Problems solved by technology

[0004] However, this operation is performed under blind vision. Although the operation method is simple, it is difficult to operate. It is difficult to accurately control the percussion force based on hand feeling and hearing judgment, which may easily cause mucosal perforation, and mucosal perforation is difficult to remedy.
Due to the limitation of the mouth opening, it is difficult to apply it in the maxillary second molar area, an

Embodiment approach

[0033] An embodiment of a maxillary sinus bottom lifting device of the present invention is as follows:

[0034] Prepare the implant socket in the edentulous area at the back of the maxilla to 0.5-2 mm from the bottom of the maxillary sinus. The diameter of the implant socket is smaller than the outer diameter of the base 1. Screw the screw 2 into the base 1 and then screw the base 1 into the implant socket through the screw 2. Tighten the base 1 in the implant socket by using the first force receiving mechanism 3 as the fulcrum through the rotating mechanism, and then apply force to the screw 2 by using the second force receiving mechanism 8 as the fulcrum through the rotating mechanism. At this time, the maxillary sinus floor passes through the screw rod The rise of 2 is improved, and the antagonistic force of the screw pushing and lifting the maxillary sinus floor comes from the friction force generated after the base is screwed into the bone wall of the implant socket and t...

Abstract

The invention discloses a maxillary sinus floor lifting device comprising a screw rod and a base; the base is of a hollow columnar structure, the outer surface of the base is provided with a self-taping thread and a first stress mechanism; the self-tapping thread and the first stress mechanism are partitioned by a check ring; the inner surface of the base is provided with an inner surface thread, the thread direction of which is accordant with that of the self-tapping thread; the screw rod is of a columnar structure; the surface of the screw rod is provided with a screw-rod thread and a second stress mechanism, wherein the screw-rod thread is matched with the inner surface thread,; and the bottom of the screw rod is provided with a stress application plate. According to the invention, the base and the screw rod are combined, arranged and fixed in a planting hole; and the screw rod runs through the base and applies a lifting force to the maxillary sinus so that the maxillary sinus is lifted to a predetermined altitude. The maxillary sinus floor lifting device can be used for lifting the maxillary sinus slowly under accurate control and also avoiding discomfort caused by beating; more preferably, assistant tools or means are not required for fixing the base; in addition, the base has a small function in lifting the altitude of the maxillary sinus.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to a lifting device and method for maxillary sinus bottom. [0002] Background technique [0003] At present, the most advanced method for the treatment of missing teeth is dental implant restoration. However, in the maxillary sinus area, the absorption of the alveolar ridge and the pneumatization of the maxillary sinus often cause insufficient bone height. Maxillary sinus lifting surgery can solve the problem of insufficient bone height. That is to create a space between the maxillary sinus floor and the maxillary mucosa, and place bone or bone substitutes to increase the distance from the alveolar crest to the maxillary sinus floor, making it possible to place implants. Sinus lift can be divided into closed sinus lift and open window sinus lift. Maxillary sinus lift refers to the preparation of implant sockets on the top of the alveolar ridge. When the preparation reaches 1-2 mm t...
