Two-section implant with spontaneous expansion function

Abstract

The invention discloses a two-section implant with a spontaneous expansion function. The two-section implant is applied to restoration of teeth in dental implanting surgeries. The two-section implant comprises an implant body, an abutment, a connecting screw and an expansion screw, wherein the implant body is connected with the abutment through the connecting screw and is provided with an opening and a notch groove; the expansion screw is screwed into the implant body from the opening, and a wedged slope is utilized for promoting the expansion of the notch groove to generate a tensile force so as to make fastened. The expansion screw with a thread and a taper is screwed into the implant body, and the wedged slope is utilized for promoting the expansion of the notch groove so as to generate the tensile force, so that a fastening effect is achieved, the early-stage stability of the dental implant is improved, and a missing tooth can be restored immediately; and when the appearance of the implant is in the shape of an imitation human tooth root, the damage on bones of patients can be more minimized to a greatest degree on the premise of ensuring the early-stage stability.

Description

technical field [0001] The invention relates to a restoration device in the field of oral implantology, in particular to a two-stage implant with a self-expanding function. Background technique [0002] Due to the reliability and comfort of dental implant restoration compared with traditional fixed bridge and removable denture restoration, people pay more and more attention to its research and use. According to statistics from authoritative organizations, about 10% of people will choose dental implant technology to restore their teeth in their lifetime. In developed countries, nearly 50% of patients with dentition defects and edentulousness will choose dental implant technology for restoration, so dental implants have broad prospects in the field of oral treatment. [0003] However, due to the individual differences in the oral conditions of patients, the existing implant systems have certain limitations. For example, in the case of insufficient alveolar bone mass, osteopo...

AI Technical Summary

Problems solved by technology

The existing implants on the market can only provide cylindrical or conical implants of fixed specifications, and rely on the external thread of the implant to provide the initial stability of the implant. For patients with poor alveolar bone quality, implants after implant restoration The initial stability is insufficient, and more alveolar bone will be lost when applied to immediate implantation, which is not conducive to wound healing
