Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
60 words
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.
Claim 2
Dependent Claim
60 words
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.
Claim 3
Dependent Claim
48 words
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.
Claim 4
Dependent Claim
48 words
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.
Claim 5
Dependent Claim
23 words
The shell tooth form according to claim 2 wherein said photopolymerized material shaped in the form of a tooth is of unitary construction.
Claim 6
Dependent Claim
48 words
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.
Claim 7
Dependent Claim
48 words
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.
Claim 8
Dependent Claim
19 words
The permanent dental crown according to claim 4 wherein the photopolymerized material and photopolymerized resin comprise the same compound.
Claim 9
Dependent Claim
23 words
The permanent dental crown according to claim 5 further comprises additional photopolymerized resin disposed on an exterior surface of said transparent photopolymerized material.
Claim 10
Dependent Claim
22 words
The permanent dental crown according to claim 6 wherein the photopolymerized resin and the additional photopolymerized resin are of the same color.
Claim 11
Dependent Claim
22 words
The permanent dental crown according to claim 6 wherein the photopolymerized resin and the addition of photopolymerized resin are of different colors.
Claim 12
Dependent Claim
59 words
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.
Claim 13
Dependent Claim
59 words
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.
Claim 14
Dependent Claim
18 words
The system according to claim 9 wherein the photopolymerized material and the photopolymerizable resin comprise the same compound.
