摘要:
A maxillary barrier membrane is a device that physically supports the elevated schneiderian membrane during a non-grafted sinus-lifting procedure. The device is inserted into an open space formed by creating a lateral bony window at the desired location and elevating the schneiderian membrane. The device is inserted into the open space in between the maxillary sinus floor and the elevated schneiderian membrane to provide support. The device features a sealing membrane that forms a seal around the lateral bony window. An at least one primary supporting member is connected to a rigid base that is embedded into the sealing membrane. The at least one primary supporting member provides a tenting effect to the elevated schneiderian membrane. The at least one primary supporting member may be adjusted and reoriented in order to accommodate the open space.

A temporarily implantable tissue separator comprises (a) a membrane having two substantially-smooth surfaces and (b) an extractor for withdrawing said membrane from the operation site after a healing period through a minimal surgical incision. The membrane is conformably placeable between tissues to be separated. The extractor has a distal end and a proximal end. The distal end of the extractor is continuously connected to the membrane and the proximal end remains loose outside the tissue.

Tool and method for creating a perforation or cavity in a bone or bone structure in contact with a membrane, the tool including a drill having a free end and a channel adapted for supplying a liquid under pressure to the free end, the tool further including a source of the liquid under pressure such that the liquid flows partially into and through the bone or bone structure toward the membrane while drilling the bone or bone structure with the drill, which allows to perform a progressive detachment of the membrane when the drill is close to the membrane while still being inside the bone or bone structure, and before completely piercing the bone or bone structure.

Disclosed is a reamer for implant surgery including: cutting front end portions each of which has a sharp front end; cut edges of a horizontal line form, the cutting front end portions and the cut edges being arranged radially and alternately, wherein one side of the cutting front end portion having the sharp front end has a triangular depressed face inclined downwardly toward a rotation central axis of the cutting part, and one side of the cut edge having the horizontal line form has a triangular inclined face inclined downwardly toward the outer circumferential surface of the cutting part, wherein an inclination angle of a side inclined edge inclined downwardly at the sides of the outer circumferences of the cutting front end portion and the cut edge becomes gradually smaller in the rotation direction of the cutting part.
摘要:
A method and a dental implant system for accessing selected intra-cavity locations there-through that includes: (a) a dental implant having a plurality of openings configured for being implanted in an intra-cavity area of a patient, wherein each one of the plurality of openings allows access from an external area of the dental implant to a space in the intra-cavity area between the implant and a jawbone of the patient, when the dental implant is installed in the intra cavity; and (b) one or more directing element that is removably securable to the dental implant, wherein the directing element includes openings and is configured to allow access to one or more specific locations at this space through a selected at least one of the plurality of openings of the dental implant, when secured thereto.
摘要:
A bone harvesting device is disclosed as including a drill body for drilling into bone, the drill body being rotatable about its central longitudinal axis, and a saw pivotable relative to the drill body about a pivoting axis parallel to the central longitudinal axis of the drill body, the drill body including a cavity which opens at a lower open longitudinal end of the drill body, and the saw being pivotable relative to the drill body between a first position in which the saw is clear of the lower open longitudinal end of the drill body and a second position in which the saw blocks part of the lower open longitudinal end of the drill body.
摘要:
A dental implant apparatus and method of use which has a central conduit and a plurality of apical apertures through which fluid bone-grafting material may be extruded. A resorbable membrane surrounds the apical end of the apparatus and unfurls as bone-grafting material exits the apertures, thereby holding the fluid in close proximity to the implant.
摘要:
An arrangement and an implant are provided for increasing the stress resistance of the implant arranged in an upper jaw bone. The implant has access via parts to the sinus cavity. At said parts, the implant is arranged with a convex or rounded front surface which, upon access, lifts the sinus mucous membrane, without piercing the latter, and thus forms a closed space between the parts and the underside of the mucous membrane. The implant is provided, at least at said parts, with growth-stimulating substance or substances which interact with cell-containing body fluid which penetrates or has penetrated into the space, so that new bone is formed around said parts of the implant.
摘要:
A method is provided that includes advancing a drill having a distal end through an occlusal cortex into trabecular bone of an alveolar ridge, and ceasing the advancing of the drill when the distal end of the drill reaches an occlusal surface of a superior cortex of the alveolar ridge. Other embodiments are also described.
摘要:
An implant includes a collar configured for disposal within tissue. The collar defines an axial bore. A shaft extends between a first end and a second end. The shaft is configured for disposal with the bore of the collar. A base defines an axial bore having an inner surface configured for engagement with the shaft such that the base is axially movable relative to the shaft. At least one arm extends between the collar and the base. The at least one arm is movable via axial movement of the base relative to the shaft between a first position and a second position such that the at least one arm is expanded in a configuration to engage tissue. Methods of use are also disclosed.
