Zimmer internal hex with friction-fit:Unmatchable performance by design.• The friction-fit of the 1.5mm deepinternal hex distributes forces deeperwithin the implant, shielding theretention screw from excessive loading. 1• Reduced screw loosening meansgreater patient satisfaction and lesstime spent on complimentaryadjustments and remakes.• The lead-in bevel improves ability toseat the abutment easily and properly.• Unique friction-fit abutments create avirtual “cold weld” with the implantwhen fully seated. This connectionvirtually eliminates rotational micromovement,tipping and vibration-relatedmicromovement of the abutment –leading causes of screw loosening.• The low profile of the internalconnection improves esthetics andallows for a more natural emergenceprofile, especially in esthetic areas.Natural esthetic result due todepth of prosthetic emergence allowedby internal hex connectionMetal exposure due toexcessive abutment cuff heightto accommodate external hexInternal hex with friction-fit –the esthetic solution*Implants highlighted in red indicate cross sections ofboth internal and external connections.External hex – inferior estheticsBulky emergence profile dueto excessive abutment flare toaccommodate external hex
