SUMMARY:

This study aimed to evaluate the effectiveness of lyophilized hydrolyzed collagen sponge biomaterial (Hemospon®). A controlled, randomized, blinded clinical study was conducted. Eighteen extractions were performed, where the treated alveoli were randomly selected and divided into two groups G1 (test) and G2 (control) with 9 alveolus each. The alveolus were analyzed in the horizontal and vertical directions by means of cone beam computed tomography, before and after 30 days of surgery, and the tomographic results were evaluated using the Wilcoxon and Mann-Whitney tests, assuming a statistical significance of p <0.05. In addition to tomographic analyzes, tissues were clinically evaluated for possible complications. From the results it was found that in a joint analysis assessing height (p <, 0.863), total length (p <1,000) and total thickness of the socket (p <0.222), no significant differences were observed between the test and control groups, respectively . Evaluating the parameters independently of the groups for alveolus height (p <0.012) and total alveolus thickness (p <0.001), significant differences were observed, but not in the analysis of alveolus length (p <0.107). In a separate analysis of the parameters for each test and control group, statistically significant differences were observed for the total thickness in the test group (p = 0.008), while for the alveolar height (p = 0.086) and total alveolar length (p = 0.123) significant statistical differences were observed. In general, clinically there was no difference between the groups regarding tissue healing in relation to inflamed gingival tissues and bleeding. No socket evolved with suppuration. It is concluded that the alveoli treated with Hemospon® had smaller bone losses, mainly in relation to thickness, which can be a biomaterial potential for alveolar preservation and was clinically satisfactory in the gingival tissue healing process, with no complications. However, a longer period of tomographic and clinical follow-up is suggested.
