It relates to a point drill aid for a procedure.

Commonly used screw implants include soft tissue surgery to open the gums in the area where the implant is to be inserted, bone removal surgery to remove cortical and reticular bones to form points in the alveolar bone, and implants after bone removal surgery. After the stabilization period to ensure adhesion, connect the abutment of the implant out of the gum so that the processed tooth can be inserted, and when the gum is completely improved and the implant is fixed to the bone, a series of processes are produced to join the implant to the implant. It is performed through.

The number and location of implants to be placed are determined in consideration of the patient's oral condition and X-ray results, but conventionally, the position of implants is determined using an initial point drill, depending on the experience and know-how of the operator. .

Conventional techniques for selecting an initial point drill position in an implant procedure are as follows. First, it is used to find the exact location of the implant by making a model of the same shape as the patient's teeth before implantation is made of resin (acrylic) and the like is inserted and fixed to the adjacent teeth. It is a method to set the initial drilling point by drilling in the center of the fixed model tooth. Second, as described in the Republic of Korea Patent Registration 10-0535444 to make the initial drilling point by making the stent aids determined according to the oral condition to the patient. In addition, the operation time is shortened to determine the puncture angle, and the operation is easy, thereby reducing the fatigue of the operator. Lastly, as described in Republic of Korea Patent Registration 10-0829244 it describes a drilling aid for sliding implant implants for forming a plurality of points.

Conventional techniques have often caused excessive perforations or inaccurate positions in the point drill operation, and sometimes caused by complications and re-perforation operations because they were not drilled to a sufficient depth. In addition, if changes occur during surgery considering the patient's oral condition, it takes a long time to produce and change the assisting tool.

In addition, when drilling the alveolar bone, the scale of the drill is checked on the surface of the alveolar bone, so if the bleeding generated during the operation covers the alveolar bone, it is not easy to check the scale of the operator.
