Abstract
Embodiments include dental appliances, dental appliance systems, and methods of making and using such appliances. In one embodiment, a dental appliance includes a number of tooth apertures for the placement of teeth therein and a tab representing a position of a tooth that has not fully erupted and oriented to be received over the position of the tooth that has not fully erupted.
Claims12
A dental appliance for use with a tooth that is not fully erupted, comprising:
- a shell having a number of tooth apertures configured to receive and apply force to reposition teeth from one arrangement to a successive arrangement and include side surfaces that are configured to extend substantially to the patient's gumline, wherein the number of tooth apertures are configured to receive a number of teeth from only one of an upper or lower jaw of a patient, wherein the shell includes an outer surface opposite the number of tooth apertures that is shaped to match contours of the coronal surfaces of the teeth, and wherein the shell includes:
- a tab having a length to span across only a portion of a coronal surface of the tooth, in a distal direction, when fully erupted;
- wherein the tab includes a tooth contact surface shaped to mate with the portion of the coronal surface of the tooth and a surface opposite the tooth contact surface shaped to mate with an outer surface of a second appliance or a coronal surface of one or more teeth on an opposite jaw of the patient;
- wherein the tooth contact surface of the tab is positioned to receive the coronal surface of the tooth when the tooth is fully erupted;
- and
- wherein the tab includes side surfaces that are configured not to extend substantially to the patient's gumline when the tooth has fully erupted.

A dental appliance system for use with teeth that are not fully erupted, comprising:
- a first shell having cavity geometry apertures configured to receive and apply force to reposition teeth from one arrangement to a successive arrangement and include side surfaces that are configured to extend substantially to the patient's gumline, wherein the first shell is configured to fit over a first jaw of a patient, wherein the first shell includes an outer surface opposite the cavity geometry apertures that is shaped to match contours of the coronal surfaces of the teeth, and wherein the first shell includes:
- a first tab having a first length to span across only a portion of a coronal surface of a first tooth, in a distal direction, when fully erupted, wherein the first tab includes a tooth contact surface shaped to mate with the portion of the coronal surface of the first tooth and a surface opposite the tooth contact surface shaped to mate with an outer surface of a second shell or a coronal surface of one or more teeth on a second jaw of the patient, wherein the tooth contact surface of the first tab is positioned to receive the portion of the coronal surface of the first tooth when the tooth is fully erupted, and wherein the first tab includes side surfaces that are configured not to extend substantially to the patient's gumline when the tooth has fully erupted;
- and
- the second shell not connected to the first shell having cavity geometry apertures configured to receive and apply force to reposition teeth of the second jaw from one arrangement to a successive arrangement and include side surfaces that are configured to extend substantially to the patient's gumline, wherein the second shell is configured to fit over the second jaw of the patient, wherein the second shell includes the outer surface opposite the cavity geometry apertures that is shaped to match contours of the coronal surfaces of the teeth of the second jaw, and wherein the shell includes:
- a second tab having a second length to span across only a portion of a coronal surface of a second tooth, in a distal direction, when fully erupted, wherein the second tab includes a tooth contact surface shaped to mate with the portion of the coronal surface of the second tooth and a surface opposite the tooth contact surface shaped to mate with the surface opposite the tooth contact surface of the first shell or a coronal surface of one or more teeth on the first jaw of the patient, wherein the tooth contact surface of the second tab is positioned to receive the portion of the coronal surface of the second tooth when the tooth is fully erupted, and wherein the second tab includes side surfaces that are configured not to extend substantially to the patient's gumline when the tooth has fully erupted;
- and
- wherein the first and the second shells and the first and the second tabs are formed of a same material.
4 more elements
A method comprising:
- providing a first and a second dental appliance of a number of appliances, configured to be worn in succession by a patient, where the first and the second dental appliances include:
- a shell having a plurality of individual tooth apertures configured to receive and apply force to reposition teeth from one arrangement to a successive arrangement and include side surfaces that are configured to extend substantially to the patient's gumline, wherein the plurality of individual tooth apertures are configured to receive a number of teeth from only one of a corresponding upper or lower jaw of the patient, and wherein the shell includes an outer surface opposite the plurality of individual tooth apertures that is shaped to match contours of the coronal surface of the teeth;
- where the shell of the first dental appliance includes a tab of a first length that spans across only a portion of a coronal surface of a first tooth, in a distal direction, when fully erupted and includes side surfaces that are configured not to extend substantially to the patient's gumline when the first tooth has fully erupted;
- where the tab includes a tooth contact surface shaped to mate with the portion of the coronal surface of the first tooth and a surface opposite the tooth contact surface shaped to mate with the outer surface of the second appliance or a coronal surface of one or more teeth on an opposite jaw of the patient;
- where the tooth contact surface of the tab of the first length is positioned to receive the portion of the coronal surface of the first tooth when the tooth is fully erupted;
- and
- where the shell of the second dental appliance includes a tab of a second length greater than the first length having a tooth contact surface shaped to mate with a portion of a coronal surface of a second tooth that is fully erupted and where the tab of the second length is positioned to receive the portion of the coronal surface of the second tooth.
4 more elements
A dental appliance for use with a tooth that is not fully erupted, comprising:
- a shell configured to receive a number of teeth from only one of a corresponding upper or lower jaw of a patient, the shell including:
- a number of tooth cavity geometry apertures, each aperture shaped to mate with a corresponding tooth of the patient, and each aperture generally conforming to the corresponding tooth and having sides that are configured to extend substantially to the patient's gumline, wherein the shell includes an outer surface opposite the number of tooth cavity geometry apertures that is shaped to match contours of coronal surfaces of the number of teeth;
- and
- a tab having a length to span across only a portion of a coronal surface of the tooth, in a distal direction, when fully erupted and a tooth contact surface shaped to mate with the portion of the coronal surface of the tooth, wherein the tooth contact surface of the tab is positioned to receive the portion of the coronal surface of the tooth when the tooth is fully erupted, and a surface of the tab opposite the tooth contact surface shaped to mate with an outer surface of a second appliance or a coronal surface of one or more teeth on an opposite jaw of the patient a;
