  • Patent number: 10492895
    Abstract: The facebow with double bite forks uses two bite forks. The bite forks are connected to one common handle of the bite fork secured to the facebow frame. The assembly for the two bite forks helps to maintain a predetermined vertical distance of 1.5 centimeters between them. An infraorbital pointer is also attached to the facebow frame. It is secured in place to act as the anterior reference point. The adjustable earpieces inserted into the patient's external auditory meatuses are adjusted to be considered as posterior reference points. This assembly helps to record the facebow and centric relation positions simultaneously.

  • Patent number: 10314672
    Abstract: The retractor is a generally U-shaped device for protecting the cheek and tongue from instruments used during dental and prosthodontic procedures. The retractor has a planar base defined by two spaced arms, a pair of upright shields extending from the arms, and a posterior connector connecting the shields. The base is contoured to grip the tooth adjacent to the tooth to be treated, and thereby, secure the retractor within the patient's mouth.

  • Patent number: 10070946
    Abstract: The device for recording vertical and centric occlusion positions of edentulous jaws is a tool which allows a dental practitioner to maintain maxillary and mandibular record bases (and their respective wax rims) in their respective vertical and centric occlusion positions during transfer of the maxillary and mandibular record bases to a conventional dental articulator. A pair of telescopically adjustable rods are provided for measuring the vertical occlusion position of the patient's edentulous jaws. Each of the telescopically adjustable rods has a selectively adjustable and lockable height, with the opposed ends thereof being releasably secured to the maxillary and mandibular record bases, respectively. The telescopically adjustable rods are also horizontally adjustable with respect to the maxillary and mandibular record bases, allowing the centric occlusion position of the patient's edentulous jaws to be recorded.
