Description

100 years li. month ba correction replacement page five, new description: [new technology field] [0001] The present invention relates to an artificial dental implant structure, especially an artificial dental implant structure. [Prior Art] [0002] The health is very important, but now people are neglecting regular maintenance because of their busyness, and also because of the situation of periodontal disease and tooth decay caused by daily neglect of cleaning teeth. When the condition of the cavities is serious, the teeth must be removed and the dentures can be installed. The dentures can be divided into fixed dentures and movable dentures. The fixed dentures directly attach the dentures to the roots. This method must be based on the condition that the roots are still quite healthy. Lower; or the denture is matched with a set of movable dentures for fixing the teeth in the front and rear positions, and the use of the movable dentures tends to cause the adjacent teeth to tilt and accumulate residues to cause bacterial growth. The movable dentures set in the above manner are supported by the mucous membrane of the gums. When crunching food, the force cannot be transmitted to the tibia, and thus it is impossible to use the denture to chew the hard food, which is the main disadvantage. [0003] With the development of the technology of "artificial implants" becoming more mature and stable, the artificial implants are first fixed and sutured in the alveolar by artificial roots of titanium with high biocompatibility, and after several months. After the artificial tooth root and the bone in the alveolar connection are firmly connected, the subsequent operation of the denture is performed. Since the artificial root system is directly connected to the bone, it provides better support and is popular for chewing hard food. The dental implants can be divided into single-piece or multi-piece implants, and single-piece implants such as "Dental Im_" in US Patent Publication No. 201 0/01 19993

Plant", the structure of the single-piece implant is directly placed in the bone groove and fixed. Form No. A0101 Page 3 of 14 M429464 100 years 11. The month h is waiting for a few months after the ¥ page, When the single-piece implant body and the bone groove are osseointegrated and fixed, the mold is then molded and then the denture sleeve is directly fixed on the single-piece implant body. The advantage of the above method is that the implant depth is less restricted when implanted, and the implant body is firm and not easy to break, but the disadvantage is that the single-piece implant body has some single-piece after the bone groove is implanted. The implant body protrudes from the soft tissue (sof tti ssue). During the waiting for osseointegration, the one-piece implant is easily interfered by the bite of the implanted surgeon during chewing, resulting in insufficient strength of osseointegration. In addition to the stability of the implant, the one-piece implant can no longer be matched with other kits, and the denture can be designed with less space. [0004] A multi-piece implant is a "Dental Implant" of US Patent Publication No. 2008/01 60483, and a multi-piece implant body divides the implant body.

For an enossal implant and a coronal portion, the implant is first implanted in the bone groove and the implant is not protruded from the cortical bone in the bone groove. The layer of the epidermis is covered with a layer of soft tissue, which is the oral cavity, so that the implant is not subject to occlusion interference after implantation. After the implant and the bone groove are osseointegrated and fixed, the soft tissue layer is surgically cut and the crown is locked and fixed on the implant tube, and finally the mold is fixed to fix the denture to protrude from the soft tissue layer. On the outer crown. The advantage of this method is that it can effectively avoid the problem of occlusion interference. On the other hand, the coronary system can be designed in various ways, and can be combined and fixed with different denture designs. However, the disadvantage is that the implant must be accurately locked and squashed on the epidermal bone layer to facilitate subsequent engagement of the crown. For example, if the implant is too locked into the epidermal bone layer, the implant may be subjected to the epidermal bone form number A0101 page 4 of 14 M429464 100 years. On the 23rd of the month, the micro-coverage of the top layer of the page was replaced, which caused difficulty in subsequently joining the crown. Another disadvantage is that the structural strength is poor. Since most of the crown is fixed to the implant by means of a screw lock, and the crown is disposed in the soft tissue layer, the horizontal support force of the crown is relatively high. Insufficient, when the crown is pressed by the horizontal shear force, the screw lock structure is easily broken, and the mutual screw lock structure is broken, and the residual screw lock is still locked in the implant tube, so that the removal is not easy. Repairing is quite difficult.

V [New content] [0005] The main purpose of the present invention is to solve the problem that the single-piece implant body is susceptible to bite interference during the tooth implant process, and the overall structural strength of the multi-piece implant body is poor, and the fracture and repair are difficult. problem. [0006] In order to achieve the above object, the present invention provides an artificial dental implant structure, which is a package

Contains a dental implant, a table and a tooth kit. The implant has an implant portion, an abutting portion, and an auxiliary fixing portion disposed between the implant portion and the abutting portion, the implant portion being fixed to a bone layer and a surface of the bone layer The epidermis bone layer, and the auxiliary portion is fixed to a soft group of salt layer located at the bone layer of the epidermis away from the bone layer f. The abutment body has a connecting portion connected to the abutting portion. The dental kit has an accommodating space for accommodating and covering the abutment body and an auxiliary supporting portion for engaging the auxiliary fixing portion. [0007] It can be seen from the above description that the present invention completely covers the abutment body by using the dental kit, and the auxiliary support portion protruding from the outer surface of the epidermis is matched with the auxiliary support portion of the dental kit to strengthen the abutment. The horizontal support force of the body reduces the probability that the abutment body is broken by the horizontal shear force.
