This is my first VITA Enamic crown.  It polishes more like a traditional ceramic.  Mill and margin is excellent.  No chipping even with a thin margin, so no need to bulk margin prior to mill.  Post-mill finishing steps included occlusal refinement with 35 carbide inverter cone, Dimond Twist (Preimer) fibra wheel for pre-polish and then stiff polishing brush with F-Diashine.  Using a stiff polishing brush with Diashine, slowRead more

CEREC 4.0 has expanded the CAD/CAM industry.  With the combo of e.max, I am routinely preparing, scanning, and milling flawless feather margins…WOW.  The 4.0/MC XL machining precision is phenomenal. With 4.0, I now finally have my fully integrated restorative command center to control my clinical theater.  Thanks Sirona and Ivoclar for teaming up and providing a restorative dream!  The presented veneer case conveys where we have come with the current systemRead more

I have done a number e.max implant abutment-crowns and they are working very well.  I use them in the posterior region when the implant alignment provides a screw access retention option.  A Sirona TiBase is seated and then scanned.  The CEREC 4.0 scan and mill algorithms are precise enough to generate a tight/snug fit.  TiBase anti-rotational factors are increased with additional preparation to the TiBaseRead more

Completed this CEREC LAVA Ultimate onlay/inlay case this afternoon.  Tooth 30 had cracked tooth symptom and major cold sensitivity.  Horizontal/stained fracture lines at prep axial/pulpal floor distal buccal and lingual cusps.  With a solid rim of 1.0-1.5 mm of enamel for retentive bond, Lava adhesively bonded restorations will recapture function requirements for this case.  Interesting enough, patient was ecstatic about cold symptoms completely gone afterRead more
