    摘要: A flowable, paste-like composition capable of setting in a clinically relevant period of time into an antimicrobial agent loaded apatitic product having sufficient compressive strength to serve as a cancellous bone structural material is provided. The subject compositions are prepared by combining dry ingredients with a physiologically acceptable lubricant and an antimicrobial agent, where the dry ingredients comprise at least two different calcium phosphates. The subject compositions find use in a variety of different applications, including orthopaedic, dental and cranio-maxillofacial applications.

    摘要: The present disclosure is directed to a bioresorbable ceramic composition having a plurality of biocompatible ceramic granules, each of the granules having a coating of a plurality of calcium containing particles, where at least a portion of the particles are bound to at least a portion of an outer surface of each of the granules, and further where the composition is flowable in a dry state. The present disclosure is also directed to a three dimensional scaffold for bone repair that includes the bioresorbable composition, which upon implantation to a locus of repair defines an interconnected pore network between outer walls of the coated granules of the composition. Finally, the present disclosure is directed to methods of forming both the bioresorbable ceramic composition and the three-dimensional ceramic scaffold.
