To evaluate bond strength of orthodontic brackets to temporary crowns.
A bis-acrylic composite was used to create a total of 25 discs, which were then divided into five groups based on how their surfaces were treated with black, blue, green, and sandblasted diamond burs, in addition to a control group. Software called SPSS was used to analyze the outcome.
The average pressures measured for the green bur, black bur, and sandblasting, respectively, were 12.05 MPa, 12.87 MPa, and 19.25 MPa. Comparing the control and blue groups, a substantial variation in shear bond strength was only noticed with reference to sandblasting.
The binding strength of orthodontic brackets is increased by sandblasting temporary crowns.
评估正畸托槽与临时冠的粘结强度。
使用双丙烯酸复合材料制作25个圆盘，除对照组外，根据其表面用黑色、蓝色、绿色和喷砂金刚石车针处理的方式分为五组。使用名为SPSS的软件分析结果。
绿色车针、黑色车针和喷砂处理的平均压力分别为12.05兆帕、12.87兆帕和19.25兆帕。比较对照组和蓝色组，仅在喷砂处理方面观察到剪切粘结强度有显著差异。
对临时冠进行喷砂处理可提高正畸托槽的粘结强度。
