Background and aim: the purpose of present study was evaluate changes in alveolar bone in both jaws. Method: all articles published in international databases such as PubMed, Scopus, Science Direct, and Embase over the last five years between 2016 and September 2021 included. Google Scholar search engine was used. Data analysis was performed using STATA.V16 software. Result: In the initial search, 1552 studies were identified; full text of 38 articles was reviewed; finally 14 articles entered the analysis. Mean differences of Labial and Lingual alveolar bone height between post and pretreatment was (MD, 0.40 95% CI 0.32, 0.49) (MD, 0.31 95% CI 0.20, 0.42). Mean differences of alveolar bone height of mandibular extraction treatment between post and pre-treatment was 0.83 (MD, 0.83 95% CI 0.56, 1.10). Conclusion: Meta-analysis showed a decrease in alveolar bone height and thickness in both labial and lingual movement of anterior teeth
