The implant substitute 210 is mainly used in the plaster model, and mainly functions to accurately transfer the implant information in the oral cavity of the patient to the plaster model, so that the medical staff can conveniently design the upper structures such as the implant abutment 220 on the substitute. The implant abutment 220 can be a healing abutment, the healing abutment can shape the gum and form a gum cuff after the implant implantation operation, a plaster model is manufactured after data such as tooth form and spatial position arrangement in the mouth of a patient are acquired by adopting a traditional impression mode after the shaping, then a three-dimensional data model of the tooth form and arrangement in the mouth of the patient is acquired by installing a scanning rod to scan the plaster model, and then a permanent abutment and a dental crown are designed and manufactured through CAD/CAM.
In this embodiment, the implant substitute 210 and the implant base 220 can be made of titanium alloy, so that the implant substitute has good hardness and strength and long service life. Specifically, the insertion hole 211 is a blind hole formed in the implant substitute 210, and may have a circular hole shape, and the connection hole 221 is a through hole formed in the implant base 220, and has a circular hole shape identical to the insertion hole 211. In practical application, after the planting base 220 is inserted into the insertion hole 211, the planting base 220 and the substitute implant 210 can be further fastened and connected by a connector, so as to ensure stable and reliable connection between the planting base 220 and the substitute implant 210.
In an embodiment of the present application, the separating rod 100 is made of steel, for example, carbon steel or carbon steel, and the steel material has good structural strength, is not easy to deform, and has good wear resistance, so that the steel separating rod 100 can ensure a long service life.
Therefore, the utility model discloses technical scheme's separation tool, at the in-process of separation planting substituent 210 and planting base station 220, insert jack hole 211 with separation rod 100 from connecting hole 221 earlier, make second screw thread 121 of cooperation section 120 can begin to cooperate with first screw thread 2211 on the connecting hole 221 pore wall, then continue the intensive in-process of cooperation, when the diapire of jack hole 211 is contradicted to tight section 110, this moment because cooperation section 120 carries out the screw precession with connecting hole 221, and the precession is supported tight section 110 and is kept out, consequently, through the relation of effort with reaction force, make screw-thread fit's planting base station 220 compelled move outwards with it, thereby make planting substituent 210 and planting platform separate. The design of this structure only needs application of force in cooperation section 120, separates through the reaction force of screw precession for labour saving and time saving more in the disengaging process, thereby can make things convenient for, quick separation planting substitute 210 and planting base station 220.
In an embodiment of the present application, an end surface of the fastening section 110 far from the end of the fitting section 120 is a plane. That is, the fastening section 110 is formed as a cylindrical section, and the bottom wall surface of the insertion hole 211 is also formed as a plane, so that when the fastening section 110 is abutted to the bottom wall of the insertion hole 211, the fastening section 110 is in plane contact with the bottom wall of the insertion hole 211, so that in the process of screwing the first thread 2211 and the second thread 121, the stressed surface between the fastening section 110 and the bottom wall of the insertion hole 211 is large, the friction damage is not easy to occur, and the service life of the separation tool can be prolonged.
In another embodiment of the present application, an end surface of the fastening section 110, which is far away from the end of the mating section 120, is a conical surface. In this embodiment, the end of the tightening section 110 away from the fitting section 120 is formed as a tapered end, so that when the tightening section abuts against the bottom wall of the insertion hole 211, the tightening section can be screwed into the bottom wall of the insertion hole 211 to gather stress, and therefore, the tightening section can quickly push the planting base 220 out of the insertion hole 211 through the reaction force, so that the operation is more labor-saving.
Further, in an embodiment of the present application, an end surface of the fastening section 110, which is far away from the end surface of the fitting section 120, is provided with a wear-resistant layer (not shown). The wear-resistant layer can be a surface treatment layer, such as a chromium plating layer, a tungsten carbide treatment layer, a laser treatment layer or a coating layer of a high-molecular ceramic polymer. As can be appreciated, by providing the wear-resistant layer, the wear resistance of the clinching segment 110 can be further increased, so that wear is less likely to occur.
In an embodiment of the present application, the outer diameter of the fastening section 110 is smaller than the outer diameter of the mating section 120. Due to the arrangement, the abutting section 110 cannot interfere with the first thread 2211 on the inner wall of the connecting hole 221 in the process of passing through the connecting hole 221, so that the abutting section 110 can be smoothly abutted to the bottom wall of the inserting hole 211.
Of course, in other embodiments, the outer diameter of the fastening section 110 may be the same as the outer diameter of the mating section 120, and the outer sidewall of the fastening section 110 is also provided with the second thread 121, so that the separation rod 100 is screwed into the first thread 2211 after being inserted into the connection hole 221, and is forced to push back when being screwed to the bottom wall of the insertion hole 211.
In this application, the separation rod 100 still includes linkage segment 130 and closes section 140 soon, linkage segment 130 connect in cooperation section 120 is kept away from support tight section 110's one end, close section 140 soon connect in linkage segment 130 is kept away from the one end of cooperation section 120, close section 140 soon and be equipped with and be used for supplying first screw thread 2211 with second screw thread 121 matched with structure 141 of screwing. In this embodiment, by the arrangement of the connection section 130 and the screwing section 140, after the force is applied to the screwing section 140 conveniently, the matching section 120 is screwed in the inner wall of the connection hole 221 in a threaded matching manner, and the operation is more labor-saving in the separation process through the design of the screwing structure 141.
In one embodiment, the screwing structure 141 is a hexagon socket structure recessed in the screwing section 140. In this embodiment, a standard socket wrench can be used to act on the socket structure, and the screwing section 140 can be screwed into the connection hole 221 from outside the planting base 220, so as to ensure that the planting base 220 can be pushed out of the insertion hole 211 in a reverse manner, and the operation is labor-saving.
In another embodiment, the screwing structure 141 is an external hexagonal structure disposed on the screwing section 140. In this embodiment, the screwing section 140 extends out of the planting base 220 through the connecting section 130, and during the separation process, an external hexagonal wrench can be used to act on the external hexagonal structure and screw in close to the planting base 220, thereby increasing the selectivity of the auxiliary tool.
Further, in the embodiment of the present application, the fastening section 110, the mating section 120, the connecting section 130, and the screwing section 140 are an integral structure. Therefore, the structural strength between the segments of the separating rod 100 is good, the separating rod is convenient to machine, form and manufacture, and the machining efficiency of the separating tool can be greatly improved.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
