Description

Technical Field

[0001] The utility model relates to the technical field of oral medical auxiliary instruments, in particular to a prefabricated space maintainer. Background Art

[0002] In oral medicine, if timely measures are not taken after tooth loss, the adjacent teeth may move toward the missing side due to loss of support, causing the gap to become smaller and affecting the neatness of the tooth arrangement. Traditional space maintainers need to be sent to the factory for processing and production, which has a long production cycle and is not easy to adjust according to the patient's specific situation. In addition, traditional prefabricated retainers may be at risk of falling off or being swallowed accidentally during use.

[0003] Therefore, developing a new type of prefabricated space maintainer is of great significance to improving dental treatment efficiency and patient experience. Utility Model Content

[0004] The purpose of the utility model is to solve the problems mentioned in the background technology, and provide a prefabricated gap maintainer, including a fixing member, a bolt channel is provided at the end of the fixing member, and a limit plate is provided in the bolt channel;

[0005] A stop ball is provided at the top of the bolt channel to limit the forward movement of the limit plate;

[0006] The end of the limiting plate extending out of the bolt channel is provided with an arc-shaped contact surface which matches the surface of the front teeth.

[0007] As a preferred solution, the fixing member is a band ring or a metal crown.

[0008] As a preferred solution, an anti-slip structure is provided on the inner side of the fixing piece to increase the friction between the fixing piece and the teeth and prevent it from sliding or falling off during use.

[0009] As a preferred solution, the fixing member is provided with an indicator mark for marking the patient's personal information or the usage direction of the retainer.

[0010] As a preferred solution, the fixing member and the limiting plate are both made of biocompatible materials to reduce irritation and discomfort to oral tissues.

[0011] Compared with the prior art, the advantages of the utility model are: simple structure and easy to use; by cutting limit plates of different lengths, precise control of the gap can be achieved to adapt to the specific conditions of different patients; it does not need to be sent to the factory for processing and production, but can be produced on-site according to the specific conditions of the patient, thereby shortening the treatment cycle; due to the effect of the stop ball, the limit plate can only be pulled out backwards and cannot be pulled out forwards, thereby preventing the risk of accidental swallowing caused by the fall of the front teeth and the fall of the limit plate; the fixing part can be selected with a ring or a metal crown, which can flexibly adapt to the needs of different patients, and the inner side of the fixing part or the metal crown is a grid-like rough surface, which increases the friction between the teeth.

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0019] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of the embodiments of the present invention, "multiple" means at least 2.

[0021] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] In conjunction with the accompanying drawings, a prefabricated space maintainer includes a fixing member 1, a bolt channel 2 is provided at the end of the fixing member 1, a limit plate 4 is provided in the bolt channel 2; a stop ball 3 is provided at the top of the bolt channel 2 to limit the forward movement of the limit plate 4;

[0023] The end of the limiting plate 4 extending out of the bolt channel 2 is provided with an arc-shaped contact surface 5 which matches the surface of the front teeth.

[0024] The fixing member 1 is a band ring or a metal crown. An anti-slip structure is provided on the inner side of the fixing member 1 to increase the friction between the fixing member 1 and the teeth to prevent it from sliding or falling off during use. An indicator mark is provided on the fixing member 1 to mark the patient's personal information or the direction of use of the retainer. The fixing member 1 and the limiting plate 4 are both made of biocompatible materials to reduce irritation and discomfort to oral tissues.

[0025] During the specific implementation of the utility model, the fixing part is fixed on the patient's teeth, and a limit plate of appropriate length is cut according to the needs, and then the limit plate is inserted into the limit plate groove in the bolt channel, so that the arc contact surface of the limit plate matches the surface of the front teeth. By adjusting the length of the limit plate, the gap can be accurately controlled to prevent the back teeth from moving forward. Due to the effect of the stop ball, the limit plate can only be pulled backward and cannot be pulled forward, thereby preventing the risk of swallowing due to the fall of the front teeth and the fall of the limit plate.

[0026] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention of the utility model, they can creatively design a structure and embodiment similar to the technical solution, which should belong to the protection scope of the utility model.
