Abstract

The invention discloses an expansion fixed combined implant which comprises a bottom column and a top cover. The bottom column comprises a first foundation pile and a second foundation pile, the firstfoundation pile is provided with a first mounting plane, the first mounting plane is provided with a protruded slider, the second foundation pile is provided with a second mounting plane, a sunken slide groove is formed in the second mounting plane, the first foundation pile is slidably connected with the slide groove of the second foundation pile by the slider, the slide groove is provided witha groove bottom wall which is parallel to the second mounting plane, first expansion clearance is reserved between the groove bottom wall and the slider, second expansion clearance is reserved betweenthe first mounting plane and the second mounting plane, and a tenon which can be embedded in the first expansion clearance and the second expansion clearance is arranged on the bottom surface of thetop cover. The expansion fixed combined implant has the advantages that building block type construction and assembly are combined with utilization of mortise and tenon structures, the foundation piles of the expansion fixed combined implant are high in integrity, and accordingly the stability of the expansion fixed combined implant can be guaranteed.

Description

technical field [0001] The invention relates to the field of dental implant technology. Background technique [0002] At present, the installation of dental implants in the oral cavity mostly adopts the method of threaded connection. First, a complicated drilling operation is performed on the patient's alveolar bone, and then the dental implant and the alveolar bone are fixed together by screws. This operation will cause damage to the alveolar bone and mucoperiosteal flap, and problems such as intraoperative bleeding and postoperative swelling are prone to occur, and it takes a long time to heal. In order to improve the initial stability of dental implants, some dental implants have successively adopted an expansion structure design. On the basis of the original thread connection method, a structure similar to an expansion screw is used to further improve the initial stability of dental implants. However, these implants with expansion structure still need to drill the patie...
