【摘要】：目的:研究超薄贴面修复变异前牙的临床效果。方法:选择要求对先天性牙体形态发育异常(锥形牙及过小牙)的前牙进行美学修复的患者41例共67颗变异前牙,确认患牙牙髓、牙周健康后行不备牙或少备牙(0.3~0.5mm)超薄贴面修复,根据改良的美国公共卫生署评价标准(USPHS),由2位医师分别评价修复后0.5、1、2、3、4年的美学修复效果。结果:在0.5、1、2、3、4年的追踪研究中,分别有0(0)、1(1)、3(6)、7(12)、11(18)例患者(贴面)失访,患者满意度分别为100%、100%、98%、96%、91%。修复体完整性、颜色、边缘美学效果(密合度及是否着色)、贴面形态、半透明度、牙龈指数、牙齿敏感性、继发龋、患者满意度等方面,经4年的追踪检查,均取得了满意的效果。结论:在严重控制适应症和告知患者注意事项及使用方法的情况下,微创超薄贴面修复变异前牙可取得良好的修复效果,值得临床推广应用。
[Abstract]:Objective: to study the clinical effect of ultra-thin veneer in repairing variant anterior teeth. Methods: a total of 67 variant anterior teeth were selected from 41 patients with congenital abnormal tooth morphology (conical teeth and small teeth), and the pulp of the affected teeth was confirmed. Ultra-thin veneer restoration of unprepared or less prepared teeth (0.3~0.5mm) was performed after periodontal health. According to the improved US Public Health Agency evaluation standard (USPHS), two doctors evaluated the aesthetic restoration effect of 0.5, 1, 2, 3 and 4 years after restoration. Results: in 0.5, 1, 2, 3 and 4 years follow-up study, 0 (0), 1 (1), 3 (6), 7 (12), 11 (18) patients (veneer) lost follow-up, the patient satisfaction was 100%, 100%, 98%, 96%, respectively. 91%. Restoration integrity, color, edge aesthetic effect (closeness and coloring), veneer shape, translucency, gum index, tooth sensitivity, secondary caries, patient satisfaction, etc., after 4 years of follow-up examination, Satisfactory results have been obtained. Conclusion: under the condition of serious control of indications and informing patients of matters needing attention and using methods, minimally invasive ultra-thin veneer repair of variant anterior teeth can achieve good repair effect, which is worthy of clinical application.
