Book excerpt: Abstract: Background: The existence of a microgap in two-piece implant system has been well documented in the literature. This microgap is in microns size and several in-vitro studies tested the microleakage through the microgap and its effect on hard and soft tissues. It was proven that this gap acts as a reservoir for bacteria which induced peri-implant tissue inflammatory reactions. Microleakage through the interface differ between implant body-abutment connections systems and study methodology. There is an increased demand for all ceramic crowns and zirconia abutments in the anterior sextant due to esthetic reasons. To our knowledge there is not enough information regarding leakage around zirconia abutments. Thus it was the purpose of the study to compare titanium abutments and zirconia abutments for microleakage under two different torque values.
