Histocompatibility of porous ceramics in the jaw bones of Cavia cobaya

: Porous ceramic basically fuses hard in osseous connective tissue of the jaw if closed implantation has been successful. The date were derived from ground serial sections in different postoperative intervals. Light, fluorescence (after intravital staining), and scanning electron microscopy were used for the evaluation. The positive results obtained with this test series do not imply that porous ceramic material used as root replacements persists under normal masticatory stress and in the same type of tissue.
