Abstract

A custom tool for forming a dental restoration in a mouth of a patient includes a first mold body providing for a customized fit with at least one tooth of the patient. The first mold body includes a portion corresponding with at least a first surface of the tooth and an interproximal portion corresponding with an interproximal surface of the tooth, the interproximal portion being of unitary construction. The first mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing a first portion of missing tooth structure of the tooth.

First claim

What is claimed is:

1. A custom tool for forming a dental restoration in a mouth of a patient, the custom tool comprising:
a first mold body providing for a customized fit with at least two teeth of the patient, wherein the first mold body includes a portion corresponding with at least a first surface of a tooth of the at least two teeth and an interproximal portion corresponding with an interproximal surface of a tooth of the at least two teeth,
wherein the first mold body is configured to combine with a tooth of the at least two teeth of the patient to form a mold cavity encompassing a portion of missing tooth structure of at least a tooth of the at least two teeth, and
the custom tool further including a port and a plug, wherein the plug includes a tip surface corresponding to a surface of the tooth, and wherein a dental restoration material may be injected into the mold cavity through the port.

2. The custom tool of claim 1 , wherein the interproximal portion extends entirely through an interproximal space between the tooth receiving the restoration and an adjacent tooth.

3. The custom tool of claim 1 , further comprising:
a second mold body providing for a customized fit with the at least one tooth of the patient, wherein the second mold body includes a portion corresponding with a second surface of the tooth,
wherein the second mold body is configured to combine with the first mold body and the tooth of the patient to form the mold cavity encompassing the portion of missing tooth structure of the tooth.

4. The custom tool of claim 1 , wherein the mold cavity forms an inner surface corresponding to the tooth's outer surface prior to restoration.

5. The custom tool of claim 1 , wherein a portion of the second mold body overlaps with a portion of the first mold body, and wherein the first and second mold body each encompass a first portion of the missing tooth structure.

6. The custom tool of claim 1 , further comprising:
dental restoration material in the mold cavity to form a first partial dental restoration; and
additional dental restoration material in the mold cavity to form a second partial dental restoration,
wherein a mold line between the first partial dental restoration and second partial dental restoration is located outside the interproximal space between the at least one tooth receiving the restoration and an adjacent tooth.

7. The custom tool of claim 1 , wherein the dental restoration provides a dental veneer restoration on the at least one tooth.

8. The custom tool of claim 1 , wherein the molds are formed based on three-dimensional scan data of the mouth of the patient.
