Abstract: A prosthodontic casting is formed from an implant osseointegrated within a bone and an impression coping coupled with the implant. An impression coping spacer circumscribes a supra-mucosal portion of the impression coping. A relatively high viscosity casting composition is applied to openings in a tray, and then the tray and relatively high viscosity casting composition placed to encompass the supra-mucosal portion of the impression coping and the impression coping spacer. The relatively high viscosity casting composition is at least partially cured, and then the impression coping spacer is extracted from the casting composition. This creates a void about the impression coping. An impression casting composition is then injected into the void and cured to form the prosthodontic casting. The now substantially cured combination casting composition and impression casting composition is removed from the implant, and subsequently used to guide the formation of a dental prosthesis.

Abstract: A dental prosthesis for cattle, and method for mounting it, that includes mounting fastening members in the animals incisor, away from the central nerve and towards in the inner side of the incisor. Tying the incisors individually with surgical wire and to a support plate with through holes to immobilize the relative movement of the incisor with respect to each other. A malleable metallic overdenture is then mounted over the teeth and metallic infrastructure conforming to the incisors to define a conforming overdenture. An adhesive bonding agent is used to mount the overdenture to the incisors and the anchorage structure with retention fastening members that transversally pass through the overdenture and between the incisors to further secure the overdenture to the cured boding agent.

Abstract: A multi-cladding optical fiber includes a core that conveys visible light used by a scanner for imaging a site within a patient's body, and an inner cladding that conveys high-power light, such as infrared light, used for providing therapy to site. The distal end of multi-cladding optical fiber is driven to scan the site when imaging or rendering therapy using an actuator. High-power light is coupled into inner cladding at proximal end of optical fiber using several different techniques. Some techniques use an axicon to direct the high-power light into the inner cladding, while visible light is coupled directly into the core. Another technique uses a multimode optical fiber in a coupling relationship with the multi-cladding optical fiber, to transfer high-power light from a core of the multimode fiber into the inner cladding of the multi-cladding optical fiber.

Abstract: An aesthetic ceramic material is combined with a resilient metal to obtain an aesthetic self-ligating appliance with an easily operable latch mechanism. The appliance uses a door assembly that includes a ceramic ligating cover coupled to a resilient clip pivotable about a hinge mechanism. The clip functions as a latch to reversibly secure the clip and ligating cover to the appliance and retain an archwire in an archwire slot, and is capable of providing active ligation whereby the clip elastically deflects while directly or indirectly providing a continuous force to the archwire. Advantageously, the clip has a configuration that allows an orthodontic practitioner to pivot open the door assembly with minimal force while preventing the inadvertent opening of the door assembly as a result of normal forces applied by the archwire against the door assembly during the course of treatment.

The device includes at least one spring element and at least one retention element. At least one spring element is a leaf spring element which is made of superelastic material and connected by one of its end to a removable female component or the installed male component of the dental prosthesis and has a convex part on its second end for tight friction contacting with the retention element of opposite component of the dental prosthesis.

Abstract: A disposable nozzle for use on the discharge end of the barrel of a needleless injector is threaded onto the front end of a holder mounted in the barrel. A resilient detent extending outwardly at an acute angle from the inner wall of a recess in the rear end of the nozzle repeatedly enters and exits notches in a sleeve on the holder when the nozzle is mounted on the holder providing an audible signal that the nozzle has not been used. Reverse rotation of the nozzle during removal from the holder results in breaking of the detent. Thus, mounting of a used nozzle on the holder would not be accompanied by a signal that the nozzle is unused.

Abstract: An orthodontic assembly for moving selected teeth of a patient includes a hollow aligner shell that fits over a set of selected teeth. The aligner shell supports a series of tooth moving elements, such as magnets or metal engagement plates that are fixed in place in alignment with the selected teeth. Metal plates or magnets are affixed to the selected teeth and when the aligner shell is fitted over the teeth, the magnets in the shell exert attraction or repulsion forces on the metal plates to move the selected teeth in accordance with a treatment protocol.

Abstract: An orthodontic bracket includes a bracket body and a ligating member. The ligating member retains an archwire in an archwire slot and includes archwire control structure including projecting portions spaced apart in a mesial-distal direction with a recessed area therebetween. The recessed area and the projecting portions overlie the archwire slot. The recessed area may include a flat or a curved surface in a mesial-distal direction. The recessed area and projecting portions may define a radius of curvature that is less than the radius of curvature of the archwire seated in the slot. The archwire contacts one or both the projecting portions resulting in a larger moment arm and better rotational control of the bracket with the force applied by the archwire.

Abstract: The reusable bite-recording kit for dental implants includes one or more first bases, each of which is removably secured in a previously installed implant. The first bases have adjustably threaded rods extending therefrom, with contact fittings disposed upon the distal ends of the rods. Two second bases are removably secured in previously installed implants opposite the first bases. The second bases have plates at their distal ends, with the plates captured in a channel of an occlusal table. The table defines an occlusal plane. The rods of the first bases are adjusted to place their contact fittings just in contact with the occlusal plane of the occlusal table of the second bases, thus establishing the occlusal plane of the first bases for the manufacture of prosthetic teeth of proper height. This precludes the imprecise fittings that can occur using non-rigid elastomer materials.
