6 results about "Dental implant" patented technology

Screw (100), surgical driver (400), kit and torque key (500) to fix a prosthesis (200) on a dental implant (300). The screw (100) has a pin comprising fixing means arranged to fix the screw (100) in the implant (300) in a detachable way; a head, to house the prosthesis (200). The head comprises a protruding area which is mostly spherical and has curved-concave meridional sunken areas (110) to receive a grip (410, 510) of a handling tool (400, 500) for the screw (100); with a latitude between ±80°, with respect to the equator (E) of the head. The surgical driver (400) has a work part comprising fastening means with a shape which combines with the shape of the head of the screw (100). The kit comprises the surgical driver (400), the screw (100) and a protective cap (450). The torque key (500) has a similar configuration to that of the surgical driver (400).

The invention belongs to the field of dental implants and in particular relates to a dental implant. The dental implant is cylindrical, and comprises a neck and a body, wherein a micro thread is formed in the periphery of the neck upwards; an external thread is formed in the periphery of the body upwards; a cavity convenient for locking is formed inside the dental implant; and a cross lock is arranged in the cavity. The dental implant disclosed by the invention can form good synosteosis with bone tissues.

The invention discloses a dental implant containing a polyether-ether-ketone interlayer and a manufacturing method thereof. The dental implant comprises an outer base pile, an inner base pile and thepolyether-ether-ketone interlayer, wherein the outer base pile and the inner base pile are both standard revolved bodies; and a blind hole is formed in the outer base pile, the inner base pile comprises a cylindrical table and a connection rod perpendicular to the end face of the cylindrical table, the polyether-ether-ketone interlayer is fixedly arranged in the blind hole and provided with an inner thread fit with the connection rod, and the inner base pile is in threaded connection with the polyether-ether-ketone interlayer through the connection rod. The dental implant containing the polyether-ether-ketone interlayer reduces the whole elasticity modulus of the dental implant by adding the polyether-ether-ketone interlayer. The damaged dental implant can be conveniently dismantled and replaced by means of multi-layer structural design, and damage is reduced as well, especially when a central screw is always out of work. Meanwhile, the multi-layer structural design is beneficial for recycling and reusing of intact parts. The manufacturing method is easy and simple to operate, and the product cost is reduced.

The invention discloses a dental implant structure, an assembly method thereof and a dental implant system. The dental implant system comprises the dental implant structure, wherein the dental implantstructure comprises an implant, a connecting piece and an abutment, a mounting groove is formed in the implant, the connecting piece comprises a connecting nut and an elastic piece which are arrangedin the mounting groove in sequence, a connecting screw rod in threaded fit with the connecting nut is formed at one end of the abutment, a first limiting part and a second limiting part which are matched with each other are arranged on the opposite sides of the implant and the abutment respectively, and the dental implant structure is assembled by matching two arc-shaped gaskets which are encircled into a ring. According to the invention, the connecting piece is arranged in the mounting groove of the implant, and the connecting piece enables the screwed abutment to have a movable gap along the axial direction through the cooperation of the slidable connecting nut and the elastic piece, so that the first limiting part on the implant is matched with the second limiting part on the abutmentto limit the rotation of the implant relative to the abutment.

The invention discloses a shell rotary-type clamping needle fixing dental implant structure and a use method, the shell rotary-type clamping needle fixing dental implant structure is used for alveolarbone, and the shell rotary-type clamping needle fixing dental implant structure comprises an implanting rod with an inserting hole formed along the axial direction; a inserting rod to be inserted into the inserting hole; a shell to be connected to the implanting rod in a sleeved mode and in threaded connection with the implanting rod; two clamping needles to be connected to the implanting rod through a second elastic piece, the two clamping needles are oppositely arranged, notches are formed in the opposite ends of the two clamping needles, and the second elastic piece is used for driving theclamping needles to move in the axis direction of the implanting rod; and the shell is used for driving the inserting rod to be inserted into the notches to drive the clamping needles to protrude from the peripheral wall of the shell. The shell is arranged for driving the clamping needles to be inserted into the alveolar bone, so that the dental implant structure is convenient to operate and use;due to the fact that the shell and the clamping needles are arranged, so that damage to the alveolar bone caused by screw-in of threads can be avoided when the dental implant structure is implanted;and the diameter of the arranged shell is larger than that of the implanting rod, thus being more convenient when driving.
