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.

Abstract: An orthodontic bracket apparatus and method for treating a malocclusion includes a bracket base having an angulated posterior facing surface and which is matingly and releasably positioned adjacent to an anterior facing surface of a patient's tooth; a multiplicity of bracket bodies releasably and adjustably engageable with the bracket base; and an arch wire simultaneously engageable within an arch wire slot defined in each of the bracket bodies to exert first, second and third order movements to the maloccluded tooth; and wherein the bracket base remains affixed to the patient's tooth throughout the multiple step orthodontic treatment regimen selected by the treating clinician.

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.

Abstract: Provided is a guide pin for dental implant surgery, providing guidance so that a practitioner easily determines a location and angle of an alveolar bone of a patient when forming an implant hole in the alveolar bone to place an implant in the alveolar bone. By using the guide pin for dental implant surgery according to the inventive concept, a practitioner may perform the surgery by determining an accurate location and shape of the alveolar bone of the patient when drilling an implant hole in the alveolar bone, and thus, the success rate of the implant surgery may be increased.
