The present invention relates to a contra-angle dental handpiece attachment (100) for a device (200) for driving an endodontic file (1000) and for operating a remote pump (700).

Antimicrobial polymer composite materials are disclosed that are suitable for making oral devices used in dental applications, such as denture bases. Acrylic resin composite materials comprising antimicrobial polymers and antimicrobial fillers provide reduction in common oral microorganisms after long-term aging, with reduced release rate of antimicrobial agents from the composite material. Antimicrobial polymers are prepared from compositions comprising acrylate and/or methacrylate monomers and polymerizable quaternary ammonium silicon-containing compounds.

An approach for attaching a superstructure, such as a crown, to an abutment by an approach that includes causing thermoplastic material to become flowable due to mechanical energy input, and to flow relative to an attachment structure to secure the superstructure and crown together.

A subgingival deep dental implant oral surgical retraction article comprises a polymeric foam sponge that is autoclavable at 250 F. and has a porosity not less than a porosity of polyurethane and is configured in size and shape for retracting a gingival flap at an incision site during a subgingival implant surgery.

Devices configured for insertion into an oral cavity of a subject for delivery of an agent for a time period are described. The devices are comprised of at least two polymer shells that nest or stack to create a space or gap therebetween. The agent is placed in the gap and is released in a controlled fashion to deliver agent for the time period. Kits comprised of a device and optionally a refill of the agent are also described.

This disclosure provides polymeric materials comprising polymer crystals, methods and resins for making the same, and objects and appliances made from said polymeric materials. Polymeric materials having polymer crystals provide favorable properties, such as enhanced durability and rigidity. This disclosure also provides polymeric materials comprising a crystalline phase comprising at least one polymer crystal, as well as an amorphous phase comprising at least one amorphous polymer. The crystalline phase can confer rigidity to the polymeric material, while the amorphous phase can confer elasticity and flexibility.

The invention relates to a glazing composition suitable for glazing the surface a dental zirconia article. The glazing composition comprises a liquid, glass particles, and hydrophilic silica nano-particles. The invention also relates to a process for sintering a porous dental zirconia article with a glazing composition on its surface.

A dental dam clamp and method comprising an aperture frame, a first opposing jaw, and a second opposing jaw is disclosed. The first opposing jaw is coupled to a first opposing end of the aperture frame, and the second opposing jaw coupled to a second opposing end of the aperture frame. The first opposing jaw and the second opposing jaw are biased toward a rest state by the aperture frame. The external surface of the aperture frame comprises at least one notch, and the internal surface of the aperture frame defines a treatment aperture. The aperture frame may be substantially parallel with both the first opposing jaw and the second opposing jaw.

A brace that includes at least one chin rest for stabilizing a patient's jaw in a fixed relative position. More specifically, the at least one chin rest is itself supported in its fixed position using additional mechanisms such as a chest plate or one or more arms that can be attached to a dental or oral surgical chair. The brace is used to stabilize a patient's jaw when the patient's jaw is supported by the at least one chin rest.

A dental carrier comprises a thermoplastic carrier. The thermoplastic carrier has a pattern structure. After heating the thermoplastic carrier, the thermoplastic carrier is provided with a user to be impressed by teeth or alveolar ridge for forming teeth or alveolar ridge model of the user. Compared to the prior art, the dental carrier of the present invention can provide the dental medicament contained in the pattern structure to be precisely applied and hold onto the treatment area and the medicament can be evenly coated on the teeth, root, or periodontal tissue for the treatment of teeth. When the dental carrier is not used to carry medicament, the pattern structure can improve the mechanical strength and fitness of the dental carrier to be used as a biteplate, orthodontic retainer, periodontal dressing for treatment or protection or mouth guard in sports.
