隐形矫治器对成人错颌畸形患者ABO-OGS评分及牙周指数的影响

Effect of Invisible Appliance on ABO-OGS Score and Periodontal Index of Adult Malocclusion Patients

目的探讨隐形矫治器对成人错颌畸形患者基于美国正畸学会客观评分系统(ABO-OGS)评分及牙周指数的影响。方法选取南阳市口腔医院2017年12月至2019年12月收治的80例成人错颌畸形患者,按照随机数字表法分组,各40例。对照组给予直丝弓矫治器(SWA)治疗,试验组给予隐形矫治器治疗。统计两组ABO-OGS评分、口腔咬合功能、牙周指数[菌斑指数(PLI)、牙周探诊深度(PD)、牙龈指数(GI)、龈沟出血指数(SBI)]、龈沟液炎症介质[白细胞介素-6(IL-6)、白细胞介素-1β(IL-1β)、前列腺素E(PGE)]、满意度、不良事件发生率。结果矫治后两组ABO-OGS评分比较,差异无统计学意义(P>0.05);矫治后试验组咀嚼次数、咀嚼效能、最大咬合时间、最大咬合力均高于对照组,差异有统计学意义(P<0.05);矫治后试验组PLI、PD、SBI、GI低于对照组,差异有统计学意义(P<0.05);矫治后试验组龈沟液IL-6、IL-1β、PGE水平低于对照组,差异有统计学意义(P<0.05);试验组患者满意度高于对照组,差异有统计学意义(P<0.05);两组不良事件发生率比较,差异无统计学意义(P>0.05)。结论隐形矫治器应用于成人错颌畸形患者可取得良好矫治效果,改善牙周指数,下调龈沟液炎症介质,提高满意度。

Objective To investigate the effect of the invisible appliances on the periodontal index and American Society of Orthodontics.Methods The 80 adult patients with malocclusion admitted to Nanyang Stomatological Hospital from December 2017 to December 2019 were selected and divided into groups according to the random number table method,with 40 cases in each group.The control group was treated with a straight wire arch appliance(SWA),and the test group was treated with an invisible appliance.The ABO-OGS score,oral occlusal function,periodontal index[plaque index(PLI),periodontal probing depth(PD),gingival index(GI),gingival crevicular bleeding index(SBI)],inflammatory mediators of gingival crevicular fluid[interleukin-6(IL-6),interleukin-1β(IL-1β),prostaglandin E(PGE)],satisfaction,and incidence of adverse events were statistically analyzed between the two groups.Results There was no significant difference in ABO-OGS scores between the two groups after correction(P>0.05);After treatment,the masticatory times,masticatory efficacy,maximum occlusal time,and maximum bite force of the test group were higher than those of the control group,and the differences were statistically significant(P<0.05);After treatment,PLI,PD,GI and SBI in the test group were lower than those in the control group,and the differences were statistically significant(P<0.05);After treatment,the level of IL-6,IL-1β,and PGEin the gingival crevicular fluid of the test group was lower than that of the control group,and the differences were statistically significant(P<0.05);The satisfaction of patients in the test group was higher than that in the control group,and the differences were statistically significant(P<0.05);There was no significant difference in the incidence of adverse events between the two groups(P>0.05).Conclusion The application of an invisible appliances in adult malocclusion patients can achieve the good orthodontic effect,improve periodontal index,reduce inflammatory mediators in gingival crevicular fluid,and improve satisfaction.
