HE staining of ectopic bone formation in nude mice at 12 weeks (×100), Implant I can be seen partially degraded DBM stand, surrounded by fibrous connective tissue replaced; Implant II showed more mature bone structure of a small beam than other groups; both Implant III and IV showed small beam structure of bone with some cartilage-like structure partially visible, bone formation maturity lower than Implant II.
