摘要
目的:探讨龈-牙性露龈笑患者行微创牙冠延长术后的美学疗效。方法:选取18例龈-牙性露龈笑患者共94颗患牙,行微创牙冠延长术;分析其临床疗效,并应用菌斑指数(plaque index,PLI)、牙松动度(tooth mobility,MOB)评价牙龈、牙周情况,以及微笑线水平评价患牙治疗前后的美观效果,并通过视觉模拟评分法评价患者治疗前后的满意度。结果:微创牙冠延长术术后1周PLI增高,但经口腔卫生指导后,术后8周、6个月PLI降低。术后1周MOB有加大趋势,于术后8周趋于稳定。患者的微笑线水平术后均达Ⅱ,Ⅲ类标准,患者对前牙牙龈的美学效果较为满意。结论:通过适应症的正确选择,手术的精细操作及正规的口腔卫生保健,微创牙冠延长术可获得满意临床疗效。
Objective： To evaluate the aesthetic effects of minimally invasive crown lengthening surgery on the pa- tients with bare - gummed smile. Methods： The patients who suffered from gummy smile and of course underwent a minimally invasive crown lengthening surgery were chosen. The plaque index（PLI） and the tooth mobility （ MOB ）were used to evaluate the gingival and periodontal conditions. The aesthetic effects of the treated teeth were evaluated with the smile line level. Vis- ual analogue scale（VAS） was used to examine patientg satisfaction degree before and after treatment. Results：One week after minimally invasive crown lengthening, the PLI was increased. But after oral hygiene instruction, PLI were decreased at 8 weeks and 6 months after surgery, respectively. The tooth mobility had a growing trend at 1 week after surgery and stabilized at 8 weeks after operation. The patients were satisfied with the gingival aesthetic effect of the maxillary anterior teeth, with the patient＇s smile line reaching the class Ⅱ and class Ⅲ standards. Conclusion：Patients could attain satisfactory clinical effects using the minimally invasive crown lengthening surgery, combined with the correct selection of indications, delicate operation and regular oral health care.
