  • Patent number: 10245128
    Abstract: A damping dental post key configured to implant a dental root post for restoration of a tooth is described. The dental post key includes a body for handling and a post carrier having a key shape with respect to a head portion of the dental root post. During implantation of the dental post, rotation of the body compresses a set of springs in contact with the post carrier reducing a reaction force to a tooth root. In this way a limited force will be applied and a root fracture can be prevented. Further, the dental post key can be configured to have a fixed movement in a counterclockwise direction to remove the dental post and a free quarter-cycle movement with effort in a clockwise direction.

  • Patent number: 9949809
    Abstract: Non-customized dental treatment trays used to provide a desired treatment are formed from elastomeric silicone or silicone-like material. They may be molded from a two-part liquid silicone composition or a silicone-like TPE material (e.g., preferably SEBS and/or VERSAFLEX™ thermoplastic elastomer). The dental treatment trays possess high adaptability, flexibility, softness, and elastic elongation while also exhibiting resiliency in order to readily conform to the ridges, depressions and contours of a person's teeth during use. The trays possess a greater ability to adhere to a person's teeth compared to non-elastomeric thermoplastic materials. Due to their high adaptability and conformability, the non-customized dental trays behave like a semi-custom dental tray when placed over conformed to a person's teeth, particularly when used in combination with a sticky, viscous treatment composition.
