The early computer-aided design/computer-aided manufacturing (CAD/CAM) systems were relied exclusively on subtractive methods. In recent years, additive methods by employing rapid prototyping (RP) have progressed rapidly in various fields of dentistry as they have the potential to overcome known drawbacks of subtractive techniques such as fit problems. RP techniques have been exploited to build complex 3D models in medicine since the 1990s. RP has recently proposed successful applications in various dental fields, such as fabrication of implant surgical guides, frameworks for fixed and removable partial dentures, wax patterns for the dental prosthesis, zirconia prosthesis and molds for metal castings, and maxillofacial prosthesis and finally, complete dentures. This paper aimed to offer a comprehensive literature review of various RP methods, particularly in dentistry, that are expected to bring many improvements to the field. A search was made through MEDLINE database and Google scholar search engine. The keywords; 'rapid prototyping' and 'dentistry' were searched in title/abstract of publications; limited to 2003 to 2013, concerning past decade. The inclusion criterion was the technical researches that predominately included laboratory procedures. The exclusion criterion was meticulous clinical and excessive technical procedures. A total of 106 articles were retrieved, recited by authors and only 50 met the specified inclusion criteria for this review. Selected articles had used rapid prototyping techniques in various fields in dentistry through different techniques. This review depicted the different laboratory procedures employed in this method and confirmed that RP technique have been substantially feasible in dentistry. With advancement in various RP systems, it is possible to benefit from this technique in different dental practices, particularly in implementing dental prostheses for different applications.
早期的计算机辅助设计/计算机辅助制造（CAD/CAM）系统完全依赖于减法制造方法。近年来，采用快速成型（RP）的加法制造方法在牙科的各个领域取得了迅速进展，因为它们有可能克服减法技术的已知缺点，如贴合问题。自20世纪90年代以来，RP技术已被用于医学领域构建复杂的三维模型。RP最近在牙科的各个领域都有成功的应用，如种植手术导板的制作、固定和可摘局部义齿的支架、假牙的蜡型、氧化锆假牙和金属铸件的模具、颌面假体，最后还有全口假牙。本文旨在对各种RP方法，特别是在牙科领域的方法进行全面的文献综述，预计这些方法将给该领域带来许多改进。通过MEDLINE数据库和谷歌学术搜索引擎进行了搜索。在2003年至2013年期间发表的标题/摘要中搜索关键词“快速成型”和“牙科”，涉及过去十年。纳入标准是主要包括实验室程序的技术研究。排除标准是细致的临床和过多的技术程序。共检索到106篇文章，作者进行了筛选，只有50篇符合本综述规定的纳入标准。所选文章通过不同技术在牙科的各个领域使用了快速成型技术。本综述描述了该方法中采用的不同实验室程序，并证实RP技术在牙科中基本可行。随着各种RP系统的进步，有可能在不同的牙科实践中受益于该技术，特别是在为不同应用制作牙科假体方面。
