Photosensitive resin used for 3D printing and its application in dentistry / 中国组织工程研究

ABSTRACT

BACKGROUND:Nowadays,digitalization has become a major trend in the field of dentistry.It is highly important to apply 3D printing technology with the material of photosensitive resin to orthodontics,prosthodontics and so on.OBJECTIVE:To review the composition of photosensitive resin for 3D printing and its main commercial series,and to discuss about applications and prospects of photosensitive resin in the field of dentistry.METHODS:Using "3D printing,digitalization,photosensitive resin,dentistry" as key words in English and Chinese,the authors seareched the database PubMed and CNKI,respectively,for articles addressing the development of 3D printing technology,classification and composition of photosensitive resin as well as the progress and application of photosensitive resin in the field of dentistry over the past 15 years (1991-2016).RESULTS AND CONCLUSION:Because of achieving the visualization of data,having advantages such as personalized design printing,fast small batch production,efficient and free molding manufacturing and being easy to manufacture complex modeling products,3D printing technology has been developed rapidly in various areas.Light-curing rapid prototyping technology (Stereo Lithigraphy Apparatus,SLA),based on photosensitive resin,is one of the most widely used technological processes of 3D printing.Photosensitive resin for 3D printing can be classified by composition and the main commercial series.At present,the development of photosensitive resin for 3D printing meets the demand of personalized design in the field of dentistry.It has been developed rapidly in orthodontics,prosthodontics,oral implantology,and oral internal medicine.It can be used in fixed denture,implanted surgical guide,base for removable denture and fused model manufacture.With the continuous expansion of the types of materials and improvement of material performance,digital dentistry will become a major trend in the future.
