Medical costs are increasing significantly and the development of advanced and inexpensive medical instruments by applying the technology of plastic processing has been required. In this study, mass-production technology at a low production cost for medical and dental precision instruments such as guide wire and orthodontic wire, a stent, and a screw for allergy-free implant of a teeth, for which considerations to biocompatibility, shortening of postoperative healing time and pain alleviation after surgery must be paid, were explored. Using wires of biocompatible and functional materials such as purity titanium, titanium alloy, shape-memory alloy, and magnesium alloy, downsizing of a product into a micro device and production of a human-body-friendly functional product are explored by applying drawing method and rolling method. Inexpensive production conditions for human body-friendly medical micro parts which are made by the best use of drawing characteristic have become clear.
