Characterisation of geometrical and physical properties of a stainless steel denture framework manufactured by single-point incremental forming

In recent years, numerous scientific and technological innovations have been introduced in the fields of medicine dentistry. The application computer-based engineering techniques has enabled significant improvement design performance biomedical components, including implants prostheses. Innovative flexible manufacturing methods, such as single point incremental forming (SPIF), allow cost-effective production these “custom-made” components. SPIF technology employed to manufacture a metal denture base plate (framework) complete maxillary (upper) replace traditional prosthodontic procedure based on lost-wax technique, which is time-consuming requires much manual work. Stainless steel sheet quality X6Cr17 thickness 0.5 mm was adopted due its biocompatibility, good mechanical properties, reasonable price. process completely designed digital environment with focus achieving high accuracy part followed by experimental verification. For validation, formed compared terms geometry strength reference one fabricated using technique. results obtained confirmed dimensional SPIF-made part. investigations also included analysis thinning, surface roughness, microstructure.
