Description

Technical Field

[0001] This utility model relates to the field of oral medical equipment technology, specifically a novel front vertical traction headgear. Background Technology

[0002] Mouth-breathing facies, also known as adenoid facies, is a condition caused by nasal obstruction leading to oral breathing, which in turn causes a series of abnormal growth and development. Common changes in the oral and maxillofacial region include: maxillary protrusion, mandibular retrusion and rotation, shallowing or disappearance of the mentolabial sulcus, laxity and eversion of the lip muscles, tension of the chin, and a high and long lower frontal region, among other symptoms. These symptoms affect facial aesthetics and are accompanied by systemic symptoms such as abnormal breathing, snoring, hypoxia, and abnormal posture, which have a significant impact on children's growth and development.

[0003] Mouth-breathing facies is characterized by being easy to prevent but difficult to treat. Clinical findings show that insufficient growth of the mandibular condyle leads to a short mandibular ramus, mandibular posterior rotation, and consequently, a deteriorated facial shape. Traditional treatments attempt to improve mandibular position by promoting condylar growth through traction, but the existing traction headgear has significant mechanical design flaws: the force applied by the current traction headgear is mostly biased posteriorly, which not only fails to correct mandibular posterior rotation but also exacerbates the mandibular downward and backward rotation, further worsening facial convexity and chin shape. Therefore, it is necessary to develop a headgear device that can precisely apply forward and upward traction force, stimulate the growth of the mandibular ramus and condylar region through biomechanical leverage, and guide the mandible to rotate counterclockwise, thereby fundamentally correcting the jaw deformity problem of mouth-breathing facies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel front vertical traction headgear.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel front vertical traction headgear, comprising a headgear body, the headgear body comprising a headgear, a front support sewn to one side of the headgear, and a force-applying end fixedly connected to the lower side of the front support, and a chin pocket sewn to the chin of the headgear, while a chin cutout is provided on the lower side of the headgear.

[0006] As a further description of the above technical solution: The top of the cap is attached to the head with adhesive tape, and the cap is made of non-toxic textile fabric.

[0007] As a further description of the above technical solution: The front front support is symmetrically arranged in two sets, and the two sets of front front supports are respectively fixedly sewn to the left and right sides of the headgear.

[0008] As a further description of the above technical solution: The force-applying end is provided in two sets, and the two sets of force-applying ends are respectively fixed on the front support, and the force-applying end is located at the lower edge of the cheekbone.

[0009] As a further description of the above technical solution: The chin pocket is located on the lower part of the chin, and a hook is provided on one side of the chin pocket.

[0010] As a further description of the above technical solution: One end of the force-applying end is provided with a metal eyelet, and the hook on the chin pocket is connected to the metal eyelet at one end of the force-applying end by a spring rope.

[0011] This utility model has the following beneficial effects: 1. Through the symmetrically set force-applying end and the chin sac elastic traction system, a compound traction force is precisely applied forward and upward. Simulating the principle of biological lever, the traction force is transmitted to the mandibular ramus and condylar region with the temporomandibular joint as the fulcrum. This effectively stimulates the activity of condylar chondrocytes in children in the growth period, promotes the vertical growth of the ramus, and causes the mandible to rotate counterclockwise after continuous traction. This corrects mouth breathing facial features such as mandibular retrusion, mandibular rotation, and chin displacement. In addition, the traction force can moderately expand the temporomandibular joint space, help relieve joint load, and significantly improve the efficiency of jaw deformity correction.

[0012] 2. By using 3D printing light-cured resin to customize the production of the anterior support and chin support, it can perfectly fit the anatomical shape of the patient's face and chin. Combined with the hollow design of the chin, it can avoid soft tissue compression, ensure smooth local blood circulation and shaping space, and enhance the orthodontic effect by using intraoral fulcrums such as TB or jaw pads.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-5 This utility model provides a novel front vertical traction headgear, including a headgear body, the headgear body including a headgear 1, a front support 2 sewn to one side of the headgear 1, and a force-applying end 3 fixedly connected to the lower side of the front support 2, and a chin pocket 4 sewn to the chin of the headgear 1, while a chin cutout 5 is provided on the lower side of the headgear 1.

[0017] In this embodiment, the top of the headgear 1 is attached to the head with adhesive tape, and the headgear 1 is made of non-toxic textile fabric.

[0018] In this embodiment, two sets of front front supports 2 are symmetrically arranged, and the two sets of front front supports 2 are respectively fixedly sewn to the left and right sides of the headgear 1.

[0019] In this embodiment, two sets of force-applying ends 3 are provided, and the two sets of force-applying ends 3 are respectively fixed on the front support 2, and the force-applying ends 3 are located at the lower edge of the cheekbone.

[0020] In this embodiment, the chin pocket 4 is located on the lower part of the chin, and a hook is provided on one side of the chin pocket 4.

[0021] In this embodiment, a metal eyelet is provided at one end of the force-applying end 3, and the hook provided on the chin pocket 4 is connected to the metal eyelet provided at one end of the force-applying end 3 by a spring rope.

[0022] When in use and when worn, the headgear 1, made of non-toxic textile fabric, serves as the basic support structure. It is then securely fixed to the patient's head using adhesive tape. Symmetrically sewn on the left and right sides of the headgear 1 are light-cured resin front supports 2 customized by 3D scanning. The front support 2 extends forward from the lower side to a force-applying end 3 with a length of 20mm. The force-applying end 3 is precisely located at the lower edge of the most prominent part of the cheekbone, offset upward by 5mm and offset towards the midline by 10mm to form a biomechanical lever fulcrum. The end of the force-applying end 3 is equipped with a metal eye ring. The headgear 1 has a 3D-printed chin pocket 4 sewn onto its underside. The chin pocket 4 has traction hooks on both sides, and the headgear 1 has a hollow design corresponding to the chin area to avoid soft tissue compression and promote shape shaping. The hooks of the chin pocket 4 are connected to the metal eye ring of the force-applying end 3 by an elastic traction rope, forming a continuous forward and upward traction force. The traction force acts on the chin and is transmitted to the mandibular ramus and condylar area through the lever principle. During the child's condylar growth potential period, continuous biomechanical stimulation is applied to promote the growth of the mandibular ramus and guide the mandible to rotate counterclockwise, thereby improving mandibular retrusion and reshaping the chin shape. At the same time, the traction force appropriately expands the temporomandibular joint space. Combined with intraoral fulcrums such as TB or jaw pads, the orthodontic effect can be enhanced.

[0023] This utility model discloses a front vertical traction headgear. Through a symmetrically arranged elastic traction system consisting of a force-applying end 3 and a chin support 4, it precisely applies a composite traction force forward and upward. Simulating the principle of biological levers, it uses the temporomandibular joint as a fulcrum to transmit the traction force to the ascending ramus and condylar region of the mandible. This effectively stimulates the activity of condylar chondrocytes in children during their growth period, promotes the vertical growth of the ascending ramus, and causes the mandible to rotate counterclockwise after continuous traction. This corrects mouth breathing facial features such as mandibular retrusion, mandibular rotation, and chin displacement. It can also completely conform to the anatomical shape of the patient's face and chin. Combined with the hollow design of the chin, it avoids soft tissue compression and ensures smooth local blood circulation and shaping space.
