Guide pin for dental implant surgery
View Patent ↗Provided is a guide pin for dental implant surgery, providing guidance so that a practitioner easily determines a location and angle of an alveolar bone of a patient when forming an implant hole in the alveolar bone to place an implant in the alveolar bone. By using the guide pin for dental implant surgery according to the inventive concept, a practitioner may perform the surgery by determining an accurate location and shape of the alveolar bone of the patient when drilling an implant hole in the alveolar bone, and thus, the success rate of the implant surgery may be increased.
1. A guide pin for dental implant surgery, comprising:
an insertion portion, extending in a length direction from a first end to a second end, comprising a first surface and a second surface opposite to the first surface, and configured to be inserted to a location directly between an alveolar bone and a gum, wherein the first surface is configured to face the alveolar bone, and the second surface is configured to face the gum; and
a guide portion, coupled to the insertion portion and extending from the first end of the insertion portion, and configured to be exposed outside of the gum and configured to guide an inclination during a formation of an implant hole in the alveolar bone when the insertion portion is inserted to the location,
wherein at least a portion of the first surface of the insertion portion curves toward the second surface at the first end of the insertion portion, and at least a portion the second surface of the insertion portion bends toward the first surface at the second end of the insertion portion.
2. The guide pin for dental implant surgery of claim 1 , further comprising a support portion protruding in a connection portion between the insertion portion and the guide portion.
3. The guide pin for dental implant surgery of claim 1 , wherein the insertion portion further comprises a further curved portion that is bent away from the second surface of the insertion portion at the second end of the insertion portion so that the insertion portion is configured to be inserted between the alveolar bone and the gum by separating the alveolar bone and the gum.
4. The guide pin for dental implant surgery of claim 1 , wherein the second surface of the insertion portion is convexly formed in a direction away from the first surface.
5. The guide pin for dental implant surgery of claim 4 , wherein a ridge protruding from the second surface of the insertion portion extends along the length direction of the insertion portion.
6. The guide pin for dental implant surgery of claim 4 , wherein a plurality of protrusions are formed on at least a portion of the second surface of the insertion portion.
7. The guide pin for dental implant surgery of claim 1 , wherein the guide portion has a polygonal cross-section or includes a concave-convex portion surrounding an outer circumference of the guide portion so that the guide portion is easy to grasp.
8. The guide pin for dental implant surgery of claim 1 , wherein at least one fixing groove extending in the length direction is formed in the insertion portion.
9. The guide pin for dental implant surgery of claim 2 , further comprising an auxiliary insertion portion protruding from the support portion in a direction parallel to the insertion portion so as to prevent shaking of the guide portion that is inserted between the alveolar bone and the gum.
