Abstract:
A dental implant is provided for facilitating viewing an outside of a distal end thereof via a proximal opening thereof, and/or for providing bone graft material via selectively closable one or more distal openings. A dental implant installation procedure is also provided in which a distal end of a dental implant is projected into a paranasal sinus cavity or a nasal cavity to thereby displace the respective sinus membrane or nasal cavity membrane from the respective cavity floor, while minimizing risk of damaging the respective membrane. Bone graft material is introduced into the space thereby created between the respective membrane and the respective cavity floor via a distal portion of the dental implant to thereby form a desired sinus augmentation.

Abstract:
Disclosed is a drill for implant operations. The drill for implant operations of the present invention includes a drilling body comprising a hollow cylindrical shape and having a top with a cutter, and a female screw unit arranged on an inner wall of the drilling body to catch a part of an alveolar bone separated from the latter during the drilling of the alveolar bone. The present invention enables alveolar bone drilling processes to be carried out with ease, and enables fragments of alveolar bone to be removed with ease during the drilling of the alveolar bone, thus shortening the time required for drilling the alveolar bone.
Abstract:
A drill for sinus membrane lift includes a contact surface for coming in face contact with sinus membrane, the contact surface having a curved periphery, and a bone-maintaining area connected to the contact surface for storing and discharging drilled bone fragments. The bone- maintaining area includes a first inside wall and a second inside wall connected to the first inside wall, the first inside wall oriented in a drilling direction, and the second inside wall opposite the first inside wall. The first inside wall has a drilling surface and is formed higher than the second inside wall so that the drilling surface is exposed in the drilling direction. The front end of the head comes into face contact with the sinus membrane at a wide area to prevent the sinus membrane from being torn or damaged even if the head completely penetrates the maxilla and contacts the sinus membrane.
Abstract:
An internal sinus procedure for patching a perforation (14) in patient's sinus membrane (12) comprising the steps of (i) creating an opening (10) in the sinus floor (22) of a patient to expose the portion of the sinus membrane including the perforation (14), (ii) inserting a quantity of a sinus membrane patching material (36) through the opening to a location adjacent the sinus perforation (14) and (iii) laterally expanding and forcing the patching material (36) against the sinus membrane (12) to seal the perforation.
Abstract:
A device includes a tubular element, and a cutter spring-biased relative to the tubular element. In an unloaded configuration the cutter is displaced relative to the tubular element by a displacement distance, and when the cutter is in a loaded configuration the displacement distance is reduced. A first structure is longitudinally fixed relative to the cutter and rotationally engaged relative to the tubular element. A length of the first structure extends proximally in the unloaded configuration. A second structure is longitudinally displaceable relative to the first structure. In the loaded configuration, a driver engages and rotates both the first and second structures, and thus the tubular element and cutter together. Once the cutter breaks through the bone, the cutter spring-biased into the unloaded configuration, resulting in disengagement of the first structure from the driver to prevent rotation of either the tubular element or the cutter.
