Abstract:
Objective To analyze the application of root angioplasty in the crown lengthening surgery. Methods A total of 80 patients that corresponding to criteria from January 2013 to December 2015 in repair outpatients of our hospital were selected and received retrospec-tive study,and they were randomly divided into the observation group and the control group according to different surgical methods with 40 ca-ses in each group. The observation group was given root angioplasty and crown lengthening surgery,while the control group was only given crown lengthening surgery. Check-up was performed at 6 weeks postoperatively and 3 weeks after restoration,the condition of root surface cov-ered by the gum,the condition of gingival recession of the restoration and the subjective satisfaction of the patients were observed. Results The average coverage of the observation group was 91. 3%,which was significantly more than 55. 3% of the control group (P<0. 05). The a-mount of the gum covering of the observation group was (3.1 ±1.3)mm,which was significantly larger than (1.9 ±1.0)mm of the control group(P<0. 05). Conclusion Root angioplasty can guarantee blood supply,reduce the damage,but the indication range is small,and it is influenced by many factors,and needs to incorporate the ideas of all sides when used in clinic.
