Embodiment Construction

[0042] first go to figure 1 , where an isometric view of the top of the base plate 1 is shown. The base plate 1 is a part of the main body part inside the oral cavity of the mandibular advancement device. The base plate 1 includes a pair of arms 3 and 3', respectively. Each of arms 3 and 3' enters rearwardly into the wearer's mouth. In the preferred embodiment, each arm is integrally formed in the base plate at 5 and 5' respectively. Each of the arms 3 and 3' is made of a suitable elastic material which will yield elastically under the influence of external forces. Each arm rests in its most extended position relative to its opposing arm when no external force is applied.

[0043] Adjacent to each arm is a threaded hole 7 and 7' respectively. Each hole is reset from the edge of the base plate 1 and each hole is located substantially centrally in the respective slot 9 and 9'. Each threaded hole 7 and 7' is open at its innermost end.

[0044] Each arm 3 and 3' also has a ...

Abstract

An adjustment member for a mandibular advancement device is provided. The device includes an oral interior and an oral exterior. The oral cavity interior includes a body portion. The main body part comprises a lower plate and an upper plate. The lower plate is adapted to receive a pair of opposing arms that extend rearward and outward from the plate into the oral cavity when the device is worn. Each arm includes a posterior intra-oral posterior maxillary abutment surface. The lower plate includes a threaded hole on each side adjacent the respective arm such that the threaded hole extends from the respective arm toward an edge of the plate. Each bore is adapted to receive a screw that can be screwed into the threaded bore, and when the screw has been sufficiently screwed in, the inner end of the screw contacts its respective arm, whereupon further rotation of the screw forces the arm to move towards its opposite arm, such that the position of the posterior oral posterior maxillary abutment surface that moves the arm moves to a new position.

Description

technical field [0001] The present invention relates to mandibular advancement devices, in particular to devices worn by a person to prevent obstructive sleep apnea, and in particular to adjustment components for the interior of the oral cavity for such devices. Background technique [0002] Mandibular advancement devices of the type mentioned in this specification have been disclosed in WO 2019 / 071291 A1 and WO 2006 / 072147. The disclosed mandibular advancement device has an oral interior and an oral exterior. The invention primarily relates to the interior of the oral cavity of the device. [0003] Due to the wide variation in the size and shape of the mouths of users of these types of devices, and in order to keep manufacturing costs low, these devices are manufactured in three wide sizes, such as small, medium and large. However, further adjustments within each of these wide dimensions are required to maximize comfort and fit for each particular user, and also to maximi...
