Description

Implant surgery guide

The present invention relates to an implant surgery guide device, and more specifically, to an implant surgery guide device having a shape in which a side surface of a guide hole is opened to a gingival part in order to improve the convenience of surgery.

Implants are restorations that are used to replace severely damaged teeth. An artificial tooth root made of a special metal (mainly titanium or titanium alloy) is transplanted into the alveolar bone in the missing part of the tooth. After the artificial tooth root and alveolar bone tissue are condensed and fixed, an artificial tooth is formed by using the artificial tooth root, so that the artificial tooth has almost the same feeling as its own tooth, and can enjoy the daily dental surgery method or the surgically operated as described above. Artificial teeth collectively.

Compared with surgical methods using dentures, dental bridges, and the like, the aforementioned implants have the advantages of not damaging surrounding teeth other than the teeth requiring surgery, having a long life, and being very similar to natural teeth, and have recently attracted attention.

A simple explanation of the above-mentioned implant surgery method is as follows: First, the alveolar bone is exposed by incision of a gingival part (gingival) of a patient to undergo implant surgery. Next, a position for inserting the implant is determined in the exposed alveolar bone, and a part of the alveolar bone is excised by a perforating tool such as a drill device at the position to form a hole for implantation of the implant. Finally, implantation in the hole formed includes After the fixtures and abutments are implanted, the gums are covered to complete the implant setting.

Generally, in implant surgery, after the alveolar bone is exposed by incision of the gingival part, it is difficult to determine the exact position and direction of the perforating work when the alveolar bone is perforated with a drill. Therefore, surgical guidance is generally used. Device.

However, since the side portion of the conventional surgical guide device is not opened, and due to the height of the vertically protruding guide hole, if the patient's inter-jaw distance is not sufficient as the molar tooth portion, there is a problem that the surgical drill device cannot enter.
