目的对比分析传统支抗与微种植体支抗对口腔正畸患者正畸效果及X线头影测量指标的影响。方法选取2021年1月至2023年6月我院收治的80例口腔正畸患者作为研究对象,随机分为A组(n=40)和B组(n=40)。A组采用微种植体支抗矫治,B组采用传统支...目的对比分析传统支抗与微种植体支抗对口腔正畸患者正畸效果及X线头影测量指标的影响。方法选取2021年1月至2023年6月我院收治的80例口腔正畸患者作为研究对象,随机分为A组(n=40)和B组(n=40)。A组采用微种植体支抗矫治,B组采用传统支抗矫治。对比两组的正畸效果,矫治前及矫治18个月后的X线头影测量指标[上下齿槽座(A point-Nasion-B,ANB)角、下齿槽座(Sella-Nasion-B,SNB)角、下中切牙-下颌平面(lower incisor to mandibular plane,L1-MP)角、上下中切牙(upper incisor to lower incisor,U1-L1)角]、牙齿功能,以及并发症发生率。结果A组的磨牙移位、上中切牙凸距差、上中切牙倾斜差均较B组低,矫正时间、拔牙间隙闭合时间均较B组短(P<0.05)。矫治18个月后,A组的ANB角、SNB角、L1-MP角均较B组小,U1-L1角较B组大(P<0.05)。矫治18个月后,A组的吞咽、咀嚼、牙齿咬合、口语表达评分均较B组高(P<0.05)。A组的并发症总发生率为2.50%,较B组的20.00%低(P<0.05)。结论相较于传统支抗矫治,微种植体支抗矫治可进一步提升正畸效果,改善正畸患者的面型与牙齿功能,降低患者并发症发生风险。展开更多

Therefore, the aim of this clinical investigation was to analyze the relationship between sleep bruxism and several functional and occlusal parameters. The null hypothesis of this study was that there would be no differences among sleep bruxism subjects and non-sleep bruxism controls regarding several functional and occlusal parameters. Fifty-eight sleep bruxism subjects and 31 controls participated in this study. The diagnosis sleep bruxism was based on clinical criteria of the American Academy of Sleep Medicine. Sixteen functional and occlusal parameters were recorded clinically or from dental study casts. Similar to the recently published retrospective pilot study, with a mean slide of 0.77 mm （s.d., 0.69 mm） in the sleep bruxism group and a mean slide of 0.4 mm （s.d., 0.57 mm） in the control group, the evaluation of the mean comparison between the two groups demonstrated a larger slide from centric occlusion to maximum intercuspation in sleep bruxism subjects （Mann-Whitney U-test; P=O.O08）. However, following Bonferroni adjustment, none of the 16 occlusal and functional variables differed significantly between the sleep bruxism subjects and the non-sleep bruxism controls. The present study shows that the occlusal and functional parameters evaluated do not differ between sleep bruxism subjects and non-sleep bruxism subjects. However, as the literature reveals a possible association between bruxism and certain subgroups of temporomandibular disorders, it appears advisable to incorporate the individual adaptive caoacitv of the stomatognathic svstem into future investigations.展开更多
