“…Among all Chinese and international publications, we found that Chinese investigators have particularly contributed to CAD-CAM application, 13 computer-assisted manufacture of facial prosthesis, 14 and 3D-assisted dental education 15 and dentist-patient interaction. 8 For international publications, Chinese investigators in DI and d-IT research were mainly composed of dentists and mechanical engineers.…”

Background/purpose: Dental informatics (DI) is a new emerging interdiscipline for medical informatics (MI) and general dentistry, and dental information technology (d-IT) is a parallel research field. The purpose of this study was to investigate the current situation of DI and d-IT in China, evaluate the achievements, analyze the weakness, and anticipate the future development. Materials and methods: Publications about DI and d-IT in English and Chinese journals by international and Chinese researchers were searched through literature reviews. The funds supporting DI and d-IT in China were manually searched. DI and d-IT education in China was analyzed by website search and telephone interview. Results: The investigation indicated that China started research in DI and d-IT fields from the late 1970s, but the development has become more rapid in the last 10 years. Both Chinese and international publications have increased sharply within the last decade. The Chinese government kept a stable increasing investment in DI and d-IT scientific projects and Chinese researchers made influential achievements in certain fields of DI and d-IT, such as computer-aided design and computer-aided manufacturing (CAD-CAM) development and application, computer-assisted manufacture of facial prosthesis, and three-dimensional (3D)-assisted dental education. Conclusion: DI and d-IT have developed rapidly in China in recent years. However, there are some problems which remain to be resolved.

The wax sculpting of a maxillofacial prosthesis is challenging, time-consuming, and requires great skill. Rapid prototyping (RP) systems allow these hurdles to be overcome by enabling the creation of a customized 3D model of the desired prosthesis. Geomagic and Mimics are the most suitable software programs with which to design such prostheses. However, due to the high cost of these applications and the special training required to operate them, they are not widely used. Additionally, ill-fitting margins and other discrepancies in the final finished products of RP systems are also inevitable. Therefore, this process makes further treatment planning difficult for the maxillofacial prosthodontist. Here, we report the case of a 62-year-old woman who attended our clinic. Initially, she had presented with a right facial defect. This was later diagnosed as a squamous cell carcinoma and resected. The aim of this report is to describe a new technique for the 3D printing of facial prostheses which involves the combined use of open-source software, an RP system, and conventional methods of fabrication. The 3D design obtained was used to fabricate a maxillofacial prosthesis to restore the defect. The patient was happy with the esthetic outcome. This approach is relatively easy and cheap, does not require a high degree of non-medical training, and is beneficial in terms of clinical outcome.

“…The term 'technically able to be printed on current printers' refers to the ability to meet material property, accuracy, size and resolution requirements of the printed part and that the overhangs necessary to print the part are manageable. Examples of Class 1 objects are facial prosthetics, which using 3-D printing are already being investigated for the developed world (Feng, et al, 2010) and limb prostheses. Prostheses are typically very expensive, and widespread issues with availability and distribution (Beshai & Bryant, 2003) causes poor access in developing countries (Borg, 2009).…”

The technological evolution of the 3-D printer, widespread internet access and inexpensive computing has made a new means of open design capable of accelerating self-directed sustainable development. This study critically examines how open source 3-D printers, such as the RepRap and Fab@home, enable the use of designs in the public domain to fabricate open source appropriate technology (OSAT), which are easily and economically made from readily available resources by local communities to meet their needs. The current capabilities of open source 3-D printers is reviewed and a new classification scheme is proposed for OSATs that are technically feasible and economically viable for production. Then, a methodology for quantifying the properties of printed parts and a research trajectory is outlined to extend the existing technology to provide complete village-level fabrication of OSATs. Finally, conclusions are drawn on the potential for open source 3-D printers to assist in driving sustainable development.
