The On1™ concept: one base that stays on the implant

Placed once, left in place

With the On1™ concept, an On1 Base is placed on the implant at surgery and left there. Healing caps, temporary and final crowns are then attached to the base, so the gum seal is disturbed less often. The On1 Base Xeal was cleared by FDA in 2020.¹
