Surface Modification of Titanium Plate with Anodic Oxidation and Its Application in Bone Growth

Abstract

Using implants for dental applications are well-accepted procedures as one of the solutions for periodontal defect repair. Suitable design and materials, their reaction with the surrounding hard tissues and interfacial biomechanical properties are still considered to be the primary criteria which need to be addressed. The purpose of present study was to evaluate the bone repair around pure titanium implants and porous surface using anodic oxidation technique, after their insertion in tibiae of rats (n = 15). Five animals received pure titanium-surface implants in tibia, 5 rough-surface implants (TiO 2 /Ti) in tibia and last five acted as control group. The interfacial integrity and compositional variation along the interface were studied using scanning electron microscope (SEM) with energy dispersive analysis of X-ray (EDX) and histopathology after 2 months. The rats were sacrificed 8 weeks after surgery and fragments of the tibiae containing the implants were submitted to histological analyses to evaluate new bone formation at the implant-bone interface as well as the tibiae were radio graphed. The SEM-EDX results confirmed the initial stability for the Ti implant, but the regeneration of new bone formation was faster in the case of TiO 2 /Ti implant, and hence could be used for faster healing. The results of the histological analysis showed that osseointegration occurred for both types of implants with similar quality of bone tissue. In conclusion, the porous-surface implants contributed to the osseointegration because they provide a larger contact area with surface roughness at implant-bone interface can help into the formation of physico-chemical bondage with the surrounding hard tissues.

Improved Osseointegration of a TiNbSn Alloy with a Low Young’s Modulus Treated with Anodic Oxidation

“…5), and could be attributable to anodic oxide on the surface of TiNbSn alloy rod. Osseointegration of titanium oxide has been reported extensively 34,35 , whereas the role of oxide has not yet been delineated. We propose that the superior osseointegration of TiO 2 prepared by anodization may be attributed to highly crystallized TiO 2 with pore sizes that facilitate the incorporation of elements crucial to bone formation (Ca, P) beyond the limit of solubility.…”

Titanium Dioxide Nanotube Arrays for Biomedical Implant Materials and Nanomedicine Applications

“…Titanium dioxide (TiO 2 ) nanotube arrays are also referred to as titania nanotube arrays (TNA). Nanotubes layered by anodization in particular, have garnered considerable interest in the enhancement of orthopedic procedures due to their inherent high quality and cost-effectiveness [1,2]. The anodization process produces continuous and vertically aligned TiO 2 nanotubes structure in an array form on the titanium (Ti) alloy surface as shown in Figure 1.…”

Surface Coating Effect on Corrosion Resistance of Titanium Alloy Bone Implants by Anodizing Method

“…A thin oxide layer grows on the implant's surface during this process. Properties of the layer depend on the electrolyte, production method, oxidation time, and electric parameters of the process (Kiel-Jamrozik et al, 2015;Szewczenko et al, 2015;Ziębowicz, Ziębowicz and Bączkowski, 2015;Al-Mobarak and Al-Swayih, 2014;Indira, Mudali and Rajendran, 2013;Fadl-allah, Quahtany and El-Shenawy, 2013;Bhola et al, 2011;Szewczenko et al, 2010;Narayanan and Seshadri, 2007;Nagy et al, 2005;Van-Gils et al, 2004;Roessler et al, 2002).…”
