“…However, this TiO2 layer can react with a NaOH solution and form an alkali titanate hydrogel on the surface.(T. Kokubo, 1996;Oh et al, 2014;Shahriyari et al, 2018) This layer is dehydrated and stabilized as a partially crystallized sodium titanate after treatment at 60°C for 3 hours. According to studies after chemical attack, titanate has a gel structure (Gil et al, 2002;Kizuki et al, 2014;Tadashi Kokubo & Yamaguchi, 2015;Oh et al, 2014;Shahriyari et al, 2018), which is partially crystallized (Kim et al, 1997;Tadashi Kokubo & Yamaguchi, 2015) for sodium titanate (Na2Ti5O11) and rutile (TiO2).(M.…”

Titanium is a complex element and presents more than one crystallographic form, at room temperature it has a hexagonal crystal structure that transforms into a body-centered structure at 800ºC, and a melting point of 1670ºC ± 5ºC. Titanium alloys have superior mechanical properties to Ti c.p. in addition to excellent biocompatibility, a characteristic makes them the material of choice in orthopedic and dental applications. The alloy used in this study was the Ti-6Al-4V ELI alloy, obtained in cylindrical shape, sanded, and subsequently subjected to thermochemical treatment with NaOH. The physicochemical characterization was performed by the techniques of X-ray fluorescenic spectrometry (XRF), scanning electron microscopy (SEM), X-ray diffractometry (XRD) and X-ray excited photoelectron spectroscopy (XPS). A biphasic structure (α and β) and the formation of an alkali titanate hydrogel (sodium titanate (Na2Ti5O11)) on the surface were observed, due to the reaction of the TiO2 film with the NaOH solution. It is concluded the immersion of the samples in NaOH, resulting in the crystallization of the titanate hydrogel layer, may favor the formation of calcium phosphates, as well as the bone/implant interaction.

“…For this purpose, 10 4 cells were placed DMEM in each well containing the sample, and three wells were considered as controls. 31 The plates were placed in the incubator. After 1, 4, and 7 days, the plates were removed from the incubator, and 500 μL of the solution containing 0.5 mg/mL MTT in SBF solution was poured into each well and placed in the incubator for 2 h. DMSO was used to dissolve the formed formazans.…”

In this research, the Sr‐HA/poly(ɛ‐caprolactone) (PCL) composite scaffold was fabricated using a solvent‐based extrusion method. First, the coprecipitation method was used to synthesize the Sr‐HA powders. For this purpose, strontium was doped into hydroxyapatite (HA) with molar ratios of 0%, 2%, 4%, and 6%. Then, the solvent‐based extrusion method was used to manufacture the 3D printed Sr‐HA/PCL scaffolds. X‐ray diffraction analysis, Fourier transform infrared spectrum, and field emission scanning electron microscope of all samples calcined at 900°C for 1 h indicated the formation of a single‐phase HA structure. The composition of the synthesized powders was confirmed using an inductively coupled plasma test and energy‐dispersive X‐ray spectroscopy. The compressive strength of Sr‐HA/PCL scaffolds compared with pure HA increased from 3.8 to 5.9 MPa. Results of the MTT test showed that Sr‐HA/PCL scaffolds were biocompatible and the growth and proliferation of MG63 cells on the surface of scaffolds increased with the presence of strontium.

“…Atualmente, a maior produção em implantes dentais são á base de titânio comercialmente puro (Ticp) e a liga de titânio (Ti-6Al-4V) (1,2) , por apresentarem biocompatibilidade ao ambiente biológico, boa resistência em relação a degradação química, propriedades mecânicas favoráveis à implantodontia, como o baixo módulo de elasticidade, alta taxa de resistência a força, favorecendo uma excelente resposta clínica (1,2) .…”

“…Contudo, mesmo esses materiais apresentando qualidades em suas propriedades, pode ocorrer a degradação química e/ou mecânica de modo a promover a liberação de íons, que quando em grandes quantidades geram respostas imune e inflamatória, sendo um dos fatores responsáveis pelas falhas dos implantes. Além disso, os referidos materiais possuem características biocompatíveis mas não são bioativos, não apresentando propriedades antibacterianas associadas (1,2) .…”
