Abstract
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.
