A medical method of affixing an element to a surface of dentine, tooth enamel, bone tissue, or corresponding substitute material. The method includes the steps of: providing an attachment composition, the attachment composition having a mixture of: a thermoplastic component; and a hardenable (for example curable) component. The hardenable component is different from the thermoplastic component. The method further includes the steps of: positioning the attachment composition relative to the surface of dentine, tooth enamel, bone tissue, or corresponding substitute material; and activating the attachment composition to attach to the surface or to attach to the element positioned relative to the surface. The step of activating the attachment composition includes activating the attachment composition by means of mechanical vibration.

A surgical method is provided, the method including the steps of: providing an artificial or allograft flexible planar structure; providing an implant, the implant including material liquefiable by mechanical oscillation, exposing a surface region of hard tissue or hard tissue substitute material; positioning the implant on an exposed area of the hard tissue or hard tissue substitute material; and fastening the implant to the hard tissue or hard tissue substitute material by impinging the proximal end of the implant with mechanical oscillation and simultaneously pressing the implant against the hard tissue or hard tissue substitute material while the distal end of the implant protrudes into a cavity of the hard tissue or hard tissue substitute material and regions of the liquefiable material are in contact with the hard tissue or hard tissue substitute material, and thereby liquefying at least a portion of the liquefiable material, and letting the liquefiable material resolidify.
摘要:
A system and method of angularly stable fixation of an implant on a bone includes the steps of making at least one hole in the bone by means of a bone drill. An implant is placed on the bone in a desired position and joining the implant with the bone, such that the implant is prevented from rotation about its attachment point. A system is provided for use in the above described method. The system comprises a bone drill, an implant and a sonotrode for angularly stable fixation of the implant on the bone. The system can further comprise a joining element to join the implant with the bone.
摘要:
Elements (5) such as dental fillings, inlays, dental veneers, root pins, implants to be implanted in bone tissue, or endoprostheses are affixed to surfaces (3) of dentine, tooth enamel, bone tissue, or a corresponding substitute material, by providing the element with element surfaces (6) including a first thermoplastic material, by equipping the surfaces (3) of dentine, tooth enamel, bone tissue, or a corresponding substitute material in a preparatory step in such a way that they become weldable with the first thermoplastic material, and by welding the element surfaces (6) to the pre-treated surfaces (3) by e.g. exciting the appropriately positioned element (5) with mechanical vibrations. The pre-treatment of the surfaces (3) in the preparatory step is achieved by attaching solid bodies (2) including a second thermoplastic material to the surfaces (3), with the aid of a curable compound (generally known for preparatory treatment of dentine or enamel surfaces) or with the aid of a cement.
摘要:
For dispensing a material with thermoplastic properties in a flowable state at an operation site in a human or animal patient, a device is used, which includes the material having thermoplastic properties in a solid state and is equipped for bringing the material into a flowable state at a distal device end positioned at the site where dispensing is desired and for driving the flowable material from this distal device end. The device comprises a rotation drive, a consumable element and a dispenser element, wherein one of the two elements is coupled to the rotation drive and wherein the consumable element comprises the material to be dispensed. The two elements are arranged with parallel longitudinal axes and the dispenser element comprises a distal end piece with a proximal face against which a distal face of the consumable element is held and advanced during dispensing.
