An implant with a flange on the head

Say

Technical field

The present invention relates to the field of dental medicine, and in particular to a head-flanged implant implanted in the alveolar bone by surgery. Background technique

Modern oral implant denture technology based on titanium osseointegration theory has been widely used in clinical practice since its invention in the 1960s. Clinical practice has proved its effectiveness and practicability. In the face of the growing demand for repair treatment, traditional fixed dentures and removable dentures are increasingly difficult to meet people's wishes in many ways. In this case, oral implant medical technology has shown obvious superiority, which fills the tradition. Restoring some of the space left by the limitations of the technology, and the book is constantly evolving, and the implant repairer has almost the same chewing function as natural teeth, and the aesthetics that are as transcendent as natural teeth, have become or Will become the first choice for the treatment of tooth defect repair. Therefore, the extensive development and application of dental implant dentures solves a series of aesthetic and functional problems caused by clinical tooth loss. However, the operation procedure is complicated, the surgical methods are diverse, different types of implant tools are difficult to generalize, surgery and repair. These problems are complicated, and these problems bring a large workload to doctors and dental technicians, and also increase the cost of planting repair and management. An oral implant device (CN201020249801. 9) utility model patent, designed and created a new implant implant device, although it can be applied to a surgical implantation method, that is, a surgical method similar to a perforating implant . However, in this case, unlike the implant with the squat structure, the healing abutment must be placed during the operation, and the joint between the healing abutment and the implant is too close to the jaw bone, which may affect the progress of bone healing. Therefore, the main surgical method is still two surgical implantation methods, that is, implanting the implant for the first time and closing the gums, making the second incision and placing the wound. Abutment. Straumarm's surgical perforating implant is a pioneer in this technology, but it is still a dedicated piercing implant system that is often difficult to implant for surgery, and the world is Many similar surgical methods and surgical tools for implantable implant devices are dedicated, which is complicated and requires investment in hospitals and clinics that require both implanted and piercing implants. Additional cost.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art mentioned above, and to provide an implant with a flange on the head, which has novel structure, easy operation, high stability and good sealing performance, and can be completed only by one operation. Implantation, the device's piercing surgical tool can be fully shared with another implant-implanted surgical tool.

The technical scheme of the utility model is as follows: the implant body of the utility model is provided with a cavity, and a shallow cylindrical pit, an inner conical hole, an inner cylindrical hole and an internally threaded hole are arranged under the end surface, and the inner cylindrical hole is further provided with a convex key The shape of the implant is divided into three parts: the head, the body and the tail. The head is an asymmetrical trapezoidal flange, the body is a micro-tapered cone, and the tail is spherical. 5-3. The height of the asymmetrical trapezoidal flange is 1. 5-3. The angle of the asymmetrical trapezoidal flange is less than 45 degrees, the angle between the lower side and the outer side of the outer circle is less than 45 degrees, the height of the asymmetric trapezoidal flange is 1. 5-3. Between 5 mm. The length of the upper side is smaller than the length of the lower side.

From the theoretical point of view of human body structure, human teeth shape and tissue are similar to bones, and are hard tissues. The bones of the same hard tissue are wrapped in the soft tissue of the human body, but the teeth are different, and it must extend beyond the soft tissue of the human body. Therefore, sometimes the teeth are regarded as the "bone" that protrudes from the human body. Therefore, for artificial implants, there is also a problem of how to "penetrate" the soft tissue of the gums, that is, how to achieve such a piercing structure? If the piercing part is made on the abutment, that is, the abutment structure in the patent CN201020249801. 9, it is a implanted implant, such an implant generally needs to be buried in the bone; and if the piercing part is to be planted Body, like the asymmetric trapezoidal flange in the utility model, so that the flange acts as a "piercing role", that is, a piercing implant, therefore, the piercing implant must have a structure through which the piercing implant is inserted. It is used to achieve the perforation, that is, it will be in the soft tissues of the gums after the operation, and the upper side can be exposed to the human oral cavity, so the implanting operation of the perforating implant does not need to close the gums, nor does the second operation make a gum incision. The piercing flange of the present invention is added to another implant implant (CN201020249801. 9), wherein the upper edge of the flange is also a crown bearing surface.

The beneficial effects of the utility model are as follows: 1. The implant is implanted, and the implant can be completed in only one operation, and the second operation is cancelled, which reduces the patient's pain, the doctor's burden and the surgery cost. 2. Compared with the prior art, an asymmetric trapezoidal flange is added to the implant head, and the flange is a piercing portion, so the surgical tool can be completely versatile with the former, which greatly improves the convenience of use and the application cost can be reduce. 3. It is more convenient to clean, disinfect and manage surgical tools. The workload of tool management is greatly reduced, which can greatly improve work efficiency.
