Disclosed is a lateral wall supported implant system having a supporting screw surgical guide. According to the present invention, there is provided the lateral wall supported implant system including: a primary screw placed in the alveolar bone; a surgical guide disposed on a lateral wall of the alveolar bone with the primary screw placed therein; and supporting screws passing through the surgical guide and the lateral wall and then coupled to the primary screw to provide supporting forces for the primary screws so that the primary screw is supported against the lateral wall to have the primary stability thereof.

A dental implant includes a fixture implanted into an alveolar bone, an abutment fixed to an upper part of the fixture and having a core hole formed in a center of an upper surface of the abutment, a crown bonded to an upper outer side of the abutment and having a passage vertically formed through a center of the crown, and a cover screw having a screw screw-fastened to the core hole and a head in close contact between an upper surface of the abutment and a lower surface of the crow to cover the core hole, in which, when the screw is released by a tool passing through the passage, the head moves up so that the cover screw provides a separating force to the crown. The dental implant may facilitate a separation of the crown and prevent binding force from weakening, thereby enabling an efficient procedure and management.

The invention is a fastener for medical or dental use which requires minimal preparation of a site in bone. According to one embodiment the fastener includes a shank and a head having an aperture with a torque-receiving aperture such as a threaded hole or a polygon such as a hex-sided hole. The other end of the shank is a blunt or a sharp point. Another embodiment includes a radially spaced apart series of splines each having a linearly spaced apart series of barbs. An alternative embodiment includes on the shank a radially spaced apart series of linear arrays of barbs emerging from the shank itself. The linear spacings may be staggered from one radial line to the next so that as a whole the barbs are arranged into one or more continuous helicies.

A retainerless orthodontic dental implant system for positioning the mandible forward relative to the maxilla and for facilitating optimal airflow during sleep and a method of using such a system.

A device configured to engage and hold a structure (e.g., pin) to be inserted in a hole or opening of a target structure (e.g., a surgical guide) during a surgical procedure (e.g. a dental implant procedure). The device can include a first arm having a first arm end portion with a first groove. The device includes a second arm coupled to the first arm, the second arm including a second arm end portion with a second groove. The device can be transitioned between an open position and a closed position, In the closed position, the first groove of the first end portion and the second groove of the second end portion form an enclosure to securely engage at least a portion of a pin.

A coupling element for dentistry applications having a tubular body which forms an internal duct that is open outward at respective ends of the body. A first end forms a first inlet for the insertion in the duct of the head of a pin which can be coupled directly or indirectly to a maxillary bone tissue. The first end has a recess provided along the edge of the first inlet and forms a guiding portion for the insertion of the head of the pin; along a segment of the duct which is contiguous to the first inlet there is a protrusion which is substantially aligned longitudinally with the recess, for contrasting the accidental rotation of a ring provided with a respective discontinuity, which can be arranged in the segment in order to lock the head of the pin.

A zygomatic implant for supporting a dental bridge is provided. The zygomatic implant has a stem with a longitudinal axis having a threaded apical portion, an intermediate portion, and a neck portion having a seat for attachment of an abutment. The zygomatic implant has a head with a polygonal cross section that protrudes atop the neck portion, and two internal threads, each having an axis orthogonal to the longitudinal axis of the stem and a mouth located on a lateral wall of the stem. The two internal threads are arranged longitudinally offset along the longitudinal axis of the stem.

Systems and methods are provided for enhancing osseointegration performed in conjunction with placing a dental implant. A dental implant post can be used for applying current to the implant site as well as for anchoring an artificial tooth. Such a dual purpose implant can allow faster healing and osseointegration time as well as enabling the use of dental implants in a large segment of the population currently disqualified from such treatment due to poor bone quality.

An abutment screw having a first hardness for use in affixing a dental prosthetic, having a second hardness less than the first hardness, to an abutment that itself is attachable to an implant in the mouth of a patient includes a head and a body. The body includes a smooth shank immediately proximate the head, and a threaded portion comprising a helical ridge that runs around its body, the helical ridge beginning at a point along the body distal the head portion. The head includes an upper surface, having a drive at a central portion thereof, and an underside surface having a convex radiused curvature extending until it meets the shaft, the convex radiused curvature being configured to conform to a corresponding concave curvature of a receiving portion of the prosthesis.

The device can include a first arm having a first arm end portion with a first groove. The device includes a second arm coupled to the first arm, the second arm including a second arm end portion with a second groove. The device can be transitioned between an open position and a closed position, In the closed position, the first groove of the first end portion and the second groove of the second end portion form an enclosure to securely engage at least a portion of a pin.
