The first cast part can be positioned in a space of the second cast part and a gel slurry can be applied intermediate the first and second cast parts. The gel slurry can then be solidified to form a solidified gel slurry. The first cast part can then be removed together with the solidified gel slurry from the second cast part. The solidified gel slurry can then be machined to form an exterior shape corresponding to a desired exterior shape of the dental component. Finally, the solidified gel slurry can be sintered.

Abstract: A device is used for inserting resilient material between the vertebras in a spinal column. The device incorporates first and second units which support portions arranged to cause a separating action upon the vertebras via surfaces present thereon.

Abstract: An ordering and manufacturing system is used to produce all or part of a tooth replacement from gold. Functions are included for scanning or reading of the treatment situation. Computerized simulating and/or shape-determining functions determine the optimum or desired shape of the tooth replacement. The system is activated for ordering and manufacturing all or part of the tooth replacement. A module system is capable of selecting, from among various manufacturing materials and tools, a manufacturing material in the form of gold and a tool in the form of a casting tool. The module system controls or determines the supply or amount of gold to the casting tool. A dental crown or unit can be made of cast gold. A known ordering and manufacturing system can be used and retain its effective and rapid functions at the same time as another alternative for tooth replacement is presented on the market.

Abstract: A device, for example in the form of an implant, is arranged to be applied via at least one surface or one portion (for example an outer portion) to bone and/or tissue in the human body. An agent which stimulates bone growth, in the form of HA, is used in connection with the device. The device, the surface or the portion comprises or consists of compressed bone-compatible and/or tissue-compatible material in the form of titanium powder. The titanium powder is mixed with the agent, which is also in powder form, and a composite material is formed with the two powders by means of impact compaction. The invention also relates to a method and use in connection with devices of the type in question. A novel type of HA use is made possible and eliminates, inter alia, the disadvantages of loosening HA layers during production of the device.
