Method of administering adhesive to bond orthodontic brackets
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.
1. 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.
2. The method of claim 1 , further comprising transferring the dispensed adhesive to the bonding surface of the orthodontic bracket.
3. The method of claim 2 , further comprising distributing the dispensed adhesive over the bonding surface of the orthodontic bracket.
4. The method of claim 2 , further comprising loading a well of an indirect bonding (IDB) tray with the orthodontic bracket.
5. The method of claim 4 , further comprising storing the loaded IDB tray in a light-proof case to prevent the adhesive from curing.
6. The method of claim 4 , further comprising placing the loaded IDB tray on the physical tooth to position the orthodontic bracket at the digitally planned placement.
7. The method of claim 6 , further comprising exposing the adhesive to UV light to cure the adhesive.
8. The method of claim 1 , wherein the container is a syringe.
9. The method of claim 1 , further comprising cutting the dispensed adhesive from an end of the container.
10. 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.
11. The kit of claim 10 , wherein the adhesive quantity graphic is one of a plurality of adhesive quantity graphics, and the instructional guide further comprising a plurality of tooth identifiers corresponding to respective teeth of the patient, each of the plurality of adhesive quantity graphics being respectively juxtaposed one of the plurality of tooth identifiers to visually indicate a quantity of dispensed adhesive to be applied to the orthodontic bracket corresponding to the tooth identifier.
