Expansion-fixed combined implant
Technical Field
The application relates to the technical field of tooth implantation.
Background
At present, the dental implant is installed in an oral cavity in a threaded connection mode, a complex drilling operation is firstly performed on the alveolar bone of a patient, and then the dental implant and the alveolar bone are fixed together through screws. The operation can damage alveolar bones and mucoperiosteum flaps, and the problems of bleeding in the operation, swelling after the operation and the like are very easy to occur, and the operation can be healed after a long time. In order to improve the initial stability of the dental implant, some dental implants are designed with an expansion structure, and based on the original threaded connection mode, the initial stability of the dental implant is further improved by adopting a structure similar to an expansion screw. However, these implants with an expanded structure require prior perforation of the alveolar bone of the patient. In the early days, there was also a planting method of knocking an implant into a dental socket, which does not require drilling in advance, but also causes great damage to the alveolar bone and even the entire jaw bone.
The Chinese patent application publication No. CN 101690679A discloses an expansion type dental implant, which comprises an implant body, an expansion core matched with the implant body and a restoration base station, wherein the expansion core and the restoration base station are mutually in threaded embedding. According to the technical scheme disclosed by the patent, the tightness of the implant in the bone can be improved, so that the initial stability is improved, the loosening and falling rate is reduced, but the loosening of the implant is easily caused in the screwing-in process of the expansion core and the repairing base, and the implant has more internal gaps, so that bacteria and foreign matters are easily invaded in the initial stage of the implant, and the growth combination of the implant and the alveolar bone is influenced.
Disclosure of Invention
The application provides an expansion-fixed combined implant, which adopts an expansion-deformation mounting and fixing mode, can be directly placed into a tooth socket without punching on an alveolar bone in advance, and realizes mounting and fixing in a mode of increasing interference through expansion, thereby reducing damage, improving initial stability of the implant and greatly shortening recovery period of a patient.
