Abstract: Various aspects are directed to dental extraction and dental extraction devices. As may be implemented in accordance with one or more embodiments herein, a dental extraction apparatus includes an engagement component that extracts teeth from patients' mouths by engaging with and applying a torque to a tooth. An input torque component translates received input torque to the engagement component. A torque controller operates with the input torque component and the engagement component to limit the applied torque, relative to input torque provided via the input torque component.

Abstract: A dental implant for supporting periodontal tissue and the supporting bone is provided. The dental implant includes an implant member for insertion into a periodontal bone socket, and an anchoring assembly. The anchoring assembly includes a fastening element and radially equidistant cylindrical members. The fastening element engages the implant member within the hollow axial cavity.

Abstract: An orthodontic appliance has a post attached to a first upper tooth, and a button with a recess attached to a second upper tooth. An elongated arm has an eye at one end through which the post is inserted to allow the elongated arm to rotate about the post, and a tip at the other end for removable insertion into the recess of the button. The length of the elongated arm is selectable to maintain a desired spacing between the first and second upper teeth (e.g., by cutting the tip of the elongated arm). An elastic extends from either the post or button to an attachment point on the patient's lower dental arch to exert a force between the patient's maxilla and mandible.

Abstract: The present invention addresses the problem of providing an orthodontic retainer with which there are no aesthetic concerns and smooth pronunciation during conversation is possible, and which is able to secure favorable fitting and can be worn for long periods. The retainer is configured so that, by being fitted so as to surround the entire dental arch (T) of the maxilla (A) or the mandible and by the inner surface being fitted, on the front and back surfaces of the entire dental arch (T), with a specified vertical width (H) that encompasses the cervical sections (T1, T2) of said teeth, a retaining force is applied on a portion of the crown (T3) of each tooth from the front and back surfaces.

Abstract: The system includes a reservoir for fluid; a droplet generator for creating a stream of fluid droplets from the fluid wherein the velocity of the stream of droplets is within a range of 20 meters per second to 200 meters per second and the size of the droplets is within a range of 5 microns to 200 microns. A nozzle or nozzles direct the stream of droplets to safely clean a selected tooth or teeth surface area. The specific momentum of effective fluid droplets within the stream of fluid droplets is important in safe and effective cleaning.

Abstract: A teeth whitening device includes a generator configured to generate a teeth whitening fluid that whitens teeth and humidified gas, a mouthpiece configured to supply the teeth whitening fluid and the humidified gas, and a coupling part that couples the generator and the mouthpiece with each other.
