CorPOSIT

Consultants’ Comments

  • “It cuts more like dentin than any other core material I’ve used.”
  • “Optimal consistency that is ideal for core build-ups and post cementation.”
  • “It’s about as perfect a material as I have used in 30 years of practice.”
  • “It dispenses easily, in a controlled manner, and it’s easy to dispense down the canal for the post.”“A slight increase in flowability would really help.”
  • “Sometimes the delivery tip leaked material.”
  • “The dispensing tips are hard to use in tight areas.”

Clinical Tips

  • As with most core materials, dispense with the tip in the material.
  • The fine tips are necessary to avoid voids, but the composite is very difficult to express through the small tube. Cut the tip for easier extrusion.
  • Place the composite in increments.
  • The material is hard once set. Use a brand new diamond bur for final tooth preparation.

Evaluation Highlights

  • CorPOSIT was evaluated by 26 consultants, with an average of 16 uses per consultant.
  • This is a very easy and predictable material to use clinically.
  • Easy to handle, adaptable, and easy to trim.
  • The finish is very smooth.
  • Very radiopaque.
  • Adapts very well around pins and posts, and it doesn’t slump.
  • Flows well into areas with undercuts.

Description

CorPOSIT is a dual-cured, radiopaque flowable composite. It offers a working time of 90 seconds from the start of the mix in self-cure mode, and has a 40-second light-cure and 3-minute self-cure. The manufacturer has reported a compressive strength of 342 MPa, bond strength to dentin of 26 MPa, and a bond strength to Glassix+ fiber posts of 34 MPa when used with Shotbond adhesive. CorPOSIT is available packaged with two syringes (6 g each), 10 mixing tips and 10 intra-oral tips.

Indications

  • Core build-up
  • Cementation of endodontic posts Unique Features
  • CorPOSIT is designed to have optimal flow properties and to cut like dentin once set.
  • It can be used both for core build-ups and post cementation.
  • The intra-oral tip is designed to offer void-free and precise application.
