Description

Guide plate for anchorage nail implantation positioning
Technical Field
The utility model relates to the field of oral treatment, in particular to the technical field of orthodontic treatment, and particularly relates to a guide plate for implanting and positioning an anchorage nail.
Background
In orthodontic treatment, it is necessary to assist in adjusting the abnormal jaw-misalignment between the facial jawbone, teeth and maxillofacial nerves and muscles, that is, between the upper and lower jawbone, between the upper and lower teeth, between the teeth and the jawbone, by various auxiliary devices such as implant anchorage nails, and the final correction aims at achieving the balance, functional stability and aesthetic effect of the oromandibular system.
For orthodontic correction treatment, in order to enable the anchorage nail to exert an effective anchorage effect, accurate implantation positions and implantation angles are indispensable essential factors. However, implant sites have extremely complex anatomy, including roots, maxillary sinuses, cortical thickness, inferior alveolar nerves, blood vessels, osteoporosis, and the like. Therefore, orthodontists need to make detailed evaluations and measurements of the implant location and angle of the anchorage prior to implantation of the anchorage. Although in clinic 3D imaging can give a certain reference assistance to the implantation position of the anchorage nail, in actual clinical implantation treatment, due to the limited oral operation space and view angle, it is difficult for a clinician to accurately operate the anchorage nail according to the implantation point and implantation angle according to the treatment plan without guidance. Therefore, in the process of implanting the anchorage nails, the problems of injury to tooth roots, maxillary sinuses, nerves and the like easily occur, and secondary injury and other adverse conditions are caused. Therefore, it is important to precisely implant the branch pin into a predetermined jawbone or alveolar bone.
The application document with the application number of CN110946663B discloses an improved guide plate for planting micro-implant nails, which comprises a tooth surface retention plate, a gum retention plate, micro-implant nail implantation holes and a handle guide tube. The dental surface retention plate comprises a far-middle dental surface retention plate and a near-middle dental surface retention plate which are spliced, and a splice line of the far-middle dental surface retention plate and the near-middle dental surface retention plate is positioned at the center of the implantation position of the micro-implant nail of the patient; the gum retention plate comprises a spliced far gum retention plate and a spliced near gum retention plate, and a spliced line of the far gum retention plate and the spliced near gum retention plate is positioned at the center of the implantation position of the micro-implant nail of the patient; the micro-implant nail implantation hole is formed in the spliced line of the far-middle gum retention plate and the near-middle gum retention plate, the micro-implant nail implantation hole is positioned in the micro-implant nail implantation position of the patient, and the center of the micro-implant nail implantation hole is positioned in the spliced line; the handle guide pipeline is arranged on the micro-implant nail implantation hole, and the angle between the handle guide pipeline and the tooth surface retention plate is adapted to the implantation angle of the micro-implant nail of the patient; the handle guide pipeline and the micro-implant nail implantation holes are cylindrical cavities and are coaxially arranged; the handle guiding pipeline is used for guiding the micro-implant and the implantation direction of the implantation handle.
The application divides the micro-planting nail guide plate into two parts, and only solves the problem that the guide plate is difficult to take out and separate after the micro-planting nails are planted. However, the implantation requirements of the anchorage nails are severe, strict accurate requirements are provided for implantation angles and implantation points, and as the implantation guide plates of the anchorage nails are respectively formed by embedding the two guide plates in the near and far directions, the retention stability is poor, the clinical operation is complex, the implantation points and the implantation angles of the anchorage nails are easy to deviate due to small oral cavity space and large operation limitation, and the handle guide tube of the application is of a solid columnar structure, a certain solid height is needed, so the free implantation depth of the anchorage nails is obviously limited, in addition, the anchorage nails have the possibility of cutting the tube wall in the rotary implantation process, and the risk of healing failure after the anchorage nails are implanted is improved.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model aims to provide a guide plate for implanting and positioning an anchorage nail, which has the advantages of accurate positioning of an implantation point and an implantation angle, is stable and is convenient to detach.
In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.
The utility model provides a guide plate for implanting and positioning an anchorage nail, which has a specific structure shown in figure 1 and comprises the following components: the integral type anchorage nail location template 1, angle adjustment portion 2, crack separation face 3, locating hole 4 and angle limiting hole 5. The anchorage nail positioning template 1 takes the positioning hole as the center to cover up and down, is suitable for the turning part of the labial and buccal sulcus and a plurality of clinical dental crowns, takes the positioning hole as the center to cover left and right, and expands left and right to the width of a plurality of clinical dental crowns, so that the template has proper stability; the positioning hole 4 and the angle limiting hole 5 are matched with the diameter of the corresponding standard anchorage nail or larger by about 1 mm.
The anchorage nail positioning template 1 is provided with positioning holes 4.
The angle adjusting part 2 is fixedly connected with the anchorage nail positioning template 1, and an angle limiting hole 5 is arranged on the angle adjusting part 2.
The guide plate is provided with a crack separating surface 3, and the locating hole 4 and the angle limiting hole 5 are positioned in the crack separating surface in a straight line.
In the specific use process, the anchorage nail implantation positioning point and the implantation angle can be used for completing the manufacturing through the establishment of a 3D design by means of an oral cavity dentition model and an imaging auxiliary reference. The planting precision of the personalized design guide plate is higher, and personalized design is recommended. During the clinical implant of the anchorage nail, the anchorage nail sequentially passes through the angle defining hole and the positioning hole, thereby determining the implantation point and the implantation angle, and then the anchorage nail is implanted into the alveolar bone. The accuracy of the implantation of the anchorage nail is higher due to the certainty of the anchorage nail positioning template, the angle limiting hole and the positioning hole.
The crack separating surface is arranged on the anchorage nail implantation positioning guide plate, and the anchorage nail can be taken down by splitting the anchorage nail implantation positioning guide plate towards two sides after the anchorage nail implantation is completed. In order to detach the anchorage nail implantation positioning guide plate more conveniently, the application is provided with separating handles on two sides of the angle adjusting part respectively, as shown by 6 in fig. 1. In detaching the guide plate for implantation positioning of the anchorage nails, the guide plate can be easily detached by means of two detaching handles 6. The separating handle 6 in fig. 1 is of a rectangular parallelepiped structure, and the separating handle 6 may be designed in virtually any shape that can be used for separating a guide plate.
In order to increase the stability of the initial stage of the implantation of the anchorage nail, the angle adjusting part 2 is designed to be a hollow structure, the hollow structure is fixedly connected with the anchorage nail positioning template 1 through the side surface of the hollow structure, and the anchorage nail positioning template 1 and the angle adjusting part 2 are usually made of transparent materials or non-transparent materials.
After the anchorage nail passes through the angle limiting hole 5, the angle of the anchorage nail needs to be adjusted in the angle adjusting part 2 so as to smoothly pass through the positioning hole 4, and the anchorage nail implantation operation is performed. The angle adjusting part 2 is provided with the fenestration, so that a more favorable visual field is provided for clinical treatment, and the operation of adjusting the angle of the anchorage nail can be quickly realized. The fenestration may be disposed on the upper and lower surfaces corresponding to the surfaces of the angle defining aperture 5 and the positioning aperture 4, and the fenestration area may be smaller than or equal to the upper and lower surfaces, preferably equal, i.e., the fenestration is maximized.
The up-down window can reduce the resistance of separating the support nail from the left and right to implant the guide plate for positioning.
In order to provide a better view, the windows may also be provided on the left and right faces corresponding to the faces of the angle defining holes 5 and the positioning holes 4, and this is a preferred way to increase the efficiency and accuracy of the positioning of the support pins.
In the present utility model, the angle adjusting part 2 shown in fig. 1 has a cubic structure, and in practical cases, the angle adjusting part 2 may have any structural shape, and the angle limiting hole 5 may be provided.
The length of the anchorage nail can be selected according to the actual treatment requirement, but the conditions of too shallow implantation depth and poor stability of the anchorage nail can also exist. The angle adjusting part 2 of the hollow structure is arranged, so that when the initial stability of the implantation of the anchorage nail is poor, the angle adjusting part 2 of the hollow structure can be compressed, the implantation depth of the anchorage nail can be increased continuously, and the initial implantation stability of the anchorage nail can be increased. That is, the present application can achieve not only operational freedom in the depth of clinical implantation, but also good stability. Preferably, the material thickness of the angle adjusting part 2 is less than or equal to the thickness of the supporting pin positioning die plate 1 so as to reduce the resistance of the compression angle adjusting part 2. The material of the angle adjusting part 2 and the material of the supporting pin positioning template 1 can be the same, and vice versa.
According to the utility model, the anchorage nails can be accurately implanted based on the angle limiting holes and the positioning holes, and in order to obtain initial implantation stability, the anchorage nails can be implanted in a deeper part by utilizing the hollow angle adjusting part, and the guide plate is separated left and right after good stability is obtained. Compared with the prior art, the utility model not only can improve the accuracy of the implantation of the anchorage nail, but also can freely adjust the implantation depth according to the clinical actual situation, and obtain good stability, thereby improving the good healing effect after implantation and having simple subsequent disassembly mode.
In this specification, the embodiments are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same similar parts between the embodiments are all enough to refer to each other.
The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of which is intended only to assist in understanding the methods of the present utility model and the core ideas thereof; also, it is within the scope of the present utility model to be modified by those of ordinary skill in the art in light of the present teachings. In view of the foregoing, this description should not be construed as limiting the utility model.
