Description

Technical Field

[0001] The present invention relates to the technical field of orthodontic appliances, and specifically to a simple device for depressing elongated posterior teeth. Background Art

[0002] Clinically, it is common that patients do not repair the missing posterior teeth in the mouth in time due to various reasons. The opposing teeth gradually elongate due to the lack of contact with the corresponding missing teeth, resulting in insufficient occlusal space. In this case, if the patient wants to have a dental implant, orthodontic-restorative combined treatment needs to be used to first restore the restoration space. Therefore, the depression of the elongated teeth becomes necessary.

[0003] There are two common methods for depressing elongated posterior teeth clinically: one is to use the auxiliary arch of fixed orthodontic technology to depress the posterior teeth; the other is to use the method of micro-implant anchorage to assist in depressing a certain elongated posterior tooth.

[0004] Through the above two methods, the elongated posterior teeth can be depressed, but there are also some deficiencies. For example, in the first method, when using other teeth as anchorage during the depression process, it is inevitable that other teeth will move unnecessarily; using the second method, although it can avoid unnecessary movement of other teeth, the implantation of micro-implant anchorage needs to be carried out under local anesthesia, which has surgical trauma, and some patients are unwilling or afraid to accept the implantation of the anchorage nail; and both methods have relatively high requirements for orthodontic clinical technology, long treatment cycles, relatively high treatment costs, and strict requirements for the patient's follow-up visit frequency. Summary of the Invention

[0005] The purpose of the present invention is to provide a simple device for depressing elongated posterior teeth to solve the problems that when using the auxiliary arch of fixed orthodontic technology to use other teeth as anchorage during the depression process, it is inevitable that the surrounding teeth will move unnecessarily, and some patients do not accept the implantation of the anchorage nail in the bone during the operation, etc., reduce the economic burden of the patient, reduce the follow-up visit frequency, and improve the quality of life of the patients.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A simple device for depressing elongated posterior teeth includes a retention and connection device made of a casting metal wrapped with a high molecular elastic material, a high-elastic occlusal pad, a metal retention ring, a connecting rod, and a metal occlusal rest. The high-elastic occlusal pad is connected to the metal retention ring and the occlusal rest through the connecting rod.

[0008] In this technical solution, the metal retention ring and the metal occlusal rest are designed as an integral metal casting according to the shapes of the adjacent teeth on both sides of the missing tooth. The thickness of the retention ring is 2 mm, and the thickness of the occlusal rest is 1 - 1.5 mm.

[0009] In this technical solution, the connecting rod is bent from a 2-mm stainless steel round wire and connected to the metal retention rings on both sides of the occlusal pad.

[0010] In this technical solution, the front and back surfaces of the metal retention rings and the periphery of the connecting rod are wrapped by a layer of polymer elastic material with a thickness of 1-2 mm.

[0011] In this technical solution, the space at the tooth loss position is occupied by the highly elastic occlusal pad and the connecting rod. The occlusal pad is made of polymer elastic material with a thickness of more than 3 mm, and there are device options with different occlusal pad thicknesses.

[0012] With the above device, when the patient bites, when there is a 1-2-mm gap between other teeth and the opposing teeth during occlusion, the elongated posterior teeth first come into contact with the highly elastic occlusal pad. The physiological biting force of the patient is used to apply a longitudinal force to the elongated posterior teeth through the highly elastic occlusal pad, thereby achieving the effect of depressing the elongated posterior teeth.

[0013] As the orthodontic progress changes, if the highly elastic occlusal pad does not first come into contact with the elongated posterior teeth during occlusion, then replace the device with a thicker occlusal pad type to ensure that a longitudinal force can be continuously applied to the elongated posterior teeth during occlusion.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. The present invention is fixed to the teeth through metal retention rings and uses a metal rest stabilizing device. When the patient performs normal occlusal function, the reaction force is transmitted from the highly elastic occlusal pad to the elongated posterior teeth through the patient's own biting force. The continuously applied longitudinal force can effectively improve the depressing effect of the elongated posterior teeth; moreover, the magnitude of the applied force can be self-adjusted by the patient according to their own adaptation situation, the patient's comfort is better, and the occlusal pad has high elasticity, which has a certain buffering and protecting effect on the patient's elongated posterior teeth, as well as tissues such as the muscles and temporomandibular joints involved in occlusal function.

[0016] 2. The present invention can select different thicknesses of highly elastic occlusal pads according to the orthodontic progress and flexible requirements, which can not only better fit the orthodontic progress, reduce the patient's follow-up frequency, but also ensure the health of the dental arch while depressing the elongated posterior teeth.

[0017] 3. The main structure of the present invention is a metal connecting rod and metal retention rings, which have strong rigidity and fatigue resistance. When there are teeth on both sides of the tooth loss area, it has a good effect on depressing 1-3 elongated posterior teeth. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the purpose, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the embodiments and the drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0024] Please refer to Figure 1 and Figure 2 The present invention provides a technical solution: a simple device for depressing elongated posterior teeth, including a retention and connection device 1 made of cast metal wrapped with a polymer elastic material, a high - elastic occlusal pad 2, a metal retention ring 3, a connecting rod 4 and a metal occlusal rest 5. The metal retention ring 3 is connected to the metal occlusal rest 5 through the connecting rod 4.

[0025] Referring to Figure 3 The metal retention ring 3 and the metal occlusal rest 5 are adapted to the adjacent teeth on both sides of the edentulous area, are made of metal casting, and are sleeved on the adjacent teeth on both sides of the missing tooth. At this time, the high - elastic occlusal pad is directly above the elongated posterior teeth.

[0026] Working principle: Referring to Figure 4, in this embodiment, through the patient's own physiological occlusion, when the elongated posterior teeth first contact the highly elastic occlusal pad, no other teeth are in contact with the opposing teeth and there is a clearance space of 1-2 mm; at this time, the highly elastic occlusal pad reacts on the elongated posterior teeth and conducts the longitudinal force to the elongated posterior teeth, so as to achieve the effect of continuously and gently depressing the elongated posterior teeth while protecting the elongated posterior teeth; as the orthodontic progress develops, when the elongated posterior teeth fail to contact the highly elastic occlusal pad first compared with the adjacent teeth, a similar device with a thicker occlusal pad can be replaced for adjustment to ensure that the elongated posterior teeth can be continuously depressed until the correction goal is completed; since the present invention uses the patient's own bite force for depression, the patient himself can adjust the force size according to his own adaptation situation, ensuring that the elongated posterior teeth are depressed with appropriate force while also ensuring the health of the dentomaxillary system.

[0027] The foregoing has shown and described the basic principles, main features, and the advantages of the present invention over the prior art. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
