T he human recombinant type 2 (rhBMP-2 Infuse?) is a bone morphogenetic protein capable of assisting considerably in cases of bone graft. This study aimed to evaluate the vertical bone growth of block-shaped xenogenous grafts fixed to the tibia of rabbits with and without rhBMP-2. We used 20 New Zealand female rabbits, weighing between 3.5 and 4 kg, which were divided into four groups: blocks without membranes associated with rhBMP-2, blocks with membranes associated with rhBMP-2, blocks without membranes and not associated with rhBMP-2, and blocks with membranes not associated with rhBMP-2. Two rectangular blocks were fixed to each tibia with screws at the same level as the surface of the blocks, and thereafter measured in millimeters using a pachymeter. After three months, the animals were euthanized and the blocks were again measured. Data were analyzed using Kruskal-Wallis/Tukey (α =0,05). Statistical analysis revealed that the interaction between the factors rhBMP-2 and Membrane was not significant (p = 0.114). Analyzing the factors individually, the groups without membrane (2.38 ? 1.08) presented a mean bone growth greater than the groups with membrane (1.72 ? 1.51). We came to the conclusion that the use of rhBMP-2 resulted in a greater vertical bone growth, and it is an option for the treatment of atrophic areas
