## Abstract

An orthodontic system and method for aligning at least one tooth of an upper jaw or a lower jaw of a patient. In the system and method at least one orthodontic appliance can be provided which may include at least one force exerting member for applying a force to move the at least one tooth, a tooth movement sensor for obtaining tooth movement data, and a tooth movement monitor for calculating at least one of the distance the at least one tooth has moved and a current position of the at least one tooth from the tooth movement data. An electronic control console may be operatively connected to the force exerting member and in data communication with the tooth movement monitor, for controlling the operation of the force exerting member using the at least one of the distance the at least one tooth has moved and the current position of the at least one tooth.

## Claims

### Claim 1

An electronic control console for controlling the operation of at least one orthodontic appliance which moves and aligns at least one tooth of at least one jaw of a patient, the electronic control console comprising:
a fluid pump which causes a force exerting member of the at least one orthodontic appliance to apply a force on the at least one tooth, the force exerting member comprising at least one inflatable element that is inflatable with a fluid which causes the at least one inflatable element to apply and maintain the force applied to the at least one tooth;
a fluid sensor arrangement, a solenoid valve, a controller, and a communication interface, the fluid sensor arrangement including a fluid pressure sensor, a fluid flow sensor, and fluid volume sensor, the fluid pressure sensor detects a fluid pressure of the fluid pump, the fluid flow sensor measures a fluid flow rate of the fluid pump, and the fluid volume sensor measures a fluid volume of the fluid pump;
wherein the communication interface interfaces with a tooth movement monitor to receive tooth movement data obtained from a force sensor attached to or partially embedded in the interior surface of a facial, lingual, or base wall, or a combination thereof of the mouthpiece, such that the force sensor is adapted to contact a side of the at least one tooth, which is opposite a side of the tooth adapted to be in contact with the force exerting member;
wherein the fluid pressure, flow, and volume measurements are used by the controller in conjunction with the tooth movement data to control the operation of the force exerting member.

### Claim 2 (depends on 1)

The electronic control console of claim 1, wherein the controller of the electronic control console is programmable.

### Claim 3 (depends on 1)

The electronic control console of claim 1, wherein the communication interface allows data communication with a communication device operated by the patient, thereby allowing at least one of a distance the at least one tooth has moved and a current position of the at least one tooth, whether in real time or stored, to be communicated by the communication device of the patient to a remotely located communication device of a remotely located dentist or other user.

### Claim 4 (depends on 3)

The electronic control console of claim 3, wherein the communication interface allows receipt of program instructions from the remotely located communication device operated by the dentist or other user, via the communication device operated by the patient, the program instructions programming the controller of the control console.

### Claim 5 (depends on 1)

The electronic control console of claim 1, wherein the communication interface allows receipt of program instructions from a remotely located communication device operated by a dentist or other user, the program instructions programming the controller of the control console.

### Claim 6 (depends on 1)

The electronic control console of claim 1, wherein the communication interface allows a dentist or other user to remotely access the control console and the at least one orthodontic appliance, via a communication device operated by the dentist and a communication device operated by a patient, to initiate a real time measurement of at least one of a distance the at least one tooth has moved and a current position of the at least one tooth, or obtain the at least one of the distance the at least one tooth has moved and the current position of the at least one tooth stored in the controller of the control console.
