自玻璃离子粘固剂问世以来,在国内外口腔临床上得到了广泛的应用,但鉴于玻璃离子粘固剂的耐磨性及抗压性能与银汞合金相比仍有差距,为保持银汞合金的优点,且防止汞污染,我科与上海青浦齿科材料厂及轻工业研究所共同研制和开发了SGI—Ⅱ型银合金粉玻璃离子粘固剂(以下简称银玻璃)。经二年多的临床应用,疗效较好,现对门诊病例中随机复查的120名病人的治疗结果作分析,并对材料的特点和应用要点等进行探讨。 材料和方法 一、临床资料 门诊病人中经银玻璃治疗超过二年的患者120名,修复166颗牙。修复类型Ⅰ类:8例,Ⅱ类:43例,复合洞型:79例,残冠:36 例。其中男性63名,女性57名。年龄分布为: 21岁～30岁 14名,31岁～40岁 31名,41 岁～50岁45名,51岁～60岁12名,61岁～ 70岁18名,最大年龄66岁,最小年龄21 岁,平均年龄43岁。
Since the advent of glass ionomer cement, oral clinics at home and abroad have been widely used, but given the wear resistance and compressive properties of glass ionomer cement compared with the amalgam is still a gap, in order to maintain amalgam Alloy and mercury pollution prevention, our department and Shanghai Qingpu Dental Materials Factory and Light Industry Research Institute jointly developed and developed SGI-Ⅱ type silver alloy powder glass ionomer cement (hereinafter referred to as silver glass). After more than two years of clinical application, the curative effect is better, now the outpatient cases random review of the results of the treatment of 120 patients for analysis, and the characteristics of the material and application points are discussed. Materials and methods First, the clinical data Out-patient patients treated by silver glass for more than two years 120 patients, repair 166 teeth. Type I repair: 8 cases, type II: 43 cases, composite cavity: 79 cases, residual crown: 36 cases. 63 males and 57 females. Age distribution: 21 years old to 30 years old 14, 31 years old to 40 years old 31, 41 years old to 50 years old 45, 51 years old to 60 years old 12, 61 years old to 70 years old 18, the maximum age of 66 years old, the smallest Age 21 years old, average age 43 years old.
