Multi-color-resin denture dentition and base-support split numerical control processing and splicing forming method

Abstract

The invention relates to a multi-color-resin denture dentition and base-support split numerical control processing and splicing forming method. The method includes the steps that an edentulous jaw patient plaster model and a (occlusal splint) support are scanned; after a (occlusal splint) plane and tooth arranging lines are built, upper teeth and lower teeth are arranged, and dentition CAD data are completed; base-support CAD data are completed; artificial tooth cones are inserted into base supports, a position-fixing nail column structure extends from each base support to the corresponding artificial tooth portion, the front face, the back face, the left face and the right face of each position-fixing nail column structure are each provided with a position fixing groove, and the form design of dentitions and the form design of the base supports before CAM are completed; the dentitions and the base supports are respectively processed and formed with a numerical control processing method, and the upper jaw dentition, the lower jaw dentition and the base supports for a complete denture are manufactured; splicing of the upper jaw dentition, the lower jaw dentition and the base supports is artificially completed with an artificer or a doctor. By means of the method, the manufacturing procedure can be simplified, the multi-layer-color attractive requirement of the complete denture can be met, and forming can be accurate.

Description

technical field [0001] The invention relates to an upper and lower jaw dentition and a base for making a complete denture, in particular to a multi-color resin denture dentition base split CNC machining and bonding molding method. 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.

2. Use 3D printing technology to process directly, but there is no directly available product at present

However, none of the above methods can truly reflect the physiology of the artificial dentition of the denture, the CAD results of the personalized occlusal surface, and fail to fully reflect the convenience of digital processing.
