A method for generating and fabricating a dental device having a body. The body may have a first plurality of tooth receiving cavities shaped to receive teeth of a first side of an arch. The body may also have a second plurality of tooth receiving cavities shaped to receive teeth of a second side of an arch. A palatal portion may extend between the first plurality of tooth receiving cavities and the second plurality of tooth receiving cavities. The palatal portion may be shaped to apply an expansion force to the teeth of the first side of the arch and the teeth of the second side of the arch. The palatal portion may include a plurality of bands that extend between the first plurality of tooth receiving cavities and the second plurality of tooth receiving cavities, each respective band may have a respective different thickness.

The orthodontic appliance includes a spread plate for spreading location of right and left molars of an upper dentition portion by spreading right and left plate portions, and the right and left plate portions include plate body portions arranged respectively on the sides of the molars of the upper dentition portion and the engagement portions extending from the plate body portions to the positions each facing the vicinity of the front teeth of the upper dentition portion, and the engagement portions are configured to be engaged with the lower front teeth when the upper dentition portion and a lower dentition portion are engaged with each other.

Mandibular advancement devices (MAD) are disclosed comprising an upper splint, a lower splint, and at least one sensor, wherein the sensor measures a biological or biophysical aspect of a patient. Methods of using the devices are also disclosed.

In some embodiments, apparatuses and methods are provided herein useful to orthodontic appliances. In some embodiments, an orthodontic appliance comprises a main body portion including a first end and a second end, wherein the first end is opposite the second end, the main body portion comprising a first orthodontic device, wherein the first orthodontic device is configured to be bonded to a first tooth of a patient's mouth, and wherein the first orthodontic device is located to proximal the first end, and an eyelet, wherein the eyelet is located proximal to the second end, and a second orthodontic device, wherein the second orthodontic device is configured to be bonded to a second tooth of the patient's mouth, wherein the second orthodontic device includes a protrusion, and wherein the protrusion is located within the eyelet during use in the patient's mouth.

The present invention provides adjustment means for a mandibular advancement device. The device includes both intraoral and extraoral portions. The intraoral portion includes a body portion. The body portion includes lower and upper plates. The lower plate is adapted to accommodate a pair of opposed arms that extend rearwardly and outwardly from the plate into the oral cavity when the device is worn. Each arm includes a posterior intraoral maxillary abutment surface. The lower plate includes a threaded hole on each side, adjacent a respective arm so that the threaded hole extends from the respective arm towards the edge of the plate. Each hole is adapted to receive a screw that is able to be screwed into the threaded hole, and when the screw has been sufficiently screwed, the inner end of the screw contacts its respective arm whereupon further turning of the screw forces the arm to move towards its opposite arm so that the position of the moved arm's posterior intraoral maxillary abutment surface is moved to a new position.

A coupling member includes a sliding member and a sleeve. The sliding member has one axial direction end portion coupled to a first attachment portion provided at a first attachment that is mounted to one of a maxilla or a mandible. The sleeve has one axial direction end portion coupled to a second attachment portion provided at a second attachment that is mounted to the other of the maxilla and the mandible. The sliding member is inserted into the sleeve so as to be slidable. A restricting section is formed at the sleeve between two axial direction end portions of the sleeve so as to restrict sliding of the sliding member in both directions along an axial direction of the sliding member.
