Description

Bone plate

This creation is about a bone plate, especially a bone plate that is used in artificial dental implant surgery, which makes the surgical procedure simple and has good structural support, so as to guide the regeneration of bone tissue.

Today, the development of artificial dental implant technology has reached maturity, and it has gradually become the primary choice for most dentists in the treatment of missing teeth. In general, artificial dental implant treatment is not a simple operation of implant surgery. Since the teeth of the patient are removed, the bones will be reshaped, so that the vacancies on the alveolar bone are filled by soft tissue, which usually causes the bone volume to shrink. Normal teeth may also cause lesions around the teeth due to factors such as periodontal disease, which may damage the alveolar bone, causing the bone defect to collapse when the physician pulls the teeth. All of the above reasons can cause the lack of bone quality in the missing teeth, which affects the stability of the implant, and even causes the implant surgery to be impossible.

In cases of severe bone defect, the physician may choose to perform bone surgery to increase the bone quality of the patient's missing teeth. After the bone tissue is regenerated to the desired width and height, the implant surgery is performed to ensure the lack of bone surgery. The alveolar bone implant (ie artificial root) implanted in the tooth has sufficient bonding strength with the alveolar bone. Referring to Fig. 1, a conventional bone plate 9 is composed of a porous structure. The bone plate 9 can be used by a physician for bone surgery to cover the alveolar bone of the patient's bone defect to provide proper growth space for the bone tissue, and to prevent the patient from squeezing the affected part again when chewing, thereby hindering the tooth. The growth of the trough.

The bone plate 9 is capable of combining the ossification surgery and the implant surgery into the same stage of the surgical procedure. In detail, the bone plate 9 has a fixing hole 91 and an extending portion 92, wherein the extension Portion 92 is composed of a porous structure. When the physician uses the conventional bone plate 9 for artificial implanting, the one alveolar bone implant can be directly implanted into the alveolar bone, and a fixed platform is locked in the alveolar bone implant, and the bone plate 9 can pass through the fixing. The hole 91 is positioned to pass through the fixed platform, and is then locked with the fixing platform by a fixing cap to clamp and fix the bone plate 9. With the above structure, the extension portion 92 of the bone plate 9 can be bent to well cover the alveolar bone at the defect site of the patient.

However, the extension 92 of the conventional bone plate 9 is composed of a porous structure that makes it easy to bend and provides a space for soft tissue exposure. However, although the porous structure allows the extension portion 92 to have good plasticity, it also causes the physician to not easily locate the desired portion during the operation, and it is difficult to accurately fold the ideal fold line, resulting in high difficulty in operation.

Furthermore, the physician must perform the cutting action on the extension portion 92 according to the shape of the clinical alveolar bone defect, so as to prevent the area of the extension portion 92 from being too large and excessively protruding into the patient's gums, and at the same time ensuring that the extension portion 92 can be completed. Cover the socket of the missing tooth. However, the artificial cutting process will lead to an increase in the complexity of the operation, which may easily cause errors in the operation of the operation, affect the accuracy of the implant operation, and the bone plate 9 will also produce rough edges or sharp edges after being cut, and the patient may be scratched. Risk.

Further, since the extending portion 92 is composed of a porous structure, the above-described bending and cutting operations are difficult to perform, and if the extending portion 92 is inadvertently formed into a wrong bending, even if the extending portion 92 is pressed back to the plane by the forceps The structural strength of the bone plate 9 is still reduced, and the physician is bound to switch to the new bone plate 9; or, if the physician mistakenly mistakes the extension portion 92, the bone plate 9 is scrapped as well. Switching to a new bone plate 9 will greatly increase the cost of surgery in both cases.

In summary, when using the conventional bone plate 9 for artificial implanting, it has many shortcomings such as "high surgical difficulty", "potential surgical risk" and "high surgical cost", and further improvement is needed to improve artificial dental implants. Treatment quality.

The purpose of the present invention is to provide a bone plate. By providing a guide groove, the guide groove is easily bent to form an ideal fold line on the bone plate, which has the effect of reducing the difficulty of surgery.

Another object of the present invention is to provide a bone plate which is provided for the user to cut, so that the trimmed edge has a lower roughness and sharpness, and has the effect of reducing the risk of surgery.

A further object of the present invention is to provide a bone plate through which the guide plate is provided as a basis for bending or cutting the bone plate to prevent erroneous bending or cutting errors, thereby reducing the cost of surgery. The effect.

The bone plate 5 also has a fixing hole 51 , an abutting portion 52 , at least one extending portion 53 , and a wing piece 55 . And a tongue piece 56, which is different from the foregoing fourth embodiment in that a plurality of fifth guide grooves 545 are provided at intervals between the abutting portion 52 and the tongue piece 56. Therefore, if the teeth of the patient are arranged too tightly, the user can reduce the area of the extending portion 53 by bending the fifth guiding groove 545 closer to the fixing hole 51, so that the tongue piece 56 is opposite to the same. When the joint portion 53 is bent toward the abutment surface B1 of the alveolar bone B, it does not cause frictional contact with the adjacent teeth; When the defect of the abutment surface B1 of the alveolar bone B of the patient's tooth is serious, the user can bend the fifth guide groove 545 farther away from the fixing hole 51 to the abutment portion 52 and the tongue piece 56. A sufficient space is formed between the alveolar bone B to proliferate. Accordingly, the utility of the bone plate 5 of the fifth embodiment of the present invention can be effectively increased by the arrangement of the plurality of fifth guiding grooves 545, and the plurality of fifth guiding grooves 545 can also be used for cutting, so that the tongue The area of the piece 56 can be adjusted to meet clinical needs and will not be further described.

Please refer to FIG. 9 again, which is a bone plate 6 of the sixth embodiment. The bone plate 6 also has a fixing hole 61, an abutting portion 62, at least one extending portion 63, a wing piece 65 and a tongue. The sheet 66 differs from the foregoing fourth embodiment in that the length of the extension 63 is less than the length of the flap 65. Thereby, the flap 65 will protrude from the end edge of the extending portion 63 to form a convex portion 651 capable of the alveolar bone from the bottom side of the alveolar bone B during the operation. The buccal side B2 or the lingual side B3 of B forms a good coating. However, the structure of the bone plate 6 can also be formed by cutting the bone plate of the foregoing embodiment, and directly manufacturing the bone plate 6 only further simplifies the surgical procedure.

In summary, the bone plate of the present invention is provided with a guiding groove, and the characteristic that the guiding groove is easily bent can make the user fold the ideal folding line accurately on the bone plate during the operation. Accordingly, the bone plate of the creation does have the effect of reducing the difficulty of surgery.

Furthermore, the bone plate of the present invention can be used for cutting by using the guide groove provided by the user, and the area and shape of the bone plate can be adjusted, and the bone plate is directly cut along the guide. After the groove is cut, the cut edge of the bone plate 1 has low roughness and sharpness, and is not easy to scratch the patient's gums, and has the effect of reducing the risk of surgery.

In addition, the bone plate of the present invention can be used as a basis for bending or cutting the bone plate through the arrangement of the guide groove, and the bone plate 9 is purely dependent on the user to perform the bending or cutting action by visual estimation. The use of the bone plate of the present invention can prevent erroneous bending or cutting errors, thereby increasing the success rate of the surgery, and indeed has the effect of reducing the cost of surgery.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and it is still within the spirit and scope of the present invention to make various changes and modifications to the above embodiments. The technical scope of protection, therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application attached.
