Embodiment Construction

[0018] The device 100 for advancing the lower jaw according to the invention - simplified to the basic structure of the device 100 and with reference to the illustration of the drawings - is a telescopic element comprising a tube 1 in which a telescopic rod 2 is placed. According to a known procedure and therefore not shown in the figures, the tube 1 and the rod 2 can be connected by their respective free ends to the same, right or left side of the upper and lower dental arches of the patient being treated. More specifically, the free end of the tube 1 and the free end of 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 confine the device to an orthodontic device comprising two caps or bite pieces anatomically shaped by means of known prior art. The technology provides the fitting of corresponding fixing scre...

Abstract

A device (100) for mandibular advancement, the device (100) comprising a tube (1) and a telescopic rod (2) associated with the tube (1), wherein the tube (1) and the telescopic rod (2) can Connected to the teeth of the upper and lower arches, wherein the telescopic rod (2) consists of a threaded pin (2P) which engages with a female part of a hollow element (2T) slidably positioned in the tube (1) The thread (2M) engages, and wherein said hollow element (2T) comprises a manipulation part (23) outside the tube (1), the device (100) comprises a friction element (3) arranged on the inner wall of the manipulation part ( 24 ) and the threads of the pin ( 2P ) and the friction element has an outer surface complementary to the inner wall ( 24 ) of said manipulating portion and an internally threaded cavity that emulates the threads of the pin ( 2P ).

Description

technical field [0001] The present invention relates to a device for mandibular advancement of the type commonly referred to as a "Herbst device" and an associated method of manufacture. Background technique [0002] As is known, devices of the type mentioned above consist essentially of a tube in which a telescopic rod is slidably positioned. The tube and rod are intended to be fixed to the upper and lower jaws of the patient being treated by means of special joints through their respective free ends. 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 FIG. 1 of the accompanying drawings, in a possible embodiment, the device comprises a first outer tube EST and a second tube INT, the first outer tube EST has a corresponding first anchoring hole AE, and the second tube INT can be inserted into the outer tube Sliding vertically in EST. The second tube INT has a manipu...
