Embodiment Construction

[0018] The device 100 for advancing the lower jaw according to the invention—simplified to its basic structure and with reference to the illustration of the accompanying drawings—is a telescopic element comprising a tube 1 on which a telescopic rod 2 is placed. According to known procedures and therefore not shown in the figures, the tube 1 and the rod 2 can be connected by respective free ends to the same side, the right side or the left side of the upper and lower dental arch of the patient being treated. More specifically, the free ends of the tube 1 and the rod 2 are provided with respective eyelets 10, 20 oriented at predetermined angles with respect to the longitudinal axis of the tube 1 and the rod 2, respectively. The eyelets 10, 20 can be used in a known manner to constrain the device to an orthodontic device comprising two caps or bites anatomically shaped by means of the known prior art A corresponding fixing screw provided by the technology is fitted to the dental ...

Abstract

A device (100) for mandibular advancement, comprising a tube (1) and a telescopic rod (2) associated with the tube (1), in which the tube (1) and the telescopic rod (2) can be associated to the teethof the upper and lower arches, in which the telescopic rod (2) comprises a threaded pin (2P) which engages a female thread (2M) of a hollow element (2T) slidably positioned in said tube (1), and in wherein said hollow element (2T) comprises a maneuvering portion (23) external to the tube (1); the device (100) comprises a friction element (3), arranged between the inner walls (24) of said maneuvering portion and the thread of the pin (2P) and having an outer surface which is complementary to the inner walls (24) of said maneuvering portion and a threaded internal cavity (32) which copies the thread of the pin (2P).

Description

technical field [0001] The present invention relates to devices for mandibular advancement of the type commonly referred to as "Herbst devices" and related methods of manufacture. Background technique [0002] As is known, devices of the above-mentioned type consist essentially of a tube in which a telescopic rod is slidably positioned. The tube and rod are intended to be fixed by their respective free ends to the upper and lower jaws of the patient being treated by means of special joints. The device forces the lower jaw and the teeth in the lower jaw to move forward. [0003] A device of the above type is described in US5879157. Referring to Figure 1 of the accompanying drawings, in a possible embodiment the device comprises a first outer tube EST having corresponding first anchoring eyelets AE and a second tube INT capable of Swipe vertically in EST. The second pipe INT has a manipulating portion MP formed by a ring with an internal nut threadedly engaged by a threade...
