摘　　要：目的对上颌前牙区临床牙冠过短的患牙用水激光行牙冠延长术术后效果观察。方法选择需要前牙美学区延长的20位患者,随机分为2组,各10位30颗患牙,试验组行上颌前牙美学区冠延长,采用水激光行牙龈切除即刻不翻瓣骨修整。对照组行上颌前牙美学区冠延长,采用刀片行牙龈切除即刻翻瓣骨修整。检测术前、术后2周、4周、2个月、6个月龈缘位置,龈沟出血指数,探诊深度。结果试验组龈缘位置、探诊深度的稳定性在4周内与对照组存在显著差异(P<0.05),4周后无明显差异。龈沟出血指数2组无明显差异。结论水激光在美容区牙冠延长术中能较快获得龈缘的稳定性以及正常的牙周附着。Objective To evaluate the clinical effects of crown lengthening in maxillary anterior teeth whose crowns were too short clinically with waterlase Methods We overviewed 120 teeth from 20 patients who underwent crown lengthening surgery in aesthetic areas of anterior teeth. Sixty teeth from 10 patients were done with waterlase - assisted gingivectomy and instant flapless bone trimming. Sixty teeth from the other 10 patients were done with gingivectomy with blade and instant flap surgery with bone trimming. The position of gingival margin, sulcus bleeding index （SBI）and probing depth （PD） were measured before the surgery as well as 2 weeks ,4 weeks, 2 months and 6 months after surgery. Results The stability of gingival margin and PD had significant difference between 2 groups within four weeks （P 〈 0.05 ） , but 4 weeks later, there was no significant difference. There was no significant difference in SBI between 2 groups. Conclusions Waterlase can achieve stability of gingival margin and gain normal periodontal attachment faster in crown lengthening surgery in aesthetic area.
