摘要:

文题释义:
熔融沉积成型:是将热熔性材料加工成丝状,经过送丝机构到达热熔喷嘴上,之后热熔性材料被加热装置加热融化,沿着打印机已经设定好的路径进行运动,同时加热融化的丝状材料在成型平台上凝固成型,层层粘接堆积,最终形成产品模型。
光固化立体成型技术:能够在微米级的精细分辨率下制造高表面质量的零件,其成型过程就是树脂材料进行光固化聚合的过程,一般是以点成线、以线成面,然后成型平台根据打印参数决定的打印层厚进行升降。

背景:对于牙齿缺损或缺失的病例,需通过个性化制作修复物达到治疗目的。传统的制作工艺耗时长、费用高、精准度差。3D打印技术引入牙科制造后,能一定程度提高制作效率和品质。

目的:介绍 3D 打印技术在牙科制造中的应用现状,讨论目前应用中存在的技术瓶颈,展望未来3D打印技术在牙科制造应用的发展方向。

方法:作者以“3D printing,metal implant,dental manufacturing,dental restorations,3D 打印,骨缺损,金属内植物,牙科制造,牙科修复”等为关键词,检索1980至2019年期间的Web of Science、万方、CNKI 数据库中的相关文献。初检文章 261 篇,筛选后对60篇文章进行参考总结。

结果与结论:3D 打印牙模、数字化种植导板、蜡型等已在牙科制造中得到应用和推广,3D打印技术在牙科制造已得到较广泛的应用,使用最为广泛的6种工艺分别是树脂光固化成型、叠层实体制造、熔融沉积成型、选择性激光烧结、选择性激光熔化、立体喷墨技术。目前3D打印技术在牙科制造领域的应用存在着一定的技术瓶颈,突破技术瓶颈后,3D打印技术在未来的牙科制造领域将能发挥更大作用。

Abstract:

BACKGROUND: In the case of tooth defect or missing, the treatment should be achieved by making a personalized prosthesis. Traditional manufacturing process is time-consuming, costly and accurate. After the introduction of 3D printing technology into dental manufacture, the manufacturing efficiency and quality can be improved to a certain extent.

OBJECTIVE: To introduce the application of 3D printing technology in dental manufacture, discuss the bottleneck in recent application, and guide the development of 3D printing technology in dental manufacture.

METHODS: The authors used the search times "3D printing, metal implant, dental manufacturing, dental restorations” to search Web of Science, Wanfang, CNKI databases in English and Chinese separately to search papers published during 1980-2019. 261 papers were preliminarily retrieved and 60 of them were included in the final analysis.

RESULTS AND CONCLUSION: 3D printing dental mold, digital implant guide plate and wax pattern have been widely used in dental manufacture. 3D printing technology has been widely used in dental manufacture. The most widely used six processes are stereo lithography appearance, laminated object manufacturing, fused deposition modeling, selective laser sintering, selective laser melting, and inkjet printing. There are some technical bottlenecks in the application of 3D printing technology in the field of dental manufacturing. After breaking through technology bottlenecks, 3D printing will be more useful in the field of dental manufacturing in the future. 

Key words: 3D printing technology, dental manufacturing, dental restorations, stereo lithography appearance, laminated object manufacturing, fused deposition modeling, selective laser sintering, selective laser melting, inkjet printing
