Abstract
Disclosed is a dental implant insertion set including a crown; a fixture which has a hex hole formed therein and of which an insertion angle is set so that the hex hole is aligned corresponding to an arrangement angle of the crown; a guide stent including a stent body formed with a profile set through the three-dimensional procedure guide image to be fixed while covering the periodontal tissue; and an abutment having a hex protrusion formed at a lower portion thereof to be matched with and fixed into the hex hole, such that the crown is aligned and fixed.
Claims9
A dental implant insertion set comprising:
- a fixture configured to be fixed into an alveolar bone and having a hex hole formed therein;
- an abutment including a hex protrusion formed at a lower portion of the abutment and configured to be matched with and fixed in the hex hole, and a guide surface formed at an outer side surface of the abutment to be parallel with one surface of the hex protrusion;
- a crown configured to be aligned with and fixed to the abutment;
- and
- a guide stent including a stent body configured to be fixed in a patient's mouth and to cover a periodontal tissue in the patient's mouth, coupling hole formed at the stent body, and a sleeve inserted into and fixed in the coupling hole,
- wherein the sleeve has a guide hole formed at an inner circumference of the sleeve to guide an implant drill, and a guide protrusion formed at an outer circumference of the sleeve to guide an insertion angle of the fixture,
- wherein the guide protrusion of the sleeve has a width as the same as a width of the guide surface of the abutment.
A method of manufacturing a dental implant insertion set, comprising:
- obtaining a three-dimensional image of periodontal tissue in a patient's mouth through a CT scan and a three-dimensional outer shape image corresponding to the three-dimensional image through an oral scan;
- obtaining a three-dimensional procedure guide image by matching the three-dimensional image and the three-dimensional outer shape image;
- and
- manufacturing a fixture configured to be fixed into an alveolar bone and having a hex hole, an abutment, a crown having a coupling groove at a lower portion of the crown, and a guide stent,
- wherein the abutment includes a hex protrusion formed at a lower portion of the abutment and configured to be matched with and fixed in the hex hole, a guide surface formed at an outer side surface of the abutment to be parallel with one surface of the hex protrusion, and a coupling protrusion formed at an upper portion of the abutment and configured to be matched with the coupling groove of the crown,
- wherein the guide stent includes a stent body having a coupling hole positioned at a preset insertion position of an implant according to the three-dimensional procedure guide image, and a sleeve having a guide hole formed at an inner circumference of the sleeve to guide an implant drill and a guide protrusion formed at an outer circumference of the sleeve to guide an insertion angle of the fixture,
- wherein the guide protrusion of the sleeve has a width as the same as a width of the guide surface of the abutment.
