“…In another study using the dorsal skinfold chamber model in hamsters a slight increase in leukocyte recruitment and a more sluggish recuperation of infl ammatory parameters was detected for Ti6Al4V when compared with cpTi (Pennekamp et al, 2006). Compared with stainless steel, the overall infl ammatory response to Ti6Al4V was very similar (Ryhänen et al, 1998;Kapanen et al, 2001). Moreover, Ti6Al4V is considered as the material of choice for cementless implant materials in orthopaedics (Head et al, 1995) and successful clinical results were reported for Ti6Al4V dental implants that were machined and acid etched (De Leonardis et al, 1999) and sand-blasted and acid-etched (Bratu et al, 2009).…”

Implants made of commercially pure titanium (cpTi) are widely and successfully used in dentistry. For certain indications, diameter-reduced Ti alloy implants with improved mechanical strength are highly desirable. The aim was to compare the osseointegration of titanium-zirconium (TiZr) and cpTi implants with a modifi ed sandblasted and acid-etched (SLActive) surface and with a Ti6Al4V alloy that was sand-blasted and acid-washed. Cylindrical implants with two, 0.75 mm deep, circumferential grooves were placed in the maxilla of miniature pigs and allowed to heal for 1, 2, 4 and 8 weeks. Undecalcifi ed toluidine blue-stained ground sections were produced. Surface topography, area fraction of tissue components, and bone-to-implant contact (BIC) were determined. All materials showed signifi cantly different surface roughness parameters. The amount of new bone within the implant grooves increased over time, without signifi cant differences between materials. However, BIC values were signifi cantly related to the implant material and the healing period. For TiZr and cpTi implants, the BIC increased over time, reaching values of 59.38 % and 76.15 % after 2 weeks, and 74.50 % and 84.67 % after 8 weeks, respectively. In contrast, the BIC for Ti6Al4V implants peaked with 42.29 % after 2 weeks followed by a decline to 28.60 % at 8 weeks. Signifi cantly more surface was covered by multinucleated giant cells on Ti6Al4V implants after 4 and 8 weeks. In conclusion, TiZr and cpTi implants showed faster osseointegration than Ti6Al4V implants. Both chemistry and surface topography might have infl uenced the results. The use of diameter-reduced TiZr implants in more challenging clinical situations warrants further documentation in long-term clinical studies.

“…However, in vivo and in vitro studies of NiTi implants show excellent biocompatibility [ 124 -126 ]. There are few reports on release of Ni, but the amount of released nickel is not suffi cient to induce such reactions [ 127 ]. Titanium alloys tend to repassivate faster than the stainless steel and other biomedical alloys; however, repassivation of titanium in vivo is slower than in vitro.…”

Metallic materials have been used as biomedical implants for various parts of the human body for many decades. The physiological environment (body fl uid) is considered to be extremely corrosive to metallic surfaces; and corrosion is one of the major problems to the widespread use of the metals in the human body since the corrosion products can cause infections, local pain, swelling, and loosening of the implants. Recently, the most common corrosion-resistant metallic biomaterials are made of stainless steels and titanium and its alloys along with cobaltchromium-molybdenum alloys. It is well known that protective surface fi lms of the alloys play a key role in corrosion of the metallic implants. Key documents on the corrosion behavior of the metallic biomaterials in human body have been compiled under this chapter as a review. Keywords Metallic biomaterials • Corrosion • Physical body fl uid • Bioactive materials • Implant IntroductionThe main question is, "what is the most important property for a metallic biomaterial?" Clearly, the answer is biocompatibility . In addition, it is well known that corrosion is one of the major problems affecting the biocompatibility of orthopedic devices made of metals and alloys used as implants in the human body. Compared to other implants, metallic implants have excellent mechanical properties such as high elasticity, tensile strength, wear resistance, and machining.
