Description

Multi-piece Artificial Dental Implant Structure

technical field

The invention relates to an artificial dental implant structure, in particular to a multi-piece artificial dental implant structure.

Background technique

Dental health is very important, but nowadays people neglect regular maintenance because they are busy, and also because they neglect to clean their teeth every day, causing periodontal disease and tooth decay. When the condition of tooth decay is serious, it is necessary to extract the tooth and install dentures. Dentures can be divided into fixed dentures and removable dentures. Fixed dentures directly adhere the dentures to the root of the tooth. This method must be established when the root of the tooth is still quite healthy. ; or fix the dentures with the front and rear teeth by casting a set of movable dentures, but the use of movable dentures tends to make the adjacent teeth tilt and accumulate debris, causing bacteria to grow. The movable dentures set by the above method are all supported by the mucous membrane of the gums, and when chewing food, the force cannot be transmitted to the jawbone, so the dentures cannot be used to chew hard food, which is its main disadvantage.

With the development of "artificial implant" technology becoming more and more mature and stable, the artificial tooth root of artificial tooth with high biocompatibility of titanium is placed in the alveolar for fixation and sutured, and after several months, the artificial tooth root and After the bones in the alveolar are firmly connected, the subsequent installation of dentures will be performed. Since the artificial tooth root is directly connected to the bone, it can provide better support and is popular for chewing hard food. And the implant shape of artificial tooth can be divided into single-piece or multi-piece dental implant, single-piece dental implant such as the "Dental Implant" of U.S. Patent Publication No. 2010/0119993, the single-piece dental implant The structure is directly placed into the bone groove and fixed. After a few months, when the one-piece dental implant and the bone groove are osseointegrated and fixed, the mold is then made and the denture sleeve is directly fixed on the one-piece dental implant. superior. The advantage of the above method is that there are less restrictions on the depth of the implant during implantation, and the implant is relatively strong and not easy to break. The dental implant protrudes out of the soft tissue. During the period of waiting for osseointegration, the one-piece dental implant is likely to be disturbed by the occlusal interference of the implant operator when chewing, resulting in insufficient osseointegration strength and affecting the dental implant. In addition, the one-piece dental implant can no longer cooperate with other kits, and there is less room for denture design.

The multi-piece dental implant is such as the "Dental Implant" of US Patent Publication No. 2008/0160483. The multi-piece dental implant divides the dental implant into an implant (enossal implant) and a coronal portion (coronal portion), When implanting a tooth, the implant is first implanted in the bone trough so that the implant does not protrude from the cortical bone layer in the bone trough, and the cortical bone layer is covered with a layer of soft tissue (soft tissue) layer , the oral cavity is located on the soft tissue layer, so the implant will not be disturbed by occlusion after implantation. After the implant and the bone socket are osseointegrated and fixed, the soft tissue layer is surgically incised and the coronal part is locked and fixed on the implant, and finally a mold is made to fix the denture on the protruding soft tissue. layer outside the coronal part. The advantage of this method is that it can effectively avoid the problem of occlusal interference. On the other hand, the coronal part can be designed in a variety of ways, and can be fixed in combination with different denture designs. But its disadvantage is that the implant must be precisely locked and cut flat on the superficial bone layer to facilitate subsequent coronal engagement. For example, if the implant is too locked into the epidermal bone layer, the implant may be slightly covered by the epidermal bone layer during osseointegration, making subsequent engagement of the coronal portion difficult. Another disadvantage is that the structural strength is relatively poor. Since the coronal part is mostly fixed on the implant by screw locking, and the coronal part is arranged in the soft tissue layer, the supporting force in the horizontal direction of the coronal part is relatively insufficient , so when the coronal portion is subjected to horizontal shear force, the screw lock structure is likely to break. Once the screw lock structure breaks, the remaining screw lock parts are still locked in the implant, and it is not easy to take it out, so the repair is quite difficult. difficulty.

Contents of the invention

The main purpose of the present invention is to solve the problems that single-piece dental implants are prone to occlusal interference during dental implantation, and the overall structural strength of multi-piece dental implants is poor, resulting in fracture and difficult repair.

To achieve the above purpose, the present invention provides a multi-piece artificial dental implant structure, which includes an implant body, a platform body and a dental kit. The dental implant has an implant part, an abutment part, an auxiliary fixing part arranged between the implant part and the abutment part, the implant part is fixed on a bone layer and a The epidermal bone layer on the surface of the layer, and the auxiliary fixing part is fixed on a soft tissue layer on the side of the epidermal bone layer away from the bone layer. The abutment body has a connecting portion connected with the top connecting portion and a positioning portion. The tooth set has an accommodating space for accommodating the abutment body and an auxiliary support part matched with the auxiliary fixing part.

Further, the outer surface of the implant part has a threaded section.

Further, the connecting part has a through hole, and the abutting part has a screw lock groove extending toward the auxiliary fixing part, and a screw lock component is locked and fixed in the screw lock groove through the through hole, thereby fixing the dental implant body and the support body.

As can be seen from the above description, compared with the prior art, the present invention is characterized in that: the dental kit is used to completely cover the abutment body, and the auxiliary fixing part protruding from the epidermal bone layer cooperates with the dental kit. The auxiliary supporting part strengthens the supporting force in the horizontal direction of the abutment body, and reduces the probability of the abutment body being broken by the horizontal shear force.
