ABSTRACT:
A crown and/or a replacement tooth and a method of in situ production thereof by grinding and shaping a tooth to form a prepared tooth; filling a transparent shell tooth form with a light setting resin; disposing the filled shell tooth form onto the prepared tooth; illuminating the filled transparent shell tooth form to set the light setting resin and bond the resin to the shell tooth form; and shaping and polishing the set resin in situ to form a crown. A set of shell tooth forms is provided which are formed from a light setting resin chemically compatible with the resin used to fill the form in order that bonding occurs therebetween. This feature enables the products of a replacement tooth formed in situ without the necessity of shell tooth form removal as heretofore required.
