文题释义:
CAD/CAM技术:是指以计算机作为主要技术手段,采用逆向工程技术测量和扫描各种数字信息和图形信息,以进行产品的设计,再由计算机控制的数控加工设备,如数控铣床等对产品进行加工成型的制作技术。
3D打印技术:由电脑构建出三维数字模型,再将模型分割成众多层面,最后通过3D打印机逐层打印堆积,最终形成实体模型。
数字化印模:是指将光学、电子技术及计算机图像识别和处理技术结合在一起,通过口内光学扫描,将获取的光学信号转换为计算机所能识别的电子信号,将实体物体转换为虚拟数字信息,从而获得三维数字模型。目前临床上常用的数字化印模方法分为直接法和间接法。
 
 
背景:数字化技术在口腔领域应用较为广泛,随着材料学和计算机应用科学的不断发展更新,其便利化、精准化以及在降低医疗成本等方面越来越优越。
目的:综述数字化技术在口腔修复领域的临床应用现状及前景。
方法:以“Digital technology,CAD/CAM technology, Digital impression,Digital dental shade selection,3D printing technology”为英文检索词,以“数字化技术,CAD/CAM,数字化印模,数字化比色,3D打印”为中文检索词,应用计算机在PubMed和中国知识网数据库中检索2012年1月到2017年11月发表的相关文章。纳入与口腔数字化修复相关的研究文献,排除重复性研究,最终纳入68篇文献进行归纳和总结。

结果与结论:数字化修复技术在口腔修复的各个领域已被广泛应用,如单冠、嵌体、贴面、固定桥、可摘局部义齿修复及复杂的全口义齿等制作。相对于传统口腔修复技术,数字化印模、比色及数字化材料设计和加工技术具有更高的时效性、美观性、节约性。随着科学技术的不断发展创新,数字化技术在口腔修复学领域有极大的潜力与未来。

Abstract:

BACKGROUND: Digital technology has been widely used in the oral field. With the continuous development of material science and computer application science, the popularity of this technology has soared owing to its facilitation, precision, and reduction in healthcare costs.

OBJECTIVE: To review the present situation and prospect of digital technology in prosthodontics.
METHODS: A computer-based online research of PubMed and CNKI databases was performed for relevant  articles published from January 2012 to November 2017 using the keywords of “digital technology, CAD/CAM technology, digital impression, digital dental shade selection, 3D printing technology” in English and in Chinese, respectively. After removal of repetitive articles, finally 68 eligible articles were included in result analysis.

RESULTS AND CONCLUSION: Digital technology has been widely used in the oral field, including single crown, inlays, veneer, fixed bridge, removable partial dentures and complex complete denture. Compared to traditional dental restoration methods, this technology has better timeliness, aesthetics, and economy in digital impression, digital dental shade selection, digital design and production. With the continuous development of science and technology, digital technology has great potential and future in dentistry.
