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.

84 words
A method of making a permanent crown for a tooth comprising: grinding and shaping the 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 therein and bond the light setting resin to the shell tooth form and prepared tooth; and shaping and polishing the shell tooth form in situ to form a crown.
Claim 2
Independent Claim
84 words
A method of making a permanent crown for a tooth comprising: grinding and shaping the 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 therein and bond the light setting resin to the shell tooth form and prepared tooth; and shaping and polishing the shell tooth form in situ to form a crown.
Claim 3
Dependent Claim
38 words
The method of claim 1 further comprising the steps of adding light setting resin to an exterior of the shell tooth form and illuminating the added light setting resin to bond it to the shell tooth form exterior.
Claim 4
Dependent Claim
53 words
The method of claim 1 further comprising the steps of adding a light setting resin of a different color than the light setting resin within the shell tooth form to an exterior of the shell tooth form and illuminating the added light setting resin to bond it to the shell tooth form exterior.
Claim 5
Dependent Claim
40 words
The method of claim 1 further comprising the step of disposing a second light setting resin within the transparent shell tooth form adjacent inside surfaces thereof, said second light setting resin having a different color from said light setting resin.
Claim 6
Dependent Claim
35 words
The method of claim 4 wherein said second light setting resin is disposed in said shell tooth form at a position enabling the crown to have a gum line color different from a body color.
Claim 7
Dependent Claim
30 words
The method of claim 4 wherein said second light setting resin is disposed in said shell tooth form at a position enabling the crown to have a shaded body color.
Claim 8
Dependent Claim
73 words
The method of claim 4 further comprising the steps of observing a color pattern of the light setting resins through the transparent shell tooth form while the shell tooth form is disposed over the prepared tooth, removing the filled shell tooth form to change the color pattern by addition and/or removal of the light setting resins and replacing the filled tooth form into the prepared tooth before setting of the light setting resins.
Claim 9
Independent Claim
78 words
A method of making a permanent replacement tooth comprising: setting a post in a patient's jaw; filling a transparent shell tooth form with a light setting resin; disposing the filled shell tooth form onto the post; illuminating the filled transparent shell tooth form to set the light setting resin therein and bond the light setting resin to the shell tooth form and post; and shaping and polishing the shell tooth form in situ to form a replacement tooth.
Claim 10
Independent Claim
78 words
A method of making a permanent replacement tooth comprising: setting a post in a patient's jaw; filling a transparent shell tooth form with a light setting resin; disposing the filled shell tooth form onto the post; illuminating the filled transparent shell tooth form to set the light setting resin therein and bond the light setting resin to the shell tooth form and post; and shaping and polishing the shell tooth form in situ to form a replacement tooth.
Claim 11
Dependent Claim
38 words
The method of claim 8 further comprising the steps of adding light setting resin to an exterior of the shell tooth form and illuminating the added light setting resin to bond it to the shell tooth form exterior.
Claim 12
Dependent Claim
53 words
The method of claim 8 further comprising the steps of adding a light setting resin of a different color than the light setting resin within the shell tooth form to an exterior of the shell tooth form and illuminating the added light setting resin to bond it to the shell tooth form exterior.
Claim 13
Dependent Claim
40 words
The method of claim 8 further comprising the step of disposing a second light setting resin within the transparent shell tooth form adjacent inside surfaces thereof, said second light setting resin having a different color from said light setting resin.
Claim 14
Dependent Claim
35 words
The method of claim 11 wherein said second light setting resin is disposed in said shell tooth form at a position enabling the crown to have a gum line color different from a body color.
Claim 15
Dependent Claim
30 words
The method of claim 11 wherein said second light setting resin is disposed in said shell tooth form at a position enabling the crown to have a shaded body color.
Claim 16
Dependent Claim
71 words
The method of claim 11 further comprising the steps of observing a color pattern of the light setting resins through the transparent shell tooth form while the shell tooth form is disposed over the post, removing the filled shell tooth form to change the color pattern by addition and/or removal of the light setting resins and replacing the filled tooth form into the post before setting of the light setting resins.
