  • Patent number: 11638632
    Abstract: The present invention provides a dental implant including: a fixture and an abutment including a coupling leg, and the fixture and the abutment are elastically coupled with each other, the dental implant including: a fixture axial hole inner inclined surface in which an inner diameter of an axial hole is gradually and downwardly reduced from a predetermined position of an inner inclined surface of the fixture; a first coupling part formed with a coupling hole at a predetermined position of the fixture; and a first associated coupling part formed with a coupling protrusion complementarily coupled with the first coupling part, wherein when the first associated coupling part is separated from the first coupling part by rotating the abutment, the coupling protrusion upwardly pushes the abutment from the fixture by elastic repulsion with the axial hole inner inclined surface of the fixture, thus the abutment becomes separated from the fixture.

  • Patent number: 11628042
    Abstract: An endodontic instrument of this disclosure has less torque strength but greater flexibility and enlarged chip space compared to the prior art. In embodiments. only two flutes are spiraled about the instrument's length L to form two non-landed cutting edges between D2 and D16, the cutting edges merging to form a land at about D1. The tip end is rounded. The helical angle ? increases from the handle end toward the tip end, a number of spirals per unit length being at least two times greater toward the tip end than toward the handle end, a cross-section of the length L consisting of two convex portions intersecting at each cutting edge or a wave-shape having one concave portion and one convex portion intersecting at each cutting edge, the cross-section occupying less total area than would a same size endodontic instrument having a triangular cross-section and providing greater chip space.

  • Patent number: 11576752
    Abstract: Methods and apparatus for producing controlled tooth-moving forces are provided. An orthodontic appliance includes one or more occlusal surface features that modify bite forces between opposing teeth during intercuspation to aid in realignment of the teeth. The interception bite forces can be applied between appliance shells on opposing arches, or between an appliance shell and an opposing tooth. These modified bite forces can be used to supply or augment tooth-moving forces, and the tooth moving forces can produce moments to urge rotational movement of a tooth. Also described herein are orthodontic appliances having an occlusal outer surface contours that are distinct from the occlusal inner surface contour within the dental appliance and may be configured to selectively intercuspate.

  • Patent number: 11564778
    Abstract: Provided herein are exemplary orthodontic elastic attachments that are customized to fit within the cutout windows of dental aligners, thus improving adhesion and minimizing inadvertent detachment from the tooth surface. The unique base pads are designed to have a shape that complements the present shape of the cutout windows like a puzzle piece. To improve adhesion to the tooth surface, the base pad may have its surface area maximized within the cutout windows. Also for improved adhesion, the base pad may be contoured to the dental anatomy of the tooth at the gumline for an intimate fit. Further exemplary embodiments may include the base pad having beveled edges to permit the aligner to slide over the base pad if it is adhered slightly off-center.
