A safe maxillary sinus elevator that directly adjusts the maxillary sinus so that the maxillary sinus can be safely raised in a desired direction as much as desired, and a treatment method using the same
The present invention relates to a safety subantral membrane lifter comprising a bone-fixing unit including a bone-fixing arm mounted on the top of the bone-fixing unit, a bone-fixing unit body arranged at the lower end of the bone-fixing unit, and a bone-fixing unit support arranged at the lower end of the bone-fixing unit body. The bone-fixing unit comprises: said bone-fixing unit body, which is cylindrical and which has an open end and a space formed therein； said bone-fixing arm arranged at one end of the bone-fixing unit body and which is inclined toward one end thereof； two side blades protruding outwardly from both sides of the bone-fixing unit body and formed in the vertical direction so as to be sharp； and said bone-fixing support arranged at the lower end of the bone-fixing unit. The safety subantral membrane lifter of the present invention may directly adjust the subantral membrane to safely lift the subantral membrane in a desired direction by a desired distance.本発明は、骨固定部と、骨固定部の上端に設けられた骨固定腕と、骨固定部の下端に設けられた骨固定部胴体と、骨固定部胴体の下端に設けられた骨固定部支持台とで構成され、上記骨固定部は、内部に空間部が形成され、端部が開放された円筒形の骨固定部胴体と、上記骨固定部胴体の端部は、端にいくほど傾斜するように形成された骨固定腕と、骨固定部胴体の両側面にはそれぞれ外部に突出して垂直に鋭く形成された二つの側面刀とで構成され、骨固定部の下端に設けられた骨固定部支持台を含んで構成された上顎洞膜を直接調節して上顎洞膜を所望の方向に所望するだけ安全に挙上できるようにした安全上顎洞膜挙上器に関する。【選択図】 図１
