“…The anodic oxidation improves the corrosion resistance of the CP titanium alloy. 11 Titanium has excellent corrosion resistance, good fatigue strength and acceptable fracture toughness, but it has poor sliding characteristics. These alloys fail by galling and often exhibit high and unstable friction coefficients.…”

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. Keywords: implants, titanium, surface roughness, systematic review, surface engineering process, hybrid process, mechanical machining, chemical treatment Zobni vsadki so mehanske komponente, ki se jih uporablja za obnovo funkcije`ve~enja in/ali iz estetskih razlogov zaradi izgube ali poslab{anja zoba. Pritrjeni (privija~eni) so v zgornjo ali v spodnjo~eljust in slu`ijo kot osnova za nadomestni zob ali za mosti~ek. Ve~inoma so izdelani iz titanovih zlitin. Integriteta povr{ine izdelanih vsadkov lahko pomembno vpliva na delovanje in uspe{nost vsadka. Opisan je sistemati~en pregled o vplivu in`enirske celovitosti povr{ine na zmogljivost titanovega dentalnega vsadka glede na pritrditev vsadka, mehanske zmogljivosti, vra{~anja kosti in odziva celic. 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. To vklju~uje: abrazivno peskanje, elektrokemijske procese, hibridne procese in modifikacijo z laserjem. Mehanske in biokompatibilne la...

“…Commercially pure titanium (cp-Ti) and its alloys are commonly used for dental implant applications owing to their good mechanical properties, excellent corrosion resistance in biological fluids as well their very low toxicity [1,2]. The high corrosion resistance of cp-Ti and its superior biocompatibility is related to the formation of a stable and tightly adherent protective titanium oxide film (1.5-10 nm thick) on its surface, like TiO 2 , under contact with the surrounding environment [1,[3][4][5][6][7][8].…”

Tribocorrosion Behavior of Calcium- and Phosphorous-Enriched Titanium Oxide Films and Study of Osteoblast Interactions for Dental Implants

Titanium (Ti) dental implants are frequently exposed simultaneously to a corrosive environment and cyclic micromovements at implant/abutment and implant/ bone interfaces, becoming part of a tribocorrosion system. Thus, wear debris and corrosion products/ions can be released to peri-implant tissues and induce inflammatory reactions leading to implant failure. Moreover, the poor osseointegration is also one of the main problems affecting dental implants lifetime. Surface modification strategies have been proposed to design novel Ti oxide-based multifunctional surfaces that are able to simultaneously improve cellular functions and provide enhanced tribocorrosion resistance. Hence, the main objective of this work was the synthesis of Calcium (Ca)-and Phosphorous (P)-enriched Ti oxide films aimed to display superior wear/corrosion performance and simultaneously, to enhance osteoblast-material interactions. Ca-and P-enriched films were synthesized by plasma electrolytic oxidation (PEO) and their characteristics were assessed by Field emission scanning electron microscopy, profilometry, energy-dispersive X-ray spectroscopy, X-ray diffraction, and water contact angle measurements. PEO-treated samples were subjected to pin-on-disk reciprocating sliding tests in artificial saliva at 37°C. The viability of MG63 cells cultured on PEO-treated samples was investigated by MTT assay, and their adhesion ability by SEM and confocal laser scanning microscopy. The wear/corrosion behavior of Ti was improved after PEO treatments and the electrolyte composition appeared to play a crucial role both on its corrosion tendency and mechanical wear resistance. It is believed that this improvement is related to the higher rutile/anatase ratio exhibited by Ca-and P-enriched surfaces. Osteoblasts were well spread on these surfaces displaying improved viability/proliferation compared to Ti.

“…The chemical composition of the oxide layer depends on the chemical composition of the surface of the sample as well as on the electrolyte used. In the case of the Ti-6Al-4V alloy, besides TiO 2 , Al 2 O 3 and V 2 O 5 are also observed [23], whereas in the case of Ti-6Al-7Nb, the surface layer is composed of TiO 2 , Al 2 O 3 , and Nb 2 O 5 [24,25]. Despite many years of investigations on the corrosion resistance of the Ti-13Nb-13Zr alloy in different environments, new publications concerning this problem are appearing regularly [26][27][28][29].…”

This work presents the results of the investigations on the electropolishing and anodic oxidation of the Ti-13Nb-13Zr titanium alloy. Electropolishing was conducted in the solution containing ammonium fluoride and sulfuric acid, whereas the solution of phosphoric acid was used for anodic oxidation of the alloy. The influence of electropolishing and anodization process parameters on the texture (scanning electron microscopy (SEM)) and chemical composition (X-ray photoelectron spectroscopy (XPS)) of the surface layer was established. Electrochemical impedance spectroscopy in 5 % NaCl solution was used for the determination of the corrosion resistance of the alloy.
