The authors wish to make the following corrections to the citations in the published paper [1].

Page 1903:

• Line 4 “They are completely placed into the jaw bone and give support to a dental prosthesis [3].”
  Replacing “[3]” with “[1]”.
• Line 8 “Over the last decade, there has been a universal growing interest in dental implants, which are used to treat about one million people per year around the world [4].”
  Replacing “[4]” with “[3]”.
• Line 11 “the higher number of elderly people in the population and higher public awareness [4].”
  Replacing “[4]” with “[1]”.
• Line 15 “Thus, using endosseous titanium implants is more convenient with better functionality than conventional dentures [5].”
  Replacing “[5]” with “[4]”.
• Line 18 “such as a lack of biological interaction and interfacial stability with bone tissue [3,6].”
  Replacing “[3,6]” with “[5]”.
• Line 21 “Titanium and its alloys have been reported as the materials of choice for most orthopedic and dental implants due to their outstanding mechanical properties and biocompatibility [7].”
  Replacing “[7]” with “[6]”.
• Line 25 “this dense structure of implants can cause a mismatch between the Young’s modulus of the titanium implant (110 GPa) and natural cortical (17–20 GPa) and cancellous bone (around 4 GPa) [8,9].”
  Replacing “[8,9]” with “[7–9]”.

Page 1904:

• Line 21 “Sand blasting with stiff particles such as alumina, TiO2 and ceramic has also been suggested to roughen the dental implant surface [4].”
  Replacing “[4]” with “[3]”.

Page 1905:

• Line 25 “at room temperature it tends to be categorized as α phase and transfer to β phase as the temperature exceeds 883 °C [23].”
  Replacing “[23]” with “[8]”.
• Line 35 “Through the years, several types of titanium alloys have been developed as implant biomaterials such as Ti–6Al–4V, Ti–Nb–Ta–Zr [24], Ti–Ni–Ta [25], Ti–15Mo–5Zr–3A [8].”
  Replacing “[24]”, “[25]” and “[8]” with “[23]”, “[24]” and “[25]” respectively.

Page 1906:

• Line 15 “Attempts have also been made to produce porous Ti alloy compacts (Ti–15Mo–5Zr–3Al) using a hot-pressing technique, which could reduce the Young’s modulus to within the range of cortical bone [8].”
  Replacing “[8]” with “[25]”.

Page 1907:

• Line 28 “By increasing the porosity, a structure was created which closely mimics that of trabecular bone [3].”
  Replacing “[3]” with “[5]”.

Page 1908:

• Line 30 “With the casting method, in particular, machining and other finishing steps are required with a large amount of waste material [23].”
  Replacing “[23]” with “[8]”.
• Line 35 “It is less expensive and has reduced amounts of waste compared to the other production methods available [23].”
  Replacing “[23]” with “[8]”.

Page 1909:

• Line 37 “Additive processes are in general less time consuming overall [72] and allow the creation of porous structures with different unit cells [40] and high resolution (i.e., small cell sizes) [3].”
  Replacing “[3]” with “[75]”.
• Line 40 “such as dental, craniofacial, maxillofacial and orthopedic implants [75].”
  Replacing “[75]” with “[59]”.
• Line 42 “comprising a compact core and irregular porous shell by incorporating (SLS) for the porous surface and (SLM) for the solid core (Figure 2).”
  “(Figure 2)” should be removed.

Page 1911:

• Line 3 “a post-sintering heat treatment has been suggested by Clook and co-workers.”
  Replacing “Clook” with “Cook”.
• In Table 1 row 3 Reference [4].
  Replacing “ [4]” with “[3]”.

Page 1912:

• Line 42 “Thus, the trabecular structure has the potential to produce devices well-suited for dental and orthopedic implants [3].”
  Replacing “[3]” with “[5]”.
• “The anodization of the titanium can produce a nanoporous surface that can increase osteoblast cell (MC3T3-E1) proliferation and attachment on implant surfaces [10].”
  Replacing “[10]” with “[88]”.

Page 1913:

• Line 1 “Pore geometry is likely to have a strong effect on cell attachment and matrix formation [88].”
  Replacing “[88]” with “[89]”.
• Line 8 “but cell activity and migration were best in the pyramidal design with a 400–620 μm pore size and 75% porosity [89].”
  Replacing “[89]” with “[90]”.
• Line 26 “which enhanced the osseointegration process [90].”
  Replacing “[90] with [91]”.
