Background
In order to avoid damaging the treatment layer on the surface of the dental implant during packaging and transportation before use, the dental implant is usually fixed with the packaging by using a carrying device when leaving the factory.
The implantation tool is used for connecting the carrying device and the manual torque wrench (or the dental handpiece), and conveying the dental implant connected with the carrying device to an implantation position for implantation operation. In this case, if there is a mismatch between the implantation tool and the carrier, or the carrier and the implant, it may come off the implantation tool or the carrier before reaching the implantation cavity, and the release material may cause serious harm to the health of the patient if swallowed or inhaled. In addition, too close a fit between the implantation tool and the carrier or between the carrier and the dental implant is not possible, otherwise the difficulty of taking out the implantation tool or the carrier after implantation of the dental implant is increased, and even the dental implant may be taken out together, resulting in implant failure. Therefore, both the carrying device and the implantation tool are important in the dental implantation process.
The existing implant carrying device is mainly composed of two or more parts such as a carrying body, a carrying body screw and the like, and the carrying device is required to be unloaded by disassembling the parts after the implantation operation is finished, so that the operation time is increased and the convenience is reduced; in addition, the greatest problem in clinic of the integrated implant carrier body, which is different from the above-mentioned multiple parts, is that the implant body is easy to fall off from the carrier body before being implanted into the alveolar bone, and in order to prevent the situation that the dental implant body falls off due to the fact that metal deformation cannot be blocked or the situation that an insertion tool is difficult to take out due to the fact that the metal deformation cannot be blocked, a material with good elasticity must be selected; the insertion tool needs to be matched with a dental handpiece, a torque wrench and the like for implantation operation in the later period, and the required torsion resistance is high, so that a material with high hardness is required; the material needs to have both good elasticity and high hardness, which increases the material cost.
