A stopper storage case has openings and drill blade insertion paths. The openings are large enough to allow a spring-like engagement portion of the stopper to pass. Each drill blade insertion path is large enough to allow a drill blade to pass. Concave parts extend from the respective openings to the drill blade insertion paths and can store stoppers of different lengths. Each of the concave parts has a protrusion to be engaged in a groove in the outer peripheral surface of the stopper. Stopper holding overhangs formed at the top of each concave part are elastic enough not to interfere with insertion of the stopper from above into the concave part and removal of the stopper from inside the concave part.

Stopper storage case

In a hard material made stopper housing case to house a plurality of cylindrical stoppers for defining a drill blade entering depth of a dental implant fixture embedding hole at a jawbone when performing a dental implant treatment, the stopper has a spring-like locking part to be locked with a flange part projected from a shank part of a drill, the stopper housing casehas concave partsprovided in parallel and capable of respectively housing the stopper Y, and each of the concave partsincludes, at one side, a flange part insertion pathhaving a size preventing the spring-like locking part from falling out and being capable of inserting the flange part, and further includes, at another side opposite to the one side, a drill blade part insertion pathcapable of inserting the blade part of the drill X.
