“…In contrast to the study of Gottlow et al (2010), we examined the dynamics of bone healing by using four different healing periods. When compared with another animal study (Thoma et al, 2011), a much more demanding and better discriminating model has been used in the present study, since the implant grooves created a standardised defect gap of 750 μm.…”

“…The physicochemical surface characteristics of Ti (SLActive) and TiZr (SLActive) implants might thus elicit different tissue responses. No signifi cant differences in BIC were found on Ti (SLActive) and TiZr (SLActive) within the grooves of cylindrical implants after 4 weeks of healing in miniature pigs (Gottlow et al, 2010) nor on standard screw-type Ti (SLActive) and TiZr (SLActive) dental implants after 2, 4 and 8 weeks of healing in dogs (Thoma et al, 2011).…”

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.

“…Therefore, in cases where a patient exhibits bruxism, or any other habit causing high occlusal masticatory forces, a grade 4 Cp-Ti implant, based on its standard value of static strength (yield and tensile strength), may have insufficient fatigue strength. In such cases, higher strength materials, such as titanium alloys, are necessary for dental implants [37][38][39] .…”

The objective was to investigate the influence of grade and surface topography of commercially pure titanium (Cp-Ti) on fatigue properties evaluated via staircase method. Cp-Ti grades 2 and 4 were roughened by shot blasting and acid etching, and compared with machined specimens. Yield force under static loading for Cp-Ti grades 2 and 4 were 672±51 and 1,088±93 N for machined and 724±99 and 1,118±96 N for roughened group. Yield force under cyclic loading for Cp-Ti grades 2 and 4 decreased 27 and 40% compared to static loading. Cp-Ti grade 4 demonstrated significantly greater decrease in yield force after cyclic loading; however surface topography had no effect.

“…Therefore; several materials and alloys have been tried for decades to find out the ideal biocompatibility with excellent physical features. Titanium and zirconium elements have been well documented and presented to have better tissue biocompatibilities and acceptable physical properties, when compared to others [93,94]. It is been shown that alloys of these materials can present augmented biologic and physical features while corrosion aspect of those alloys is still questionable.…”

Evaluation of a New Titanium‐Zirconium Dental Implant: A Biomechanical and Histological Comparative Study in the Mini Pig

Abstract: It is concluded that the TiZr1317 implant with a hydrophilic sandblasted and acid-etched surface showed similar or even stronger bone tissue responses than the Ti control implant.
