Abstract
In some examples, a tool for forming a dental restoration comprises a preformed mold body configured to provide a patient-specific, customized fit with at least one tooth to be restored of a patient. The mold body is configured to align with a portion of a surface of the at least one tooth, and is 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 at least one tooth to be restored of the patient. The portion of desired tooth structure defines a transition from a supragingival surface of the at least one tooth to a subgingival surface of the at least one tooth.
Claims24
A tool for forming a dental restoration, the tool comprising:
- a preformed mold body configured to provide a patient-specific, customized fit with at least one tooth to be restored of a patient, the mold body configured to align with a portion of a surface of the at least one tooth,
- 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 at least one tooth to be restored of the patient,
- wherein the mold body comprises a first registration arm projecting in a generally mesial-distal direction from a first side of the mold body, wherein the first registration arm is configured to align with at least a portion of an occlusal or an incisal surface of a first tooth adjacent to the at least one tooth to be restored and a second registration arm projecting in a generally mesial-distal direction from a second side of the mold body, wherein the second registration arm is configured to align with at least a portion of an occlusal or an incisal surface of a second tooth also adjacent to the at least one tooth to be restored.
