  12. The indirect bonding tray (200) of claim 1, wherein the first impression (104) is distal of the second impression (106).
  13. The indirect bonding tray (200) of claim 1, wherein the first impression (104) is mesial of the second impression (106).
  14. The indirect bonding tray (200) of claim 1, wherein the orthodontic appliance is a molar tube.
  15. The indirect bonding tray (200) of claim 1, wherein the orthodontic appliance is an orthodontic bracket.
  16. The indirect bonding tray (200) of claim 1, wherein the orthodontic appliance is an auxiliary appliance.
  17. The indirect bonding tray (200) of claim 16, wherein the auxiliary appliance is a bite turbo, a button, or a hook.
  18. The indirect bonding tray (200) of claim 1, wherein the well (112) conforms to an outer surface of a molar tube buccal surface of the tooth.
  19. The indirect bonding tray (200) of claim 1, wherein the tooth is a first tooth, the second impression (106) is associated with a second tooth, and the occlusal base (204) defines a third impression conforming to at least a portion of an occlusal surface of a third tooth.
  20. The indirect bonding tray (200) of claim 19, wherein the third impression is adjacent to the first impression (104).

Description

FIELD The techniques described herein relate generally to dental appliances and, more particularly, to exemplary indirect bonding trays for orthodontic appliances. BACKGROUND Correct placement of orthodontic appliances for straight-wire orthodontic treatments can be important for orthodontic treatments, including to avoid undesirable tooth movements and/or extended treatment times. Such placement may be performed by direct or indirect bonding of appliances. Direct bonding can be carried out by placing the appliances directly on teeth, one tooth at a time, and not on a model, such as a plaster model. Indirect bonding of appliances can be carried out by placing the appliances on a model of a patient's teeth and transferring the model onto the patient's teeth for bonding of the appliances. Indirect bonding can achieve greater accuracy and/or effectiveness of straight-wire orthodontic treatments compared to direct placement of appliances by a clinical professional. US 2014/349241 A1 provides an orthodontic device-setting tool with: a fitting section having a fitting surface, which covers and fits together with at least one of the incisal margin, the dental cusp, or the occlusal surface of a tooth; a foundation section, which has a back surface that adheres closely to the labial/buccal surface or the lingual surface of the tooth and has, on the surface opposite the back surface, a front face on which the orthodontic device is mounted; and a connecting section that connects the fitting section and the foundation section. The tool has a frame section, which protrudes from the front face of the foundation section and can fit together with the orthodontic device. Use of the orthodontic device-setting tool makes it possible to mount orthodontic devices such as corrective brackets without holding the patient for long periods of time and to mount the orthodontic devices accurately at the desired three-dimensional mounting positions for the orthodontic devices regardless of the skill level of the dentist practitioner. Moreover, the tool can even be used with mass-produced general purpose orthodontic devices, which are not orthodontic devices that have been specially customized as to design, cut, etc. for individual patients. CN 111991108 A discloses an indirectly-pasted bracket transfer guide plate and an installation and separation method thereof. The bracket transfer guide plate comprises occlusion parts used for being matched with tooth occlusal surfaces and bracket clamps used for fixing brackets, and the bracket clamps comprise lip-direction pressing pieces and retention assemblies, wherein the lip-direction pressing pieces are connected with the occlusion parts and apply acting force through self-deformation to enable the brackets to be attached to the tooth lip side faces, the retention assemblies comprises a plurality of retention arms oppositely arranged in the tooth arrangement direction, and positioning parts acting with the brackets are arranged at the ends, away from the occlusion parts, of all the retention arms correspondingly; release grooves are formed between all the retention arms and the lip-direction pressing pieces correspondingly; and a clamping space for constraining the brackets is formed by all the retention arms, all the positioning parts, all the lip-direction pressing pieces and the tooth lip side faces in an enclosed mode. According to the technical scheme, through arrangement of the lip-direction pressing pieces and the retention assemblies, the advantages of high positioning precision in the bracket mounting process and easy separation in the bracket transfer guide plate dismounting process are both considered, meanwhile, the structure is simple and stable, and high popularization value is achieved. CN 211355976 U discloses a positioning unit, a positioner and a positioning method of an orthodontic bracket, the positioning unit of the orthodontic bracket comprises a bracket positioning block and an occlusion positioning block which are detachably connected with each other; the occlusal positioning block is used for coupling occlusal surfaces of teeth; wherein the bracket positioning blockis used for coupling an orthodontic bracket and releasing the orthodontic bracket to teeth, the bracket positioning block is provided with an arch wire channel in the mesio-distal direction, and the arch wire channel is used for allowing an arch wire arranged in an arch wire groove of the orthodontic bracket to pass through. According to the positioning unit and the positioner, the arch wire groove is prevented from being occupied, the arch wire channel and the orthodontic bracket capable of being coupled with and carrying the arch wire are arranged, the arch wire is carried during indirect bonding, the operation time and operation steps are reduced, the pain of a patient is relieved, the workload of a doctor is reduced, and the development of an orthodontic technology is greatly promoted.
