Abstract: A surgical device for tissue perforation (1) includes a perforation member (2), characterized in that it includes a stop (4) that presses on the outer surface of tissue (1) and is mobile relative to the perforation member, and reaction elements (3) configured to resist the movement of the stop (4) relative to the perforation member (2). The device will be used for the perforation of all types of tissue and especially bone tissues during which the withdrawal of the perforation member from the tissue is difficult.

Abstract: A device for bone regeneration includes an end section (1) for endosseous penetration, characterized by the fact that the end section (1) presents a primary cylindrical section connected to a conical section which ends in a tip, and that the end section (1) is provided with a coating of adamantine carbon with a mirror-polished surface. The device will find its application in the manufacture of surgical tools for bone reconstruction.

Abstract: A dental implant for lateral insertion includes a longitudinal shaft (1) and at least one lateral portion (2) oriented in a plane inclined relative to the longitudinal shaft (1) at least one zone having a relief bearing on the bone, inclined relative to longitudinal shaft (1) and configured to create a displacement of the entire implant with an axial component during implant insertion. The implant ensures a better hold in the receiving site and an easy insertion. The implant is useful in the field of dental surgery, especially the insertion, of dental prosthesis in edentulous patients.

Abstract: The invention relates to a dental implantology device combining a specific drill (21) which is adapted to jawbone density variations and an implant (1) which is formed in a corresponding manner to the drill (21) and which is also adapted to bone density variations. According to the invention, the implant (1) and the drill (2) comprise a plurality of zones over the heights thereof, which are suitably produced such that the drill (21) alone is used to form the seat for the implant (1). The invention is suitable for high-precision dental implantology.

Abstract: A dental implant (1) has a cylindrical body (2), with a rounded apical end (3) provided with formations (4, 5, 6, 7, 8) permitting internal bony regeneration firmly securing the implant (1). A basal end (9) forms a polygonal nut (10). The cylindrical body (2) has a succession of alternate flat parts (15, 16, 17, 18) and externally screw-threaded parts (11, 12, 13, 14), extending lengthwise of the body of the implant (1). The external threading increases the contact surface with the bone (20). The threaded parts (11, 12, 13, 14) are disposed at the periphery of circular sectors of the cylindrical body (2) and the flat parts (15, 16, 17, 18) are provided by the bottoms of longitudinal grooves. There are two wide threaded parts (11, 12) for self-tapping and/or retention in already-tapped bone (20) and two narrow threaded parts (13, 14) serving as guide rails during impacting and permitting the escape of chips during self-tapping.

Abstract: A method is provided for positioning a dental implant, comprising cutting a slot in a jaw bone with a tool comprising a shaft having a flat cutter wheel at one end of relatively large diameter and a plurality of relatively small cutter wheels spaced apart from said relatively large wheel and from each other along said shaft. The cutting is effected by moving the shaft normal to its axis so that the relatively large flat cutter wheel moves into the jaw bone while remaining in a single plane. Upon removing the tool from said slot, an implant is emplaced in the slot comprising a shaft having at one end a relatively large diameter wheel and a plurality of relatively small wheels spaced apart along said shaft from said relatively large wheel and from each other.

Abstract: A dental implant comprises a shaft having a smooth wheel of relatively large diameter on one end of the shaft and perpendicular to and coaxial with the shaft, and a plurality of relatively small wheels spaced along the shaft and spaced apart from each other and from the relatively large wheel. The relatively small wheels have each a cylindrical outer contour and have flanks that lie in planes parallel to each other and perpendicular to the axis of the shaft.

Abstract: A dental implant that serves as its own cutting tool for forming a T-shaped slot in a human tooth to receive the implant, comprises a flat circular wheel having cutting teeth on its periphery. The wheel has a diameter that is a plurality of times its thickness. An elongated shaft is secured coaxially to the wheel and has milling surfaces thereon that extend from the wheel a distance which is a plurality of times greater than the thickness of the wheel and a plurality of times greater than the diameter of the milling surfaces. The diameter of the wheel is a plurality of times greater than the diameter of the milling surfaces. A portion of the shaft extending beyond the milling surfaces in a direction away from the wheel permits the releasable securement of the implant to a dental drill.
