An apparatus including a transducer head and a motion transfer member, and a method for rupturing connective tissues that attach a tooth to an alveolar bone socket are provided. The transducer head generates and transfers vibrational and tapping movements to the motion transfer member. The motion transfer member, extending from the transducer head via a neck of a transducer assembly, includes a ball projection and a flexible member. The ball projection connected to a distal end of the neck transfers the generated vibrational and tapping movements received from the transducer head to the tooth. The flexible member housing and surrounding the ball projection contacts a tooth surface and generally conforms to a shape of the tooth to distribute the generated vibrational and tapping movements uniformly in multiple directions on the tooth to rupture the connective tissues and allow the tooth to be loosened and removed from the alveolar bone socket.

An apparatus including a bite frame and a bite shaped member is provided. The bite frame includes one or more arcuate frame elements defining an opening for accommodating a mesh element or the bite shaped member that receives a bite registration material for registering a bite impression. The bite shaped member has a geometrical body structure, upper and lower channels of configurable shapes, and upper and lower windows. The upper and lower windows are separated by a space for receiving and allowing flow of the bite registration material to register a vertical distance between the upper and lower jaws. An image processing system operably connected to the apparatus determines the three-dimensional relation between the upper and lower jaws with reference to temporomandibular joints using panoramic images of the upper and lower jaws, reference points provided by radio-opaque markers, three-dimensional scanned images of the bite impression, and three-dimensional head surface images.

An amphibious protection apparatus includes wall members that define an occupancy space for accommodating one or more users, and an access region for providing access to the occupancy space. Each wall member is foldably and detachably connected to each other. Each wall member includes a thick outer layer defining an outer enclosed space and an inner inflatable member having an inner enclosed space. The outer enclosed space accommodates the inner inflatable member. A fluid injected into the inner enclosed space inflates the inner inflatable member, thereby inflating each detachably connected wall member to form a buoyant enclosure that bounces on land and floats on water. The buoyant enclosure protects the accommodated users from impacts from different directions on land and water. The amphibious protection apparatus also includes an access port having an arrangement of lenses that enables magnification and viewing of objects present in an external environment.

A dental floss and brush apparatus includes a handle, an arcuate head member including a first arcuate arm and a second arcuate arm, a flossing assembly, and an interdental cleaning member including a flossing element and brush bristles. The flossing assembly includes an elongate channel to accommodate and allow traversal of the flossing element, and a spool member to wind and rotate the flossing element for the traversal of the flossing element through the elongate channel. The flossing element supported between two tubular members dislodges interdental substances in an oral cavity. The brush bristles create a diverging extension arm of a wide dimension towards the first arcuate arm to brush away the dislodged interdental substances from a buccal side of teeth, and another diverging extension arm of a narrow dimension towards the second arcuate arm to brush away the dislodged interdental substances from a lingual side of the teeth.

A precision configuration system includes a plier device having clasp members, a heat transfer clamp member, a bending force transducer, and a temperature controller. One clasp member has a single jaw tooth that contacts and heats a component, for example, a wire positioned by a component holder and accommodated within a receptacle defined between double jaw teeth of the other clasp member. The heat transfer clamp member includes a heating coil that generates and transfers heat to the single jaw tooth. The bending force transducer controls magnitude and direction of bending forces applied by the plier device to precision bend and reshape the component at one or more bending points on the component based on force commands received from a component configuration computer system. The temperature controller controls the generation and transfer of heat to the single jaw tooth to facilitate temperature controlled, precision bending and reshaping of the component.
