Abstract
Single point incremental forming (SPIF) is a modern, dieless sheet metal forming technique applied mostly for small batch and custom-made products of various shapes and dimensions. Compared to conventional sheet processes it offers many advantages, especially in terms of flexibility and material formability.
In the field of dentistry, there is a natural need for tailored production i.e. personalized devices that are custom made for the patient, area in which SPIF is highly promising. In association with computer (CAD, CAM) and medical imaging technique (MRI, CT), this technology enables higher level of both aesthetic and functional characteristic of the product, in relation to traditional manufacturing methods.
In the paper presented, SPIF technology was applied for manufacturing of a denture base (framework) of a complete denture. The research included two base materials: low carbon steel EN DC04 and stainless steel EN X6Cr17. The main objective of the research was to compare the geometry of the denture base shaped by SPIF, with an existing denture base made by the lost wax technique.
