Macro-Lock Post®
- Patented Quartz fibers provide high Flexural Strength, Fatigue Resistance and radiopacity
- Neutral color offers aesthetics and TWICE the amount of light transmission as its X-RO counterpart
- Macro-retentive undercut features on apical and coronal sections for maximum retention.
- Two flat sides on coronal section to prevent rotation of core.
- Parallel coronal section offers maximum diameter for strength, surface area for adhesion
- Push-out Adhesion to dentin confirmed superior to smooth posts of the same shape
- Can be a-traumatically removed in minutes.
- Posts and drills are provided in hygienic "blister" packaging.
More information
The Macro-Lock Post, is an advanced fiber post designed for maximum retention, with any type of cementation or resin build-up. 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 post is designed with a series of serrations and passive threading cut into the surface, to provide self-retention regardless of the cementation media used. It is provided for dentists not completely comfortable with the total-etch / moist bonding materials & techniques, or dentists who would prefer to use glass ionomer cements with resin core materials. Independent research shows retentive strength previously unattained.
