Marginal Bone Level Around Titanium Implants Produced by Additive Manufacture

This randomized Split-mouth clinical study of non-inferiority will monitor for one year partially edentulous patients in the posterior region of the mandible or maxilla, rehabilitated with 2 implants (AM) in the same Arch to evaluate the success rate of the implant, one loaded at 30 days after installation and the other at 90 days. Changes in marginal bone level and osseointegration success will be evaluated, with visits and data collection in 0 days (baseline), 30 days, 90 days, 6 months and 1 year
