Disclosed herein is a mini implant. In the mini implant, friction is generated at a tapered portion through screw-coupling between a fixture's post portion and an abutment's post hole, so that the so-called friction-lock technique can be employed to not only completely couple the fixture and abutment without relying on cement or a mallet, but also uniformly maintain connectivity between the fixture and the abutment, regardless of the dental surgeon. The fixture defines the tapered portion at a top of an implanted portion defining screw threads in an outer periphery thereof. The post portion is formed above the tapered portion and defines screw roots. The abutment defines the post hole in a lower, inner region thereof and a prosthesis mount at an upper region thereof. The post hole defines screw threads corresponding to the screw roots of the post portion.
