Adjusting a tooth position
The present disclosure provides methods, devices, and systems for adjusting a tooth position. A system for adjusting a tooth position can include an attachment configured to be attached to a tooth to be moved, a dental appliance including a guide slot configured to receive the attachment and to define an adjustment trajectory of the tooth, and an adjustment band to generate force on the tooth to move the tooth along the adjustment trajectory.
1. A dental appliance system, comprising:
a dental appliance having:
a shell body configured to receive plurality of a patient's teeth, said shell body including a guide slot formed therein, the guide slot configured to guide an attachment attached to a tooth along a target path for movement of the tooth; and
a hook located on a same side of the dental appliance as the guide slot and the hook is spaced apart from the guide slot;
an adjustment band configured to generate force on the tooth for movement of the tooth to a target position along the target path;
wherein a first end of the adjustment band is configured to be attached to the attachment; and
a second end of the adjustment band is configured to be attached to the hook provided on the dental appliance.
2. The system of claim 1 , wherein the guide slot includes at least one side portion that interacts with the attachment to define a movement trajectory of the tooth.
3. The system of claim 1 , wherein the guide slot includes at least one side portion that interacts with the attachment to control tipping of the tooth.
4. The system of claim 1 , wherein the guide slot is on a lingual side of a patient's dentition, and wherein the appliance includes a different guide slot on a buccal side of the patient's dentition.
5. The system of claim 1 , wherein the guide slot has an end portion that is configured to stop movement of the attachment when it reaches the target position.
6. The system of claim 1 , wherein an edge of the guide slot comprises a thicker material as compared to at least one other portion of the dental appliance.
7. The system of claim 1 , wherein the guide slot has a parallel orientation with respect to a jaw of a patient upon which the appliance is to be placed.
8. A system, comprising:
an attachment configured to be attached to a tooth to be moved;
a dental appliance having a shell body configured to receive plurality of a patient's teeth, said shell body including:
a guide slot configured to receive the attachment and to define an adjustment trajectory of the tooth;
a hook located on a same side of the dental appliance as the guide slot and the hook is spaced apart from the guide slot; and
an adjustment band to generate force on the tooth to move the tooth along the adjustment trajectory.
9. The system of claim 8 , wherein the guide slot is on a lingual side of the patient's dentition.
10. The system of claim 8 , wherein the guide slot is on a buccal side of the patient's dentition.
11. The system of claim 8 , wherein the attachment is configured to receive a first end of the adjustment band.
12. The system of claim 11 , further comprising the hook attached to the dental appliance configured to receive a second end of the adjustment band.
13. The system of claim 8 , wherein the attachment includes one or more chamfered edges.
14. The system of claim 8 , wherein the attachment extends through the guide slot.
15. The system of claim 8 , further comprising a dimple on at least one of the tooth and the dental appliance configured to reduce rotational force on the tooth.
16. The system of claim 8 , further comprising a bulge in the appliance configured to reduce rotational force on the tooth.
