A DENTAL IMPLANT DRILL HAVING A MULTI-STEP STRUCTURE

摘要

Provided is a dental implant drill having a multi-step structure, in which a multi-step portion including a plurality of steps with blades formed thereon is provided so that thrust loads applied to the dental implant drill are constant by increasing a thrust load applied to an external circumference of the dental implant drill and reducing a thrust load applied to the center of the dental implant drill, in order to minimize a cutting temperature, so that chips are smoothly discharged by regularly distributing a cutting force to the blades, in order to minimize a cutting temperature. Also, a drilled hole in which a fixture can be implanted is formed by a single drilling operation and the time required for an implant operation is reduced. Further, the dental implant drill includes a guide portion so as to accurately drill an alveolar bone along a desired path.
