  • Patent number: 8892235
    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.

  • Publication number: 20130023888
    Abstract: A dental implant surgical guide system is disclosed. A surgical guide is placed onto a patient's mouth. The surgical guide has one or more tubes for accepting detachable drill guide heads. The detachable drill guide heads are placed into a tube of the surgical guide using a handle. The handle has an attach/detach mechanism. A first drill guide head having a first inner diameter is attached to the handle to guide drilling of a first hole. The first drill guide head is removed using the attach/detach mechanism to accept a second drill guide head having a second inner diameter to guide drilling of a second hole.
