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.
