Maxillary sinus minimally invasive internal lifting device for dental implants

Abstract

In order to solve such defects in the prior that whether maxillary sinus is successfully lift is hard to judge and the operation is inconvenient, the invention provides a minimally invasive internal maxillary sinus lifting device for implanting teeth. The minimally invasive internal maxillary sinus lifting device comprises a bone fixing element, an internal lifting element and a force applying element, wherein the bone fixing element comprises a cylindrical body, a fixing part is arranged on the outer surface of the cylindrical body, and the cylindrical body is provided with a first through inner hole and a second through inner hole along the axial direction; the internal lifting element comprises a lifting rod and a lifting head, one end of the lifting rod is fixedly connected with the lifting head, the lifting rod is inserted in the first inner hole of the cylindrical main body, the other end of the lifting rod is fixedly connected with the force applying element through threads, and the force applying element is located in the second inner hole of the cylindrical main body. Since the travel of the internal lifting device provided by the invention is controllable, the lifting element is ensured not to break through a mucous membrane of maxillary sinus; in addition, since the integration degree is high, the lifting device provided by the invention is smart in structure and can be conveniently used for carrying out internal lifting operation in oral cavities.

Description

technical field [0001] The invention relates to a medical instrument for stomatology, in particular to a safe minimally invasive internal lifting device for the maxillary sinus used for dental implants when the bone mass of the maxillary sinus floor is insufficient during artificial tooth implantation. Background technique [0002] Dental implant surgery is a procedure in which implants are artificially placed into the alveolar bone to replace lost or lost teeth. [0003] Usually, if the tooth falls out for too long, the bone below the maxillary sinus is gradually consumed due to bone resorption or gasification of the maxillary sinus in the maxillary posterior region, and the bone height in the maxillary posterior region is not enough to place implants. It is necessary to internally lift the maxillary sinus floor to form a bone augmentation space above the jawbone and increase the usable height so that implants can be placed here. [0004] In the prior art, the maxillary si...
