<p>The invention provides a method for securing a veneer onto a tooth comprising removing enamel in a matrix pattern, to a predetermined depth, from the lingual or buccal surfaces 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 (103) 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 a mold a dental veneer having a first surface which mates with such indexed surface, and a second outer surface and adhering the indexed veneer surface to the indexing grooves are undercut to improve adhesion. Apparatus (40, 51) provided for forming compact indexing excavations within an enamel layer and for forming undercuts in said excavations.</p> |
