BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an implant guide assembly, and more particularly, to an implant guide assembly capable of easily, quickly, and precisely setting a drilling depth in a drilling operation for implant placement.

A dental implant drill refers to a small, fast spinning drill used in dental procedures, and is used primarily to remove stubborn teeth or to remove the sharpened parts of crowns before putting them on.

A dental implant refers to a fixture (placed on the gums and gums) that is placed in or on the jaws for the purpose of restoring a missing tooth, It is a dental treatment method that restores the function of the natural teeth by implanting a biocompatible implant body on the jaw bone which has been enlarged so that it can be sufficiently wrapped through additional operations such as bone grafting and osseointegration on the jaw bone.

After the osseointegration, which is a morphological, physiological and direct coupling between the jawbone and the surface of the implanted body, which is normally maintained, is performed, the bone is subjected to a bone remodeling process of the peri-implant jaw. There are many types of implants, but screw implants have recently been used.

To perform the dental implant procedure, first anesthetize and incise the gums, open the incised gingiva to reveal the shape of the jawbone, and then drill using a dental implant drill at the implant site. In the jaw bone, the implant creates a hole into the body. Drilling should be done in the exact position where the implant body will be placed, and holes should be formed with the correct drilling direction and drilling depth. Drilling is done several times until it reaches the size of the implant diameter, then carefully implant the implant.

At this time, in order to perforate the hole in which the implant is to be inserted in the correct drilling position and direction, the drilling proceeds with the stent having the hole for guiding the drill bit inserted into the gum. In the hole formed in the stent, a metal sleeve for guiding the drilling direction of the drill bit is engaged while maintaining contact with the drill bit.

In order to work with an accurate drilling depth during drilling for such an implant operation, the depth of the drilling member should be indicated on the outer periphery of the drilling member or additional additional equipment and components should be used.

However, in the case of the former, the accuracy of the procedure may vary depending on the skill of the practitioner, and there is a problem of increasing the fatigue of the worker due to a considerable care and concentration in the work. In the latter case, additional costs of additional equipment and components are incurred Each implant system had to be prepared separately.

Therefore, it is required to develop a drilling depth control means with stable reliability which does not determine precision according to skill of a practitioner and does not incur cost burden due to construction of a complicated system.
