RTD Fiber Reinforced Endodontic Posts
1988- RTD invented, patented (5,328,372) and commercialized fiber-reinforced endodontic posts. ! Beginning with pre-tensed Carbon Fiber posts, RTD development team has evolved the fiber post through 4 additional “generations”, to include light-transmissive, radiopaque and thermo-chromatic versions of posts. All varieties have proven to have high flexural strength and fatigue resistance.!
Today RTD through its dealer network, offers four variations of posts.
2001-DT Light-Post®- A proprietary “Double-Taper” design, with radiopacity and high translucency, and a micromechanical surface. Over 100 published vi-vitro and clinical studies.
2010 -DT Light-Post Illusion® X-RO® - Same as regular DT Light-Post, but with 50% greater radiopacity, 20% higher strength, due to X-RO fiber, and patented (7,726,971) Illusion Color-On-Command technology.
2007 -Macro-Lock Post®- From the same translucent material as the original DT Light-Post, but with strategic macro-retentions to prevent rotation and dislodgment, when used with any type of cement.
2010 -Macro-Lock Illusion X-RO -Same as regular Macro-Lock, but with 50% greater radiopacity, 20% higher strength, due to X-RO fiber and patented (7,726,971) Illusion Color-On-Command technology.
2006 -Matchpost®- From the same translucent material as the original DT Light-Post, but in a “standard”, narrow, pointed design, offered as the “economy” brand.
2008 -Fibercone® Accessory Post- Extremely narrow posts (one size) used in auxiliary canals, or inside wide, flared canals with full-size post. Improves bond strength, adaptation, fracture resistance, etc.
2008 -2016- Macro-Lock Oval Post- Using RTD patented X-RO fiber and Illusion Color-On-Command technologies, the new design keeps the same apical section/dimensions that correspond with Macro-Lock Drills. However, the post emerges profoundly flared from the round apical section to an oval / parallel coronal section.
Not all styles are available in all countries, and in some countries, different distributors may offer different styles in the same country.
