A vibration device for dental use is provided, including a support member and a vibration transmission member. The support member is adapted to fit in the space between the upper and lower teeth on one side of the mouth, and includes a frame and an elastic layer. The frame is configured to maintain a shape defining an inner cavity having a first opening formed on the first side of the support member and a second opening formed on the second side of the support member. The elastic layer covers the surfaces of the frame. The vibration transmission member has a connector end for coupling to a vibration source and an insertion end configured to be inserted into the inner cavity of the support member so as to transmit the vibration energy generated by the vibration source to the upper and lower teeth of the patient.

Provided is a mouthpiece which is mounted in an oral cavity for use in changing the shape of the skull including the maxillary bone and is composed of a plurality of segment pieces, at least some of the segment pieces being configured to approach or be spaced apart from each other by means of a screw, wherein the surfaces of the segment pieces facing or contacting the skin in the oral cavity are configured such that the segment pieces overlap with each other, such that a gap does not occur in spite of the approaching or spacing-apart movement of the segment pieces relative to each other.

A system for generating occlusal loading is provided, including a loading appliance and a controller. The loading appliance includes three load transmission elements and three actuators. The load transmission elements are adapted to be positioned between upper and lower anterior teeth of the patient and between upper and lower posterior teeth on the left and right sides of the patient's mouth, respectively. The load transmission elements are separated from each other. The actuators are coupled to the load transmission elements, respectively. The controller is configured to control the three actuators to actuate the three load transmission elements individually and sequentially, with a rest period between successive actions of the three load transmission elements, to transmit vibration energy from the three actuators to the patient's periodontal tissues of the anterior teeth, the left posterior teeth, and the right posterior teeth.

A device including one or more preformed or customized eruption guidance appliances placed in an individual's mouth. The preformed appliances are vibrated with a pulsation device to encourage tooth eruption by increasing the force and efficiency of the eruption toward a preferred location and a preferred alignment as well as providing increased blood flow and blood oxygen flow to the muscles and tissues in and around the oral cavity of the individual. The preformed guidance appliance driven by the pulsation device is selected from a range of guidance appliances, each of which is selected by size and shape to fit an individual based on the individuals anticipated tooth and jaw size as well as the growth profile. The pulsation can increase the blood and oxygen flow to the many muscles that surround the appliances outside surfaces that can alter mouth breathing, prevent impingement of the oropharynx from the abnormal distalization of the tongue and mandible during sleep, the proper resting posture of the tongue, increased nasal breathing, prevent snoring, improve abnormal swallowing, correct thumb sucking and various abnormalities of speech.

A device for cranial restructuring, by the expansion, compression, or flexure of a cranial structure located between first and second anchor points, includes: a force generator configured to generate force; a first anchor attachment to the first anchor point; a second anchor attachment to a second anchor point; a hydraulic force transmitting structure, connected to the force generator, to transmit the generated force to the anchors thereby putting the cranial structure in tension, compression or flexure. Another device for cranial restructuring includes: a head support, having a head-receiving portion; a force generator to generate force which is periodic; a first anchor attachment to the first anchor point; a force transmitting structure, connected to the force generator, which transmits the periodic force to the anchor in a restructuring direction; wherein the head support includes: a restriction to prevent or restrict movement of the user's head when the periodic force is applied.

The pulsation can increase the blood and oxygen flow to the many muscles that surround the appliances outside surfaces that can alter mouth breathing, prevent impingment of the oropharynx from the abnormal distalizatin of the tongue and mandible during sleep, the proper resting posture of the tongue, increased nasal breathing, prevent snoring, improve abnormal swallowing, correct thumb sucking and various abnormalities of speech.

A current digital dental model is received that includes a representation of the set of physical teeth for the patient with the current dental appliance attached to the physical teeth or oral cavity. The current digital dental model is a direct digital scan of the set of physical teeth and the current dental appliance. The physical teeth are at a position in treatment when all or a part of the current dental appliance is desired to be removed from one or more of the set of physical teeth and it is desired to use a subsequent appliance. The current digital dental model is created based a new digital dental model that includes the representation of the set of physical teeth without including the current dental appliance.

An orthodontic appliance may include an outer shell having a plurality of cavities shaped to receive the patient's teeth and generate one or more of a force or a torque in response to the appliance being worn on the patient's teeth. The orthodontic appliance may also include an inner structure having a stiffness different than a stiffness of the outer shell. The inner structure can be positioned on an inner surface of the outer shell in order to distribute the one or more of a force or a torque to at least one tooth received within the plurality of cavities.

Described herein is an oral appliance. The oral appliance includes upper and lower trays that each include at least one axial spring configured to contact a palatal/lingual surface of at least one tooth, where each axial spring is coupled to the respective upper or lower tray, and where each axial spring is configured to produce and transmit intermittent, cyclic forces to the palatal/lingual surface of the tooth to promote palatal and upper/lower jaw development. The upper and lower trays each include an expansion mechanism to enable adjustment of the size of the upper and lower trays to account for palatal expansion and upper and lower jaw development. The oral appliance includes first and second adjustable hinge arms that are removably connected to the upper and lower trays so that the oral appliance advances the mandible to provide temporary relief from sleep disordered breathing, sleep apnea and/or snoring.
