[0002] Dentures are what people often call "false teeth", and full dentures are devices that consist of artificial teeth embedded in a base and placed in the mouth. Full dentures are a conventional restorative treatment method for edentulous patients.
[0003] Full dentures are removable prostheses that use artificial materials to replace missing maxillary or mandibular complete dentition and related tissues. However, dentures need to go through a series of actions such as frequent wearing, removal, and oral occlusion during use. The existing full denture materials and structures are relatively simple, and the fixation of dentures in the mouth is prone to slippage, affecting the user's use; although it meets the oral comfort level; but when biting an object, the denture parts, which are two parts of each other, cannot be used normally under high-intensity biting actions, and the biting surfaces of the two are easily misaligned, resulting in a poor user experience and limited biting strength.
[0004] Moreover, existing complete dentures generally only use magnets of the same polarity to repel each other to improve adhesion. Obviously, this is only an auxiliary means and its effect is not significant. Utility Model Content
[0005] The purpose of the utility model is to provide a complete denture, which can solve the problems raised by the above-mentioned background technology in view of the shortcomings of the prior art.

[0027] Example 1
[0028] like Figure 1 , Figure 2As shown, the utility model provides a complete denture, including bases 1 arranged in pairs and installed on the alveolar ridge, and artificial teeth 4 that match each other are provided on the opposite end faces of the two bases 1, and the artificial teeth 4 is composed of a plurality of tooth units, one of the bases 1 is provided with a mounting body 2 at both ends, and a rotating body 3 is rotatably provided on the mounting body 2; the other base 1 is provided with locking holes adapted to the rotating body 3 at both ends; a telescopic part is provided at the end of the rotating body 3; the axis of the rotating body 3 is coaxial with the axis of the locking hole; the telescopic part extends along the axis of the rotating body 3 into the locking hole, and a locking member for locking the telescopic part is provided in the locking hole. The full denture provided by the present technical solution is aimed at the upper and lower bases 1 of the denture in the prior art being separated from each other; the two denture components in the full denture are two independent parts, and when biting an object, the denture parts that are two parts of each other are in a high-intensity biting action, and the occlusal surfaces of the two parts are easily misaligned, resulting in a poor user experience and limited bite strength; in order to solve the above problems, the present technical solution provides two bases 1 that are respectively adapted to the upper jaw or lower jaw of the user, and the artificial teeth 4 are installed on the end surfaces of the two bases 1 that match each other, and the artificial teeth 4 are installed on the end surfaces of the two bases 1 that match each other. The support of the dentition 4 on the base 1 is in accordance with the alveolar ridge of the user, so as to improve the biting force of the user on the object by using the artificial dentition 4 (made of a relatively strong material); and a mounting body 2 formed integrally with the base 1 located at the upper jaw is embedded, the mounting body 2 is tiltedly arranged on the base 1, and a part of the mounting body 2 protrudes outward from the base 1, and an antibacterial material is sprayed on the surface of the mounting body 2; and a rotating body 3 is arranged on the free end of the mounting body 2 by rotating the pin, and the angle between the two is an acute angle, and the structure is used to The structure realizes the connection of two bases 1 matching the upper jaw and the lower jaw in the oral cavity and guides the movement of the two bases 1; the specific installation steps are: when installing, first assemble the base 1 matching the upper jaw on the upper jaw; at this time, the rotating body 3 is fixed relative to the mounting body 2; the angle between the two is an acute angle; then the base 1 matching the lower jaw is inserted into the user's mouth, at this time, because the base 1 matching the lower jaw enters the oral cavity, the end of the lower jaw does not contact the rotating body 3 until it matches the lower jaw. After the base 1 is assembled, the axis of the rotating body 3 is coaxial with the axis of the locking hole, so that the telescopic part 7 installed on the rotating body 3 is gradually moved into the locking hole and locked under the guidance of the locking piece; the two separated bases 1 are connected into a whole by utilizing the mutual cooperation between the mounting body 2 and the rotating body 3 and the locking of the telescopic part 7 by the locking piece, thereby improving the integrity of the two in the user's mouth, avoiding the mutual misalignment of the two bases 1, improving the occlusal accuracy of the complete denture, and improving the convenience of connecting the two bases 1.
[0029] In some technical solutions of the present utility model, such as Figure 2 , Figure 3As shown, the end of the base 1 is provided with a guide groove 11 connected to the locking hole, and the center line of the guide groove 11 is coaxial with the axis of the locking hole. The guide groove 11 is a through groove with an open top wall; and after the base 1 adapted to the mandible enters a certain position in the oral cavity, the telescopic part 7 slidably arranged in the rotating body 3 is partially placed in the guide groove 11, and abuts against the inner bottom wall of the guide groove 11 and slides along the opening direction of the guide groove 11. While the base 1 gradually enters the oral cavity, the telescopic part 7 gradually approaches the locking hole under the guidance of the guide groove 11, until the base 1 adapted to the mandible is assembled, at which time the axis of the rotating body 3 is coaxial with the axis of the locking hole, and the telescopic part 7 is embedded in the locking hole, and the telescopic part 7 is locked by the locking member. The telescopic part 7 is guided by the above structure to ensure that the telescopic part 7 can be smoothly inserted into the locking hole, thereby improving the installation accuracy of the device.
[0030] In some technical solutions of the present utility model, such as Figure 4 As shown, the telescopic part is a locking rod, and the locking rod is inserted into the rotating body 3. The locking rod can slide freely in the slideway opened in the rotating body 3, and the friction coefficient between the outer wall of the locking rod and the slideway is small. A limit spring 8 connected to the locking rod is provided in the slideway to provide a reverse thrust for the movement of the locking rod, and in the initial state, the locking rod will not slide freely in the rotating body 3, causing the device to fail to operate normally.
[0031] In some technical solutions of the present utility model, the locking member is a first magnetic pole 13, and a second magnetic pole 6 is embedded in the locking rod and is magnetically connected to the first magnetic pole 13. Both the first magnetic pole 13 and the second magnetic pole 6 are strong magnetic poles, and the locking rod can be magnetically attracted to the locking hole by the suction force of the magnetic poles and the reaction force of the limit spring 8 to prevent the locking rod from slipping out of the locking hole.
[0032] In some technical solutions of the utility model, an expansion member 9 for expanding the angle between the rotating body 3 and the mounting body 2 is provided; the expansion member 9 is a torsion spring, one end of which is connected to the mounting body 2, and the other end of which is connected to the rotating body 3. The expansion member 9 can keep the angle between the rotating body 3 and the mounting body 2 acute; the rotating body 3 is relatively fixed on the mounting body 2; and the problem that the rotating body 3 rotates at will and the telescopic part 7 installed on the rotating body 3 cannot be adapted to the locking hole occurs.
[0033] Furthermore, the torsion spring can apply a reverse thrust to the rotating body 3 and the mounting body 2, that is, apply a force in the opposite direction to the two bases 1 respectively adapted for the upper jaw and the lower jaw, thereby holding the two bases 1 against the alveolar ridge, thereby increasing the stability of the user when using the complete denture.
[0034] In some technical solutions of the utility model, a sealing telescopic sleeve 14 is further included; one end of the sealing telescopic sleeve 14 is connected to the rotating body 3; a closing body 10 adapted to the guide groove 11 is provided on the side of the sealing telescopic sleeve 14 away from the rotating body 3, and a part of the closing body 10 is embedded in the guide groove 11; the telescopic part passes through the sealing telescopic sleeve 14 and the closing body 10 and extends outward. The provided sealing sleeve can cover the gap between the rotating body 3 and the telescopic part, and the provided closing body 10 can cover the guide groove 11, so as to avoid dirt and grime between the two, and breed bacteria, which is not conducive to later cleaning.
[0035] Furthermore, the sealing rope sleeve 14 is provided in a bellows shape, and an O-ring can also be used to replace the sealing telescopic sleeve 14.
[0036] In some technical solutions of the utility model, a bonding sheet 5 that fits the inner wall of the oral cavity is provided on the inner arc surface of the base 1. The provided bonding sheet 5 is a film-shaped colloid with a certain toughness, which can better fit the inner wall of the oral cavity, thereby better fixing the base 1 in the oral cavity to prevent the two from falling off.
[0037] In some technical solutions of the present utility model, such as Figure 6 As shown, a plurality of clamps 15 adapted to the alveolar ridge are equidistantly arranged in the mounting groove of the base 1 adapted to the alveolar ridge. The clamps 15 are U-shaped spring sheets, and the two vertical sections of the clamps 15 are inclined and close to each other. The clamps 15 are embedded in the base 1, and the base 1 and the clamps 15 are integrally formed, so that the rigidity of the base 1 can be increased, the mutual bite strength of the two bases 1 when the device is used can be increased, and the service life of the base 1 can be improved.
[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
