Method and System for Generating a Dental Implant Surgical Drill Guide

摘要

A method and system for producing a dental implant surgical guide is disclosed. A patient-specific virtual model is generated using image data specific to a patient and virtual dental implants. The virtual model aligns the image data with the virtual dental implants using modeling software. A virtual mold is generated from the virtual model, and a physical mold is generated from the virtual mold. The physical mold is covered with a thermoplastic sheet via a thermoforming process. Excess thermoplastic material is trimmed off after the thermoforming process to produce a thermoformed piece. Metal tubes corresponding to each the virtual dental implants are placed onto the physical mold denoting the position, trajectory, and depth of the one or more virtual dental implants. A dental implant surgical guide that contains the thermoformed piece with the one or more tubes is produced.

1. A method comprising:
receiving patient-specific image data comprising a plurality of two-dimensional images; identifying a set of two-dimensional anatomical landmarks from the plurality of two-dimensional images of the patient-specific image data; receiving a patient-specific virtual model; identifying a set of three-dimensional anatomical landmarks from the patient-specific virtual model; aligning the patient-specific image data and the patient-specific virtual model in a three-dimensional space by matching the set of two-dimensional anatomical landmarks rendered in the three-dimensional space and the set of three-dimensional anatomical landmarks.
