Morphometric Changes Induced by Cold Argon Plasma Treatment on Osteoblasts Grown on Different Dental Implant Surfaces

摘要

Treatments for enhancing surface energy were studied in an effort to create a more favorable environment for cell adhesion. Cold argon plasma (CAP) is able to improve titanium-cell contact, producing hydrophilic surfaces with higher wettability. The aim of this in vitro study was to estimate the early cell morphology after CAP treatment of different commercially available titanium surfaces. Surface wettability was significantly augmented in all the treated samples. The authors investigated how CAP affected the behavior of osteoblasts by evaluating the cell morphology outcome. Cell surface areas differed in a statistically significant way when plasma-treated samples were compared to the untreated ones. The positive effect of CAP was shown on smooth, moderately rough, and rough implant surfaces.
