Description

Dental implant system

Technical Field

The utility model relates to the field of dental implantation technical instruments, in particular to a dental implant system.

Background

With the development of science and technology, the living standard of people is improved, the oral implant technology is rapidly developed and widely applied, the oral implant comprises an intraosseous implant, a connecting abutment and an intraoral artificial tooth, generally, in the process of dental implant surgery, the implant is firstly planted into an alveolar bone, after 4-8 weeks of healing, the implant and the alveolar bone form biological osseointegration, then the abutment is installed in the implant, and finally a porcelain dental false tooth is made on the abutment, in the prior art, a locking device used for connecting the implant and the abutment is a central bolt, for example, Chinese patent CN206761780U discloses a dental implant system which comprises an implant fixed in the alveolar bone, and the implant is provided with a first inner cavity; one end of the abutment is positioned in the first inner cavity, the other end of the abutment is used for connecting the false tooth, and the abutment is provided with a second inner cavity; the central bolt comprises a first end and a second section which are oppositely arranged, the first end is limited in the first inner cavity, and the second end is limited in the second inner cavity; wherein, the first end has first screw portion, the second end has second screw portion, when the planting body, the base station and the central bolt assembly is accomplished, first screw portion with first inner chamber is interlocking, second screw portion with the second inner chamber is interlocking, the shortcoming that above-mentioned patent exists: firstly, after the bolts are embedded into the abutment, slight fit gaps are formed among the abutment, the central bolt and the implant due to manufacturing tolerance, bacteria can easily enter the gaps in the process of chewing food, the bacteria can easily cause inflammation of the implant, and the threaded connection can easily rotate and loosen when the teeth are stressed, so that the abutment sinks, and due to the action of the bacteria, the bolts can easily break, the abutment and the implant are disconnected, and the abutment and the implant need to be installed again; secondly, because the width of the tooth is generally several millimeters, and the false tooth is embedded on the abutment, the width of the abutment is smaller than that of the false tooth, so the abutment is thinner, and a bolt is also required to be installed in the abutment, so the side wall of the abutment is very thin, and people know that the occlusion force of the human tooth is very large, so the hollow abutment is easy to break and needs to be installed again, thereby not only increasing the pain of a patient, but also increasing the treatment cost of the patient; thirdly, because the false tooth has installation angle, when the angle not to the clock, need pass through the direction of instrument adjustment base station, and base station and implant threaded connection, the rotatory back of base station just is inseparable with the combination of implant, and the clearance grow, if the base station irrotational, just need adjust the implant, and the implant combines with alveolar bone biological bone again, and adjustment implant must increase patient's misery, probably still can destroy the implant, need reinstall, very inconvenient.
