Mass-production technology of guide wire, stent and implant dentistry with human boby-friendly

医疗费用正在显著增加，并且已经需要通过应用塑料加工技术来开发先进且廉价的医疗器械。在本研究中，探索了医疗和牙科精密器械的低生产成本的大规模生产技术，如导丝和正畸丝，支架和用于无过敏性牙齿植入的螺钉，为此必须考虑生物相容性，缩短术后愈合时间和减轻术后疼痛。使用生物相容性和功能性材料（例如纯钛、钛合金、形状记忆合金和镁合金）的线材，通过应用拉伸方法和轧制方法探索将产品缩小为微型装置并生产对人体友好的功能性产品。充分利用拉深成形的特点，以低廉的成本制造出对人体友好的医用微型零件的条件已经明确。

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.
