Investigation of Titanium Oxide Characteristics on Healing Abutments: Retrieval Characterization and Soft Tissue Compatibility

摘要

Overall IHA analysis revealed that anodization treatments that thicken the oxide layer may increase protection against corrosion and wear versus non-anodized IHA. Spectroscopic analysis indicated IHA were stable in the oral environment and the increased corrosion rate of retrievals was likely due to abrasions from unintentional loading and oral hygiene techniques in the oral cavity. Retrieval IHA were still several orders of magnitude more corrosion resistant than non-anodized cpTi2. The assessment of soft tissue compatibility indicated that crystallinity and thickness do not affect the long term viability of soft tissue cells when compared to a cpTi surface. The indifferent response of HGF-1 cells to sample surfaces indicate these may not be the properties that influence cell behavior. Viability trends suggest that surface topography and roughness more likely influencing cell responses. Therefore, treatments like anodization that alter the crystallinity and thickness of TiO_2 on implant components may not directly affect the attachment of soft-tissue cells in vivo. In conclusion, modifications of the T1O_2 surface, whether it is a change in thickness or crystalline structure, may benefit implant components in the post-implantation environment by attributing to corrosion resistance, while not effecting soft tissue cell behavior.
