| Abstract: | Objective To investigate the clinical results of crown lengthening combined with caryopivot crown restoration in treating maxillary anterior teeth introversion.Methods Because of maxillary anterior teeth introversion,gingival line low,or gummy smile,78 teeth in 20 patients who wanted to improve gingival aesthetics were performed with crown lengthening combined with caryopivot crown restoration.Through two years observation,compared the changes of the plaque index,sulcus bleeding index,probing depth and mobility between preoperation and postoperation.Results Plaque index,sulcus bleeding index,probing depth and mobility of the teeth after operation were all better than preoperation significantly(P<0.05).Conclusion The clinical effects of crown lengthening combined with caryopivot crown restoration on treating maxillary anterior teeth introversion are very good in the near future. |
