All Ceramic CEREC® Restorations
CEREC® technology allows Meetinghouse Dental Care to design and mill solid-block ceramic crowns and onlays in a single visit. No need for impressions, temporaries, delivery visits or a second time getting numb! Ceramic restorations (crowns and onlays) are required in cases where composite fillings will not hold up long term (mainly when there is less than 50% of the tooth structure is remaining after preparation is complete).
How does CEREC® CAD/CAM work?
CEREC®'s bluecam LED camera captures an optical impression of your damaged tooth. The camera communicates the optical impression to 3D CAD (Computer Aided Design) software that designs a digital restoration to the exact contours of the tooth to be restored. The data is sent to a milling chamber and the CAM (Computer Aided Manufacturing) technology automatically mills the crown or onlay with two high-speed diamond burs while you watch!
CEREC® crowns and onlays are:
- highly biocompatible
Bisphenol A and B free
Crowns vs Onlays
Meetinghouse Dental Care creates both crowns and onlays in office from a solid, all ceramic block. Whenever possible, onlays are preferred over full coverage crowns due to the preservation of remaining healthy tooth structure. Less drilling is always favorable to maintain a healthy nerve. Onlays are just as strong as crowns. CEREC®'s decades of clinical research and documentation indicate that 84.5% of all CEREC® restorations are still viable eighteen plus years after original placement in the mouth. Some clinicians predict that CEREC® crowns and onlays - milled from solid-block ceramic rather than heat processed and layered over metal alloys in the lab - may last many patients a lifetime (longevity represents less trauma to the nerve of the tooth over the lifespan of that tooth).
CEREC® restorations exhibit the same refractive qualities as natural tooth enamel for precise color match and the same thermal qualities as natural tooth enamel for ideal expansion and contraction. Their similarity to natural tooth enamel eliminates the wearing of opposing teeth, a common problem with lab-fabricated porcelain-fused-to-metal crowns.
Finally, with CEREC®, there is no metal substructure; the oral galvanic current (see our section on oral galvanism) generated by lab-fabricated porcelain-fused-to-metal crowns is completely eliminated.
