[0037] The following will be described in detail in combination with the accompanying Figure 1 - Figure 6 The present application will be further described in detail.

[0038] The embodiment of the present application discloses a denture bracket.

[0039] Reference Figure 1 - Figure 3 A denture bracket includes a connector 3, the edge of the connector 3 is provided with several arc grooves adapted to the shape of the teeth 2, several teeth 2 are fixedly mounted on the top of the gum 1, and two clasp bodies 4 are provided with threaded holes adapted to the shape of the bolts 8 at one end away from the connector 3, and the positioning holes 7 corresponding to the threaded holes are also adapted to the shape of the bolts 8. The clasp bodies 4 are threaded through the threaded holes by the bolts 8 and then threadedly connected to the corresponding positioning holes 7 and fixedly connected to the denture retention net 6. The two ends of the connecting plate 5 are respectively fixedly connected to the inner center of the two denture retention nets 6, and several positioning holes 7 are opened through the top of the denture retention net 6.

[0040] The clasp body 4 is positioned on the neck of the patient's terminal abutment tooth. The clasp body 4 includes an occlusal support 12 set in the mesial and a clasp A11 set in the distal. The mesial abutment of the clasp body 4 is provided with an indirect retainer 13. The indirect retainer 13 is placed on the mesial abutment occlusal surface of the terminal abutment. The connector 3 is placed on the lingual side of the anterior teeth and 3 mm away from the bottom of the mouth, thereby improving the retention and stability of the denture. The denture retention net 6 is placed on the free end mucosa to facilitate later filling and tooth arrangement.

[0041] Reference Figure 4 - Figure 5 , both ends of the connector 3 are fixedly provided with connectors 9, the connector 9 includes a right-angled trapezoidal block 95, the end of the clamping ring body 4 away from the bolt 8 is fixedly connected to the mounting block 92, the end of the mounting block 92 away from the clamping ring body 4 is fixedly connected to the connecting rod 93, the right-angled trapezoidal block 95 is fixedly connected to the end of the connecting rod 93 away from the mounting block 92, the side of the connector 3 in contact with the clamping ring body 4 is provided with a slide groove 91 that matches the shape of the mounting block 92, and the mounting block 92 is in the slide groove 91. The surface of the cavity side wall in contact with the inner cavity side wall of the slide groove 91 avoids the occurrence of virtual position and prevents the mounting block 92 from shaking in the slide groove 91. The mounting frame 96 is fixedly installed at the inner end of the groove cavity of the slide groove 91. The slot 97 that matches the shape of the right-angled trapezoidal block 95 is opened in the center of the top of the mounting frame 96. The two retaining ring bodies 4 are respectively fixedly connected to the two ends of the connecting rod 93 in the slot 97 through the right-angled trapezoidal block 95. The two weakening grooves 94 are respectively opened at the top and bottom of the connecting rod 93.

[0042] By sliding the mounting block 92, the connecting rod 93 and the right-angled trapezoidal clamping block 95 into the sliding groove one 91, the inclined surface of the right-angled trapezoidal clamping block 95 is stressed during sliding. Through force decomposition, it can be known that the right-angled trapezoidal clamping block 95 and the connecting rod 93 are stressed, the connecting rod 93 is elastically deformed in the weakening groove 94, so that the connecting rod 93 elastically bends downward in the weakening groove 94, so that the mounting block 92, the connecting rod 93 and the right-angled trapezoidal clamping block 95 are completely slid into the sliding groove one 91, and when the mounting block 92 is completely slid into the sliding groove one 91, the right-angled trapezoidal clamping block 95 is clamped in the clamping groove 97, so that the right-angled trapezoidal clamping block 95 and the mounting rack 96 are fixedly connected together, so that the clasp main body 4 and the connecting body 3 are fixedly connected together.

[0043] Referring to Figure 6 , the connecting body 3 is provided with a push rod assembly 10 at the top corresponding to the position of the clamping groove 97. The push rod assembly 10 includes a disc 102 located in the sliding groove two 103 and achieving longitudinal sliding. A through hole matched with the shape of the push rod body 101 is formed in the top center of the disc 102. The push rod body 101 is fixedly installed in the through hole, and the disc 102 is arranged at the position on the top surface of the push rod body 101. The top end of the push rod body 101 movably penetrates the side wall of the connecting body 3 and extends to the top of the connecting body 3. The top end of the push rod body 101 is flush with the top end of the connecting body 3. The bottom end of the push rod body 101 movably penetrates the side wall of the connecting body 3 and extends into the sliding groove one 91, respectively. The bottom end of the push rod body 101 is flush with the top of the inner cavity of the sliding groove one 91. A spring 104 is sleeved on the surface of the push rod body 101 corresponding to the position of the sliding groove two 103. The top end of the spring 104 is fixedly connected to the bottom of the disc 102. The bottom end of the spring 104 is fixedly connected to the bottom of the inner cavity of the sliding groove two 103.

[0044] When it is necessary to detach the clasp main body 4 from the connecting body 3, the push rod body 101 can be pushed by a pushing tool. The push rod body 101 applies a pushing force to the top of the right-angled trapezoidal clamping block 95 to push the right-angled trapezoidal clamping block 95 out of the clamping groove 97. At this time, the connecting body 3 and the clasp main body 4 are no longer fixedly connected together. Then, the mounting block 92, the connecting rod 93 and the right-angled trapezoidal clamping block 95 are slid out of the sliding groove one 91, and the clasp main body 4 is detached from the connecting body 3. Then, the bolt 8 is unscrewed, the clasp main body 4 is detached from the denture retention net 6, and the clasp main body 4 is individually detached and replaced, which is more simple and convenient to operate.

[0045] The implementation principle of the denture support embodiment of the present application is as follows: the mounting block 92, the connecting rod 93 and the right-angle trapezoidal clamping block 95 are slid into the sliding groove one 91, when the mounting block 92 is completely slid into the sliding groove one 91, the right-angle trapezoidal clamping block 95 is clamped in the clamping groove 97, so that the right-angle trapezoidal clamping block 95 and the mounting frame 96 are fixedly connected together, so that the clasp ring body 4 and the connecting body 3 are fixedly connected together, the clasp ring body 4 is fixedly connected with the denture retention net 6 in the corresponding positioning hole 7 through the threaded connection of the bolt 8, when the clasp ring body 4 needs to be repaired due to deformation and fracture, the bolt 8 is first removed from the clasp ring body 4, then the push rod body 101 is pushed, the push rod body 101 pushes the right-angle trapezoidal clamping block 95 out of the clamping groove 97, at this time, the connecting body 3 and the clasp ring body 4 are not fixedly connected together, then the mounting block 92, the connecting rod 93 and the right-angle trapezoidal clamping block 95 are slid out of the sliding groove one 91, and then the clasp ring body 4 is detached from the connecting body 3, then the bolt 8 is unscrewed, the clasp ring body 4 is detached from the denture retention net 6, and then the clasp ring body 4 is individually detached, and the operation is more simple and convenient.

[0046] The above is only an optional embodiment of the present disclosure, and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
