Product Description

macrolock-oval-logo.jpg

MACRO-LOCK™ OVAL is a "hybrid" post design for the restoration of wide, flared canals. Featuring colour-on-command illusion technology, advanced X-RO fibre, and compatible with the Macro-Lock drill system, the Macro-Lock Oval simplfies restorations with ovoid canals.

  • The unique oval shape provides anti-rotation benefit, while replacing weaker cement with high strength fibre composite. Oval fibre posts are preferable to circular fibre posts in oval-shaped canals, given the stress distribution at the post - dentin interface.*
  • Macro retentive serrations in the upper 1/3 of the post interlock with the cement and core material to increase retention.
  • The additional bulk or fibre in the middle 1/3 of the post offers maximum strength and frature resistance to help protect the tooth.
  • Passive grooves in the bottom 1/3 of the post lock into the cement in the ROUND apical portion, which is a conservative 0.04 taper.
