Abstract
The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment formation structures. One dental appliance includes a body having a first surface shaped to abut an exterior surface of a tooth and a well portion of the first surface shaped to form an attachment that is to be attached to the exterior surface of the tooth, a release layer formed over a surface of the well to allow the attachment to be removed from the well, and an attachment material that is used to form the attachment positioned within the well.
Claims20
An attachment formation structure system, comprising:
- a body including a conformal surface shaped and configured to conform to contours of a buccal exterior surface of a tooth model, the body including a well portion having a shape and orientation for forming an orthodontic attachment at a specified location on the buccal exterior surface of the tooth model;
- an attachment material within the well portion that is configured to form the orthodontic attachment on the tooth model;
- a release layer positioned between an interior surface of the well portion and the attachment material, the release layer configured to allow the orthodontic attachment to be removed from the well portion;
- and
- a release liner covering an opening of the well portion to encapsulate the attachment material between the release liner and the release layer within the well portion.
An attachment formation structure system utilized in conjunction with a dental appliance to apply forces to reposition one or more teeth, the attachment formation structure system comprising:
- a body including a conformal surface shaped to conform to contours of an exterior surface of a tooth model, the body including a well portion having an attachment material therein that is configured to form an orthodontic attachment, wherein the well portion has a shape and orientation for positioning the orthodontic attachment at a specified location on the exterior surface of the tooth model,
- wherein a release layer is positioned between an interior surface of the well portion and the attachment material, the release layer configured to allow the orthodontic attachment to be removed from the well portion,
- wherein an outer surface of the attachment material includes a layer of adhesive material that is configured to bond the orthodontic attachment to the exterior surface of the tooth model;
- and
- a release liner covering an opening of the well portion to encapsulate the layer of adhesive material and the attachment material between the release liner and the release layer within the well portion.
An attachment formation apparatus utilized in conjunction with a dental positioning appliance to apply forces to reposition one or more teeth, the attachment formation apparatus comprising:
- a body including a conformal surface shaped and configured to conform to contours of a buccal exterior surface of a tooth model, the body including a well portion having a shape and an orientation for positioning an orthodontic attachment at a specified location on the buccal exterior surface of the tooth model;
- an attachment material within the well portion that is configured to form the orthodontic attachment on the tooth model;
- a release layer positioned between an interior surface of the well portion and the attachment material, the release layer configured to allow the orthodontic attachment to be removed from the well portion;
- and
- a release liner covering an opening of the well portion to encapsulate the attachment material between the release liner and the release layer within the well portion, wherein the release liner conforms to a shape of the buccal exterior surface of the tooth model.
An attachment formation structure system utilized in conjunction with a dental positioning appliance to apply forces to reposition one or more teeth, the attachment formation structure system comprising:
- a body including:
- a conformal surface shaped and configured to be positioned against and conform to contours of a buccal exterior surface of a tooth model;
- a well portion having an attachment material therein that is configured to form an orthodontic attachment, the well portion having a shape and an orientation for positioning the orthodontic attachment at a specified location on the buccal exterior surface of the tooth model;
- a release layer positioned between an interior surface of the well portion and the attachment material, the release layer configured to allow the orthodontic attachment to be removed from the well portion;
- and
- a release liner covering an opening of the well portion to encapsulate the attachment material between the release liner and the release layer within the well portion;
- wherein the body includes a first segment coupled to a second segment at a score line therebetween, wherein the score line is configured to allow removal of the first segment from the one or more teeth while the second segment remains on the one or more teeth.
