Abstract: This invention sets forth an agent for filling bone and tooth defects, for building up bone, for bone-contact layers and for the replacement of bones and the roots of teeth, which contains calcium phosphate apatite having carbonate and alkali portions, all ions being definedly integrated in the crystal lattice; use is optionally made together with additives and/or diluents both tolerated by the body. Furthermore, it sets forth the use of this apatite for filling bone and tooth defects, for building up bone, for bone-contact layers, as a replacement for bones and the roots of teeth and as an implant article consisting completely or partially of this apatite or consisting of a material known for implant articles and being coated completely or partially with a layer of this apatite.

Abstract: A connecting device is disclosed for operatively interconnecting a superscture element and an implant member having at least one bore, which device includes a rod member made of a material of construction having a high modulus of elasticity and which device further includes a projection means made of the same material of construction as used for the rod member, or a dissimilar material, and the device further including, as required, an envelope means. There are further disclosed an implant member which includes the aforesaid connecting device, and a method for arranging the connecting device in an implant member.

Abstract: An arrangement for the conveyance of a sterile liquid to a surgical treating or operating location, consisting of a liquid receptacle containing the sterile liquid, from which there can be dispensed the sterile liquid under the effect of pressure through a dispensing conduit from the dispensing end thereof, wherein the dispensing conduit is provided with a valve arrangement for regulating the throughflow.

Abstract: A dental implant having a sintered and porous surface and comprising a biocompatible ceramic matrix and, intermixed therein, inorganic fibers.

Abstract: A method is disclosed for the preparation of implants, especially dental implants, from ceramic substances having in particular a porous surface which stimulates ingrowth of bone tissue.

Abstract: A corrective agent used for the covering and/or filling of bone defects, comprising a solution forming a gel at body temperature which comprises a physiological saline solution containing at least one polysaccharide and/or gelatin. Other additives may also be present.The corrective agent can be prepared by boiling the at least one polysaccharide and/or gelatin in the physiological saline solution to dissolve and sterilize. The corrective agent is then generally maintained above the temperature at which solidification to a gel occurs until use, though it may be gelled and once reheated. Other additives may also be present, with time of addition depending upon the thermal susceptibility of the additives.The corrective agent is used by coating the same on the area to be covered and/or filled.
