Digital Dentistry

I scan digital impressions of teeth, computer design the crowns, create an STL file, and 3D print out porcelain/zirconia crowns with a CAD-CAM milling machine, that fit perfectly and look beautiful.

Implant and crown case of the day

On this patient I noticed decay under two 20 year old crowns on teeth #30 and 31.  Removal of the old crowns revealed tooth #30 with deep decay sub-gingival into the root furcation. This tooth was non-restorable.  I recommended extraction and an implant. For tooth #31, I was able to clean out the decay and do a crown build-up and make her a new crown.

The first x-ray above shows my initial try-in with a gap between the implant crown and implant. The crown would not fully seat, so I re-did the implant crown. The second x-ray, after re-doing the implant crown, shows a perfect fit!!! Both the implant crowns #30 and #31 fit and look beautiful.

Crown case of the day

This patient wanted me to give him a beautiful white smile. I placed porcelain crowns on his upper front teeth 3 years ago and he returned now to do the lower teeth. Here are the pictures:

Crown case of the day

This patient was hit in the mouth with a tennis racquet and broke his front tooth. The tooth also required a root canal, and periodontal crown lengthening surgery. I placed a temporary crown on the tooth for 2 months while the gums healed and did a computerized custom shade match to obtain a perfect color match.
