This is a highly esthetic, non-metallic restoration that is bonded on the prepared tooth to restore the beauty, strength and function of the tooth.  The procedure is similar to that of a crown, however, due to new techniques of minimal invasiveness, the dentist tries to maintain as much sound tooth structure as possible.   An accurate impression is taken of the tooth, a temporary filling is placed and a porcelain restoration is fabricated by the dental laboratory.  Upon return, the tooth is chemically prepared, and the inlay/onlay is bonded onto the prepared tooth.  The bite is adjusted and polished.  The tooth is once again functionally restored to its almost natural form.
