Abstract: The invention provides a dental implant system with a surface gradient microporous structure and a preparation method thereof. The dental implant system includes a non-threaded micro-cone cylindrical dental implant and an abutment, wherein the dental implant includes a microporous layer with a bionic bone trabecular structure and a base with extremely high density and mechanical strength. The dental implant system of the invention has both the precision of the internal structure and the bionic characteristics of the surface structure, which effectively improves the long-term stability after implantation, reduces the complexity of the processing process of the dental implant system, and can realize personalized and batch production.

Abstract: 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.

Abstract: Orthodontic arch wires with specific shapes and bends designed to encourage expansion of the posterior teeth while preventing the flaring of anterior teeth during the alignment phase. The arch wires divide the dentition into sections and treat each section differently so as to minimize undesirable effects during the alignment process. While the arch wires of the present invention are used to improve mechanics with non-extraction, they can also be used in extraction cases to avoid round tripping and some iatrogenic side effects that can occur by engaging all the teeth at the same time. The arch wires of the present invention can be preformed or customized to each case. The arch wires of the present invention are generally of two types referred to as sectional (S-RA) wires and consolidation (C-RA) wires.

Abstract: 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.

Abstract: 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.
