The present invention relates to an implant stent aid, and more particularly to an implant stent aid for implanting the implant more accurately and safely in the alveolar bone of the patient.

Implant is a type of prosthesis that is used to replace an abnormal or missing tooth, which can be individually treated without damaging adjacent teeth and has a long life. . Since the implant is implanted after drilling the alveolar bone of the patient using a drill or the like, it is most important to perforate the alveolar bone of the patient.

1 is a perspective view showing a conventional stent used to implant the implant, and a state of puncturing using the stent, the stent (S) is a precise shape by making a model of the same shape as the teeth of the patient before implantation Used to find the position, it is made of resin (acrylic) or the like is inserted and fixed to the adjacent teeth (T).

Looking at the process of implant implantation using the stent (S) as described above.

First, the patient's upper and lower mandibular shapes are obtained by using a rubber impression material, and the plaster is poured into the obtained shape to make the same plaster model as the upper and lower mandibles of the patient. The interrelationship of the jaw joints and upper and lower teeth is almost similar to that of the outside of the mouth. Thereafter, a model of the tooth to be joined to the site where the tooth is lost is used and the model is used as a stent. The central part of the artificial tooth model formed on the stent is the position where the implant is placed, and when the hole is formed for the drill, the stent is completed. Typically, the stent is made to be inserted into the surrounding teeth is fixed by inserting in the teeth. The number and location of implants to be placed are determined by comprehensive consideration of the patient's oral condition and X-ray results.

When the stent is completed, the patient's gingival is dissected and the stent is inserted into the remaining teeth. In addition, the position to be punctured is indicated on the upper portion of the patient's alveolar bone with reference to the position of the hole punched in the stent, the drill is inserted from the upper part of the hole of the stent, and then the hole is marked to prepare the implant.

At this time, when the uppermost central portion of the alveolar bone is located at the lower portion of the hole, the drill may be drilled after the drill is vertically positioned at the central portion of the stent hole. If it is small, it is difficult to change the direction of the drill, so that the drilling is not easy, so the diameter of the hole should be large. However, the smaller the diameter of the hole is, the less the fluctuation of the drilling angle due to the less shaking of the drill, but when the diameter of the hole is too small, there is a disadvantage in that the drill cannot be changed by hanging the wall of the hole. On the other hand, if the diameter of the hole is large, it is easy to change the drilling angle, but when the drilling is shaken, an error may occur when the operator determines the drilling angle.

In addition, when the alveolar bone is drilled, the scale of the drill is confirmed on the surface of the alveolar bone. The bone perforation area on the alveolar bone is located deep inside the oral cavity, so that the field of view is narrow and not easy to access. It is not easy to check the scale of the operator.

In addition, as described above, if the scale is not easy to be easily punctured or not punctured as deep as the operator thinks, complications may occur or reperforation may be required.

In addition, the conventional method of puncture using the stent has a high possibility of deviation from the intended position of the operator, as described above, X-ray imaging or damage to the important structures around the possibility to confirm the direction of puncture of the alveolar bone even during surgery In many cases, additional cumbersome procedures to check whether the operation time is longer or more difficult for the operator and the patient.

Therefore, an object of the present invention is proposed to solve the above-mentioned problems, when the hole for implant implant implants stent aid for the implant is mounted on the stent so that the drilling operation can be made more stable, accurate and quick To provide.

Stent aid for implants of the present invention for achieving the object of the present invention as described above, the body having a predetermined length; And a drill insertion hole formed to penetrate the upper and lower surfaces of the body, wherein the opening of the drill insertion hole formed on the upper surface of the body is spaced apart from the center of the upper surface of the body by a predetermined distance.

First, since the perforation means is inserted into the first to fourth embodiments according to the alveolar bone perforation angle, which is determined in advance, it is not necessary to pay attention to the angle change during the procedure, and thus the operation time is shortened and the operation is easy. Therefore, the fatigue of the operator can be reduced accordingly.

Second, the induction of the drill according to the first embodiment to the fourth embodiment can prevent the shaking of the drill during drilling can pierce the alveolar bone stably and accurately.

Third, since the perforation angle predicted and determined outside the oral cavity can be reproduced in the oral cavity as it is during the actual operation, the result after the surgery can be predicted to some extent. Similar to the actual surgical procedure, it pursues perfect parallelism between the various implants on the oral model from outside the oral cavity on the oral model. Even though the gingival detachment is not performed, the drilling angle is performed at the optimal position. By applying the stent to the above first to fourth embodiments, more mechanical results can be pursued.

Fourth, by using the drill tool shown in FIG. 7 in the first to fourth embodiments, there are advantages such as the accuracy and stability of puncturing and surgery in the correct direction, reducing the fatigue of the operator, and reducing the operation time.

Fifth, since the assistive body is standardized, it is possible to use different types of assistive devices as necessary to effectively cope with the surgical conditions.
