A dental appliance is described, the dental appliance including a polymeric substrate with a plurality of cavities for receiving one or more teeth, an arrangement of engineered microstructures on the substrate wherein the engineered microstructures include a therapeutic agent. The microstructures may be three-dimensionally engineered on a polymeric film disposed on a major surface of the polymeric substrate, wherein the microstructures extend outwards from the surface. The microstructures also comprise a compound releasable from the three-dimensionally engineered microstructures over a predetermined patient wear time.

This application relates to oral hygiene and/teeth cleaning devices and associated methods. The devices can be configured to have a shape that allows all or substantially all of a user's teeth to be cleaned at once. In some embodiments, the devices are configured to be useable, for example, without access to water or a bathroom. The devices can be used to freshen up and clean the user's mouth on-the-go. In some embodiments, the devices are disposable.

This disclosure relates to oral care mouthpieces and methods of forming oral care mouthpieces. A disclosed oral care mouthpiece includes a base shaped to a dental arch. The base elastically deforms in response to pressure variations in the mouthpiece. The mouthpiece also includes a set of one or more supports attached to the base and placed to allow the base to elastically deform in response to the pressure variations in the mouthpiece. The mouthpiece also includes a set of oral care elements attached to the set of one or more supports and placed to transmit pressure to the dental arch when the base elastically deforms in response to the pressure variations in the mouthpiece.

Systems and methods are generally described for an oral hygiene device. The oral hygiene device may include a handle portion and a head portion coupled to the handle portion and including a pick head interface. A pick head may be removably coupled to the pick head interface. The pick head may include a pointed pick member. An image capture device may be disposed in the head portion. The image capture device may be effective to capture image data representing images of an area proximal to a tip of the pointed pick member. A vibration element may be coupled to the pick head interface. The vibration element may be effective to vibrate the pick head.

Methods, systems, apparatuses and devices for implantation in a soft-tissue biological environment that include a primary layer for containing a filler substance, an interface and a secondary layer, including embodiments where the secondary layer an ePTFE layer, the primary layer is a silicone layer, the interface is mechanical or adhesive and the filler substance can include particulates and lattices.

An oral care device for placement in the oral cavity. The oral care device may include a support component, a piezoelectric component, and/or a therapeutic element. The support component is configured for placement between one or more maxillary teeth and one or more mandibular teeth. The piezoelectric element is configured to generate an electrical current from relative movement of the maxillary teeth and the mandibular teeth. The therapeutic element is configured to release a therapeutic composition into the oral cavity at least in part in response to receiving the electrical signal. The device may include the piezoelectric component, the therapeutic element, or both.

An electrical discharge irrigation includes a power source to produce a first voltage, a circuit coupled to the power source to convert the first voltage to a second voltage, a discharge capacitor to receive the second voltage from the circuit, a transistor and/or a controlled rectifier coupled to the discharge capacitor to receive the second voltage, and an output tip. This tip is coupled to a transistor and/or a controlled rectifier and includes a first end, a second end, a longitudinal axis extending between them, an electrode located in an interior space of the tip to receive an electrical charge from the a transistor and/or a controlled rectifier and to release an electric discharge, and a ground return. The ground return is an outside surface of the tip. A space between the electrode and the ground return holds a conductive medium in contact with the electrode and the ground return.

The invention features a pharmaceutical suspension containing drug particles, a drug delivery device anchored in the mouth for continuously administering the pharmaceutical suspension, and methods of their use.

A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

A cartridge for delivery of a material therefrom which has a corrugated portion to allow for bending/extending to be applied to the device from which a material to be deposited can be dispensed. The bendability and extendibility allow for greater efficiency in use and application of the material into cavities, pockets, and/or crevices where one needs to deposit the material.
