摘要
目的研究镀金对牙科含钛合金材料在人工唾液中金属铍离子析出的影响。方法将测试组分为4组:普通含钛合金烤瓷全冠组(对照组)、打磨后含钛合金烤瓷全冠组(打磨组)、喷砂镀金含钛合金烤瓷全冠组(镀金组)及喷砂镀金加时50%含钛合金烤瓷全冠组(镀金加时50%组)。采用电感耦合等离子体发射光谱法(ICP-AES),测试在人工唾液中1月末、3月末、6月末时铍离子的浓度,比较不同处理因素对铍离子析出量的影响以及同一处理因素下铍离子析出速率的改变。结果1在不同处理方法相同时间点下,铍离子析出总量为打磨组>对照组>镀金组>镀金加时50%组,且差异有统计学意义(P<0.01)。2在同一处理因素不同时间点下,铍离子的析出总量随着浸泡时间的延长而增加,呈现时间效应关系;铍离子的析出速率随着浸泡时间的延长而降低。结论含钛合金烤瓷全冠表面镀金处理能降低铍离子的析出量,从而提高含钛合金烤瓷全冠的生物相容性。
Objective To research the effect of gilming technique on the element release from Vera Bond Ti alloy exposed to artificial saliva.Methods To divided experimental group into 4 groups：common used Ti porcelain crown（controlling group,A1）,polished Ti porcelain crown（polished group,A2）,gilded Ti porcelain crown（gold-plating group,A3）,gilded Ti porcelain crown prolonged 50%（gold-plating prolonged 50% group,A4）.T measure the quantity of beryllium ion in artificial saliva after 1 month,3 months and 6 months by means of ICP-AES.So the efect of released beryllium ion with different treatments and the role of different times with the same treatment were compared.Results The quantity of released beryllium ion was statistic significant among different treatments.The quantity of released beryllium ion was gradually increased with the same treatment.The speed of released beryllium ion was gradually decreased with the same treatment.Conclusion The gilding treatment can decrease the quantity of beryllium ion which releasedfrom Ti porcelain crown,and improve the biocompatibility.
