Abstract: Porous craniomaxillofacial implants may include a plurality of polymeric particles sintered together at a plurality of contact points to form a porous network having pores; and an antioxidant disposed on a surface of at least some of the polymeric particles and/or in the pore of the porous network, so as to stabilize the implants from at least some oxidative damage during storage, transportation, and/or implementation (in vivo and/or ex vivo). Preferably, the polymeric particles include at least one of polyethylene, a polyethylene-polypropylene copolymer, a polyethylene-polybutylene copolymer, polytetrafluoroethylene, and expanded polytetrafluoroethylene.
