  • Edentulous surgical guide
    Patent number: 11109942
    Abstract: A dental surgical drill guide assembly and method includes a surgical guide housing and a base frame that fits to both gum tissue and one or multiple small areas of jawbone. The apparatus may be configured to accurately place dental implants according to planned positions. Such apparatus may increase the stability of the surgical guide by clasping and/or contacting the jawbone, while improving the overall fit and minimizing the need of invasive surgery and flapping by also clasping and/or contacting selected areas of the gum tissue at the same time. Self-locking alignment members aid in easy removal, and re-installation, of the surgical guide housing to the base frame.

  • Dentistry tool
    Patent number: 11045287
    Abstract: A drill bit and method for normalizing bone is provided. The drill bit has a non-round drill bit core that is adapted to cut hard bone and to not cut soft bone.
