Background

The dental implant is structurally divided into three parts, namely an abutment, an implant and a central screw, in the process of implanting the dental implant, a dentist firstly implants the dental implant into an alveolar bone of an edentulous part in a surgical operation mode, after the implant and the alveolar bone are healed, the implant is connected with a conversion abutment, and a ceramic crown is fastened and fixed on the conversion abutment to complete the process of implanting the false tooth. The German Branemark made a first titanium nail implant in the mouth of a rabbit in 1965 by using pure titanium metal, and later made a functional test on dogs for 10 years, and all the results obtained in vivo experiments. Compared with the traditional fixed bridge and movable false tooth restoration, the dental implant has the advantages of beauty, comfort, reliability and the like, becomes the third pair of teeth of a patient with a defective dentition and is widely concerned.

In the process of artificial tooth implantation, the implant needs about three months for healing after being implanted in the alveolar bone, an internal thread hole for abutment connection is formed in the implant, and the lower end part of the abutment is in threaded connection with the internal thread hole; before the abutment is installed, the internal threaded hole is blocked, so that the internal threaded hole is prevented from entering food residues and other substances in the cavity in the healing time period of the implant, and meanwhile, in the healing period of the implant and the alveolar bone, the internal threaded hole is prevented from being blocked by continuously healed gingiva, so that the healing abutment needs to be screwed up in the internal threaded hole of the implant in the healing period; in the forming process of porcelain tooth, need make the data acquisition of porcelain tooth according to the inside structure in patient's oral cavity to carry out the sintered forming of porcelain tooth in the later stage, at the collection in-process of the inside data in oral cavity, the healing base station be provided with the collection of the inside space data in oral cavity of being convenient for, and then the setting of healing base station plays the effect of the intraoral data acquisition of being convenient for again, and the healing base station forms the scanning healing base station gradually.

With respect to the related art in the above, the inventors consider that there are the following drawbacks: the existing scanning healing abutment comprises a scanning rod and a central screw, the lower end part of the scanning rod is in inserted fit with an internal thread hole on an implant, and the central screw penetrates through the scanning rod and is in threaded connection with the internal thread hole; in the healing period of a patient of nearly three months, along with the process that the patient chews continuously, food inside the oral cavity accompanied by the central screw is continuously collided, so that the central screw and the scanning rod are easy to rotate relatively, and the central screw is easy to loosen; the loose central screw reduces the integrity between the scanning rod and the implant, so that bacteria and other substances in the oral cavity are easy to enter the inner part of the inner threaded hole from the inlet positions of the scanning rod and the inner threaded hole, the cleaning and sterilizing operation during the installation of the abutment is increased, the discomfort of a patient in the false tooth implanting process is increased, and the improvement space exists.

When each group of the limiting blocks 13 is inserted into the sliding groove 21, each group of the limiting blocks 13 is abutted with the sealing gasket 23 and continuously presses the sealing gasket 23, when the sealing gasket 23 is pressed, each group of the limiting blocks 13 enters the position of the first wall groove 221, at the moment, the cap part 2 is further rotated, each group of the limiting blocks 13 approaches to the position of the second wall groove 222, when each group of the limiting blocks 13 is positioned at the position of the second wall groove 222, the grasping of the cap part 2 is released, and under the action of the sealing gasket 23, each group of the limiting blocks 13 receives the thrust of the sealing gasket 23, each group of the limiting blocks 13 is inserted into the second wall groove 222, so that the fixed connection between the cap part 2 and the scanning rod 1 is completed.

When the patient passes the healing period, the internal data of the oral cavity of the patient needs to be scanned by means of the scanning healing base station, and the internal data of the oral cavity is scanned by means of the oral scanner. After the mouth-sweeping is completed, the dentist holds the cap 2, the position of the groove 25 is taken as a reference, the sealing gasket 23 is compressed and contracted when the cap 2 is pressed, the cap 2 is reversely rotated at the moment, so that the groups of limiting blocks 13 and the cap 2 relatively rotate, the groups of limiting blocks 13 sequentially rotate to the first wall groove 221 and the sliding groove 21, and under the thrust action of the sealing gasket 23, the groups of limiting blocks 13 continuously separate along the sliding groove 21, so that the cap 2 is separated from the end part of the scanning rod 1. And finally, taking down the central screw 4 by means of a wrench, taking down the scanning rod 1 from the implant 3, further sterilizing the implant 3 and the cuff formed by the gum, replacing the sealing gasket 23, refilling medical alcohol, and installing the next conversion base station. In the application, the cap part 2 is buckled on a stepped shaft 12 at one end of the scanning rod 1, the limiting blocks 13 at the end part of the scanning rod 1 are inserted into the sliding grooves 21 in the cap part 2, the cap part 2 is made of medical rubber, the cap part 2 has good elasticity, the cap part 2 blocks the end part of the scanning rod 1, so that the central screw 4 at the end part of the scanning rod 1 is covered, and the cap part 2 is arranged to prevent food from directly contacting with the central screw 4; the sealing ring 312 inside the hole 31 plays a role in sealing gaps between the scanning rod 1 and the implant 3, improves the sealing performance of the scanning healing abutment and the implant 3 in a healing period in the cooperation, reduces the generation of bacteria inside the oral cavity inside the internal thread hole 32 on the implant 3, and reduces the cleaning and sterilizing operation in the denture planting process.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
