EFFECT OF LAB PROCEDURES AND ULTRASONIC-BATH CLEANING ON CUSTOMIZED IMPLANT ABUTMENT POLLUTION: AN IN VITRO STUDY.

This document is a scientific study that examines the contamination levels on dental abutments and the effectiveness of a cleaning protocol. The study finds that custom-made abutments have surface pollutants, and laboratory procedures increase the amount of pollutants. However, the cleaning protocol tested is highly effective in cleaning both titanium and zirconia abutments. The study suggests that decontaminating abutments before placement may improve tissue integration. [Extracted from the article]
