摘要
目的分析微种植体支抗植入位点对成人露龈笑矫治效果的影响。方法选取2019年1月至2022年1月行微种植体支抗钉植入的上颌前部牙槽骨垂直向发育过度患者118例,按照随机数字表法平均分成2组,中切牙间组(上颌中切牙间植入)脱落3例,侧切牙间组(上颌中切牙和侧切牙间植入)脱落2例,最终纳入中切牙间组56例和侧切牙间组57例。术后12个月比较2组临床矫治效果。结果2组治疗前后垂直露龈量、前牙覆颌差值比较无差异(P>0.05)。中切牙间组治疗前后上颌中切牙-前颅底平面角、上颌中切牙-颏垂线距离差值均大于侧切牙间组(P<0.05)。2组治疗前后蝶鞍中心-鼻根点-上齿槽座点构成的角、蝶鞍中心-鼻根点-下齿槽座点构成的角、上齿槽座点-鼻根点-下齿槽座点构成的角、上颌第一磨牙-前颅底平面角、上颌中切牙-腭平面距离、上颌第一磨牙与颏垂线距离、上颌第一磨牙与腭平面距离差值比较无差异(P>0.05)。中切牙间组治疗前后牙根长度差值大于侧切牙间组(P<0.05)。2组治疗前后中切牙牙体长度、牙周袋探诊深度、牙龈指数差值比较无差异(P>0.05)。结论不同部位植入微种植体支抗钉压低上颌前牙均能改善露龈笑的临床症状,但从上颌中切牙与侧切牙之间植入上颌前牙牙根吸收更少。
Objective To analyze the effect of implantation site for microimplant anchorage(MIA)on the correction of adult gingival smile.Methods A total of 118 patients with vertical hyperplasia of anterior maxillary alveolar bone who underwent MIA implantation from January 2019 to January 2022 were selected.The patients were divided into two groups according to the random number table method,among whom there were 3 cases of detachment in the intercentral incisor group(implanted between maxillary central incisors)and 2 cases of detachment in the interlateral incisor group(implanted between maxillary central incisor and lateral incisor).Finally,56 cases in intercentral incisor group and 57 cases in interlateral incisor group were included.The clinical orthodontic effect of the two groups was compared at 12 months after operation.Results There was no significant difference in vertical gingival volume and anterior overbite difference between the two groups before and after treatment(P>0.05).The upper incisor and sella nasion plane(UI-SN)and upper incisor-true horizontal plane(UI-T)before and after treatment in intercentral incisor group were higher than those in interlateral incisor group(P<0.05).There was no significant difference in sella-nasion-A point angle(SNA),sella-nasion-B point angle(SNB),A point-nasion-B point angle(ANB),upper first permanent molar-sella nasion plane(U6-SN),upper incisor-palatal plane(UI-PP),upper first permanent molar-true horizontal plane(U6-T)and upper first permanent molar-palatal plane(U6-PP)between the two groups before and after treatment(P>0.05).The difference value of root length before and after treatment in intercentral incisor group was greater than that in interlateral incisor group(P<0.05).There were no significant differences in the length of central incisors,the probing depth of periodontal pocket,and gingival index between the two groups before and after treatment(P>0.05).Conclusion The clinical symptoms of gingival smile could be improved when the maxillary anterior teeth were depressed by microimplants in different parts,but the root resorption of the anterior teeth implanted between the central and lateral incisors was less.
