Abstract: A hair styling device for styling curly or wavy hair. The hair styling device includes a body and a plurality of tines extending from a proximate end of the body, wherein each of the plurality of tines have a same length as measured from a proximal end to an opposing distal end of a tine. The tines are rigid and non-flexible to facilitate the manipulation and styling of curly hair. In some embodiments, the tines are angled such that the proximal end of the tine extends from a first side of the body and the distal end of the tine is disposed on a second side of the body, wherein the first side and second side are opposite one another. In other embodiments, the tines include an arcuate configuration. The configuration of the tines allows for various manipulation of hair to provide differently styled curls or wavy features.

Abstract: Techniques are described for automating the design of dental restoration appliances using neural networks. An example computing device receives transform information associated with a current dental anatomy of a dental restoration patient, provides the transform information associated with the current dental anatomy of the dental restoration patient as input to a neural network trained with transform information indicating placement of a dental appliance component with respect to one or more teeth of corresponding dental anatomies, the dental appliance being used for dental restoration treatment for the one or more teeth, and executes the neural network using the input to produce placement information for the dental appliance component with respect to the current dental anatomy of the dental restoration patient.

Abstract: A system and method for creating a model of a patient's mandible and any teeth supported from the mandible and manipulating the mandible relative to anatomical features of the patient's maxilla. The system uses markers positioned on the mandible and on the maxilla to create a functional mandibular axis that approximates an axis through the condyles of the patient. The functional mandibular axis and geometric and anatomical information about the patient's upper and lower jaw are then used to create prostheses for the patient. The system is also used for making corrections to the prosthesis.

Abstract: Methods, systems, and products monitor a person's regimen for medicinal and dietary restrictions. When the person's regimen requires a liquid medication or supplement, an oral instrument is commanded to dispense a dosage of fluid. The oral instrument stores a reservoir of the fluid. If the oral instrument is a spoon, for example, the spoon may automatically dispense cough syrup or other medicine. A toothbrush, likewise, may automatically dispense mouthwash. A sensor may confirm presence of the oral instrument in the person's mouth, thus ensuring the dosage of fluid is ingested.

Abstract: An endodontic file measuring device includes a housing with an upper opening for receiving the file within a file channel in the housing. A movable base is disposed in the file channel and a plurality of sensors are disposed along the file channel. When a tip of the endodontic file is positioned on the movable base, the sensors can detect a presence of the file within the channel and measure a length of the file in the channel. A slider protrudes from the front wall of the housing and is connected to the base by a connecting rod. The slider can be manipulated by the user to lower or elevate the file within the base. A display on an outer surface of the housing displays the length of the file present in the file channel.

Abstract: A tooth implant system has an upper abutment, a lower abutment, a crown, and an elastic member securely placed between the upper abutment and the lower abutment providing softer and elastic, yet resilient, cushion between the upper abutment and the lower abutment. To better affix the elastic member within the tooth implant system, a ring lock may be used, securely placed in a ring-lock groove located on the lower abutment section. An insertion of a screw deeper into the lower abutment receptacle pushes the ring lock-groove and the ring lock outwardly to force the elastic member against an inner chamber wall of the upper abutment and into the abutment groove to better securely affix the elastic member.

Abstract: Apparatuses (e.g., systems, devices, etc.) and method for scanning both a subject's face as well as the subject's intra oral cavity to provide two-dimensional (2D) and/or three dimensional (3D) data that may be subsequently used in prosthodontic and orthodontic procedures, including smile planning (e.g., designing or modifying a subject's overall smile or facial aesthetics).

Abstract: A personal care implement has a handle including an elongate body having opposed first and second sides extending longitudinally between opposed proximal and distal ends, and first bristles attached fixedly to the elongate body. The first bristles form a scrub brush extending longitudinally of the elongate body between the proximal and distal ends, transversely of the elongate body between the first and second, and outward from the elongate body to a scrub-brushing extremity. An elongate member extends outward longitudinally from the distal end to a toothbrush head assembly. The toothbrush head assembly is of a first size to facilitate reception of the toothbrush head assembly in a mouth of a user for toothbrushing. The handle is of a second size larger than the first size to facilitate grasping and holding the handle by one hand of the user.

Advantageously, the devices are anchorable for directional release and attachment to a surface. The crown may be hingedly positionable with respect to a vented suction base anchorable to a surface. Further provided for are methods of use of devices in the application of nail polish or in crafting, such as in vinyl weeding.

Abstract: Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

Abstract: A device for generating singlet oxygen is provided. The device has a sensitizer that converts triplet oxygen to single oxygen upon exposure to light. The device is configured to keep the sensitizer from contacting external fluids.

Abstract: Disclosed is a multi-functional visual electric toothbrush, including a main unit, an oral viewer, an interdental cleaning appliance and an electric toothbrush head. The oral viewer is connected to the main unit, the interdental cleaning appliance is connected to the front end of the oral viewer, and the electric toothbrush head is connected to a toothbrush driving mechanism. A circuit system and a control system of the main unit can not only transfer the energy of a power supply to the toothbrush driving mechanism, so as to drive the electric toothbrush head to work for large-area oral cleaning, but also connect a lighting system, an observation system and a switch of the oral viewer to control the oral viewer to work. The interdental cleaning appliance may be used cooperatively with the oral viewer to perform targeted cleaning on difficult-to-clean food debris in an oral cavity.
