“…Simon et al reported that, in iron–sodium phosphate-based glass, the decrease in binding energy denotes the increase of electronic state density around phosphorus atoms. Similarly, the lower binding energy (∼132.54 eV) in the E-Si biomaterial shown by P 2p 3/2 spectra recognizes that P bonded to the oxygens in (PO 4 ) 3– groups and shows that the number of P–O – state may be higher . Meanwhile, the binding energy of P 2p spectra increases when electron density decreases around the P atom and results in PO bonds and Si–O–P/P–O–P linkages.…”

Among the wet chemical nanoparticle fabrication techniques, the sol−gel process happens through hydrolysis and subsequent polycondensation reactions. The bioactive glass known as the 45S5 SiO 2 -Na 2 O-CaO-P 2 O 5 quaternary system has intricate chemistry, yet its advantages benefit the biomedical field on an enormous scale. The order in which the ethanol and TEOS inclusions are exchanged was investigated in this work because it has a direct impact on the early hydrolysis process. Another strategy involves adding phosphate species to the sol before gelation, modifying the network chemistry, and interpreting the findings. Adding phosphate species before gelation in the biomaterial (E-Si-P) resulted in the formation of hydroxyapatite and other calcium silicate phases at 800 °C. Swapping ethanol and TEOS biomaterials (E-Si and Si-E) resulted in the sodium−calcium silicate phase only. Si-E with strong Si-O-Si siloxane rings demonstrated superior mechanical stability, hemocompatibility, and bioactivity. This compact Si-O-Si decreased the surface area of Si-E. XPS spectra revealed that E-Si-P has the lowest Na 1s binding energy (BE) and the highest BE for Si 2p. More Si-O − /Si-OH groups formed by E-Si make the network weak and decrease the surface area and protein adsorption. These differences significantly influenced the morphology, surface properties, mechanical studies, and compatibility test. This study has further unraveled the protocol to design a biomaterial with mechanical stability and load-bearing ability. In addition, the appropriate protocol to yield the desired property-rich biomaterial with preserved bioactivity, mechanical stability, cytocompatibility, as well and surface porosity has been elaborated in detail.

“…The success rate of Ti dental implant surgery can reach over 90%, but there are still about 10% failures . The key that determines the success of Ti implants is the effective osseointegration. − In addition, improving the antibacterial properties of the implant and suppressing peri-implant inflammation are also important factors for the success of the surgery. − Osteogenesis requires osteoblasts to adhere and grow on the surface of the implant. − And the occurrence of inflammation is mostly related to bacterial adsorption and biofilm formation on the surface of implants. − All of the above processes are closely related to the surface conditions of Ti implants. However, during the Ti implant manufacturing process, if the overall material is changed to achieve good surface conditions, the overall performance of the implant may be seriously affected.…”

Dental implants have become the mainstream strategy for oral restoration, and implant materials are the most important research hot spot in this field. So far, Ti implants dominate all kinds of implants. The surface properties of the Ti implant play decisive roles in osseointegration and antibacterial performance. Surface modifications can significantly change the surface micro/nanotopography and composition of Ti implants, which will effectively improve their hydrophilicity, mechanical properties, osseointegration performance, antibacterial performance, etc. These optimizations will thus improve implant success and service life. In this paper, the latest surface modification techniques of Ti dental implants are systematically and comprehensively reviewed. The various biomedical functionalities of surface modifications are discussed in-depth. Finally, a profound comment on the challenges and opportunities of this frontier is proposed, and the most promising directions for the future were explored.
