[0041] see Figure 8, which is the fourth embodiment of the self-expanding two-stage implant of the present invention. The difference between it and the first embodiment is that the outside of the implant 1 is shaped like a tooth root, and the incision groove 12 is located in the middle of the implant 1. When the imitation root-shaped implant 1 is used for immediate implant surgery, the matching implant 1 is directly placed in the tooth extraction socket; then, the expansion screw 4 is screwed in to a predetermined depth inside the implant 1 Finally, the incision groove 12 in the middle of the implant 1 is expanded outwards, and then screwed into a sanitary cap and the wound is conventionally sutured. During the second-stage operation, the sanitary cap is removed, and the abutment 2 is connected to the implant 1 with the connecting screw 3 to complete the restoration of the denture.

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...
