In short
  • Used on abutments such as On1™ Base Xeal, Multi-unit Abutment Xeal and N1 Base Xeal.12
  • Intended for the soft-tissue (gum) zone.1
  • Patient-level long-term data are limited.

Why the gum zone matters

A tight, healthy seal of gum around the abutment helps protect the bone underneath. Good cleaning and regular professional check-ups remain essential whatever surface is used.
