Objetives. The aim of this study is to establish a common protocol when orthodontic movements are applied in regenerated sites with bone grafts. Material and methods. A literature search using electronic databases, PubMed and the Cochrane Database of Systematic Reviews, was conducted using the following inclusion criteria: articles in english which included the keywords ‘’tooth movement’’ and ‘’bone graft’’. Due to few current literature found about this topic, no limit in years of publication was considered. The exclusion criteria was: studies in which the graft was made post-orthodontics and in which the regeneration was made only with tissues. Results. There is no unanimity on the latency time to initiate orthodontic forces in a regenerated area. It vary from immediately, up to 6 months. Bio-Oss and synthetic bone are the most used in alveolar regeneration followed by orthodontic movements. Studies demonstrated that samples grafted with synthetic bone obtain major quantity of bone formation and less root resorption
compared with Bio-Oss. Orthodontic forces used in animals samples vary from 50 to 450 gr. In all clinical cases continuous and light forces were preferred. Conclusions. The application of immediately or very early orthodontic forces after the regeneration with bone graft could be crucial to reduce root resorptions and to increase bone formation. Nevertheless more studies in humans are necessary to confirm these results and to have information about long-term effects. Most used bone grafts for alveolar regeneration are Bio-Oss and synthetic bone, however, in cases of several bone defects, autologous bone is the “gold standard”. Continuous and light orthodontic forces are most recommended.
