摘要
目的:观察改良牙冠延长术的临床疗效。方法:对31例患者的31个牙体缺损延伸至龈下3.0 mm以上患牙行改良牙冠延长术,术后1、3、9、15个月随访,比较患牙术前后的菌斑指数(PLI)、出血指数(BI)、牙周探诊深度(PD)和松动度(TM)。结果:31个患牙术后1,3,9,15个月的PD、BI、PLI、TM较术前改善明显(均为P<0.05);术后无松动、牙龈健康、龈缘协调;修复体稳定;患者自诉功能良好,疗效满意。结论:改良牙冠延长术可作为常规牙冠延长术不足的一种弥补。
AIM: To observe the clinical effects of modified crown lengthening surgery. METHODS:Mod- ified crown lengthening was performed on 31 teeth with crown defects involved more than 3 mm subgingivally. Plaque index (PLI), bleeding index (BI), probing depth (PD) and tooth mobility (TM) were measured before and 1, 3, 9 and 15 months after operation at follow-up. RESULTS: PLI, BI, PD and TM were significantly decreased at 1, 3, 9 and 15 months after modified crown lengthening (P 〈 0.05 ). Gingival health and gingival margin coordination were im- proved, prosthetic replacements were stable in all patienrs. CONCLUSION:Modified surgical crown lengthening is an effective surgical method for conventional crown lengthening.
