单侧拔牙矫正牙列拥挤的探讨格床医学.2oo9年8月第1卷第8期医学信息单侧拔牙矫正牙列拥挤的探讨涂文【摘要1目的:探讨并分析具有特殊适应症的患者,上下颌单侧拔牙矫治轻中度牙列拥挤与上下颌双侧对称性拔牙矫治轻中度牙列拥挤的疗效差异.方法:回顾性分析2006年12月～2008年12月期间我院28例上下颌单侧拔牙矫治轻中度牙列拥挤(实验组)和25例上下颌双侧对称性拔牙矫治轻中度牙列拥挤(对照组)患者的一临床资料,比较两组间在术后牙弓对称性方面的差异.实验组在选择病历时要求其上下颌轻中度牙列拥挤病例的面型较好,拥挤集中于牙弓一侧,拥挤度在5～9mm之间.结果:于治疗后的24个月内让患者定期回院复查,发现采用上下颌单侧拔牙矫治轻中度牙列拥挤的28例患者拥挤全部解除,其上下颌中线无明显偏斜,上下牙列尖窝关系咬合紧密.25例上下颌双侧对称性拔牙矫治轻中度牙列拥挤同样结果.两种拔牙方式矫治轻中度牙列拥挤,在牙弓对称性方面的差异无显着性统计学意义(P》0.05).结论:本项研究证明,上下颌单侧拔牙能成功地矫治轻中度牙列拥挤且拥挤集中于牙弓一侧的患者,具有简化疗程和减少拔牙的优点,是一项可推广的技术.【关键词】拔牙;矫正;牙列拥挤CorrectionofunilateralextractionofcrowdingTUW[Abstract]Ohjective:Toinvestigateandanalyzethepatientswithspecialindications,extractionorthodontictreatmentonmandibularunilatera1mildtomoderatemandibularcrowdingwithbilateralsymmetryextractionorthodontictreatmentofmildtomoderatecrowdingeffectofthedifference.Methods:RetrospectiveanalysisinDecember2006—2008duringtheyearsinourhospitalinDecemberon28casesofunilatera1extractionofmandibularcrowdingwithmildtomoderatetreatment(experimenta1group)and25casesofmandibularbilateralsymmetryextractionorthodontictreatmentinlightdegreeofcrowding(controlgroup)inpatientswithclinicaldata,comparisonbetweenthetwogroupsinpostoperativedentalarchsymmetrydifferences.Medica1recordsinthechoiceoftheexperimentalgroupaskeditsupperand1owercasesofmildtomoderatecrowdingofthefaceisbetterfocusedonthearchsideofovercrowding,congestion5mm～9mminbetween.Results:Aftertreatmentof24monthstoallowhospita1patientsbacktoregularreviewandfoundthattheuseofextractionOrthodontictreatmentonmandibularunilat—eralmildtomoderatecrowdingofthe28casesofcongestionofal1theliftingofpatients,theupperandlowermidlinewasnosig—nificantdeviation,upperandlowerWaterloosharpocctusaldentitioncloserelationship.On25casesofmandibularbilateralsym-metryextractionorthodontictreatmentwithmildtomoderatecrowdingthesameresult.Twoextractionmethodscorrectingmildtomoderatecrowdinginthedenta1archsymmetryaspectsofthedifferencewasnotsignificantstatisticallysignificant(P》O.O5).Conclusion:ThisstudyshowsthattheextractionofmandibularunilateralSUCCessincorrectingmildtomoderatecrowdingandcongestionconcentratedonthesideofthepatientdentalarch,withasimplifiedtreatmentandreducetheadvantageofextractionisareplicabletechnology.[Keywords]toothextraction;correction;toothcrowding【】R78.211【文献标识码】A【11006～1959(2009)08—0082—02牙列的轻,中度拥挤在牙齿畸形中较为常见,其不仅可影响美观,还可因牙齿自洁作用较差而导致发生牙体或牙周疾患,因此,应及时尽早解决牙列拥挤.近些年随着生活水平的提高,人们越来越多地认识到牙列拥挤给牙齿带来的危害,所以拔值为正常值的100~1000倍[3].本组资料显示在感染性腹泻中无论是细菌感染还是病毒感染,CRP均较正常对照组增高,但病毒感染组与细菌感染组问比较CRP差异无显着性.提示:在感染性腹泻泻患儿中,CRP不能用于鉴别细菌感染或病毒感染,而应根据临床表现,大便性状,大便常规及细菌培养,病毒检测等综合分析判断.CRP水平与感染严重程度密切相关,其浓度上升是各种原因引起的炎症和组织损伤的灵敏指标].CR...
