description One of the most common problems with modular implants is that they begin to loosen over time. Implant loosening issue is of concern to physicians since implant revision surgery is an extremely difficult operation. A st able fixation between modular taper junctions is necessary to prevent motion and corrosion. There are many factors that can affect the loosening problem. This study aimed to determine the influence of surface roughness and taper angle on junction strength of modular biomedical implant in two different compression forces including 1500N and 2500N.
