Marginal Leakage Around Fixed Dental Prosthesis - A review

International Journal of Research in Pharmaceutical Sciences, 2020
Marginal leakage is the intrusion into the space between all the restorative materials and cavity walls of fluids, bacteria, and ions. It can cause irritation of the pulp, change of color in the tooth and secondary caries, and may also result in restoration failure. The freshly placed prosthetic margins invariably leak.

In Vitro Bacterial Leakage at the Implant-Abutment Connection of Two Dental Implant Systems with Internal Connection

Frontiers in Dentistry, 2021
Objectives: Bacterial leakage at the implant-abutment interface is one of the main causes of peri-implant inflammation. One of the factors that influences bacterial leakage is the structural design of the interface. Considering the limited studies that have examined slip-joint connections, a comparative study of bacterial leakage was performed on two ...
