Description

Technical Field

[0001] The present application relates to the field of dental implants, and in particular to modular dentures. Background Art

[0002] Dentures are also called false teeth. They are divided into removable dentures and fixed dentures. You should choose the dentures that suit you according to the doctor's instructions. Removable dentures are removable and wearable. After the patient wears the dentures, he or she can take them off when brushing teeth, put them on when eating, take them off when sleeping at night, soak them in water, and put them on when chewing. This is a removable denture. Fixed dentures are glued to the teeth and cannot be taken off or worn. When you go to the hospital, the doctor has already fixed them, so you don't need to take them off. Another type is dental implants.

[0003] The fixing method of fixed dentures is generally to fix a base on the alveolar bone for fixing support and fixing the teeth, and then put the teeth on the base. When putting the teeth on the base, apply special glue on the teeth, and then pass a fixing bolt through the hole opened above the teeth. Use the fixing bolt to fix the teeth and the base together, and finally fill the hole with filling material.

[0004] After the base is fixed to the alveolar bone, glue needs to be applied between the tooth and the base, and then bolts need to be passed through the tooth and the base to fix them, and then the holes through which the bolts are passed need to be filled. This method of fixing the tooth on the base is more cumbersome and inconvenient. Utility Model Content

[0005] The purpose of the present application is to solve the problem proposed in the above-mentioned background technology that after the base is fixed to the alveolar bone, glue needs to be applied between the teeth and the base, and then bolts need to be passed through the teeth and the base for fixing, and then the holes through which the bolts are passed need to be filled. This method of fixing the teeth on the base is relatively cumbersome and inconvenient. The present application provides a combined denture.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] The combined denture comprises a fixed base, a support column is fixed on the fixed base, teeth are arranged on the support column, the teeth are sleeved on the support column, a fixing mechanism is arranged between the teeth and the support column, and a positioning mechanism is arranged between the teeth and the support column.

[0008] By adopting the above technical solution, when the teeth are mounted on the support column, the teeth squeeze the fixing mechanism, and the fixing mechanism fixes the teeth and the support column together. At the same time, when the teeth are mounted on the support column, the positioning mechanism limits the position of the teeth, so that the teeth can be mounted on the support column without deviation, thereby reducing the possibility of troublesome tooth fixing when implanting teeth.

[0009] Furthermore, the fixing mechanism includes two rotating shafts symmetrically connected to the support column, and support plates are fixed on the two rotating shafts. A clamping joint is fixed on the end of the support plate away from the rotating shaft, a clamping groove is opened on the inner wall of the tooth, and an interference component is arranged between the support plate and the support column.

[0010] By adopting the above technical solution, the teeth squeeze the resistance component, the resistance component pushes the support plate to both sides, and then the support plate moves to both sides under the support of the rotating shaft, and then the clamping joint on the support plate is clamped in the clamping groove on the inner wall of the tooth to restrict the tooth, thereby reducing the trouble of fixing the tooth on the fixed base and facilitating the fixation of the tooth.

[0011] Furthermore, the resistance component includes a downward pressure column inserted on the support column, and the two sides of the downward pressure column close to one end of the support column are provided with resistance inclined surfaces, and the two sides of the support column are slidably connected with resistance blocks, which pass through the support column and abut against the inclined surfaces of the downward pressure column.

[0012] By adopting the above technical solution, the teeth squeeze the pressure column, and the pressure column slides on the support column. When the pressure column slides, the resistance inclined surface squeezes the resistance block, and the resistance block moves toward the support plate, thereby facilitating pushing the support plate and allowing the card connector on the support plate to be inserted into the card slot.

[0013] Furthermore, a resistance roller is provided at one end of the resistance block away from the lower pressure column, and the resistance roller is rotatably connected to the resistance block.

[0014] By adopting the above technical solution, the rotatably connected resistance roller on the resistance block resists and pushes the support plate, so that when the resistance block pushes the support plate, the friction between the resistance block and the support plate can be reduced.

[0015] Furthermore, a lower pressing plate is fixed to one end of the support plate close to the rotating shaft, a lower pressing groove corresponding to the lower pressing plate is formed on the inner wall of the tooth, and an inclined surface is formed on one side of the lower pressing groove close to the fixed base.

[0016] By adopting the above technical solution, the teeth press the lower pressure plate, and the lower pressure plate drives the support plate. The support plate rotates under the support of the rotating shaft, so that the clamping joint on the support plate further contacts the clamping groove, thereby further reducing the possibility of movement of the tooth sleeve on the support column.

[0017] Furthermore, a supporting spring piece is arranged between the lower pressing plate and the fixed base, the supporting spring piece is U-shaped, and both ends of the supporting spring piece are fixedly connected to the lower pressing plate and the fixed base.

[0018] By adopting the above technical solution, the supporting spring sheet props up the lower pressure plate, allowing the supporting plate to be close to the supporting column under the support of the rotating shaft, thereby facilitating the placement of the tooth sleeve on the supporting column.

[0019] Furthermore, the positioning mechanism comprises two positioning blocks symmetrically fixed on the inner wall of the tooth, and the support column is provided with two symmetrical positioning grooves, which correspond to the positioning blocks.

[0020] By adopting the above technical solution, the positioning block fixed on the inner wall of the tooth enters the positioning groove, and then the positioning block slides in the positioning groove. The positioning groove restricts the positioning block, thereby reducing the possibility of tooth deviation.

[0021] Furthermore, positioning inclined surfaces are provided on both sides of one end of the positioning block close to the fixed base.

[0022] By adopting the above technical solution, when the tooth is mounted on the support column, the positioning block fixed on the inner wall of the tooth enters the positioning groove under the action of the positioning inclined surface provided on the positioning block, thereby facilitating the positioning block to be inserted into the positioning groove.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the tooth is mounted on the support column, the tooth presses the lower pressure column, and the lower pressure column slides on the support column. When the lower pressure column slides, the contact inclined surface presses the contact block, and the contact block moves toward the support plate. The contact roller rotatably connected to the contact block contacts and pushes the support plate, so that the support plate enters the clamping groove on the inner wall of the tooth with the clamping joint under the support of the rotating shaft. At the same time, the tooth presses the lower pressure plate, and the lower pressure plate drives the support plate. The support plate rotates under the support of the rotating shaft, so that the clamping joint on the support plate further contacts the clamping groove, thereby achieving the purpose of reducing the possibility of trouble in fixing teeth when implanting teeth.

[0025] 2. In the present application, when the tooth is mounted on the support column, the tooth drives the positioning block to approach the positioning groove on the support column, and then under the action of the positioning inclined surface provided on the positioning block, the positioning block fixed on the inner wall of the tooth enters the positioning groove, and then the positioning block slides in the positioning groove. The positioning groove restricts the positioning block so that the positioning block can only move along the direction of the positioning groove, thereby achieving the purpose of reducing the possibility of tooth displacement when the tooth is mounted on the support column.

[0032] The following is combined with Figure 1 —4 Provide further details of this application.

[0033] The embodiments of the present application disclose a modular denture.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The combined denture comprises a fixed base 2, a support column 1 is fixed on the fixed base 2, a tooth 3 is arranged on the support column 1, the tooth 3 is sleeved on the support column 1, a fixing mechanism 4 is arranged between the tooth 3 and the support column 1, and a positioning mechanism 5 is arranged between the tooth 3 and the support column 1. When the combined denture needs to be implanted, the fixed base 2 is first fixed to the alveolar bone, and then the tooth 3 is directly sleeved on the support column 1 on the fixed base 2. When the tooth 3 is sleeved on the support column 1, the tooth 3 presses the fixing mechanism 4, and the fixing mechanism 4 fixes the tooth 3 and the support column 1 together. At the same time, when the tooth 3 is sleeved on the support column 1, the positioning mechanism 5 limits the position of the tooth 3 so that the tooth 3 can be sleeved on the support column 1 without deviation. When the tooth 3 is sleeved on the support column 1 on the fixed base 2, the fixing mechanism 4 directly fixes the tooth 3, thereby reducing the possibility of troublesome fixing of the tooth 3 when implanting the tooth 3.

[0035] Reference Figure 1 , Figure 2 and Figure 3The fixing mechanism 4 includes two rotating shafts 44 symmetrically connected to the support column 1, and support plates 43 are fixed on the two rotating shafts 44. A clamping joint 42 is fixed on the end of the support plate 43 away from the rotating shaft 44. A clamping groove 41 is opened on the inner wall of the tooth 3, and an interference component 45 is arranged between the support plate 43 and the support column 1.

[0036] When the tooth 3 is sleeved on the support column 1, the tooth 3 squeezes the resistance component 45, and the resistance component 45 pushes the support plate 43 to both sides, and then the support plate 43 moves to both sides under the support of the rotating shaft 44, and then the clamping joint 42 on the support plate 43 is clamped in the clamping groove 41 on the inner wall of the tooth 3 to restrict the tooth 3, thereby completing the fixation of the tooth 3. By sleeveing ​​the tooth 3 on the support column 1 and then the tooth 3 squeezing the resistance component 45, the resistance component 45 pushes the clamping joint 42 to be clamped in the clamping groove 41 on the inner wall of the tooth 3, thereby reducing the trouble of fixing the tooth 3 on the fixed base 2 and facilitating the fixation of the tooth 3.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The resistance component 45 includes a downward pressure column 451 inserted into the support column 1, and both sides of the downward pressure column 451 close to the support column 1 are provided with resistance inclined surfaces 453, and both sides of the support column 1 are slidably connected with resistance blocks 452, which penetrate the support column 1 and abut against the inclined surfaces of the downward pressure column 451.

[0038] In addition, a resistance roller 454 is disposed at one end of the resistance block 452 away from the pressing column 451 , and the resistance roller 454 is rotatably connected to the resistance block 452 .

[0039] When the tooth 3 is sleeved on the support column 1, the tooth 3 presses the pressing column 451, and the pressing column 451 slides on the support column 1. When the pressing column 451 slides, the contact inclined surface 453 presses the contact block 452, and the contact block 452 moves toward the support plate 43. The contact roller 454 rotatably connected to the contact block 452 contacts and pushes the support plate 43, so that the support plate 43 brings the clamping joint 42 into the clamping groove 41 on the inner wall of the tooth 3. By using the tooth 3 to press down the pressing column 451, the contact block 452 pushes the support plate 43, so that the clamping joint 42 on the support plate 43 can be easily clamped into the clamping groove 41 on the tooth 3.

[0040] Reference Figure 2 and Figure 3 A lower pressing plate 46 is fixed to one end of the support plate 43 close to the rotating shaft 44 , a lower pressing groove corresponding to the lower pressing plate 46 is opened on the inner wall of the tooth 3 , and an inclined surface 47 is opened on one side of the lower pressing groove close to the fixed base 2 .

[0041] In addition, a supporting spring piece 48 is provided between the lower pressing plate 46 and the fixed base 2 . The supporting spring piece 48 is U-shaped, and both ends of the supporting spring piece 48 are fixedly connected to the lower pressing plate 46 and the fixed base 2 .

[0042] When the tooth 3 is not sleeved on the support column 1, under the support of the supporting spring sheet 48, the supporting spring sheet 48 props up the lower pressure plate 46, so that the support plate 43 is close to the support column 1 under the support of the rotating shaft 44. When the tooth 3 is sleeved on the support column 1 and close to the lower pressure plate 46, the edge of the lower pressure plate 46 abuts against the inclined surface 47, and then enters the lower pressure groove under the restriction of the inclined surface 47. Then the tooth 3 squeezes the lower pressure plate 46, and the lower pressure plate 46 drives the support plate 43. The support plate 43 rotates under the support of the rotating shaft 44, so that the clamping joint 42 on the support plate 43 further abuts against the clamping groove 41. By squeezing the lower pressure plate 46 when the tooth 3 is sleeved on the support column 1, the lower pressure plate 46 drives the support plate 43, and the support plate 43 drives the clamping joint 42 to further abut against the clamping groove 41, the possibility of the tooth 3 sleeved on the support column 1 can be reduced.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The positioning mechanism 5 includes two positioning blocks 51 symmetrically fixed on the inner wall of the tooth 3 , and the support column 1 is provided with two symmetrical positioning grooves 52 , which correspond to the positioning blocks 51 .

[0044] In addition, positioning inclined surfaces 53 are formed on both sides of one end of the positioning block 51 close to the fixed base 2 .

[0045] When the tooth 3 is mounted on the support column 1, the tooth 3 drives the positioning block 51 to approach the positioning groove 52 on the support column 1, and then under the action of the positioning inclined surface 53 provided on the positioning block 51, the positioning block 51 fixed on the inner wall of the tooth 3 enters the positioning groove 52, and then the positioning block 51 slides in the positioning groove 52, and the positioning groove 52 restricts the positioning block 51 so that the positioning block 51 can only move along the direction of the positioning groove 52. By restricting the positioning block 51 fixed on the tooth 3 by the positioning groove 52, the possibility of the tooth 3 being offset can be reduced when the tooth 3 is mounted on the support column 1.

[0046] Working principle: when it is necessary to implant the combined denture, first fix the fixed base 2 and the alveolar bone together, and then directly sleeve the tooth 3 on the supporting column 1 on the fixed base 2. When the tooth 3 is sleeved on the supporting column 1, the tooth 3 drives the positioning block 51 to approach the positioning groove 52 on the supporting column 1, and then under the action of the positioning inclined surface 53 provided on the positioning block 51, the positioning block 51 fixed on the inner wall of the tooth 3 enters the positioning groove 52, and then the positioning block 51 slides in the positioning groove 52, and the positioning groove 52 restricts the positioning block 51 so that the positioning block 51 can only move along the direction of the positioning groove 52, and then the tooth 3 presses the lower pressure column 451, and the lower pressure column 451 is on the supporting column 1. When the column 1 slides and the lower pressure column 451 slides, the contact inclined surface 453 squeezes the contact block 452, and the contact block 452 moves toward the direction of the support plate 43. The contact roller 454 rotatably connected to the contact block 452 contacts and pushes the support plate 43, allowing the support plate 43 to enter the clamping groove 41 on the inner wall of the tooth 3 with the clamping joint 42. At the same time, the edge of the lower pressure plate 46 contacts the inclined surface 47, and then enters the lower pressure groove under the restriction of the inclined surface 47. Then the tooth 3 squeezes the lower pressure plate 46, and the lower pressure plate 46 drives the support plate 43. The support plate 43 rotates under the support of the rotating shaft 44, allowing the clamping joint 42 on the support plate 43 to further contact the clamping groove 41, thereby completing the installation and fixation of the tooth 3.
