成人重度牙周病患者应用隐形矫治器对牙槽骨改建的影响

Effects of Invisible Appliance on Alveolar Bone Remodeling in Adult Patients with Severe Periodontal Disease

目的:探究成人重度牙周病患者应用隐形矫治器矫治对牙槽骨改建的影响。方法:选取2020年1月-2021年6月河北中石油中心医院口腔科采用隐形矫治器矫治的重度牙周病患者82例,观察患者治疗前后上颌切牙位置、唇倾度、牙槽骨高度及牙槽骨密度变化,记录患者牙周健康状况。结果:患者治疗后的牙齿松动度较治疗前明显减轻,差异有统计学意义(P<0.05);患者治疗前后CEJ-BM-La、CEJ-BM-Li水平比较,差异无统计学意义(P>0.05),治疗后,患者的唇倾度、Cu-PP、Cu-PL、Aa-PP均低于治疗前,Aa-PL高于治疗前,差异有统计学意义(P<0.05);治疗后,患者的唇侧、舌侧、近中、远中牙槽骨高度及平均牙槽骨高度均高于治疗前(P<0.05);治疗后,患者牙槽嵴顶区舌侧的牙槽骨密度低于治疗前(P<0.05),而治疗后患者的牙槽嵴顶区唇侧、根中区唇侧、根中区舌侧、根尖区唇侧、根尖区舌侧与治疗前比较,差异均无统计学意义(P>0.05);治疗后,患者的牙槽骨吸收情况较治疗前减轻,差异有统计学意义(P<0.05);治疗后,患者的PLI低于治疗前(P<0.05),治疗后的GI、PD、SBI与治疗前比较,差异无统计学意义(P>0.05)。结论:成人重度牙周病患者牙槽骨应用隐形矫治器可达到满意效果,能有效改建牙槽骨,并改善口腔菌斑情况,患者需注意定时进行复查,关注牙槽骨状态变化及口腔健康的维护。

Objective To explore the effects of invisible appliance on alveolar bone remodeling in adult patients with severe periodontal disease.Methods A total of 82 patients with severe periodontal disease who were treated with invisible appliance in Stomatology Department of Hebei Petro China Central Hospital were enrolled between January 2020 and June 2021.The changes of maxillary incisors position,lip inclination,alveolar bone height and density before and after treatment were observed.The periodontal health status of patients was recorded.Results After treatment,tooth loosening was significantly reduced compared with that before treatment,the difference was statistically significant(P<0.05).Before and after treatment,there was no significant difference in CEJ-BM-La or CEJ-BM-Li(P>0.05).After treatment,lip inclination,Cu-PP,Cu-PL and Aa-PP were decreased,while Aa-PL was increased(P<0.05).After treatment,alveolar bone height in labial,lingual,mesial and distal sites,and average alveolar bone height were higher than those before treatment.After treatment,alveolar bone density of lingual site in alveolar ridge crest was decreased(P<0.05),but there was no significant difference in alveolar bone density of labial site in alveolar ridge crest,labial site in central root,lingual site in central root,labial site in apical area and lingual site in apical area before and after treatment(P>0.05).After treatment,alveolar bone resorption was relieved compared with that before treatment,the difference was statistically significant(P<0.05).After treatment,PLI was decreased(P<0.05).Before and after treatment,there was no significant difference in GI,PD or SBI(P>0.05).Conclusion The application effect of invisible appliance is satisfied in alveolar bone of adult patients with severe periodontal disease,which can effectively reconstruct alveolar bone and improve oral plaque condition.It is necessary to conduct regular reexamination,pay attentions to changes of alveolar bone status and keep oral health.
