Dental prosthesis CAD/CAM/SLM-3D printing compound method

Abstract

The invention discloses a novel dental prosthesis CAD / CAM / SLM-3D printing compound method. The method comprises the steps that a CAD / CAM / SLM-3D printing compound system which is composed of an optical scanning measuring instrument or a contact type scanning measuring instrument, computer-aided design software of a dental prosthesis, a miniaturized metal 3D printer and a numerical control milling machine is adopted to prepare a metal prosthesis, an existing dental CAD / CAM system is combined with a metal 3D printing technology, respective numerical control machining methods are organically combined, and the effect is extremely achieved. The automated production efficiency of the dental metal prosthesis, especially the complex dental metal prosthesis is greatly improved, traditional cumbersome processes for manually making a dental prosthesis are omitted, the making quality and stability of the prosthesis are improved, the purpose of rapid, accurate and personalized making is achieved, and the urgent needs of patients missing teeth are well met.

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.
