What can excessive loading of an implant cause?

Excessive loading of an implant primarily leads to mechanical failure, which can manifest as loosening or fracture of the implant. When an implant is subjected to forces greater than what it was designed to withstand, it can compromise the stability of the connection between the implant and surrounding bone. This is because implants rely on a balance between the forces applied to them and the support of the surrounding bone structure; exceeding that capacity can weaken the bond, resulting in failure.

The consequences of excessive loading can range from minor complications, like loosening of the abutment screw or crown, to more severe outcomes, including fracture of the implant itself or surrounding bone. Therefore, understanding the limits of load that an implant can bear is crucial for successful implant placement and longevity. Proper load distribution and adherence to recommended guidelines during the restoration phase is vital to prevent these mechanical issues.
