Description

Technical Field

[0001] The utility model belongs to the technical field of full-mouth trays, and in particular relates to a pharyngeal reflex anterior teeth casting post impression tray device. Background Art

[0002] Traditional full-mouth trays and partial trays for anterior teeth are suitable for general diagnosis and treatment patients. However, when performing traditional fixed restoration of anterior teeth in patients with hyperpharyngeal reflex, the traditional tray structure design is popular and the model is single. In addition, impression making for patients with hyperpharyngeal reflex can easily lead to throat irritation, aggravating the fear of operation, greatly increasing the risk of accidental swallowing and aspiration during diagnosis and treatment, and increasing the difficulty of model making and the unit operation time. Therefore, we propose a pharyngeal reflex anterior tooth casting post impression tray device to solve the above problems. Utility Model Content

[0003] The utility model aims to provide a pharyngeal reflex anterior teeth casting post impression tray device, which can reduce the dentition range of the tray for making impressions of anterior teeth casting post fixed restorations for people with hyperpharyngeal reflex on the basis of an ordinary tray design for public use, without affecting the occlusion, and the bottom of the tray is changed to a movable handle, so that the doctor can accurately control the impression range according to the operating tooth position and the adjacent tooth situation when making the impression, and the movable handle can extend out of the mouth after the tray is fixed to assist in fixing the impression position, and reduce the stimulation of the patient's pharyngeal reflex caused by the doctor or the assistant's fingers fixed in the mouth, reduce the risk of swallowing or aspiration during impression making, reduce the unit time of diagnosis and treatment operation, and improve the efficiency of diagnosis and treatment cooperation and the success rate of impression making.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A pharyngeal reflex anterior teeth casting post impression tray device comprises an upper jaw tray and a lower jaw tray, and both the upper jaw tray and the lower jaw tray are connected with a telescopic handle via a plurality of mounting screws, the upper jaw tray comprises a first boss and a first waist-shaped groove, the lower jaw tray comprises a second boss and a second waist-shaped groove, the telescopic handle comprises a first connecting rod and a second connecting rod, and the first connecting rod and the second connecting rod are connected via a telescopic assembly, the side walls on the side opposite to the first connecting rod and the second connecting rod are provided with mounting grooves with openings facing each other, and a buffer assembly is provided between the bottom walls of the two mounting grooves.

[0006] In a preferred embodiment, the telescopic assembly includes a first telescopic rod arranged vertically, and the first telescopic rod is a hollow structure, a second telescopic rod is inserted into the first telescopic rod, a driver is provided in the first telescopic rod, and a gear is connected to the output end of the driver, and a tooth groove meshing with the gear is provided on the side wall of the second telescopic rod.

[0007] In a preferred embodiment, the buffer assembly includes a vertically arranged first buffer rod, and the first buffer rod is a hollow structure. Two symmetrically arranged second buffer rods are inserted into the first buffer rod, and the opposite ends of the two second buffer rods are respectively connected to the bottom walls of the two mounting grooves, and the opposite ends of the two second buffer rods are movably clamped with a first slide plate, and the two first slide plates are connected by a first damping spring.

[0008] In a preferred embodiment, a second slide plate is movably connected to the second telescopic rod, and both ends of the second slide plate are slidably connected to the inner walls of both sides of the first telescopic rod. The second slide plate is connected to the bottom wall of the first telescopic rod through a plurality of second damping springs.

[0009] In a preferred embodiment, the first boss, the first waist-shaped groove, the second boss, and the second waist-shaped groove all adopt a corrugated reinforcement structure.

[0010] In a preferred embodiment, the first boss, the first waist-shaped groove, the second boss, and the second waist-shaped groove are all provided with a plurality of water-permeable holes, and the plurality of water-permeable holes are all provided through the first boss, the first waist-shaped groove, the second boss, and the second waist-shaped groove.

[0011] The technical effects achieved by the utility model are:

[0012] The groove structure extending to the back can effectively reduce the size of the optical parts and can fuse the side and back strength of the metal back plate into one. In terms of production technology, the groove can be used to adjust the limit structure of the mold and control the shape of the back plate. The product can be freely convex or concave, fully ensuring the straightness of the product.

[0013] The waist-shaped groove on the edge connects the reinforcing ribs on the back and the grooves on the side, which are equivalent to the reinforcing ribs on the lower limit. The overall strength of the product is greatly enhanced. The overall boss in the middle can achieve a good match and smooth transition with the plastic back shell, making the product look more natural. More importantly, the application of this boss structure can further strengthen the overall back panel structure, increase the torsional strength of the back panel, increase the anti-sag ability of the back panel, and fundamentally eliminate the pot effect of the back panel. The supporting bosses around are used to support the optical diffuser. Since this structure can raise the position of the diffuser, the edge height around the back panel can be increased, which not only increases the strength around the back panel, but also provides the possibility of locking screws on the side.

[0014] The back panel structure adopts a corrugated reinforcement structure, which not only solves the problem of insufficient strength of the flat metal back panel, but also avoids the problem that the simple reinforced rib back panel cannot satisfy customers in appearance. As a feasible horizontal and vertical reinforcement pattern, it plays a good decorative role in the appearance of the product. The application of the middle convex bulge can not only ensure a smooth transition and perfect fit with the back shell, but also can fundamentally avoid the pot effect of the metal back panel. The groove structure around can easily control the deformation of the product, and the side strength is also well guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS
