Clinical evaluation of casting metal full crown made by Bonn method to restore abutment of removable partial denture

目的:评价波恩式方法制作的金属全冠修复可摘局部义齿基牙的效果。方法:选择48颗基牙残冠,首先恢复牙体解剖形态,然后利用波恩制作方法完成铸造金属全冠,基牙修复完成后,戴入原可摘义齿,定期临床检查,评价修复效果。结果:经过3～6个月的随访观察,48颗患牙经波恩冠修复后获得满意效果,1例患者出现牙龈炎。结论:可摘局部义齿基牙牙体缺损进行全冠修复时,波恩制作方法简单易行,效果好。

PURPOSE： To evaluate the effect of casting metal full crown made by Bonn method to restore abutment of removable partial denture. METHODS： The first step was to restore the anatomical shape of 48 abutment residual crowns, then casting metal full crown was made by Bonn method. After the abutment was restored, removable dentures were mounted, and regular clinical examination was performed to evaluate the short-term result. RESULTS： After three to six months, 48 residual teeth were restored successfully by Bonn method, the results were satisfactory, one was found to have gingivitis.
