A non-percutaneous prosthesis, reconstructive sheeting and composite material which exhibit excellent tissue adhesion, outstanding biocompatibility, moldability, trimability and flexibility are disclosed. The non-percutaneous prosthesis, reconstructive sheeting and composite material can be easily molded into various shapes, trimmed with a scalpel and deformed during prosthetic positioning. The non-percutaneous prothesis comprises a biocompatible composite material which is made of an elastomeric material and bio-active ceramic or glass particles and has a predetermined shape. The bio-active ceramic or glass particles are dispersed throughout a matrix of the elastomeric material having a predetermined shape, or the elastomeric material is formed to the predetermined shape and the bio-active ceramic or glass particles are coated on a surface of the elastomeric material. In another embodiment, the non-percutaneous prosthesis comprises a base material of predetermined shape and a layer of elastomeric material provided on the base material, wherein a layer of elastomeric material has distributed therein or provided thereon bio-active ceramic or glass particles. The elastomeric material is preferably one of silicone, polyurethane and its derivatives, hydrogel and C-Flex TM and, more preferably, is silicone or hydrogel. The bio-active ceramic or glass particles are preferably made of hydroxylapatite. The reconstructive sheeting comprises a biocompatible composite material made of an elastomeric material and bio-active ceramic or glass particles. Also, the present invention provides a biocompatible composite material comprising hydrogel and particles of a bio-active ceramic or glass material. The particles are preferably dispersed throughout a matrix of hydrogel.
