Methods for personalized root-shaped implant

A method for manufacturing a personalized root-shaped implant, comprising:

• obtaining a personalized root-shaped implant model;
• and
• manufacturing a personalized root-shaped implant and a die of the personalized root-shaped implant according to the personalized root-shaped implant model;
• wherein obtaining the personalized root-shaped implant model comprises:
• capturing a CBCT image of a missing teeth area of a patient;
• performing image segmentation and model reconstruction on the CBCT image and obtains a full-mouth original teeth model;
• selecting a target tooth model from the full-mouth original teeth model;
• and
• processing the target tooth model in a preset strategy such that the personalized root-shaped implant model is generated;
• wherein the processing the target tooth model in a preset strategy comprises:
• determining a direction of the target tooth model and a coordinate of the target tooth model;
• determining a cutting plane of the target tooth model according to a height of the target tooth model;
• cutting the target tooth model at the cutting plane by using a manner of topological cutting, such that a cut-off portion of the target tooth model is obtained;
• performing a diameter increasing and decreasing process on the cut-off portion and obtaining a personalized root-shaped implant STL model;
• determining a center of an upper largest internally-connected circle of the personalized root-shaped implant STL model according to the personalized root-shaped implant STL model;
• and
• obtaining an upper connection structure model of the personalized root-shaped implant STL model according to the center of the upper largest internally-connected circle of the personalized root-shaped implant STL model such that the personalized root-shaped implant model is generated.
