ABSTRACT:
The present invention provides a method for securing a veneer onto a tooth substrate comprising removing enamel in a matrix pattern, to a predetermined depth, from the lingual or buccal surfaces of the tooth, removing the remaining outer enamel layer intermediate the matrix pattern, to the predetermined minimum depth, to provide a first, substantially level excavated enamel surface, further excavating a plurality of compact areas on the first excavated enamel surface to an additional predetermined depth therebelow, but without exposing dentin, to form an indexed enamel surface, taking an impression of such indexed enamel surface, and obtaining from said mold a dental veneer, the dental veneer having a first surface which can mate with such indexed excavated enamel surface, and a second outer surface providing an attractive dentitious appearance; and adhering the indexed veneer surface to the indexed enamel surface, so as to accurately place the veneer on a tooth as an attractive outer labial or buccal surface. Preferably, the indexing grooves are undercut to improve adhesion.
Apparatus is also provided for forming compact indexing excavations within an enamel layer of teeth and for forming undercuts in said excavations.
