An orthodontic apparatus (1; 10) is designed with at least one orthodontically effective element (4; 12) and at least one holding element (5; 13) for holding the apparatus (1; 10) on the jaw, whereby the apparatus (1; 10) is designed in one piece. In a method for producing an orthodontic apparatus, an electronic data set is produced for a three-dimensional model (2) of a jaw to which the apparatus is supposed to be attached. Further, a virtual positioning of one or more orthodontic elements (4; 12) of the apparatus on jaw model (2) takes place. An electronic data set of a three-dimensional model (3; 11) of the apparatus is subsequently produced. The apparatus (1; 10) is then produced by an additive and/or removal production method according to the data set of the apparatus model.

Certain configurations of methods which can be used to produce removable oral devices are described. In some instances, the removable oral devices can be produced using molding, digital scanning, on demand printing and/or other processes. In certain examples, the produced removable oral device can be used in weight management, athletic performance or in other applications.

An orthopedic appliance including: a base plate, a middle section, a left section, a right section, a dental clasp, a labial bow, an orthodontic spring and an expansion screw. The base plate includes a middle section having a top-front face, a bottom-front face adjacent to the top-front face, a bottom-rear face adjacent to the bottom-front face, and a rear face adjacent to each of the bottom-rear face and the top-front face, wherein the bottom front face includes a ledge which is substantially orthogonal to the primary plane such that the ledge may engage the lower front teeth of a wearer of the appliance.

A dental coupling member related comprises: a first elongated body including, in a first-orientation end region, a first coupling part to be coupled with a first attaching part of a first dental appliance and including, formed in a second-orientation end region, a screwing part; an outer tube including, in a second-orientation end region, a second coupling part to be coupled with a second attaching part of a second dental appliance, and being open at an end on a first-orientation end region side; a third elongated body including a screwed part formed in a first-orientation end region and is inserted into the outer tube in a second-orientation end region of the outer tube, the screwed part being for screwing with the screwing part; and a protrusion projecting from an inner peripheral surface of the outer tube and facing an end surface of the third elongated body on the second-orientation end region side.

The present technology comprises methods of manufacturing an orthodontic appliance. For example, a method can include forming an orthodontic appliance in an intermediate configuration by a casting process. The method can further include securing the appliance to a shape forming fixture such that the appliance assumes a desired configuration. The shape forming fixture can comprise a gingiva portion including a surface having a shape corresponding at least in part to a gingiva of a patient and a securing portion carried by the gingiva portion and configured to releasably secure to a portion of the appliance. The method can further include setting a shape of the appliance while the appliance is secured to the shape forming fixture.

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.
