Abstract:
In various embodiments, the present invention provides a tooth whitening composition comprising a peroxide composite and an orally acceptable carrier. The peroxide composite comprises a peroxide compound and a porous cross-linked polymer, preferably in the form of a microporous particulate. The peroxide compound can be sorbed onto the porous crosslinked polymer. The porous cross-linked polymer may comprise a polymerized polyunsaturated monomer selected from polyacrylates, polymethacrylates, polyitaconates, and mixtures thereof. The carrier can be non-aqueous, and can comprise a film forming material. Methods are also provided for whitening a tooth surface with the tooth whitening compositions.
Abstract:
A method for whitening a dental surface comprises nonsimultaneously applying a whitening composition to the surface, the whitening composition comprising at least one orally acceptable peroxy compound, and directing a volume of up to about 2.5 ml of an atomized activating composition on to the surface, wherein the activating composition comprises, in the volume so directed, a peroxy compound activating effective amount of at least one orally acceptable basifying agent, and wherein applying the whitening composition and directing the activating composition are separated by an interval not greater than a peroxy compound activating effective interval. The atomized composition can be directed on to the dental surface before or after application of the whitening composition.
Abstract:
An implantation apparatus for preparing adjacent vertebral bodies to receive an intervertebral implant including a plurality of keels. The implantation apparatus includes an elongated handle portion, and a template portion carried at a distal end of the handle portion substantially perpendicularly to the handle portion. The template portion defines a plurality of open channels corresponding in position and shape of the plurality of keels. Each channel is positioned and shaped for preparing a vertebral opening to receive a corresponding keel.
Abstract:
Dual-component tooth-whitening systems are disclosed comprising a peroxygen whitening agent in the first component and a transition metal catalyst along with an alkaline compound in the second component. Also disclosed are tooth-whitening methods based upon the systems.

The present disclosure is directed towards conducting a search for content and results using a user interface. A number of graphical objects (715) and filters are displayed where a search query is generated in response to a user gesture (730) that selects a graphical object and filter. The filters shown can change depending on various factors that impact what filters are selected from a group of filters (720).
Abstract:
A system for cutting a bone at a desired location may include an image guided drill cylinder configured to receive either a drill bit to create a bore at a target location on the bone or a pin for insertion into the target location, and a cutting block having a plurality of adjustable guides, each defining a cutting path to guide a cutting instrument, a mounting location configured to attach to the bone at the target location, and a plurality of adjustors for adjusting the position of the guides relative to the target location. The system may further include a tracking instrument for providing image guidance of the adjustments to the positions of the guides.
Abstract:
A method of conducting a survey by a wireless device having a memory circuit and a display screen, the wireless device being capable of wireless communication with a server during a connection period, is provided. The method involves: downloading from the server during the connection period a metadata variable; displaying on the display screen of the wireless device presentation information associated with the metadata variable; receiving user input in response to the presentation information; after receiving the user input, allocating memory of the memory circuit for storing the user input in association with the metadata variable; and storing the user input in the memory in association with the metadata variable. A system for conducting a survey by a wireless device includes a server and a plurality of the wireless devices.
Abstract:
A stable, nonaqueous liquid tooth whitening composition comprised of an anhydrous peroxide compound dispersed in an orally acceptable hydrophobic organic material such as a silicone based pressure sensitive polymer which composition when applied topically to tooth surfaces forms an adherent layer containing the peroxide compound which peroxide compound is thereafter is released from the layer to effect tooth whitening.
Abstract:
A joint distraction device for facilitating joint arthroscopy disclosed. In the first embodiment of the invention, the distractor disclosed is a series of fluidly fillable spheroid members to form a toroid. The joint distractor is placed between articular cartilage surfaces and filled to hold the joint surfaces apart. In a second embodiment of the invention, a string of spheroidal members is disclosed. The spheroidal members have varying diameters and are used to separate the articular surfaces of a joint.
