Dental restoration cad/cam/slm-3d printing composite method

Abstract

Disclosed is a CAD / CAM / SLM-3D combined printing method for dental restorations. A CAD / CAM / SLM-3D combined printing system, constituted by an optical scanning measurement instrument or a contact scanning measurement instrument, computer-aided design software for dental restorations, a miniaturized metal 3D printer, and a numerically controlled milling machine, is used to prepare a metal restoration, combining the existing dental CAD / CAM system with a metal 3D printing technique to combine the respective numerically controlled processing methods thereof so as to maximize the effects. The method can improve the automatic production efficiency of metal dental restorations, especially complex metal dental restorations, and eliminate the cumbersome procedures in the traditional manual manufacture for dental restorations. Thus the method improves the manufacturing quality and stability of restorations, achieving the purpose of rapid, accurate and personalized manufacturing, and better satisfying the urgent requirements of patients with tooth loss.

Description

technical field [0001] The invention relates to an automatic processing method for oral restorations, in particular to a CAD / CAM / SLM-3D printing composite method for oral restorations. Long, the organic combination of their respective numerical control processing methods, the effect to the extreme, to achieve the goal of fast, accurate and personalized production of oral restorations. Background technique [0002] Computer-aided design (CAD for short) and computer-aided manufacture (CAM for short) technology integrate mathematics, optics, electronics, computer image recognition and processing, automatic control and automatic processing and other multi-disciplinary knowledge and technology. It was widely used in industrial automation and aerospace fields in the 1970s. In 1983, the first dental CAD / CAM system prototype developed by France Duret came out in France; at the International Dental Academic Conference held in France in 1985, Professor Duret used this equipment to pr...

Problems solved by technology

In 2008 and 2009, Gao Bo of the Fourth Military Medical University of the Chinese People's Liberation Army successively published the treatises on laser rapid prototyping for the manufacture of maxillary pure titanium substrates for complete dentures: LasersMedSci (2010) 25: 309–315; RapidPrototypingJournalVolume15, Number2, 2009, 133–136 , and its suitability has been studied, and the clinical test results show that its production accuracy needs to be improved

[0030] 3. Limitation and development direction of traditional CAD / CAM in clinical application

However, there are still the following problems in the clinical application process: At present, CAD / CAM systems are mainly used in the field of fixed restorations, but not in removable partial dentures and complete dentures. The main reason is the inherent limitations of CAD / CAM systems in cutting. It not only causes a waste of materials, but also makes the types of prosthetics produced single, and composite prosthetics cannot be machined.
