A wire cutter suitable for creating a cavity in cancellous bone includes a restrainer and a cutting wire, wherein a portion of the cutting wire will protrude from a slot formed on the restrainer to the outside of the restrainer and inside a bone, when the cutting wire is advanced in a tunnel formed in the restrainer and toward a closed end of the tunnel.

Device and method for cutting into a cancellous bone

The present invention provides a delivery tool and a method for bone grafting on a bone surface via a minimally invasive approach, wherein a structure having a layer of hardened paste and particles under the layer is formed by using the delivery tool. The layer helps to keep particles on the bone surface.

In order to deliver porous particulate material into a cavity via a thin tube without substantially crushing the porous particulate material, a two-step process and an apparatus for use therein are provided. The two-step process involves inserting a first rod into the thin tube to push the porous particulate material therein; removing the first rod from the tube; and (a) inserting a second rod into the thin tube, or (b) joining a second rod with the first rod, and inserting the joined first rod and second rod, to push the porous particulate material which remains in the thin tube. In (a), the first rod has a cross sectional area significantly smaller than that of the thin tube, and the second rod has a cross sectional area which is about equal to that of the thin tube. In (b), each of the first rod and the second rod has a cross sectional area about half of the thin tube.

Particulate material delivery system and method

A resin-retained denture bridge having an improved bonding between a false tooth or teeth of the bridge and a retainer wire of the bridge is provided in the present invention, wherein a coupling recess is formed on a lingual side of the false tooth and a protrusion or an omega-shaped bend is formed on the retainer wire. The protrusion or omega-shaped bend is received in the coupling recess of the false tooth after or prior to a resin being filled in the coupling recess, which is then cured to form a secure engagement, so that the false tooth is bonded to the retainer with the end portions of the retainer wire extending laterally from the false tooth.

Reinforced resin-retained bridge

An dental implant has a substantially cylindrical hollow base member; an abutment; an implant-abutment junction (IAJ) portion at one end of the base member to retain the abutment to the base member, so that the abutment is able to move within a predetermined distance alone an axial direction of the base member, and a first cushion adapted to be mounted between the abutment and the base member for providing a resistance force when the abutment is pressed to move relatively toward the base member and providing a bouncing back force when the abutment is released from the pressing.

Dental implant with cushion

An dental implant has a substantially cylindrical solid base member; an abutment; an implant-abutment junction (IAJ) portion at one end of the base member to retain the abutment to the base member, so that the abutment is able to move within a predetermined distance in an axial direction of the base member, a first cushion adapted to be mounted between the abutment and the base member, and a second cushion, preferably an elastomer, which is sandwiched between the IAJ portion and the abutment, wherein the first and second cushion are able to provide a resistance force when the abutment is pressed to move relatively toward the base member and providing a bouncing back force when the abutment is released from the pressing.

Double-cushioned dental implant

The present invention discloses a method for detecting whether cells are infected with human papillomavirus (HPV), and the method includes: (a) capturing a contour of a cell of a cell image, wherein the contour has a contour pixel thereon; (b) identifying a tangent of the contour pixel on the contour to define in relation to the tangent a first side and a second side opposite to the first side, wherein the first side indicates the intracellular region of the cell and the second side indicates the extracellular region of the cell; (c) calculating an optical parameter average of the plurality of pixels on both of the first side and the second side; and (d) determining whether the cell is infected with HPV based on whether the optical parameter average on the first side is smaller than that on the second side.
