[0001] The utility model relates to the technical field of dental instruments, in particular to a protective structure for an alveolar bone defect bone grafting area. Background Art

[0002] The alveolar bone refers to the part of the lower edge of the maxilla and the upper edge of the mandible where the tooth roots are embedded. It is the alveolar process of the maxilla and mandible. It is composed of cortical bone, cancellous bone and intrinsic alveolar bone. It is an important maxillofacial support structure that supports tooth eruption and conducts chewing force. It also has an important influence on stabilizing the shape and function of the dental arch, realizing language, breathing, chewing functions, and maintaining the beauty of the maxillofacial region.

[0003] During the actual treatment of the existing alveolar bone defect area, since the existing protective sheet is installed on the inner wall surface of the alveolar bone defect area, the protective sheet is mostly fixed by parts such as expansion screws, which leads to the inconvenience of replacing the protective sheet during the secondary treatment. It is easy to cause damage to the area around the alveolar bone due to the replacement of screws, thereby affecting the quality of treatment. Utility Model Content

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] like Figure 1-4 As shown, the present embodiment is a protective structure for the bone grafting area of ​​the alveolar bone defect, comprising a protective sheet 1 and a screw 9. A plurality of mounting holes are provided at equal intervals on the edge of the surface of the protective sheet 1, through which mounting buckles 3 are conveniently installed for fixation. A bone grafting groove 2 is provided inside the protective sheet 1, through which bone grafting powder is conveniently filled. The mounting hole of the protective sheet 1 is detachably connected to the mounting buckle 3, and the longitudinal section of the mounting buckle 3 is T-shaped, so that there is a large difference between the top and bottom of the mounting buckle 3, and a through hole is provided inside the mounting buckle 3, and a threaded groove is provided on the top inner wall surface of the through hole, and a screw 5 is connected inside the threaded groove of the mounting buckle 3, as shown in FIG. Figure 3 As described, the screw 5 is divided into two parts, an upper part and an lower part, which are movably limited between the two parts, and mesh with the screw 5 through the threaded groove, thereby driving the clamping component below to change its position and then work. The interior of the mounting buckle 3 is fixedly connected with a spacer 4, that is, the spacer 4 is located in the cylindrical interior of the lower part of the mounting buckle 3 and is fixedly connected, and the middle part of the surface of the screw 5 is inserted into the interior of the surface center of the spacer 4, and the middle and lower positions of the screw 5 are fixed by means of the spacer 4. The bottom surface of the screw 5 is fixedly connected with a number of auxiliary hinge shafts, and each auxiliary hinge shaft is evenly spaced and is hinged to the hinge 8 through the auxiliary hinge shaft, thereby driving the hook 7 by lifting or pressing down.

[0021] Furthermore, the surfaces of several auxiliary hinge shafts on the bottom surface of the screw 5 are respectively hinged with a hinge 8, and the end of the hinge 8 is fixedly connected with a hook 7, which itself has a certain elasticity. The hook 7 is used to clamp the top of the rivet 10, so that the protective plate 1 is installed on the inner wall surface of the alveolar bone defect area.

[0022] Furthermore, a cross-shaped groove is provided on the upper surface of the screw 5, and the top surface of the screw 5 is flush with the surface of the mounting buckle 3. The cross-shaped groove facilitates processing operations by the staff.

[0023] Furthermore, a plurality of steel wires 6 are installed on the lower surface of the spacer 4, and the high and low ends of each steel wire 6 are respectively installed on the lower surface of the spacer 4 and the tail of the hook 7. The tail of the hook 7 is limited by the steel wire 6, which can promote the realization of a high and low effect and prevent the tail of the hook 7 from falling.

[0024] Furthermore, the screw 9 is installed on the inner wall surface of the alveolar bone defect area, and a rivet 10 is installed on the top surface of the screw 9. Most of the screw 9 needs to enter the alveolar bone, and the rivet 10 itself is a polygon and needs to be exposed outside.

[0025] Furthermore, the diameter of the rivet button 10 is smaller than the bottom diameter of the mounting button 3, and the position of each rivet button 10 overlaps with the mounting hole opened on the surface of the protective sheet 1. The rivet button 10 overlaps with the mounting hole, thereby facilitating the installation of the protective sheet 1.

[0026] The method of using this embodiment is: when using, please refer to Figure 1-4 , first, the staff needs to manually drill holes on the inner wall surface of the patient's alveolar bone defect area so that the screws 9 can be installed on the inner wall surfaces around the patient's alveolar bone defect area. At the same time, when installing the screws 9, the screws 9 are installed in the pre-drilled holes, and then the protective sheet 1 is covered on the inner wall surface of the patient's alveolar bone defect area, and the mounting holes opened at the edge of the surface of the protective sheet 1 are kept consistent with the position of the rivet 10, and then the mounting buckle 3 is filled and installed along the edge of the surface of the protective sheet 1. During installation, the staff manually rotates the screw 5 on the surface of the mounting buckle 3 with the help of tools, and uses the rotation of the screw 5 to synchronously move downward inside the mounting buckle 3, and uses the downward movement of the screw 5 to press down the surface of the hook 7, and the hook 7 contacts with the rivet 10 below and elastically deforms, and the hook After 7 expands outward, the bottom of the hook claw 7 is no longer tightened by the rivet buckle 10 but is elastically reset, so that several hook claws 7 grab the rivet buckle 10 at the same time, and then the staff drives the screw 5 to reverse and reset, thereby losing the tightening effect on the hinge 8. Under the influence of the steel wire 6, the height of the end of the entire hook claw 7 becomes lower and lower, and the rivet buckle 10 is gripped tighter and tighter, so that the tail of the hook claw 7 is completely fixed to the surface edge of the rivet buckle 10, and then the staff fills the bone grafting groove 2 with bone grafting powder, so as to facilitate the installation of the denture. It should be noted that the size and thickness of the mounting buckle 3 need to be designed to be smaller to reduce the discomfort caused to the human body by the thickness, and the steel wire 6, spacer 4, etc. are all in the mounting buckle 3, and their stability will not be affected by external forces such as the patient's tongue. The subsequent disassembly only requires continuous downward rotation of the screw 5 to push the hook claw 7 downward.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
