Abstract:
ObjectiveThis?study?aims?to?analyze?the?long-term?stability?of?the?anterior?teeth?and?hard?tissue?of?skeletal?class?Ⅲ?malocclusion?after?a?three-year?orthodontic?surgery?by?systematic?review.?Methods???All?studies?about?skeletal?class?Ⅲ?malocclusion?with?orthodontic-surgery?were?searched?by?computer-based?retrieval?and?manual?retrieval;?the?deadline?is?December?2013.?The?literature,?filtered?according?to?the?inclusion?criteria?and?exclusion?criteria,?was?performed?with?quality?assessment.?The?same?indicators?of?the?anterior?location?and?hard?tissue?stability?were?combined?and?evaluated?with?meta-analysis?and?descriptive?analysis?by?Rev?Man5.2.?Results???Four?before-and-after?comparison?study?articles?with?180?cases?were?included.?The?grades?of?the?four?literature?evaluation?were?A.?The?meta-analysis?results?showed?that?comparing?the?three-year?post-orthodontic-surgery?and?post-orthodontic-surgery,?the?total?weighted?mean?difference?(WMD)?of?U1-SN?was?4.29?(P<0.05);?the?WMD?of?L1-MP,?OB,?OJ,?SNA,?SNB,?ANB,?and?MP-SN?were?-1.58,?0,?-0.41,?-0.58,?0.25,?-0.70,?and?0.39,?respectively?(P>0.05).?The?measurement?methods?of?A?and?B?point?position?were?different,?hence?the?qualitative?description?were?as?follows:?point?A?remained?at?a?relatively?stable?position,?and?point?B?had?some?replacement?compared?with?post-operative?(P<0.05).?Conclusion???To?the?skeletal?class?Ⅲ?malocclusion?after?three-year?orthodontic-surgery,?the?position?of?the?lower?anterior?teeth?could?be?kept?stable,?as?well?as?the?overbite?and?the?overjet?of?the?anterior?teeth;?only?the?upper?inci-sor?has?a?lip-inclined?relapse.?The?maxillary?could?also?be?kept?stable,?and?the?mandibular?had?a?little?relapse.
