Abstract

This work compares the consequence of argon bombardment plasma treatment on sandblasted large-grit, acid-etched (SLA) and hydroxyapatite (HA) treated titanium surface. Titanium disc specimens were distributed into two groups depends on the surface treatment (SLA, HA). The SLA and HA-coated surfaces were further subdivided according to non-plasma and plasma treatments. An argon plasma treatment was done at ambient temperature under vacuum. The specimens (surface treated) were subjected to surface analysis using field-emission scanning electron microscopy, a three-dimensional optical profiler, and X-ray photoelectron spectroscopy (XPS). Furthermore, contact angle examination was performed via the sessile drop technique.

Highlights

The utilization of titanium-based implant materials in the field of biomedical, orthopedic, and dental implants has drastically increased owing to their excellent biocompatibility, yield strength, satisfactory hardness, and relatively low weight [1,2,3]
The surface morphology remained unchanged after plasma treatment for both groups
The surface roughness and surface topography revealed that there are no noteworthy changes in the samples with or without plasma treatment process; this was further confirmed from the FE-SEM image

Summary

Introduction

The utilization of titanium-based implant materials in the field of biomedical, orthopedic, and dental implants has drastically increased owing to their excellent biocompatibility, yield strength, satisfactory hardness, and relatively low weight [1,2,3]. The long-term health problems associated with the discharge of V and Al ions in to the interior body have posed major limitations to the use of the most common alloy, Grade 5 titanium (Ti-6Al-4V), for dental implants with excellent fatigue and yield strength [5,6]. Surface roughness can be achieved either by the addition (coating) or subtraction of an implant material. The combination of chemical treatment and grit blasting, i.e., sandblasted, large-grit, acid-etching treatment, is widely used to enhance osteointegration by creating a hydrophilic implant surface [9]
