“…These results are confirmed by the findings of Majumdar et al [33]. Numerous previous studies have claimed that the highest surface roughness displays the lowest water titanium contact angle, and subsequently, more osteoblasts adhere to and proliferate on the titanium surface [34]. In addition, it may be attributed to the titanium dioxides displayed on the surfaces of the titanium alloy being more hydrophobic than the strontium oxides.…”

Dental implants can be made of various materials, and amongst them, titanium and titanium alloy were the materials of choice for dental implants for many years because of their biocompatibility. The two alloys have a high level of biocompatibility, a lower modulus of elasticity, and better corrosion resistance than other alloys. Thus, they are frequently utilized in biomedical applications and mostly replace stiff fabrics. The latest advances in a new strontium oxide–cp titanium composite alloy are the main topic of this research. With regard to biomedical applications, additions of strontium oxide were synthesized at three distinct weight percentages (2%, 4%, and 6% by wt%). Powder metallurgy was used to create the alloys, which were then sintered by heating the samples. The effects of adding strontium oxide were analyzed by utilizing measurements of the Brinell hardness, X-ray diffraction, porosity, diametral tensile strength, roughness, and wettability of the finished surfaces. The results show that adding more strontium oxide (gradually increasing the ratio from 2% SrO to a 6% addition) raised the roughness and porosity. However, the microhardness and diametral tensile strength were enhanced with an increase in the volume fraction of strontium oxide particles. In conclusion, the alloy that contained 6 wt% strontium oxide microparticles had reasonably high mechanical properties and might be regarded as suitable for use in dental and medical applications due to its high wettability or, in other words, its low contact angle. The Brinell testing results for the diametral tensile strength, microhardness, and porosity of the generated strontium oxide–cp titanium composite alloy demonstrate its high potential for usage as a biomaterial, particularly in dental applications.

“…The properties of the bioactive glass alter as it changes to hydroxyapatite (HA). Also extremely essential to the design for bioglass scaffolds in loaded bone regeneration are in vitro or in vivo environments for time-dependent mechanical responses [25,26]. This research's objective was to manufacture porous scaffolds made from the bioglass 13-93 that had interconnected pores using the salt leaching technique.…”

 The maximum compressive strength of the bioglass scaffold was found to be about 5.6MPa.  The prepared scaffold of bioglass has open porosity and interconnection ranging from about 75 to 78 %.  The glass scaffolds can be considered promising for bone defects and replacement applications.Bioglass offers a variety of uses for tissue engineering due to its good biocompatibility and chemical composition, similar to a mineral portion of the body. The synthesis of bioglass 13-93 scaffold was achieved by salt leaching technique, and potassium chloride (KCl) was used as porogen with particle sizes of (200-250) μm. Then, sintering to 750 •C for around 1 hour was performed. The resultant materials were examined by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). They were immersed in a solution of simulated body fluids (SBF) for 7 and 14 days, respectively. Initially, calcium phosphate was created. After 7 and 14 days, the surface comprised of developed crystalline apatite. The bioactivity of scaffolds that were created and examined. The FTIR, SEM, and XRD experiments were done before and after immersion of the sample in SBF. The results showed that the scaffolds contained open and interconnected pores with porosities ranging between (75-78%). The maximum value of compressive strength of the prepared scaffold was about 5.6MPa. Based on the obtained results, the glass scaffolds can be considered promising for bone defects and replacement applications.
