Abstract: Apparatuses and methods for monitoring the performance of an orthodontic appliance for repositioning a patient's teeth. An orthodontic appliance may include a plurality of teeth receiving cavities shaped to reposition the patient's teeth from an initial arrangement towards a target arrangement, and one or more sensors configured to determine tooth movement (based on position and/or orientation) and/or forces applied to the teeth. The sensor may be distributed between attachments and aligners that mate with the attachments.

Abstract: A micro pump vessel has an outer vessel on one side of which a button is formed and an outer vessel lid which is hinge-coupled to one side of the outer vessel to be opened and closed. In the vessel, a first and a second pistons are installed on an upper surface of cosmetic contents, and thus, when the cosmetic contents are pumped and used by the operation of a micro pump, the first and the second pistons lower to exhaust all the cosmetic contents so as not to discard the remaining cosmetic contents.

Abstract: Methods and apparatuses for monitoring either or both the performance of an orthodontic appliance for repositioning a patient's teeth and/or the user compliance in wearing the appliance using a biosensor. The apparatuses described herein may include one or more sensors, including biosensors, electrical sensors, or both, configured to generate sensor data related to user compliance and/or repositioning of the patient's teeth by an orthodontic appliance.

Abstract: A system for removing aerosol contaminants from the air in a room is disclosed. The system comprises a vacuum inlet coupled to a vacuum system and operable to draw air from nearby into the vacuum system, filter out aerosol contaminants present in the air, and return the filtered air back into the room. The system includes airways internal to a dental chair, through which air may be drawn and filtered. The system may be used near a patient during a dental or medical procedure to remove aerosol and splatter potentially containing such contaminants as COVID-19 and other infectious diseases.

Abstract: An apparatus for tooth stain removal is presented. The invention comprises a powered device with a chisel tip at its distal end, a body at its proximal end and an electric motor housed within the body for driving the chisel tip. The chisel tip has a proximal end removably coupled to the body and an exposed distal end along a generally longitudinal axis. The chisel tip comprises a pointed end on a first side for cleaning area between teeth and a broad cleaning surface on a second side for cleaning the main surface of each tooth. The chisel tip operates in a reciprocating motion driven by the electric motor. The reciprocating motion repeatedly moves the chisel tip in a back and forth direction by a finite displacement along the chisel tip's longitudinal axis.

Abstract: Embodiments of the present invention provide devices (tags), systems, and methods to determine structural integrity and other states of orthodontic-elements, such as orthodontic-brackets, orthodontic-archwires, orthodontic-expanders, orthodontic-elastic-bands, and orthodontic-power-chains, to name a few, in a non-invasive and contactless way, with respect to monitoring; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized backscatter-tags with sensors are implanted in or attached to such orthodontic-elements. Such arrangements may permit monitoring of forces acting on teeth by various orthodontic-elements. Using backscatter imaging technology, the structural integrity and other states of the orthodontic-elements may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like.
