Unigrip multi-purpose insertion wrench The Unigrip multi-purpose insertion wrench allows gentle and fast implant insertion into the prepared bone bed; as do the other BioniQ insertion wrenches. Moreover, Unigrip allows all conventional instruments designed to fit a handpiece to be used with the BioniQ ratchet. The hexagon marked on the Unigrip shows the position of the anti-rotation element of the implant during the implant insertion.
