Cobalt chrome overcast Abutments
download datasheetCobalt chrome overcast abutments respond to demand on a market which increasingly insists on hybrid casting solutions, which are more economical than the gold bases used until some time ago.
These abutments are secondary components used to produce prosthetic artefacts (cemented and/or screwing) on implants, as an alternative to the other prosthetic components available, when the characteristics of dental restoration work must be particularly adapted to the aesthetic and functional specifications of the treated clinical case.
Features and Benefits
Designed with a cobalt-chrome base and a plastic (PMMA) casting component, in two different designs (Indexed and Rotational), permitting single and multiple restorations.
Acting as a mechanical connection between the intraosseous dental implant and the dental crown, they guarantee a high melting point, excellent resistance to corrosion and a high degree of biocompatibility.
They can also be used to compensate differences in axis to create fixed prostheses, screw-in bars, Toronto bars or Toronto Branemark® bars, while continuing to serve their primary function: guarantee precise coupling with the implant.
Bases are available for prosthesis components ø3.25 or ø3.75, for ImpLassic FTP, for ImpLassic HX3 and MUA abutments.
Simple and precise design
Cobalt chrome abutments can be coated directly in ceramic and they are designed by the customer through traditional processing, or through an intraoral scan and designing the shape using dental software.
