“…These studies confirm that roughening of the titanium dental implants increases their mechanical fixation to the bone, but not their biological fixation. [18][19][20] A. Karacs et al 21 investigated the morphology of machined, blasted and laser-treated surfaces of titanium. The Al 2 O 3 blasted surface has a unique surface morphological characteristic that enhances the osseointegration process.…”

Dental implants are mechanical components that are used to restore the mastication (chewing) function and/or aesthetic appeal because of tooth loss or degradation. They are affixed (screwed) into the upper or lower jaw and act as a base for single or bridge-type tooth replacements. They are mostly manufactured from titanium alloys. The surface integrity of the manufactured implant may have a significant effect on the functioning and success of the implant. A systematic review is described on the effect of engineered surface integrity on the performance of titanium dental implants as regards the implant fixation, mechanical performance, bone growth and cell response. The need for surface engineering of the implant is introduced first. This includes the mechanical, surface-integrity and biocompatibility-required properties. This is followed by introducing and discussing the dedicated surface-modification processes currently employed. These include: abrasive blasting, electrochemical processes, hybrid processes and laser modification. The mechanical and biocompatible properties of an implant are the most crucial factor for their application in biomedical use. Hence, the present review article focused on the latest improvements to dental implant design based on the mechanical and biocompatible properties. The physical contact of an implant with respect to its surface roughness is an important factor in dental implant design. The surface roughness of an implant on the macro, micro and nano scales have specific effects on the implant's contact with the surrounding tissue of the bone. In addition, the biocompitability of titanium material is very important to develop a sustainable dental implant. Looking into the importance of the above mechanical and biocompatible properties of bone implants, the authors review elaborately the development of titanium-based implants with reference to the above properties.

Najprej je predstavljena potreba po obdelavi povr{ine vsadka. To vklju~uje zahtevane mehanske lastnosti, celovitost povr{ine in biokompatibilnost. Temu sledi predstavitev in razlaga trenutno uporabljanih postopkov za namensko spremembo povr{ine.

“…[4][5][6][7][8][9] Further increasing surface roughness does not result in an increase in bone-implant contact, and may result in decreased implant retention. 10,11 We propose that osteoblasts encountering a very rough surface may actually interact with an area of smoother surface between the peaks and, therefore, perceive the surface as smooth.…”

Difficulty in removing implants used in trauma patients can be a complication, and increased bone-implant adhesion likely is a major contributing factor. In vitro studies have shown that surface morphology of implant materials has the ability to influence cellular responses, with polished surfaces decreasing the potential for mineralization. This study examined the effect of polishing commercially pure titanium (cpTi) and the titanium alloy TAN on the removal torque and percentage bone-implant contact in cortical and cancellous bone of sheep. Polishing had a significant effect on both removal torque and percentage bone-implant contact, with the polished implants demonstrating a lower removal torque in both cortical and cancellous bone. Polished cpTi and stainless steel were similar in terms of surface roughness and removal torque. However, polished TAN, which was not as smooth as polished cpTi, did not show the same low level for reducing removal torque. Improved polishing of TAN should reduce the removal torque further. The results of the study show that polishing is promising in improving the ease of implant removal after fracture fixation and repair. ß

“…Grit-blasted implants have been reported to exhibit improved reactivity on the titanium surface due to removal of contaminants on the surface layer and production of fine irregular unevenness on the surface by blasting with titanium oxide or alumina oxide 40) . Another study suggested that the bone/implant contact area is larger in grit-blasted implants than machined implants, and therefore, cells on the rough surface can exist and proliferate for a longer period 41) .…”

Abstract:A newly developed titanium alloy, Ti-15%Zr-4%Nb-4%Ta (Ti15Zr4Nb4Ta), has been shown to have excellent mechanical characteristics, corrosion fatigue strength, anticorrosion, cytocompatibility, and biocompatibility. The purpose of this study was to compare the bone mineral density (BMD) and area of newly formed bone around Ti15Zr4Nb4Ta implants to that around Ti-6%Al-4%V alloy (Ti6Al4V) implants. We inserted 2 types of implants (surface treat of the machine and the blast implant) in New Zealand white rabbit femurs under general anesthesia. The rabbit was done perfusion fixation of 4, 8, 16, 24, and 48 weeks later, and the femurs with the implants were collected and we observed the surrounding bone by an implant drawing test. We measured the BMD and the area of the newly formed bone surrounding the implant inserted part using image analysis software Image-Pro PLUS Ver. 4.0 ® which it developed newly in micro focus computed tomography (micro CT). The results showed the machine and the blast implant together, which the BMD and area around the Ti15Zr4Nb4Ta implants were comparable to or greater than those around the Ti6Al4V implants. These results suggested that the new alloy, Ti15Zr4Nb4Ta, might be useful for orthopedic or dental implants with the added advantage of superior biologic safety and mechanical properties than the current alloy, Ti6Al4V.
