obtaining a gypsum model by using gypsum after taking a model from the oral cavity of a patient, selecting a proper area on the gypsum model to place a plurality of steel balls, wherein the position points where the steel balls are placed should avoid a planting area to form a fixed triangular row structure, so that the guide plate model is convenient to reset at the later stage;

forming the guide plate diaphragm on the plaster model by using a negative pressure forming device to obtain a main body structure of the guide plate diaphragm;

trimming the main structure of the guide plate diaphragm along the tooth form, and grinding and polishing, wherein steel balls on the plaster model are transferred to the main structure of the formed guide plate diaphragm;

the main body structure of the guide plate diaphragm with the steel balls is brought into the oral cavity of a patient, the CBCT is shot after the complete fitting and positioning are confirmed, and a 3D steel ball model is established in a corresponding steel ball position through matching by medical three-dimensional editing software;

simulating and setting the angle and the direction of an implant to be implanted in an area to be implanted, and establishing a 3D guide rod model;

exporting the 3D guide bar model into an STL format file, and printing the guide bar model by using a 3D printer;

the main structure of the diaphragm of the guide plate is clamped into a printed guide rod model, a stable position is obtained by using steel balls, and holes are formed in the corresponding positions of the guide rods, so that the main structure of the diaphragm of the guide plate can be smoothly positioned;

selecting a guide plate ring matched with the guide rod and sleeving the guide rod;

and uniformly coating dental base resin on the main body structure of the diaphragm of the guide plate and the guide plate ring, trimming redundant parts after solidification, polishing, finishing the manufacture of the guide plate, and finally soaking the guide plate in a disinfectant for disinfection to be used during an operation.

As an improvement, the diameter of the steel ball is six millimeters.

Compared with the prior art, the invention has the advantages that: when the guide plate needs to be used, the guide plate for guiding the preparation of the hole of the dental implant can be obtained according to the nine steps. The steel ball can be replaced by steel bar, lead ball, lead block, aluminum bar, resin or other material objects capable of blocking X-ray. The guide plate for guiding the preparation hole of the dental implant and the manufacturing method thereof greatly reduce the requirements of manufacturing equipment, can be completed by a doctor personally, and have the advantages of simplicity, high efficiency, low cost, high practical value and high popularization value.
