  • the present invention relates generally to dental assemblies.
  • the craniofacial region of the body includes the region of the head comprising the craniofacial bones, including the maxilla (i.e., the upper jaw bone), the hard palate and the nose, and the mandible (i.e., the lower jaw bone).
  • Many dental procedures require sufficient bone height for proper anchoring and osteointegration of objects, such as implants, in the craniofacial region. If there is insufficient bone height, such as insufficient alveolar bone height, augmentation of the deficient bone may be required.
  • the maxillary sinus membrane located in the upper jaw
  • the inferior alveolar nerve located in the lower jaw
  • Bone distraction followed by osteogenesis is another example of a method for augmentation of deficient bone. Bone distraction generally involves cutting a bone and separating it in a controlled manner. As the separation of the bone at the fracture site takes place, new bone is formed (i.e., by osteogenesis) in the intervening space created by the separation.
  • distraction used in dental procedures generally requires a skilled dental surgeon and great care so as not to damage nerves in the region.
  • the present invention seeks to provide improved dental assemblies for, inter alia, detecting and locating nerves while drilling, osteogenesis of implants, and alternative apparatus for bone distraction, wherein the periosteum, not the bone, is augmented.

Such purposes include, for example, localization of the nerve for the administration of regional anesthesia or to avoid cutting the nerve during sectioning or excision of tissue.
  • Nerve localization via the application of electrical energy is based on the fact that a pulse of electricity may stimulate a nerve fiber to contract an innervated muscle or cause paresthesia in the case of sensory nerves.
