This creation relates to an artificial root extraction device that uses a nesting body to unscrew an artificial root implant. The artificial root removing device is composed of a force applying wrench and a sleeve body； the force applying hand has a handle and a fitting portion； one end of the sleeve body is a threaded tapered end, and the special cone The reverse thread design has a thread depth of less than 0.05 mm, which has a strong fitting effect on the teeth of the implanted body, and a corresponding end is provided with a card end to engage with the fitting portion of the force plate. The utility model mainly adopts the threaded tapered end of the sleeve body, which can be applied to the implant tooth gauges M1.4, M1.6, M1.8, M2.0, and the forceps are used to unscrew the bone bone. The implants in the tank can be used with different instruments without different tooth gauges. The artificial root extraction device can prevent the bone from being damaged and can easily take out the implant, which is quite practical.本創作係有關一種人工牙根取出裝置，其係利用套合本體將人工牙根之植體旋出。該人工牙根取出裝置係由施力板手及套合本體所組成；該施力板手具有一握柄及一嵌合部；該套合本體之一端係為具有螺紋之錐形端，其特殊錐體逆螺紋設計，螺紋深度低於0.05mm，對於卡住植體內牙有強烈的嵌合感，對應端開設有一卡掣端，以與施力板手之嵌合部結合。其主要係於利用套合本體之具有螺紋之錐形端能適用於植體內牙規M1.4、M1.6、M1.8、M2.0，藉由施力板手以旋取出該牙骨槽內之植體，無需不同牙規得適用不同器械，一支即可多用。利用該人工牙根取出裝置可防止骨頭被破壞，並能容易將植體取出，具有相當之實用性。
