The production of bioceramic powders and bioceramic implants are described and an additive manufactured implant used for tissue reconstruction and a method for manufacturing the implant are disclosed. The implant may be fabricated at least in part from suitable bioceramic powders produced using tailored mineral compositions tailored to the unique material properties of the tissue being replaced. The implants may be tailored to a three-dimensional shape and mechanical properties of the tissue defect designed to be replaced by surgical implantation of the device. Native tissue repair and regeneration at the site of implantation are also provided.

Bioceramic implants matched to patient specific and bone specific geometry

Methods and compositions for producing flowable compositions, e.g. pastes, that set into calcium phosphate products are provided. In the subject methods, dry reactants that include a calcium source and a phosphate source are combined with a setting fluid to produce the flowable composition. A feature of the subject methods is that the dry reactants include a particulate calcium and/or phosphate reactant having a mean particle size of less than about 8 &#x3bc;m and narrow size distribution. Also provided are the compositions themselves as well as kits for use in practicing the subject methods. The subject methods and compositions produced thereby find use in a variety of applications, including the repair of hard tissue defects, e.g., bone defects.

Calcium phosphate cements and methods for using the same

Temperature-insensitive calcium phosphate cements and methods of using the same are provided. Aspects of the cements include a dry component having fine and coarse calcium phosphate particulate reactants and a setting fluid which includes a cellulose. The dry component and setting fluid may be combined over a broad temperature range to produce a flowable composition. The resultant flowable composition finds use in a variety of different applications, including the repair of hard tissue defects, e.g., bone defects such as fractures.

Temperature-insensitive calcium phosphate cements

Methods of employing bone defect filling, e.g., orthopedic cements, such as calcium phosphate cements and the like, are provided. A feature of the subject methods is that vibration is employed in conjunction with the use of the cement, e.g., in preparation of the cement, in preparation of the target site, in delivery of the cement to the target site, and/or following delivery of the cement to the target site. Also provided are devices, systems and kits that find use in practicing the subject methods. The subject methods, devices and systems find use in a variety of different applications.

Use of vibration with orthopedic cements

Rapid setting high strength calcium phosphate cements and methods of using the same are provided. Aspects of the cements include fine and coarse calcium phosphate particulate reactants and a cyclodextrin which, upon combination with a setting fluid, produce a flowable composition that rapidly sets into a high strength product. The flowable compositions find use in a variety of different applications, including the repair of hard tissue defects, e.g., bone defects such as fractures.

Rapid setting high strength calcium phosphate cements comprising cyclodextrins

Methods of employing bone defect filling, e.g., orthopedic cements, in conjunction with hard tissue securing devices, e.g., screws, plates or rods, are provided. A feature of the subject methods is that the cement is introduced to a target bone site through a passageway of the securing device while a vibratory force is applied to the securing device. Also provided are systems and kits that find use in practicing the subject methods. The subject methods, devices and systems find use in a variety of different applications.

Use of vibration in composite fixation

Methods are provided for producing compositions, e.g. pastes or clays, which rapidly set into high-strength calcium phosphate products. In the subject methods, dry reactants that include calcium and phosphate sources, as well as a monovalent cation dihydrogen phosphate salt, are combined with a setting fluid and the combined reactants are mixed to produce the settable composition. A feature of the invention is that cements rapidly set into high strength product compositions. Also provided are the compositions themselves as well as kits for preparing the same. The subject methods and compositions produced thereby find use in a variety of applications, including hard tissue repair applications.

Rapid setting calcium phosphate cements

Methods for preparing a tricalcium phosphate coarse particle composition are provided. Aspects of the methods include converting an initial tricalcium phosphate particulate composition to hydroxyapatite, sintering the resultant hydroxyapatite to produce a second tricalcium phosphate composition and then mechanically manipulating the second tricalcium phosphate composition to produce a tricalcium phosphate coarse particle composition. The subject methods and compositions produced thereby find use in a variety of applications.
