Abstract: A dental model articulator includes two hinge-jointed arms, each arm having segments connected to a hinge joint having mating elements, one integral to each segment of an arm. One element includes two cymbals that are coaxial on a major hinge axis and concave facing which resiliently capture between them a node of the mating element on the other segment which has the form of opposed, outwardly facing convexities. Multiaxial motion between the segments of each arm is accomodated by the rotation of the convexities of the node within detents at the apices of the cymbals. The extremities of each arm terminate in cylindrical rod-like elements that are parallel to the major hinge axis. The rods engage with transverse, cylindrical channels either cut-in, molded-in or affixed to the models. With the models positioned in centric occlusal relationship and the arms adjacently positioned and engaged, the four rods are adhesively fixed in the channels. Once fixed, the two hinge joints together define a single hinge axis posterior and interjacent to the models. Further, each hinge joint can allow the node elements to release from the axis detents and slide between the cymbals to permit protrusive and lateral masticatory motions between the dental models.

Abstract: An improved ball-and-socket joint for use with dental model articulators of a vertex type comprising two brackets hinged together at one end and each connected at the other end by a ball-and-socket joint to a separate one of two stone plates bearing dental castings. The ball-and-socket joints have releasable mechanical means for affixing the ball in the socket after the plates have been aligned for bite and occlusal fit between the dental castings. Affixing the ball in a socket is achieved by mechanically adjusting the diameter of one relative to the other of the socket and the ball to create a friction force that affixes the ball in the socket. In one embodiment, the mechanical means comprises a C-clamp having a concave band with a cross-sectional diameter substantially equal to the ball diameter and a gap to allow the ball to be snap-fit into the C-clamp. A bolt through flanges at the ends of the C-clamp is used to reduce a gap between flanges, thereby increasing without limit the frictional clamping force on the ball. In another embodiment, the ball is inserted into a truncated spherical cavity formed on a stalk in four parts with gaps between the parts. The ball gaps permit the ball to be snap-fit into the spherical cavity serving as the socket for the joint. A bolt threaded through the bracket base and stalk that supports the ball is turned to drive it between the four parts in the socket, thereby spreading apart the four parts of the ball in the cavity to produce the necessary friction force between the ball and cavity wall to affix the ball in the socket.

Abstract: The present invention provides a low-cost, durable dental articulator that does not require the use of toxic or messy glues. The articulator is composed of a pair of bands that encircle and are attached to the plaster upper and lower teeth bases of the model, a pair of spheres that mechanically attach to the bands at any of several positions corresponding to the rear of the mouth on the dental model, and a hinge assembly simulating movement of the jaw and made of two arcs attached to each other at their ends by a hinge mechanism and having clamps at their apexes for attaching to the spheres. The dental model can be adjusted to mimic the occlusion of the patient by adjusting the position at which the spheres are attached to the bands and the position of the spheres in the clamps.

Abstract: An articulator that can be recalibrated easily in the field. The articulator has left and right condyle elements that resemble barbells, with an inner sphere, an outer sphere, and a shaft connecting the inner and outer spheres together. In the preferred embodiment, the outer spheres are releasably fixed to the lower frame member by clamping members, and the inner spheres are pivotably mounted to the upper frame member. To calibrate the articulator, the clamping members are loosened, an alignment fixture is installed to ensure that the articulator is in proper alignment, and then the clamping members are tightened into position, fixing the outer spheres in the properly-aligned position.

Abstract: A dental and soft tissue scanning method and system is disclosed which uses fast laser line scanning techniques of negative image impressions, whereby an array of electronic data is generated. In operation the array of negative image scan data is generated by a scanner 60 and provided to a processor 501. The negative image scan data may be saved in a memory device 504 as a permanent record of the baseline condition of the patient's teeth, or temporarily prior to one of several other options. The processor 501 may convert the data to a positive image for display on the video display unit 503 for teaching or educational purposes with the patient. Alternatively, the positive information data may be transmitted to a remote PC 505 for storage, study by a consulting dentist (or physician), or fabrication of a study cast by fabrication device 507. These and other options may be selected by the user of computer 500 via the input device 506. The programming operation of the processor 501 provides for scanning each of the upper and lower impressions and the bite registration impression. These scans provide the information necessary to create an electronic equivalent of a physical study cast.

Abstract: A positive mold for use in creating an orthodontic appliance is produced by obtaining a digital dentition model, such as a 3D geometric surface model or a 3D volumetric image model, that defines the shape of an orthodontic appliance and then altering the digital dentition model to remove a portion that does not affect the shape of the orthodontic appliance. The altered digital dentition model then is used to construct a positive mold for the orthodontic appliance. Processing circuitry, such as a programmed computer, is used to obtain and alter the digital dentition model. A rapid prototyping device, such as a stereolithography machine, is commonly used to construct the positive mold.

Abstract: An implant comprising an internal bore having an opening at one end of the implant is initially fixed within a patient's mouth. A support post on which a final artificial prosthesis will be mounted is attached to the implant by allowing a portion of the post to extend into and attach within the bore of the implant. The post generally extends supragingivally from a base at or beneath the gum surface and contains a retention bulb to assist in registering the axial orientation of an impression cap and the final prosthesis. The impression cap is then placed over the post to assist in taking an impression of the relevant dental region. The impression cap contains means to allow the retention bulb to snap onto the impression cap. After the impression material is placed to surround the impression cap, post and implant, the impression material and impression cap are removed. A healing cap is placed on the post and acts as a temporary tooth able to last within the patient's mouth for several months.
