Novel Nano-TiO2/ZrO2 Coating on Implant Abutment Surface with Atomic Layer Deposition

Titanium abutment as part of superstructure on dental implants has been used for years due to its excellent mechanical property and bio-inert property. However, colonization by oral microbial biofilm on the Titanium (Ti) alloy surface may lead to peri-implantitis as the frequent biological complication. Coating of Ti surfaces has been one of the approach to reduce microbial biofilm formation and colonization. Objectives: To investigate the surface-altering properties of Ti implant abutment material with nano-TiO2/ZrO2 coating using Atomic Layer Deposition (ALD) technique.
