Ultrasonic devices, systems, and methods for orthodontic treatment performed with aligners are described. Such devices, systems, and methods 5 are to provide multiplicative treatment-duration shortening for patients under orthodontic treatment with aligners, such as clear aligners. Communication of desired ultrasound treatment can be communicated from an aligner to an ultrasound device by a communication means or a communication module using an identification number on the aligner and means of entering the 10 identification number into the system, an identification number on an external document and means of entering the identification number into the system, a scannable code and code reader, and an assessment by a dentist and means of entering the assessment into the system, a radio-frequency identification (RFID) transponder and RFID reader, a change in material properties of the 15 aligner and means of reading the material properties, or a change in optical properties and means of reading the optical properties.

A method for producing an orthodontic or dental appliance includes laminating a layer of polyethylene terephthalate (PET) with a layer of polyethylene to form a multilayer film, forming the multilayer film into the shape of an orthodontic appliance, trimming the formed film to a desired shape, and removing the layer of polyethylene. In one embodiment, the appliance is a multi-layer structure formed from two adjacent layers of PET with a plurality of functional elements such as sensors or actuators between the two layers.

An orthodontic remodeling system includes an extraoral vibratory source coupled to a bite plate, where the extraoral vibratory source is operable to vibrate the bite plate at a frequency in a range of 0.1 to 400 Hz. The bite plate is configured to deliver cyclic forces simultaneously to teeth of the maxillary and mandibular arches, and the bite plate and the extraoral vibratory source are held during use only by clamping with the teeth. A battery is operable to power the extraoral vibratory source, and a processor is configured to control the extraoral vibratory source. Electronic media is operable to capture data indicating usage duration and usage frequency to allow patient compliance to be determined.

A device and method for delivering vibration to a dentition of the user is provided. The device includes a mouthpiece body configured to be placed intraorally and a plurality of pads coupled to a perimeter of the mouthpiece body. The mouthpiece body comprises a convex curvature that approximately corresponds to a curvature of the user's palate. The mouthpiece body further comprises at least one open portion configured to permit passage of any liquid that accumulates around the mouthpiece body during use. During use, the plurality of pads is configured to be placed in vibrational contact with the dentition of the user.

Embodiments of the present disclosure are directed to devices and methods for reducing loose dentition during clear aligner treatment with vibration. According to various implementations, a vibrational dental device configured to vibrate at a frequency between about 20 Hz to about 250 Hz may be obtained. Subjects undergoing clear aligner treatment may be treated for about five minutes daily with the exemplary vibrational dental device. The extend of loose dentition can be reduced by the vibration treatment, while maintaining desired movement of the teeth during orthodontic treatment.

Embodiments of the present disclosure are directed to devices and methods for reducing root resorption during clear aligner treatment with vibration. According to various implementations, a vibrational dental device configured to vibrate at a frequency of about 120. Hz may be obtained. Subjects undergoing clear aligner treatment may be treated for about five minutes daily with the exemplary vibrational dental device. The extend of root resorption of the four incisors may be reduced by the vibration, while maintaining desired movement of the teeth during orthodontic treatment.

Embodiments of the present disclosure are directed to apparatuses and methods for pre-conditioning an extraction site for dental implantation. In one implementation, a method for pre-conditioning an extraction site for dental implantation includes providing a vibrational dental device configured to vibrate at a frequency higher than about 20 Hz. The method further includes providing instructions for mechanically vibrating, using the vibrational dental device, a tooth at the extraction site for about a predetermined period of time daily over a treatment period before extracting the tooth. The mechanical vibration may prepare the extraction site to be in a healthier condition for receiving an implant.

Orthodontic system anchoring method and custom apparatus affixed to teeth, TADs and/or tooth positioning and stabilization appliances and/or orthodontic auxiliaries. Each appliance has mechanical fasteners structured to secure segments of a curable flexible resin rope called a flex fit module (FFM). The FFM is moldable and adaptable to the oral cavity between mechanical fasteners in an uncured first mode where it is cut to length, positioned around the anatomy of the mouth and attached to clamps or fasteners at each end. Each fastener has a clamp attached to orthodontic auxiliaries, orthodontic appliances or onto a TAD for anchorage purposes. One end of this custom appliance is usually attached via a clamp manufactured as part of a bracket or band to a tooth. The other end is connected to an appliance, tad or auxiliary. Once connected together the system is cured and becomes a solid entity ready to accept orthodontic forces.

A device for orthodontic treatment is disclosed. The device includes a first actuator configured to be attached to an orthodontic appliance and located proximate to a dentition. A second actuator is configured to be attached to the orthodontic appliance and located proximate to the dentition. A signal generator is in electrical communication with the first actuator and the second actuator. The signal generator is configured to provide a first drive signal to the first actuator and a second drive signal to the second actuator. In this way each actuator causes vibrational forces to be induced in the dentition. The actuators are configured such that the induced vibrational forces interfere with one another to cause an increased amplitude at a predetermined location in the dentition.

A device for accelerating tooth movement under orthodontic treatment is disclosed. The device includes a vibrational source and a patient-specific tray. The device applies vibrational forces with prescribed frequency and intensity to the teeth under orthodontic treatment with traditional appliances, such as bracket-wire system or aligner. The patient-specific tray ensures the vibrational stimulations on the teeth to be moved. The level of stimulation intensity can be controlled by varying the preload on each of the teeth based on the clinician's prescription. The tray can be further modified to ensure continuous delivery of the desired vibrational forces on the teeth when they move during the treatment.
