Abstract：AIM:To evaluate the clinical effects of surgical crown lengthening in the re-treatment of anteri-or teeth restoration.METHODS:45 patients complaining of gum edema after anterior teeth restoration (72 teeth) were included.After baseline examination,the previous ceramic crowns were removed,root canal therapy and perio-dontal therapy were done as indicated.Then,surgical crown lengthening was performed.8 weeks after crown lengthe-ning,permanent restorations were made.Sulcus bleeding index (SBI)and probing depth (PD)were recorded at 8week,6month,1year and 2 year follow-up.RESULTS:Significantly lower values of SBI and PD were found at all time points post crown lengthening as compared with that of pre-surgery (P<0.05 ).No significant difference of the effectiveness was found among all time points 8week after re-treatment(P>0.05 ).CONCLUSION:Surgical crown lengthening is an effective method for the re-therapy of anterior teeth restoration.
