Abstract
Methods of administering a quantity of adhesive to bond orthodontic brackets is disclosed herein. The quantity of adhesive to bond a selected bracket to a tooth at a specific location thereon can be calculated based on a known geometry of the selected bracket and a digital model of the patient's teeth. A instruction guide can visually indicate with a graphic the amount of adhesive to dispense from a syringe or other device to bond the selected bracket to the surface of the tooth at a specific location planned in the digital model.
Claims11
A method comprising:
- determining, by way of a digital model, a custom quantity of adhesive to bond an orthodontic bracket to a physical tooth at least based on a geometry of a bonding surface of the orthodontic bracket and a geometry of a surface of a digital tooth in the digital model representative of the physical tooth at a location corresponding to a digitally planned placement of the orthodontic bracket;
- dispensing an adhesive from an opening of a container onto an adhesive quantity graphic on an instructional guide;
- visually comparing a length of a profile of the dispensed adhesive with a length of the adhesive quantity graphic on the instructional guide, wherein the length of the adhesive quantity graphic is based on the determined custom quantity of adhesive, and wherein a width of the opening of the container and a width of the adhesive quantity graphic are the same;
- and discontinuing the dispensing of the adhesive from the container when the length of the profile of the dispensed adhesive matches the length of the adhesive quantity graphic on the instructional guide.
1 more element
A kit comprising:
- a container comprising an opening providing access into a cavity configured to hold an adhesive therein;
- and
- an instructional guide comprising an adhesive quantity graphic, wherein a length of the adhesive quantity graphic is configured to be visually compared with a length of a profile of adhesive dispensed from the container through the opening onto the adhesive quantity graphic to determine a quantity of dispensed adhesive to be applied to an orthodontic bracket for bonding on a location of a physical tooth of a patient, wherein a width of the opening of the container and a width of the adhesive quantity graphic are the same, and wherein the length of the adhesive quantity graphic corresponds to a custom quantity of adhesive determined, by way of a digital model, to bond the orthodontic bracket to the physical tooth at least based on a geometry of a bonding surface of the orthodontic bracket and a geometry of a surface of a digital tooth in the digital model representative of the physical tooth at a location corresponding to a digitally planned placement of the orthodontic bracket.
