Abstract An integrated method of reverse engineering and rapid prototyping technology to manufacture complete denture was presented in this paper. Firstly, geometrical surfaces of complete denture were measured by three-dimensional scanner and their point clouds were obtained. Then the point clouds de-noising processing was performed,data was filtered and reduced, the missing data was repaired and triangular surfaces splicing was realized in Geomagic software. 3D model of complete denture was reconstructed in Pro/E software, and the STL file was generated. Finally, the entity model was manufactured by rapid prototyping machine. Through this process the entity model of running-in-period complete denture was manufactured, which can reduce denture repairing time and contribute to health and medical research.

226.1 Introduction With the progress of science and technology (especially material science and computer aided technology), molding materials and rapid prototyping technology (such as 3D technology) are also constantly improved in the medical application. According to news, recently, a patient was accepted a successful pioneering surgery in the United States. The surgery used 3D-printing skull to replace 75 % of D. Li X. Feng P. Liao H. Ni Y. Zhou M.

the patient’s own skulls. In the manufacturing process of the skull, the researchers first scanned the head of the patient, then they used 3D-printing technology to print out skulls for transplantation. Traditional cranial molding materials are: organic glass, silicon rubber, steel plates, Medpor (linear high-density polyethylene material), hydroxyapatite, titanium alloy, etc. [1, 2]. They used PEKK (polyetherketoneketone) as the print material. The customized implants for patients could be completed within 2 weeks, which have a significant impact in the field of plastic surgery. Reverse engineering is to transform the product model or physical model into a design model and conceptual model, then to anatomy and deepen the existing products and to create again [3]. Reverse engineering application range is very wide in the aerospace, automotive, household appliances, computing machines, machinery, mould, entertainment industries and other industries. In addition, there also has a wide application in the replication of archaeological cultural relics and the body organs, bones and jo
