Introduction: the use of bone replacements in Dentistry has increased as a result of satisfactory and predictable clinical results, lower postoperative morbidity and affordable prices. The most common material used is still the inorganic bovine bone with osteoconductive properties. In the 1980’s began the search for a synthetic material with osteoconductive results equal or superior to inorganic bovine bone. Objective: To compare histological and histometric property of osteoconductive bone compound (GenMix, Baumer) with phosphate beta-tricalcium (GenPhos, Baumer) implanted in critical size defects in rat calvaria. Results: It was observed 32.5% of new bone formation in the group of compound bone and 45.9% in the phosphate beta-tricalcium group. Conclusions: Along the time of microscopic observation of this work, one can state that the materials studied are not absorbable and that phosphate beta-tricalcium is more osteoconductive compared to the compound bone..
