Tibial bone defects was performed in six Santa Inês breed ewes and implanted with chitosan, collagen and hydroxyapatite biomaterial. One limb was considered the control limb and the other one the biomaterial limb, chosen randomly. Thermographic and Power Doppler sonography was performed in all animals, weekly for 56 days. The thermography showed no significant differences related to low, high and mean temperature between the control and the biomaterial groups. Statistical variations were found between time in both groups. The visualization of neovascularization with the Power Doppler sonography did not present statistical differences, except for day 21 (P=0,031). Within the possibilities provided by imaging exams, thermography and Power Doppler sonography demonstrate to be non-invasive methods for post-operative evaluation of inflammatory process and neovascularization. The weekly management allowed reliable and detailed monitoring throughout the experiment, without causing discomfort or stress to the animals. There was no evidence of biomaterial complications.
