Abstract

A tool for forming a dental restoration includes a mold body configured to provide a customized fit with at least one tooth of a patient. In some examples, the mold body defines an aperture configured to align with a portion of a surface of a tooth. The aperture is sufficiently large to allow placement and flow of restorative material over the desired portion of the surface of the tooth to be restored. The mold body is configured to combine with the at least one tooth of the patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth to be restored.

First claim

What is claimed is:

1. A tool for forming a dental restoration, the tool comprising:
a mold body including one or more mold body parts configured to provide a customized fit with at least one tooth of a patient, a single body part of the one or more the mold body parts defining a seamless aperture configured to align with a portion of a surface of a tooth to be restored of the at least one tooth and provide a through-hole from an exterior surface of mold body part to an interior surface thereof, the mold body being configured to combine with the at least one tooth to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth to be restored, wherein the aperture is larger than a tip of a restorative dental material introduction device and configured to allow placement and flow of a restorative material into the mold cavity to cover the portion of the surface of the tooth to be restored,
at least one door corresponding to the portion of the surface of the tooth to be restored, at least a portion of the door being configured to mate with the aperture,
wherein the mold body and the door are configured to combine with the at least one tooth to define the mold cavity.

2. The tool of claim 1 , wherein a ratio of an area of the aperture to a cross-sectional area of the tip is greater than or equal to about 2:1.

3. The tool of claim 1 , wherein the aperture is configured to align with a majority of the portion of the surface of the tooth to be restored.

4. The tool of claim 1 , wherein the one or more mold body parts comprises a first mold body part, a second mold body part, wherein the second mold body part is separable from and engageable with the first mold body part, and wherein the first and second mold body parts are configured to combine with the at least one tooth of the patient to define the mold cavity.

5. The tool of claim 4 , wherein, when the first and second mold body parts combine with the at least one tooth of the patient to define the mold cavity, at least a portion of the first mold body part is configured to abut a portion of the second mold body part, wherein at least one of the portion of the first mold body part or the portion of the second mold body part comprises an overbuilt portion such that, when the portion of the first mold body part abuts the portion of the second mold body part, the overbuilt portion is configured to provide intimate contact between the portion of the first mold body part and the portion of the second mold body part.

6. The tool of claim 1 , wherein the aperture has a perimeter defined by a single body part of the one or more mold body parts.

7. The tool of claim 1 , wherein the door is attached to the mold body via a hinge.

8. The tool of claim 1 , wherein a side of the door configured to mate with the mold body defines a chamfered edge.

9. The tool of claim 1 , wherein the at least one door comprises a first door configured for one or more of final shaping or final layering of at least a portion of the dental restoration, the tool further comprising one or more of:
a second door, at least a portion of the second door being configured to mate with the aperture, the second door being configured for shaping an underlying shade layer of at least the portion of the dental restoration;
a third door, at least a portion of the third door being configured to mate with the aperture, the third door being configured to form one or more of:
one or more mamelons,
one or more grooves, or
one or more pits;

a fourth door, at least a portion of the fourth door being configured to mate with the aperture, the fourth door being configured for near net shaping of at least the portion of the dental restoration; or
a fifth door, at least a portion of the fifth door being configured to mate with the aperture, the fifth door being configured for applying an intermediate layer of restorative material, the intermediate layer of restorative material comprising a first restorative material that is different than a material applied during final layering by the first door.

10. A method of forming a dental restoration, the method comprising:
attaching a mold body to at least one tooth of a patient, the mold body including one or more mold body parts configured to provide a customized fit with at least one tooth of a patient, a single body part of the one or more the mold body parts defining a seamless aperture configured to align with a portion of a surface of a tooth to be restored of the at least one tooth and provide a through-hole from an exterior surface of mold body part to an interior surface thereof, the mold body being configured to combine with the at least one tooth to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth to be restored, wherein the aperture is larger than a tip of a restorative dental material introduction device and configured to allow placement and flow of a restorative material into the mold cavity to cover the portion of the surface of the tooth to be restored,
filling the mold cavity with restorative material by at least one of: placing the restorative material through the aperture and into the mold cavity, prefilling the mold cavity with the restorative material before attaching the mold body to the at least one tooth, or placing the restorative material on the tooth to be restored before attaching the mold body to the at least one tooth;
after filling the mold cavity with restorative material, placing at least a portion of a door body within the aperture, the door body corresponding to the portion of the surface of the at least one tooth to be restored, at least the portion of the door body being configured to mate with the aperture,
curing the restorative material; and
removing the mold body from the at least one tooth.

11. The method of claim 10 , wherein filling the mold cavity with restorative material comprises aligning a tip of a restorative dental material introduction device with the aperture and introducing the restorative material into the mold cavity via the restorative dental material introduction device, wherein a ratio of an area of the aperture to a cross-sectional area of the tip is greater than or equal to about 2:1.

12. The method of claim 10 , wherein the one or more mold body parts comprises a first mold body part and a second mold body part, the method further comprising:
attaching a second mold body part to the at least one tooth, the second mold body part being configured to provide a customized fit with the at least one tooth, the first and second mold body parts being configured to combine with the at least one tooth of the patient to form the mold cavity encompassing at least the portion of desired dental structure of the tooth to be restored.

13. The method of claim 12 , wherein when the first and second mold body part combine with the at least one tooth of the patient to form the mold cavity, at least a portion of the first mold body part abuts a portion of the second mold body part, wherein at least one of the portion of the first mold body part or the portion of the second mold body part comprises an overbuilt portion such that, when the portion of the first mold body part abuts the portion of the second mold body part, the overbuilt portion provides intimate contact between the portion of the first mold body part and the portion of the second mold body part.

14. The method of claim 12 , wherein the first and second mold body parts are configured to form a door hinge when the first and second mold body parts are engaged together, wherein, when the first and second mold body parts combine
