Case review: CEREC porcelain onlay restoration, May 9, 2012

 The 60 year old patient complained of a "broken tooth."  Examination showed a defective filling with recurrent carious lesion extending to all four surfaces (FDOL) of the tooth.  Because the extensive of the decay, the strength of the tooth was compromised and the onlay restoration was recommended.

Preparation of the onlay was done in the patient mouth.



The onlay data was being prepared by the CEREC program



Computer generated a drawing of the onlay 3-D shape



The onlay was ready to be fabricated by the CEREC milling chamber as the CEREC program calculated how much time required to mill out the onlay.

  1. Tooth restoration is generally necessary for a couple of factors which are either cavities also called caries, or trauma to a tooth through an accident or even injuries. You will discover a variety of methods for addressing regenerative dentistry the most typical being a filling for any cavity triggered through caries.
