System for producing a one-piece orthodontic jig and attachments
A method for producing a one-piece orthodontic jig and attachments employs a computer-aided design (CAD) system to create a model of a patient's dental anatomy. A set of orthodontic attachments and their desired positions are also designed in the CAD model. An orthodontic jig for temporarily positioning the attachments during the bonding process is then designed that includes features for registering the jig to selected teeth, together with connecting members that detachably connect the attachments to the jig and hold the attachments in their desired position on the patient's teeth during the bonding process. The orthodontic jig and attachments is fabricated as a single piece by computer-controlled manufacturing (e.g., 3D printing) based on the CAD model.
1. A method for producing a one-piece orthodontic jig and attachments comprising:
creating a model of a patient's dental anatomy in a computer-aided design (CAD) system;
designing in the CAD model a set of orthodontic attachments for treatment of the patient, including the desired positions of the attachments on selected teeth in the CAD model;
designing in the CAD model an orthodontic jig as a single piece with the attachments for temporarily positioning the attachments during a bonding process to selected teeth, said jig including features for registering the jig to selected teeth, and further including connecting members having thin, elongated members connecting the attachments to the jig designed to hold the attachments in their desired position on the patient's teeth during the bonding process; and
producing an orthodontic jig and attachments as a single piece by computer-controlled manufacturing based on the CAD model.
2. The method of claim 1 wherein the orthodontic jig and attachments are produced by three-dimensional printing.
3. The method of claim 1 wherein the orthodontic jig and attachments are produced by computer numerical control (CNC) machining.
4. The method of claim 1 wherein the orthodontic jig and attachments are produced by computer numerical control (CNC) milling.
5. The method of claim 1 wherein the orthodontic jig includes features to register the orthodontic jig to the occlusal surfaces of selected teeth.
6. A method of orthodontic treatment comprising:
creating a model of a patient's dental anatomy in a computer-aided design (CAD) system;
designing in the CAD model a set of orthodontic attachments for treatment of the patient, including the desired positions of the attachments on selected teeth in the CAD model;
designing in the CAD model an orthodontic jig as a single piece with the attachments for temporarily positioning the attachments during a bonding process to selected teeth, said jig including features for registering the jig to selected teeth, and further including connecting members having thin, elongated members connecting the attachments to the jig designed to hold the attachments in their desired position on the patient's teeth during the bonding process;
producing an orthodontic jig and attachments as a single piece by computer-controlled manufacturing based on the CAD model;
placing the orthodontic jig and attachments on the patient's teeth using the registering features;
bonding the attachments to the patient's teeth with the jig and connecting members providing accurate positioning of the attachments with respect to the patient's teeth; and
cutting the thin, elongated members to detach the attachments and removing the jig from the patient's teeth.
7. The method of claim 6 wherein the orthodontic jig and attachments are produced by three-dimensional printing.
8. The method of claim 6 wherein the orthodontic jig and attachments are produced by computer numerical control (CNC) machining.
9. The method of claim 6 wherein the orthodontic jig and attachments are produced by computer numerical control (CNC) milling.
10. The method of claim 6 wherein the orthodontic jig includes features to register the orthodontic jig to the occlusal surfaces of selected teeth.
11. A one-piece orthodontic jig and attachments made by a process comprising the steps of:
creating a model of a patient's dental anatomy in a computer-aided design (CAD) system;
designing in the CAD model a set of orthodontic attachments for treatment of the patient, including the desired positions of the attachments on selected teeth in the CAD model;
designing in the CAD model an orthodontic jig as a single piece with the attachments for temporarily positioning the attachments during a bonding process to selected teeth, said jig including features for registering the jig to selected teeth, and further including connecting members having thin, elongated members connecting the attachments to the jig designed to hold the attachments in their desired position on the patient's teeth during the bonding process; and
producing an orthodontic jig and attachments as a single piece by computer-controlled manufacturing based on the CAD model.
