Dental devicemaker ZimVie, which first launched three years ago as a spinout of Zimmer Biomet’s spine and dental units, is to be acquired by investment firm ArchiMed through a $730m deal that aims to close before the end of the year. ZimVie, after selling off its portfolio of spinal implants and fixation systems to H.I.G. Capital for $375m, has a catalog of dental implants, biomaterial grafts and digital scanning hardware.
