摘要
目的:观察烤瓷冠修复前行高频电刀龈成形术对基牙牙周组织的影响。方法:收集需行高频电刀龈成形术后再作烤瓷冠修复的患者91例135颗牙,修复后1年复查牙周情况,分析患者术后1年牙龈成形效果、牙龈指数、牙菌斑指数、牙周探诊深度、牙齿动度。结果:龈成形术后烤瓷冠修复1年5．9％患者出现牙龈增生或退缩;牙龈指数轻度上升,有显著性差异;菌斑指数、牙周探诊深度、牙齿动度无明显差异。结论:高频电刀龈成形术对其后烤瓷冠修复基牙牙龈成形效果良好,对基牙牙周健康无明显不良影响。
Objective ： To analyze the effects of electrotome gingivoplasty on periodontal health of the abutment teeth repaired by using porcelain- fused- to- metal （PFM） crowns after electrotome gingivoplasty. Methods： The information of 135 teeth from 91 patients was collected. Before these teeth were repaired with PFM crowns, electrotome gingivoplasty had been operated. One year after repair, the periodontal health was assessed and the effects of gingivoplasty on gingival index （GI）, plaque index （PLI）, probing depth （PD） and teeth mobility were analyzed. Results： After one year, the gingive of 5.9% cases developed recession or hyperplasia. The GI increased and showed significant difference between pre -and post -restoration, however, the PLI , PD and teeth mobility showed no singnificant differences. Conclusion： Electrotome gingivoplasty have no negative effects on periodontal health of the abutment teeth with PFM crowns.
