    摘要: Ceramic precursor compositions and chemically bonded ceramic (CBC) materials, especially Ca-based, and a composite biomaterial suitable for orthopaedic applications. The CBC-system includes a binding phase (chemical cement) and additional phases with specified chemistry imparting to the biomaterial the ability of initial strength followed by interaction with the body tissue including body liquid, to form a resorbable or partly resorbable biomaterial. The ceramic precursor composition includes at least one silicate with Ca as the main cation with a resorption rate less or equal to that of the bone in-growth rate. The silicate will form the binding phase of the cured material. Implants and surface coated devices are also disclosed. The cured material exhibits a compressive strength exceeding 100 MPa.

    摘要: The present invention deals with the initial hydration reaction of highly alkaline chemically bonded ceramic systems such as Ca-aluminate and Ca-silicate, exhibiting a controlled pH development, reduced from very high levels to be in a pH range of 7-9 by the use of an internal buffer system added to the CBC type biomaterial used. The invention is especially intended for endodontic, orthopaedic applications and/or soft tissue applications and/or drug delivery carrier applications.

    摘要: The present invention relates to a coated medical implant wherein the coating comprises an amorphous Me oxide layer or an (Al, Me) oxide layer deposited by physical vapor deposition, and wherein Me can be one or more of the elements of Ti, Si, Cr, Hf, Zr, Ta or Nb. The PVD layer does not have any bioactive/osseointegrating properties at temperatures below 45° C. This makes it easy to remove the implant after it has being inserted in an animal or human body, e.g. when used for fixating fractures. The coating may further comprise a calcium phosphate layer, preferably a hydroxyapatite layer, which is grown on the PVD layer using a biomimetic process. The coating may be loaded with a releasable agent such as a pharmaceutical agent, an ion or a bio molecule. The present invention also relates to a method for forming the coated medical implant.
