Disclosed is a safety subantral membrane lifter including a bone-fixing unit including a bone-fixing arm mounted on the top of the bone-fixing unit, a bone-fixing unit body arranged at the lower end of the bone-fixing unit, and a bone-fixing unit support arranged at the lower end of the bone-fixing unit body. The bone-fixing unit includes a bone-fixing unit body; a bone-fixing arm arranged at one end of the bone-fixing unit body and which is inclined toward one end thereof, two side blades protruding outwardly from both sides of the bone-fixing unit body and formed in the vertical direction so as to be sharp, and a bone-fixing support arranged at the lower end of the bone-fixing unit.

A dental implant has a hollow shell with outer bio-compatible surface for engaging a soft tissue socket left in gingival tissue after a tooth has been extracted, to promote healing. The shell tapers outwardly from a first to a second perimeter, the second perimeter being asymmetrically scalloped with opposite distal and mesial peaks and opposite lingual and facial valleys between the peaks. A dental implant in the bone socket left after tooth extraction is rigidly connected to a temporary post, the temporary post extending in the shell. The shell engages against the soft tissue socket without gaps and without requiring alignment between the shell and implant axes.

A method for performing an inferior lift in a sinus includes preparing an initial opening in a bone including a marrow section and a hard sinus floor, the initial opening being drilled through the marrow section to a depth just prior to reaching the hard floor of the sinus. A portion of the hard sinus floor is removed using a sonic drilling device. Subsequently any remaining doughnut shaped hard floor of the sinus is removed using a second tip on the sonic drilling device that has an active portion that is substantially limited to 360 degrees about the circumference of the forward direction of the tip but without any forward cutting surface, the second tip configured to remove bone only in the lateral direction of the second tip without substantial cutting contact with the marrow section of the bone clearing a widened opening in the hard sinus floor of the bone.

An accurate and precise surgical guide for dental procedures, especially a procedure involving a subject with few or no teeth as well as methods for making and use of such guides.

A composition delivery source (200) is provided that includes (a) a chamber (202), which is shaped so as to define (A) one or more liquid ports (310) in fluid communication with an interior of the chamber (202), and (B) one or more solid-liquid composition ports (312) in fluid communication with the interior of the chamber (202); (b) a solid-liquid composition delivery tube (314) in fluid communication with at least one of the one or more solid-liquid composition ports (312); (c) a mixing tube (316) in fluid communication with at least one of the one or more liquid ports (310) and at least one of the one or more solid-liquid composition ports (312); and (d) a liquid-supply tube (318) in fluid communication with at least one of the one or more liquid ports (310). A pump unit (201) includes one or more pumps (223), which are arranged to cause flow in the mixing tube (316) during a mixing activation state (342), and to cause flow in the liquid-supply tube (318) during a particle-delivery activation state (344).

An osteotome for sinus lift procedures includes a body interchangeable with various handles. The body includes a shaft that is releasably received into the handle, and a tip portion. The tip portion may be directly utilized for ridge expansion/bone compression, or a succession of tip members may instead be received thereon to provide suitable diameter escalation to create the socket. A conduit in the tip portion interconnects with a conduit in a hydration port and a conduit in a tip member. A hose couples the hydration port to a syringe, to deliver fluid out the tip member to lift the membrane. Graduated syringe markings permit delivery of measured fluid quantities to control the amount of lift. A second hydration port is coupled to a graduated cylinder through a valve, which is opened after lifting is complete, to measure the fluid released. A loss of fluid measured indicates a sinus tear.

A device, for atraumatically elevating the Schneiderian membrane during a sinus lift procedure with positive, real-time indication of the amount of lift occurring, may include: a first conduit; a first balloon coupled to a first end of the first conduit and in fluid communication therewith; a second conduit; a second balloon coupled to a first end of the second conduit and in fluid communication therewith; and means for infusing a fluid into the first and second conduits to cause inflation of the balloons. The balloons may be constructed the same, or may be individually tailored. The first balloon is configured to be received within the implant socket and apply pressure to the membrane. The second balloon, expanding against atmospheric pressure only, is configured of a different material and wall thickness. An integral scale behind the second balloon provides indication of the inflation and lift provided by the first balloon.

A sinus implant includes an implant body having a mounting hole axially defined there through; a plurality of positioning threads that are provided in a periphery of the implant body, that extend spirally upwardly around the periphery of the implant body, and that have a width that gradually decreases in a direction from a bottom end of the implant body toward an opposing top end of the implant body; a pushing tip that protrudes from a top end of the sinus implant, that has a diameter that is reduced compared to that of the implant body, and that includes a flat end face having defined therein a recess space; and at least one spiral groove that extends around the periphery of the implant body across the plurality of positioning threads, that reaches the periphery of the pushing tip, and that intersects with and communicates with the recess space.

Devices and methods to perform elevation of the Schneiderian membrane in a safe, easy and minimally invasive manner are described. The devices include a cannula and a balloon. A liquid can be introduced through the cannula inside the maxillary sinus below the Schneiderian membrane to elevate the Schneiderian membrane. The balloon can be inflated through the cannula so the balloon will be expanded inside the maxillary sinus below the Schneiderian membrane while being surrounded by the liquid which was previously introduce inside the maxillary sinus. The expansion of the balloon is safely further elevating the Schneiderian membrane in a controlled amount and location.

A method for performing an inferior lift in the sinus includes preparing an initial opening in the bone that is drilled to a depth just prior to reaching a sinus floor. Using a sonic drilling device, a final portion of the sinus floor is removed until a schneiderian membrane is reached. A bone graft is inserted into the opening, lifting said schneiderian membrane. After ossification of the bone graft, an implant is inserted into the opening and graft.
