Hideaki Sato, Yutaka Kameyama, Ryota Yoshikawa, Kaito Tabuchi, Chizuko Ogata, Satoshi Komasa
TL;DR
This study shows that coating pure titanium with a diamond-like carbon thin film helps prevent surface roughness during dental implant cleaning, reducing the risk of bacterial buildup.
Contribution
The study demonstrates that DLC thin films maintain titanium surface integrity during mechanical cleaning, offering a novel solution for preventing peri-implantitis.
Findings
DLC-coated titanium surfaces showed minimal roughness after repeated scratching.
Uncoated titanium surfaces experienced significant roughness increase during cleaning.
DLC thin films are effective in preventing plaque adhesion due to their non-stick properties.
Abstract
The purpose of this study was to clarify the physical durability of a diamond-like carbon (DLC) thin film coated on pure titanium. The titanium surface of the abutment does not have sufficient toughness to prevent an increase in surface roughness or damage when the implant is scaled using a professional mechanical implement. The scaling process used for the removal of the dental plaque adhered to the abutment surface could increase the potential for the deposition of oral microorganisms and the accumulation of plaque, which increase the risk of peri-implantitis. A DLC thin film is biocompatible material that is known for its toughness, including extreme hardness, high abrasion resistance, chemical inertness, and high corrosion resistance. Protecting the abutment surface with the application of a DLC might prevent plaque adhesion due to its non-stick property. There was little change in…
