I have been working with inCoris zirconium crowns, abutments, and bridges using the Ivoclar 90 minute rapid firing oven.  The Sirona inFire HTC has a record time of 10 minutes.  This opens new options for chairside InCoris ITS restorative protocols.  I will soon be posting videos with these applications.  

With the expansion of e.max blocks for chairside 3 unit bridges and implant abutments and abutment/crowns, e.max will still my my go to material.  However, materials and processes evolve.  Keep an eye out for inCoris TZI.
