Description
Technical Field
The invention relates to the technical field of dental tools, in particular to a dental implant carrying device and an implantation tool assembly matched with the same.
Background
The surface of the dental implant is specially treated, in order to prevent the surface of the dental implant from being damaged when being packaged and moved, and meanwhile, a doctor can take out the dental implant from the package and put the dental implant into the planting cavity for implantation conveniently, and a dental implant manufacturer generally can manufacture a carrying device to fix the dental implant and the package.
The implantation tool is used for connecting the carrying device and a manual torque wrench (or a dental handpiece) and transferring the dental implant connected with the carrying device to an implantation part for implantation operation. In this case, if a mismatch between the implantation tool and the carrier, or the carrier and the implant, occurs, it may fall off the implantation tool or the carrier before reaching the implantation pocket, and the detached object, if swallowed or inhaled, may pose a serious health hazard to the patient. Furthermore, the implant tool and the carrier or the carrier and the dental implant do not fit too tightly, which would increase the difficulty of removing the implant tool or carrier after implantation, or even remove the dental implant together, resulting in implant failure. Therefore, both the carrier and the implantation tool are important in the dental implantation process.
The existing carrying device is mainly composed of two or more parts such as a carrying body and a carrying body screw. Because the size of the part is small, the part needs to be processed by precise equipment, and the manufacturing cost is high. Meanwhile, it is necessary to unload the carrier by disassembling these components after the implantation operation is completed, resulting in an increase in operation time and a reduction in convenience.
The carrier of some manufacturers is integrated, the insertion tool (equivalent to the carrier in the industry) has a complex shape, special processing equipment such as a processing center is needed for processing, and the processing cost is high. The part of the insertion tool used for clamping the dental implant is made of metal, and a material with good elasticity is required to be selected in order to prevent the situation that the dental implant falls off due to the fact that the metal is deformed and cannot be clamped or the situation that the insertion tool is difficult to take out due to the fact that the metal is clamped too tightly; in addition, the insertion tool needs to be matched with a dental handpiece or a torque wrench and the like for implantation operation at the later stage, so that the required torsion resistance is higher, and a material with higher hardness is required; in other words, the material needs to have both high elasticity and high hardness (such as titanium alloy, etc.), which increases the material cost.

The diameter of the joint 121 is larger than that of the connecting rod 122, and the diameter of the joint 121 is slightly larger than the threaded inner hole of the dental implant. The joint 121 is further provided with a slot shaped like a straight line so as to be contracted when the dental implant is inserted. The chamfered edge at the end of the tab 121 also helps to facilitate insertion into the dental implant.
The carrying body 110 is a medical stainless steel member, and the connecting body 120 is a polyetheretherketone member. The link 120 is obtained by integrally molding by adding a mold to the carrier body 110 and directly injection-molding the link mounting hole and the mold.
Example 2, a dental implant carrier, as shown in fig. 2 and 3, comprising:
as shown in FIG. 3, the carrier 210 is a cylindrical member having an implantation tool coupling section 211 at one end and a dental implant coupling section 212 at the other end. The implantation tool coupling section 211 is adapted to an external implantation tool interface; the dental implant bonding section 212 is adapted to an abutment interface of an external dental implant.
