The present invention relates to a tooth-borne guide plate, a mucosa-borne guide plate, a bone-borne guide plate, and preparation and application methods therefor. The method for preparing a tooth-borne guide plate comprises: a) bonding a radiopaque material to teeth, bonding the radiopaque material to the gingival mucosa or/and bonding the radiopaque material to other anatomical features; b) performing CBCT photography, and acquiring CBCT data with radiopaque material information; c) acquiring oral cavity surface STL data with radiopaque material information; d) matching the CBCT data with the STL data; e) determining the positions of an implant and a retention pin; f) generating a base guide plate; g) generating an in-place guide plate; h) generating an implant guide plate; and i) generating a repair guide plate. By means of the tooth-borne guide plate, the mucosa-borne guide plate, the bone-borne guide plate, and the preparation and application methods therefor provided in the present invention, the precision and success rate of data matching can be improved, thereby improving the patient's comfort, reducing the number of subsequent visits, and reducing clinical medical costs.
