Abstract
The invention relates to porous ceramic composites incorporating biodegradable polymers for use as a bone substitute in the fields of orthopedics and dentistry or as a scaffold for tissue engineering applications. The porous ceramic composite implant for connective tissue replacement comprises a porous ceramic matrix having a biodegradable polymer provided on internal and external surfaces of the ceramic matrix. The biodegradable polymer allows for the passage and/or delivery of a variety of agents throughout the porous ceramic matrix and improves mechanical properties of the implant in vivo.
