Abstract:
Objective:To evaluate the fit of titanium alloy removable partial denture framework fabricated by selective laser melting(SLM) technique.Methods:7 Kennedy Ⅲ Ti-6Al-4V removable titanium alloy partial denture frameworks were fabricated by SLM technology.An optical scanner was used to scan the gypsum model adhered with the silicone rubber film obtained by the impression method before and after removal of the film.Geomagic Qualify 2013 software was used to analyze the gap between the model and the tissue surface of the major connector of the framework,the fit of the frame work was evaluated.Results:The overall 3D deviation between the titanium alloy frameworks and the gypsum model was (0.221 9±0.07) mm.Conclusion:The fit of the titanium alloy removable partial denture framework made by SLM technology can basically met the clinical requirements.
