Why place a round post in an oval space?

A SUCCESSFUL PRODUCT WITH A REVOLUTIONARY NEW ANGLEoval display

RTD announces a new "hybrid post" design for the restoration of wide, flared canals. Keeping the Illusion color-on-command technology, advanced X-RO fiber, and the Macro-Lock drill  system, the new Macro-Lock Oval simplifies these restorations: round and slightly tapered at the apical end, it flares profoundly and beocmes oval.

 

 

ULTIMATE RADIOPACITY

Screen Shot 2016-02-08 at 10.57.53 AMposition display

The exclusive, patented X-RO fibers produced unsurpassed radiopacity among fiber posts in the market today. The additional thickness produced by the flared shape improves visibility even more.


PATENTED ILLUSION Color-On-Command TECHNOLOGY  Sizes.001

  > Color-coding for easy identification; posts colors match the drills
  > Four color-coded sizes match the existing Macro-Lock finishing drills
  > Intrinsic color coding disappears when sealed, re-appears on demand if  removal ever becomes necessary

 

 

Oval-Post-Red

> Macro-Lock Oval has the widest flare available in a prefabricated fiber post
> The unique oval shape provides anti-rotation benefit, while replacing weaker cement with high-strength factory produced fiber reinforced composite
> They can be slightly contoured and customized, if necessary, with a common flexible disk
> The additional bulk of fibers in this critical "cervical" zone offers maximum strength and fracture resistance to help protect the tooth
> Oval fiber posts are preferable to circular fiber posts in oval-shaped canals, given the stress distribution at the post - dentin interface
> Macro-retentive serrations interlock with the current & core material to increase retetention
> Passive grooves lock into the cement in the ROUND apical portion; a conservative 0.04 taper

Other Benefits

  • Benefits

  • As always, the elastic modulus is close to dentin (15GPa @ 300); producing no clinical root fracture
  • High translucency provides aesthetics, and expedite the dual cure cementation procedure
  • Corrosion-free and biocompatible, X-RO has passed the common test of cytotoxicity, but also intradermal reativity, systemic toxicity, genotoxicity and hypersensitivity, in order to ensure complete biocompatibility and safety
  • Like all of our fiber posts, these are atraumatically removable in minutes
