Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an implant placement guide device,

The present invention relates to an implant placement guide device, and more particularly, to an implant placement guide device capable of positioning a fixture at a planned position, angle, and depth in an implant procedure.

A dental implant operation generally includes an artificial tooth structure (not shown) formed by affixing a fixture, which is an artificial tooth, to an alveolar bone and fixing the tooth prosthesis to the artificial tooth root, .

 Generally, implants are made of a titanium fixture, an abutment fixed on the fixture, an abutment screw securing the abutment to the fixture, and an abutment screw fixed to the abutment. And a crown as an artificial tooth.

These implants can be applied only to the lost area without damaging adjacent teeth or surrounding tissues around the lost tooth, delaying the absorption rate of the bone tissue by supporting the bone tissue, and providing the same masticatory force as the natural teeth And it can form almost the same aesthetic sense as the natural difference in appearance. Thus, recently, implants have been widely used as dental procedures for restoring damaged or lost teeth.

Meanwhile, the conventional implant procedure includes a first step of placing the fixture in the alveolar bone, and a step of fixing the final crown after waiting for a time (3 to 6 months) when the fixture is fusion-bonded to the alveolar bone.

The primary procedure includes a gum removing step of opening the gum of the tooth missing part, a multistage drilling step of forming a perforation to which the fixture is to be inserted, and a step of fixing the fixture and coupling the temporary tooth to the fixture .

At this time, a fixture is placed on the perforation formed through the drilling step. A hexa hole is formed on the inside of the fixture, and a temporary tooth (a healing abutment / cover screw) or a portion of the abutment A hexahedron is inserted and fixed.

Recently, by applying digital imaging technology without opening the gums, the bone condition of the patient is precisely analyzed before implantation in 3D image, and the position and direction of the implant are determined, and the surgical guide is made so that the implant can be placed in this direction This guide can be used to implant implants.

However, it is useful to drill a guide hole of a sleeve of a conventional surgical guide into a smooth cylindrical shape without a helix at a placement position of a fixture. However, when the fixture is rotated, a helical implant fixture rotates, There is a problem that it is difficult to arrange both the placement angle of the hexa hole and the depth of the fixture to the planned position at the same time.
