Abstract: A custom tool for forming a dental restoration in a mouth of a patient includes a one-piece mold body providing for a customized fit with at least one tooth of the patient, the one-piece mold body including an occlusal portion forming an occlusal surface corresponding with an occlusal surface of the tooth, a mesial proximal portion forming a mesial proximal surface corresponding with a mesial proximal surface of the tooth, and a distal proximal portion forming a distal proximal surface corresponding with a distal proximal surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth. The occlusal portion, the mesial proximal portion, and the distal proximal portion are based on three-dimensional scan data of the mouth of the patient.

Abstract: A custom tool for forming a dental restoration in a mouth of a patient includes a facial mold body for a patient-specific, customized fit with the facial side of at least one tooth of the patient, wherein the facial mold body includes a restorative portion and a first engagement portion extending away from the restorative portion; a lingual mold body for a patient-specific, customized fit with the lingual side of the tooth of the patient, wherein the lingual mold body includes a restorative portion and a first engagement portion extending away from the restorative portion; wherein the first engagement portion of the facial mold body interlocks with the first engagement portion of the lingual mold body; and wherein the facial mold body and lingual mold body are configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of at least one tooth to be restored.

Abstract: A custom tool for forming a dental restoration in a mouth of a patient includes a mold body providing for a customized fit with at least one tooth of the patient. The mold body includes a facial portion forming a facial surface corresponding with a facial surface of the tooth, and a separate lingual portion forming a lingual surface corresponding with a lingual surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth.

Abstract: A method of making an adhesive is provided, including obtaining an actinic radiation-polymerizable adhesive precursor composition disposed against a surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. The first portion and the second portion are adjacent to or overlapping with each other and the first irradiation dosage and the second irradiation dosage are not the same. The method forms an integral adhesive having a variable thickness in an axis normal to the surface of the actinic radiation-transparent substrate. Also, an adhesive article is provided, including a substrate having a major surface and an integral adhesive disposed on the major surface of the substrate.
