The effect of dynamic loading on bacterial microleakage of the dental implant fixture-abutment interface: An in vitro study

The Journal of Indian Prosthodontic Society, 2021
Aim: Bacterial micro leakage at implant-abutment interface under functional loading is an important factor, may lead to crestal bone loss and affect the long term success of dental implants.
