1. A three-point locating modeling method using a three-point locating dental implant locating guide, comprising:
providing a first plate, having a first plate body, the first plate body having a first groove extending along the first plate body, a first slide member being slidably connected to the first plate body, the first slide member having a first through hole corresponding in position to the first groove, the first through hole and the first groove mutually constituting a first locating hole, one end of the first plate body being defined as a first end portion, the first end portion having a first perforation;
providing a second plate, having a second plate body, the second plate body having a second groove extending along the second plate body, a second slide member being slidably connected to the second plate body, the second slide member having a second through hole corresponding in position to the second groove, the second through hole and the second groove mutually constituting a second locating hole, one end of the second plate body being defined as a second end portion, the second end portion having a second perforation, the first end portion of the first plate being pivotally connected to the second end portion of the second plate so that the first perforation and the second perforation are overlapped to constitute a third locating hole, extending directions of the first locating hole, the second locating hole and the third locating hole being arranged parallel to each other;
obtaining oral image data of a patient;
determining a first locating point position, a second locating point position and a third locating point position in the patient's oral cavity according to the oral image data;
aligning the third locating hole of the dental implant locating guide with the first locating point position in the patient's oral cavity after drilling the patient's alveolar bone in the first locating point position via the third locating hole and implanting a first locating pin in the first locating point position of the patient's alveolar bone;
sliding the first slide member and the second slide member and adjusting a pivot angle between the first plate and the second plate for the first locating hole and the second locating hole to be aligned with the second locating point position and the third locating point position in the patient's oral cavity respectively, after drilling the patient's alveolar bone in the second locating point position via the first locating hole as well as in the third locating point position via the second locating hole, and implanting a second locating pin and a third locating pin in the second locating point position and the third locating point position of the patient's alveolar bone in order that the first locating pin, the second locating pin and the third locating pin constitute a three-point locating base; and,
producing a dental mold by using the three-point locating base constituted by the first locating pin, the second locating pin and the third locating pin as a modeling base.
