jaw models;

[0027] 3) Register the plaster model and (occlusal) bracket obtained by scanning, and import it into the software of the CAD / RP technology-based full denture design and production method. After creating the occlusal plane and dental floss, use the parameter-based Search and arrange the upper and lower teeth in the three-dimensional graphic database of complete denture and artificial teeth, complete the CAD of the dentition data, and complete the CAD of...

Abstract

The invention relates to an integrated rapid prototyping method for a multicolor resin denture restoration. The method includes steps of scanning a plaster model of an edentulous jaw and an (occlusion) rest of a patient, building an (occlusion) plane and tooth arranging lines, arranging lower and upper teeth, completing dentition CAD data, completing rest CAD data, introducing denture CAD data into bundled software of numerical control machining equipment, setting color layers distinguished by color type numbers at the normal direction of the (occlusion) plane according to clinical colorimetric results with each of the layers representing one color, labeling beginning and end planes of each of the color layers at the normal direction of the (occlusion) plane with the planes being adopted as interfaces for changing material yarn with different colors, and performing multicolor complete denture prototyping through applying the numerical control machining equipment, the bundled software of the equipment and the PMMA material yarn, thus completing manufacturing of a complete denture. The method simplifies manufacturing steps, meets artistic requirements of multi-layer color of complete dentures and achieves accurate prototyping.

Description

technical field [0001] The invention relates to a digital processing and molding method for a denture restoration, in particular to an integrated rapid prototyping method for a multi-color resin denture restoration. Background technique [0002] CAD / CAM technology has been widely used in dental multidisciplinary. Dental restoration CAD / CAM system mainly includes three parts: data acquisition, computer-aided design and computer-aided processing. After more than 40 years of research, this technology has occupied a place in the field of fixed oral restorations, and it well reflects the superiority of CAD / CAM technology, improves efficiency, reduces the labor intensity of medical technicians, improves the quality of restorations, and is accurate and weakened. Due to the influence of factors such as the experience and personal quality of medical technicians, etc. [0003] With the aging population in our country, the number of edentulous patients is still high. Complete denture...
