Abstract：Objective To investigate the effects of magnetic attachments on masticatory efficiency and retention func-tion in restoration with mandibular implant-supported overdenture.Methods A total of 130 patients with mandibular edentu-lous jaw treated in the Department of Stomatology from September 2019 to January 2021 were selected and divided into two groups according to the different restoration and fixation methods of mandibular implant-supported overdenture.Sixty-five pa-tients treated with magnetic attachment were enrolled as the magnetic group and 65 patients treated with ball-cap attachment were enrolled as the ball-cap group.The masticatory efficiency,self-satisfaction,soft tissue health around the implant,im-plant bone absorption and aesthetic repair effect were compared between the two groups.Results At 6 and 12 months after overdenture restoration,there was no significant intragroup or intergroup difference in masticatory efficiency in the two groups(P＞0.05).At 12 months after the overdenture restoration,the scores of comfort and retention function of the magnetic group were higher than those of the ball-cap group(P＜0.05).At 12 months after overdenture restoration,periodontal pocket pro-bing depth and gingival index scores in the magnetic group were lower than those in the ball-cap group(P＜0.05).At 6 months and 12 months after overdenture restoration,there was no significant intragroup or intergroup difference in implant bone absorption(P＞0.05).At 12 months after the overdenture restoration,satisfaction rate of the facial morphology,no staining rate and edge suitability rate in the magnetic group were higher than those in the ball-cap group(P＜0.05).Conclusion The application of magnetic attachment in restoration with mandibular implant-supported overdenture has good effects,good masticatory efficiency and retention function,and good soft tissue health around the implant,without causing bone resorption,and with good safety and aesthetic effects,and high patient satisfaction.
