Macro-Lock® Post Illusion® X-RO® is a fibre-reinforced endodontic post designed for maximum retention with any type of cementation or resin build-up and is enhanced with unique radiopacifiers. The clinical benefits are profound and persuasive.

The post has a tapered apical segment and a parallel coronal section.

In addition, the surface of the post is roughened with controlled specificity to a highly micro-mechanical surface for excellent bonding and long-term retention.

Available in six sizes, the intrinsic post colours match the drill markings and help the clinicians distinguish one size from another. With this Illusion Technology, the colour disappears within seconds at body temperature, but the colour can be reconstituted, if necessary for re-treatment, within seconds. Other features and benefits include:

  • Patented and exclusive X-RO fibres provide unparalleled flexural strength
  • Macro-retentive undercut features on apical and coronal sections provide maximum retention
  • Two flat sides on the coronal section prevent rotation of the core
  • Parallel coronal section offers maximum diameter for strength and surface area for adhesion
  • Patented Illusion colour-change technology eases size identification and removal
  • Superior fatigue resistance and mechanical properties
  • Can be a-traumatically removed in minutes
  • Posts and drills are provided in hygienic "blister" packaging

  2. After crown removal, tooth preparation, and root canal prepared to receive a #1 Macro-Lock X-RO post, the canal is etched for 20 seconds, rinsed, and lightly dried with paper points.

  4. A dual-cured resin cement is placed inside the canal from the bottom to the top avoiding trapping air bubbles.

MacroLockXRO post features Macro Lock

  • Macro-serrations and anti-rotation features interlock with the cement and core material to increase retention.
  • Flexural strength of at least 1800 MPa makes it the strongest fibre post on the market.
  • Intrinsic colour-coding disappears when seated, re-appears on demand if removal ever becomes necessary.
  • Tapered shape enhances adaptation to the root anatomy and conserves dentin.
  • Incorporates colour-coding for easy identification before or after placement – posts match the drills.
  • Atraumatically removable in minutes.
  • Translucency provides esthetics and expedites the dual-cure cementation procedure.
  • Corrosion-free and biocompatible.

RTD Macro-Lock Post Illusion X-RO.

"I have placed over 500 Macro-Lock posts without a single failure. The tapered shape facilitates minimal removal of tooth structure and ensures a minimal amount cement, which minimizes polymerization shrinkage and micro-leakage. Superior physical properties, along with macro and micro-retention, and anti-rotational features make this my post of choice for extensively broken-down teeth."

Dr. Manfred Friedman

"I have used RTD fiber posts since 1997 and do not have cases of breaking or failure in my treatments."
