微种植体支抗辅助上颌快速扩弓对Ⅲ类错(牙合)畸形患者疗效及美学效果的影响OA

Objective To investigate the efficacy of Mini-implant Assisted Rapid Maxillary Expansion(MARME)in patients with Class Ⅲ malocclusion and its impact on upper airway volume and aesthetic outcomes.Methods A retrospective study was conducted on 100 patients with Class Ⅲ malocclusion who visited the stomatology department of the hospital from October 2021 to October 2023.The patients were divided into the MARME group(treated with MARME)and the rapid maxillary expansion(RME)group(treated with RME),with 50 patients in each group.The upper airway volume,airway resistance(Raw),facial aesthetic outcomes,clinical efficacy,incidence of adverse reactions during treatment,and patient satisfaction were compared between the two groups before and after treatment.Results After treatment,the nasopharyngeal airway volume,oropharyngeal airway volume,hypopharyngeal airway volume,and total upper airway volume increased in both groups,with the MARME group showing higher values than the RME group(P＜0.05).There was no significant difference in laryngopharyngeal airway volume between the two groups before and after treatment(P＞0.05).The Raw decreased in both groups,with the MARME group having lower values than the RME group(P＜0.05).The upper alveolar Angle(SNA)and upper and lower alveolar Angle(ANB)increased in both groups,with the MARME group was higher than the RME group(P＜0.05).The lower alveolar Angle(SNB)decreased in both groups,with the MARME group was lower than the RME group(P＜0.05).The clinical efficacy and patient satisfaction were higher in the MARME group than in the RME group,and the incidence of adverse reactions was lower in the MARME group(P＜0.05).Conclusion MARME technology for the treatment of patients with Class Ⅲ malocclusion can increase upper airway volume,reduce airway resistance,improve facial aesthetics,enhance clinical efficacy and patient satisfaction,and decrease the incidence of adverse reactions.
