Description

Technical Field

[0001] This utility model relates to the field of fixed denture technology, specifically to an implantable fixed denture with a clamping ring. Background Technology

[0002] Dental implantology is a new and independent branch of oral science, involving many disciplines within oral science, including oral and maxillofacial surgery, prosthodontics, periodontology, dental imaging, and dental materials. Dental implants, also known as dental implants or artificial tooth roots, are surgically implanted into the upper and lower jawbones at the site of tooth loss. Most current implant-supported fixed dentures are fixed to a mounting base with bolts, and the mounting base is fixed to the alveolar bone with threaded screws. This method does not provide double fixation, and implants are prone to loosening and falling off the mounting base. Therefore, we propose an implant-supported fixed denture with a clamping ring. Utility Model Content

[0003] The purpose of this invention is to provide an implantable fixed denture with a clamping ring to solve the problems mentioned in the background art.

[0005] Furthermore, the clamping assembly includes a bidirectional lead screw disposed within the cavity, with both ends of the bidirectional lead screw connected to bearings disposed on the left and right side walls of the cavity, respectively. Slider blocks are sleeved on the outer walls of both sides of the bidirectional lead screw, and connecting rods are disposed at the bottom of both sets of sliders. Clamping rings are disposed at one end of both sets of connecting rods.

A rotating shaft is disposed at the top of the active bevel gear, and one end of the rotating shaft passes through the bottom of the cavity and the bottom of the implant and is connected to an external adjustment knob. A hexagonal hole is provided at the top of the adjustment knob.

[0006] Furthermore, the top of the dental implant has a slot, and the adjustment knob is located within the slot.

[0007] Furthermore, the bottom of the sealing plate is provided with two sets of sliding grooves, and the two sets of connecting rods are slidably connected in the sliding grooves.

[0008] Furthermore, two sets of guide grooves are provided at the top of the cavity, and each set of sliders is provided with a guide block that matches the guide groove.

[0009] Furthermore, the connecting rod is L-shaped.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please see Figure 1-4 This utility model provides a technical solution: an implantable fixed denture connected with a clamping ring, including alveolar bone 1, the alveolar bone 1 is covered with gingiva 2, a first threaded hole 5 is opened at the top of the alveolar bone 1, a fixing seat 6 is provided above the alveolar bone 1, a threaded pin 4 is provided at the bottom of the fixing seat 6 and threadedly connected to the first threaded hole 5, a second threaded hole 10 is opened at the top of the fixing seat 6, clamping grooves 11 are opened on both the left and right side walls of the fixing seat 6, an implant 3 is provided above the fixing seat 6, a sealing plate 8 is provided at the bottom of the implant 3, a bolt 9 is provided at the bottom of the sealing plate 8 and cooperates with the second threaded hole 10, a cavity 12 is opened inside the sealing plate 8, and a clamping component 7 is provided in the cavity 12.

[0021] Please see Figure 4-5 The clamping assembly 7 includes a bidirectional lead screw 73 disposed within a cavity 12. Both ends of the bidirectional lead screw 73 are connected to bearings disposed on the left and right side walls of the cavity 12, respectively. Slider blocks 74 are sleeved on the outer walls of both sides of the bidirectional lead screw 73. Two sets of guide grooves are formed at the top of the cavity 12. Each set of sliders 74 has a guide block at its top that matches the guide groove. Under the action of the guide grooves and guide blocks, the sliders 74 move more stably on the outer walls of the bidirectional lead screw 73. Each set of sliders 74 has a connecting rod 75 at its bottom, which is L-shaped. The sealing plate 8 has two sets of sliding grooves 77 at its bottom, allowing the two sets of connecting rods 75 to slide within the sliding grooves 77. Next, under the action of the sliding groove 77, the connecting rod 75 moves more stably. Both sets of connecting rods 75 are provided with clamping rings 76 at one end. The clamping groove 11 and the clamping rings 76 are both arc-shaped. The outer wall of the bidirectional screw 73 is sleeved with a driven bevel gear 72. The cavity 12 is provided with a driving bevel gear 71 that meshes with the driven bevel gear 72. The top of the driving bevel gear 71 is provided with a rotating shaft 70. One end of the rotating shaft 70 passes through the bottom of the cavity 12 and the bottom of the implant 3 and is connected to an adjustment knob 78 on the outside. The top of the implant 3 is provided with a slot 13. The adjustment knob 78 is located in the slot 13. The top of the adjustment knob 78 is provided with a hexagonal hole 79.

[0022] Working principle: The dentist cuts open the gum line 2 and then creates a first threaded hole 5 in the alveolar bone 1. The threaded nail 4 is fixed in the first threaded hole 5, and the bolt 9 is threaded into the second threaded hole 10, thereby fixing the implant 3 to the alveolar bone 1. Then, the dentist uses a hex wrench to insert into the hexagonal hole 79 and rotates the adjusting knob 78. The adjusting knob 78 drives the rotating shaft 70 to rotate, which in turn drives the active bevel gear 71 to rotate. The active bevel gear 71 drives the driven bevel gear 72 to rotate, which in turn drives the bidirectional lead screw 73 to rotate. Under the action of the sliding groove 77, the two sets of sliders 74 and the connecting rod 75 move relative to each other. The connecting rod 75 drives the clamping ring 76 to move relative to each other to clamp and fix the clamping groove 11. Then, the groove 13 is filled with filling agent to achieve double fixation of the implant 3.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
