Description

Bone plate

This creation is about a bone plate, especially a bone plate with simple surgical procedures and good structural support to facilitate 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. When the tooth is implanted in the alveolar bone implant (ie artificial root), it has sufficient bonding strength with the alveolar bone. Referring to Fig. 1, a conventional bone plate 8 sold by ACE surgical supply, Inc. is composed of a porous structure. The bone plate 8 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.

However, the conventional bone plate 8 has a number of disadvantages. For example, the physician must perform the cutting action on the bone plate 8 according to the shape of the clinical alveolar bone defect, but the artificial cutting will result in a hand. Increased complexity, easy to cause errors in surgical procedures, affect the accuracy of implant surgery, and the cut bone plate 8 also has the risk of scratching the gums of the patient; in addition, the bone plate 8 must be fixed via the nail In the alveolar, it is considered that the insertion of the nail may cause secondary damage to the alveolar bone. The patient with severe bone defect is not suitable for the bone plate 8; in addition, the physician must use the conventional bone plate 8 for bone surgery. After the end of the skeletal surgery, the bone plate 8 can be removed, and the dental implant surgery can be continued. When the bone plate 8 is removed, the wound is easily caused, resulting in the extension of the dental implant surgery, the cost of medical treatment, and the increase of patients and physicians. Troubled.

In order to solve the above problem, please refer to Fig. 2, which is another conventional bone plate 9 sold by NeoBiotech, Korea, which can combine 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, an extending portion 92 and a plurality of fins 93. The extending portion 92 is also 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 on 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 and the flap 93 of the bone plate 9 can be bent to cover the alveolar bone of the patient's bone defect portion, so that the bone plate 9 usually does not need to be additionally cut, and the surgical complexity can be reduced. And avoiding the risk of scratching the gums of the patient; in addition, the bone plate 9 is clamped and fixed to the alveolar bone implant through the fixing hole 91, and no additional nails are required to be inserted, thereby effectively avoiding the formation of the alveolar bone. In addition, the surgeon can use the bone plate 9 to perform the surgical procedure of the skeletal surgery and the implant surgery at the same time. Compared with the use of the conventional bone plate 8, the bone surgery must be completed before the implantation of the alveolar bone implant can be started. The bone plate 9 can greatly improve the efficiency of surgery.

The extension 92 of the conventional bone plate 9 is composed of a porous structure that is easily bent 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. And if the inadvertent portion is formed, the extension portion 92 is formed. In the case of erroneous bending, even if the extension portion 92 is pressed back into a flat shape by the forceps, the structural strength is still lowered, and the physician is bound to switch to the new bone plate 9, which greatly increases the surgical cost.

In summary, the use of the conventional bone plate 9 for artificial dental implants has the disadvantages of "higher surgical difficulty" and "high surgical cost", and further improvement is needed to improve the quality of artificial dental implant treatment.

The purpose of the present invention is to provide a bone plate which is provided with a non-porous portion which can be prevented from being bent, thereby preventing erroneous bending from occurring, and having the effect of reducing the cost of surgery.

The metal component can provide a high supporting force and avoid the collapse of the bone plate 1 when it is forced. The bone plate 1 is a piece of a body, and has a fixing hole 11 . The fixing hole 11 can be a circular hole, an elliptical hole, a polygonal hole or an irregular hole. The present invention is not limited thereto. A non-porous portion 12 is formed around the fixing hole 11, and the non-hole portion 12 is a continuously extending surface, and no additional holes are formed. In detail, a hole is not formed in a range of a distance D from the circumference of the fixing hole 11, and the non-hole portion 12 is formed. The distance D may be the distance between the circumference of the fixing hole 11 and the gingival flap. Accordingly, the distance D can be designed to have different sizes depending on the type of teeth to which the bone plate 1 is applied, and the distance D is preferably less than 5 mm. The non-porous portion 12 is further connected to an extending portion 13 having a plurality of through holes 131 formed therein.

Referring to Figures 4 and 5 together, when the bone plate 1 of the first embodiment is actually used, the physician can first implant an alveolar bone implant I into the alveolar bone B, followed by the alveolar bone. A fixed platform S is locked in the bone implant I, and the bone plate 1 is positioned on the fixed platform S by using the fixing hole 11, and then the fixed platform C is locked with the fixed platform S. The bone plate 1 is clamped and fixed. However, a screw (not shown) can be passed through the fixing hole 11 to directly lock the bone plate 1 to the alveolar bone implant 1. The use of the bone plate is not limited. The non-porous portion 12 of the bone plate 1 is opposite to the abutment surface B1 of the alveolar bone B. Further, in the present embodiment, the two sides of the non-porous portion 12 are respectively connected to the opposite two extension portions 13, The plurality of through holes 131 are formed on the extending portion 13, so that the boundary between the extending portion 13 and the non-porous portion 12 can be bent, so that the two extending portions 13 respectively cover the buccal side of the alveolar bone B B2 and lingual B3, and the perforations 131 of the extension 13 can provide a space for soft tissue exposure of the buccal side B2 or lingual side B3.

Wherein, since the bone plate 1 is opposite to the abutment surface B1 of the alveolar bone B, the non-porous portion 12 is not easily bent, and the doctor can be prevented from inadvertently bending the bone during the operation. A portion of the plate 1 that is opposite to the abutment surface B1. Furthermore, the bone plate 1 can also be provided with a guiding groove 14 at the boundary between the extending portion 13 and the non-hole portion 12.
