Objective: This work is aimed at evaluating the response of the marginal bone crest using the implant’s platform as a reference. The study considered patients with alloplastic grafts from Madrob® to establish the role of bone integrity in locating dental implants. Materials and Methods: The benchmark and prospective studies were conducted on 30 subjects .A total of 81 alveoli alloplastic implants were analyzed post-exodontia. The response of the marginal bone crest was evaluated after 3, 6, 9, 12, 24 and 36 months via clinical and radiographic controls Results: For the period between 12 and 36 months, mesial prevailed over distal bone loss. Mesial and distal gains of about 0,05 mm were equally important for the period between 24 and 36 months. p-values less than 0,001 indicate that differences between times are all significant. The ANOVA indicates that all the variances are homogeneous and small between 0,18mm and 0,22mm.
