Abstract

The application discloses a dental-implantation guide plate tool. The dental-implantation guide plate tool comprises a basic handle and at least one movable handle, wherein one end of the basic handle is provided with an extended drum-shaped structure; one end of at least one movable handle is provided with a penetrating through hole with the inner diameter same as that of the drum-shaped structure; the at least one movable handle is stacked on the basic handle in sequence, so that the drum-shaped structure and the penetrating through hole are superimposed to form a smooth channel; and the other end of the basic handle and the other end of the at least one movable handle can rotate around a common pivoting shaft. The dental-implantation guide plate tool disclosed by the invention has the advantages that the drilling depth of a bone drill can be conveniently and accurately controlled and the unfavorable condition of causing maxillary-sinus membrane perforation in the process of maxillary sinus floor elevation can be avoided.

Description

Technical field [0001] The application relates to the field of medical devices, in particular to a dental implant guide tool. Background technique [0002] When the maxillary molars and bicuspid teeth are missing, the maxillary sinus is often accompanied by the expansion of the sinus cavity, which makes the bone wall at the bottom of the maxillary sinus thin, so that there is not enough bone for dental implant restoration. According to Schlichting's statistics, in 57% of the maxillary posterior areas with missing teeth, 4mm long oral implants cannot be used, and 81% cannot use 6mm long implants. (Schlichting, I., La-cina, D. and Fischak-Treitl, B. (2017) Sinus Lift versus Short Implants: Results of a Pro-spective Radiologic Study and Critical Re-view of Minimally Invasive Transcrestal Si-nus Lift Procedures. Open Journalof Sto-matology, 7, 1-24. http: / / dx.doi.org / 10.4236 / ojst.2017.71001 ). Therefore, the maxillary sinus lifting bone graft is an indispensable surgical method for...
