D.T. Light-Post® Illusion™ X-RO™ is RTD’s new fiber post innovation. It combines our (patent pending) color-on-demand Illusion technology with an exclusive, extra radiopaque (patent pending) fiber; developed by RTD over 5 years’ time, specifically for this clinical application. These combined technologies meet in our famous Double-Taper (D.T.) shape. It is available in 4 size-related colors.
• Radiopacity of the X-RO is 50% greater than previous generations of D.T. Light-Posts, to reach 340% of Aluminum equivalent (ISO Standard #4049). The radiopacity of the post itself varies from 360 % (D.T. size 0.5) to 730 % (D.T. size 3).
• X-RO fibers also utilize a proprietary silane coupling agent that increases the bond between the fiber and the epoxy matrix. The new fiber improves Flexural Strength* by at least 200MPa, and maintains high fatigue resistance** (10 000 000 Cycles with a load of 100 Newtons without breaking).
MECHANICAL PROPERTIES
Flexural strength* (ISO 14125): 1800-2000 MPa
Interlaminate Shear Strength* (ISO 14130): 65-70 MPa
Radiopacity** (ISO 4049): 3mm Al equivalent
Fatigue strength** (RTD’s protocol): > 10 millions cycles without breaking
FEATURES AND BENEFITS
• Proprietary silane coupling agent on exclusive X-RO fibers: Flexural strength is increased to 1800 MPa*, the highest in the market
• New X-RO fiber increases radiopacity of the post to 300% of Aluminum**: Easier diagnostics. Highest radiopacity on the market
• Increased surface roughness during manufacture: NO NEED for chairside silane or surface treatments, and push-out bond strength is increased by 33%***
• Intrinsic Illusion technology color-coding: Easy post size and brand identification; colors matched with corresponding drills
• Color disappears when seated; becomes translucent: Aesthetic; use under any composite, inlay or crown
• Color re-appears on demand: Removal, if ever necessary, is easier
• Double taper or double conicity: Optimal adaptation and conservative preparation
• High Tensile, Shear strength & proven Fatigue Resistance: Durability and clinical success
• Translucent after clinical placement: Aesthetics and light transmission
• Passed ISO Cytotoxicity, intradermal, systemic toxicity, genotoxicity and hypersensitivity testing: Ensures complete biocompatibility and safety. Fiber posts cannot corrode like stainless steel & base alloys
• Elastic Modulus (20GPa at 30 deg.) similar to dentin: Helps prevent root fracture
*ISO #14125, ** ISO #4049, *** In-house test. Data on file.
ADVANTAGES
• No clinical root fractures, due to elastic modulus close to dentin
• Ideal double tapered designs means optimal adaptation, conservative preparation
• Retention equal to, or better than, metal and other fiber posts
• Performance is prove in clinical trials
• Atraumatically removable in minutes
