Macro Lock Post testimonials

What is the Macro Lock Post ?

RTD has used proprietary, radiopaque QUARTZ fibers in its posts since 2000 (with and without intrinsic color-coding). RTD posts with this fiber/resin composition have been successfully evaluated in clinical trials. Moreover, published in vitro studies rate these quartz fiber posts as the highest in terms of radiopacity, flexural strength and fatigue resistance.

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.

With this newest radiopaque, translucent quartz fiber technology, I reach for the Macro-Lock whenever I have minimal useable tooth structure.

Manfred Friedman, Private Practice, Adjunct Professor, Schulich School of Medicine & Dentistry, Univ. of Western Ontario, London, Ontario, Canada

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.

The validity of fiber post has been confirmed by both of the clinical data and experimental studies. I have been using Macro-Lock fiber post for more than three years. The clinic outcome is excellent. Meanwhile, the mechanical properties of Macro-Lock fiber post have been tested in our studies, experimental or numerical analysis. The quality of Macro-Lock fiber post is outstanding.

Sandra Costa Zamboni, Dept. of Dental Materials and Prosthodontics, São Paulo State University at São José dos Campos, Brazil

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

Nicolas Cheleux, Private Practice. Former Assistante of Toulouse University, France

I have used RTD fiber posts regularly for more than 10 years and I have had the opportunity to observe the constant improvement with each generation of fiber post. The replacement of the carbon fibers with quartz fibers has dramatically improved the bio mechanical properties, with a modulus of elasticity closer to the dentin, the adhesion with all of the bonding systems as well as the optical properties of the post, to optimize the aesthetics of the final restoration.

Christine Berthold, Dept. of Endodontics, Univ. of British Columbia, Canada, Department for Operative Dentistry and Periodontology, Univ. Erlangen, Germany

I have used these posts clinically with satisfaction, and appreciate their properties and their quality.

Gilberto Henostrosa, Chief; Section for Operative Dentistry & Biomaterials, University Peruana Cayetano Heredia, Peru

I have used RTD fiber posts clinically for over 20 years, since the early carbon fiber composition, with satisfying clinical results. The current generation of Macro-Lock posts seems to combine RTD’s best work as to a conservative, tapered shape, maximum bulk and strength in the most critical areas, and adequate retention mechanisms inside and outside of the tooth. The radiopaque X-RO fiber and Illusion color-change technologies make these posts even more appealing.

Alejandro Bertoldi Hepburn, Del Desarrollo Dental School Concepción, Chile

We have evaluated several generations of RTD fiber posts in the clinic over hundred of patients in very varying situations. They have exceeded our expectations !
