Single implants and their restoration
When any restoration, provisional or definitive, is cemented over an abutment, the force of the expressed cement can displace the peri-implant mucosa and cement can be forced apical to the crown margin. Therefore, complete removal of all the excess cement is essential to prevent adverse peri-implant responses from the soft tissue or bone. Problems associated with residual cement left behind from incomplete cement removal were first reported in 1999. The potential post-cementation problems that can arise include bleeding, soreness, acute swelling, the presence of purulent exudate, and over time even radiographic evidence of actual bone loss.
