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.
Claims10
A transparent shell tooth form made by:
- coating a tooth form with a light setting resin that is transparent when set;
- illuminating the light setting resin on said tooth form to cause setting of the light setting resin and formation of a shell tooth form on said tooth form;
- and
- removing the set shell tooth form from the tooth form.
A shell tooth form comprising:
- a transparent photopolymerized material shaped in the form of a tooth and having means, defining a hollow center, for enabling filling of the tooth form with a photopolymerizable resin and for enabling light setting of the photopolymerizable resin through the transparent photopolymerized material.
A permanent dental crown comprising:
- a transparent photopolymerized material shaped in the form of a permanent dental crown and including means for defining a hollow center;
- and
- a photopolymerized resin disposed in said hollow center, said photopolymerized resin being photopolymerized through the transparent photopolymerized material and bonded thereto.
A shell tooth system for replacement teeth and permanent dental crowns, said system comprising:
- a transparent photopolymerized material shaped in the form of a tooth and including means for defining a hollow center;
- and
- photopolymerizable resin means for filling said hollow center and bonding to said transparent photopolymerized material upon photopolymerization of the photopolymerizable resin through the photopolymerized material.
