An orthodontic treatment device includes: a receiving element fastenable in the jaw of a patient for receiving at least one wire arch portion (; and a securing element for securing the orthodontic wire arch in the receiving element. The receiving element has, a first or gingival receiving pocket for receiving a first or gingival wire arch portion and a second or occlusal receiving pocket for receiving a second or occlusal wire arch portion which together form a C-shaped receiving opening for the securing element an inserted state, the securing element The wire arch can be held in the gingival receiving pocket and placed on the bent inner surface of the gingival receiving pocket. The securing element has a first or gingival contact surface (adapted to a first or gingival wire arch portion for securing the wire arch in the gingival receiving pocket.

Implant placement assist (IPA) systems and methods for creating a dental implant chamber in an alveolar ridge of a jawbone of a patient, the alveolar ridge being atrophied and needing augmentation before a dental implant can be placed. The IPA system includes a non-osseous spacer and an anchor to maintain a position of the non-osseous spacer within a bone graft cavity of a patient. Bone graft material can be positioned around the non-osseous spacer and the anchor and maintained within the bone graft cavity during healing, where bone is regenerated within the bone graft cavity. After healing, the non-osseous spacer can be removed, thereby forming the dental implant chamber that is immediately ready to receive a dental implant.

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.

An orthodontic appliance shaped to receive teeth. The orthodontic appliance can be constructed from a laminate structure with a outer transparent layer and an inner translucent layer. The translucent layer can scatter light to decrease a relative degree or perceived gloss to the human eye, and hence provide a more natural appearance to the orthodontic appliance.

A graphical user interface (“GUI”) is generated on the display, the GUI has a graphical depiction that simulates a translucence level of an oral appliance. The graphical depiction of the translucence level is adjustable based on a user input. A value based on the user selected translucence level is sent to an external device for determination of manufacturing parameters for the oral appliance.

A device for mandibular advancement, including a tube and a telescopic rod associated with the tube, in which the tube and the telescopic rod can be associated to the teeth of the upper and lower arches, in which the telescopic rod includes a threaded pin which engages a female thread of a hollow element slidably positioned in said tube, and the hollow element includes a maneuvering portion external to the tube; the device includes a friction element, arranged between the inner walls of the maneuvering portion and the thread of the pin and having an outer surface which is complementary to the inner walls of said maneuvering portion and a threaded internal cavity which copies the thread of the pin.

The present invention discloses a teeth whitening product containing a piezoelectric material. The present invention uses a piezoelectric material with piezoelectric effect as a whitening ingredient of the teeth whitening product. The teeth whitening product is applied to teeth and exerts pressure on the tooth surface to activate piezoelectric properties of the piezoelectric material. Thus, abundant reactive species are produced to degrade teeth stains, achieving teeth whitening. The teeth whitening product of the invention is safe and nontoxic; a teeth whitening method is easy to operate, does not cause damage to oral soft tissues, enamel layers on the tooth surface, and the tooth structure, and obtains a long-lasting teeth whitening effect.

A method of treating teeth and gums within an oral cavity including treating the accessible surfaces and hard-to-reach surfaces of the teeth and gums. The method includes providing an oral care composition including a therapeutic amount of sodium bicarbonate, providing a tool that generates hydrodynamic power, and applying the oral care composition to the accessible surfaces and the hard-to-reach surfaces of the teeth and gums and generating hydrodynamic power within the oral cavity. The combination of the oral care composition and the hydrodynamic power more effectively removes biofilm from the accessible surfaces and the hard-to-reach surfaces of the teeth and gums.

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.
