Special Issue Information

Dear Colleagues,

Titanium and Ti-6Al-4V alloy are widely used for manufacture dental implants due to their good biocompatibility. Novel titanium alloys, especially β-type titanium alloys, are considered the future materials for dental implants. Thus, various manufacturing techniques are used to obtain biocompatible implants with the desirable mechanical properties. To increase bioactivity of titanium alloys, their surfaces are very often modified. Various methods are available for the bioactivation of metal surface: plasma electrolytic oxidation, sol–gel methods, plasma spraying, ion implantation, electrophoretic deposition, and chemical or physical vapor deposition. Functional coatings can be designed for dental implant applications. Bioactive coatings should be composed only by biocompatible compounds and do not form toxic corrosion or degradation products.

The following topics are within the scope of the Special Issue:

  • Manufacturing of titanium-based dental implants;
  • Surface treatment of dental implants;
  • Formation of bioactive coatings on a titanium alloy surface;
  • Enhancing antibacterial properties of titanium alloy;
  • Characterization of Ti-based implants for dental applications.

It is my pleasure to invite you to submit a manuscript for the Special Issue “Ti Alloys for Dental Implant Applications”. The broad scope of this Special Issue provides an excellent opportunity to submit full papers, short communications or review papers.

Sixty-four fractured commercially pure titanium (cp-Ti) narrow dental implants (NDIs) with similar macrogeometry and connection designs were studied after different implantation times in humans in order to determine their reliability and to evaluate the causes of the fracture. These NDIs were compared with other similar implants, made with alloyed titanium with 15% Zr and with 12% strained titanium. Original implants were tested under static and fatigue conditions, simulating the tri-axial loads in the mouth by means of a Bionix hydraulic test machine. Fractography was studied using field-emission scanning electron microscopy (FSEM). The results showed that cp-Ti NDI exhibits low strength for mechanical cycling, and the alloyed Ti and strained titanium increase the mechanical strength, guaranteeing long term mechanical behavior. NDIs fractured due to fatigue, and, in some cases, the presence of cracks in the original NDIs quickly led to fracture. These cracks were attributed to plastic deformation during machining were found to be exacerbated due to acid etching in the passivation process. All cases of fracture were cp-Ti dental implants due to the low fatigue limit. The results show that, when titanium is alloyed or cold-worked, the fatigue limit is higher than cp-Ti. This in vitro research will help clinicians to select a better NDI system for safer treatment. Full article
