RESUMO

Background: Preventing ridge collapse with the extraction of maxillary anterior teeth is vital to an esthetic restorative result. Several techniques are available to regenerative procedures and are used for socket preservation. The aim of this study was to analyze by clinical parameters the use of acellular dermal matrix (ADM) and anorganic bovine bone matrix (ABM) with a synthetic cell-binding peptide P-15 to preserve alveolar bone after tooth extraction. Methods: Eighteen patients in need of extraction of maxillary anterior teeth were selected and they were randomly assigned to the test (ADM plus ABM/P-15) or control (ADM only). Clinical measurements were recorded at initial and 6 months after ridge preservation procedures. Results: In the clinical measurements - External Vertical Palatal, External Vertical Buccal and Alveolar Horizontal (EVPM, EVBM and AHM) -, the statistical analysis showed no difference between test and control groups in the initial and at six months. The intragroup analysis, after six months, showed a statistically significant reduction in the measurements for both groups. In the comparison between the groups, the differences (mm), in the test group, were: EVLM=0.83±1.53, EVBM=1.20±2.02, AHM=2.53±1.81 and in the control were: EVLM=0.87±1.13, EVBM=1.50±1.15, AHM=3.40±1.39. The differences in EVLM and EVBM measurements were no statistically significant; however, in horizontal measurement (AHM), there was statistically difference (p<0.05). Conclusion: The results of this study show that ADM, with or without ABM/P-15, can be successfully when it is used as a membrane for preservation of alveolar ridge after tooth extraction of maxillary teeth earlier.
