Research progress on antibacterial activity of medical titanium alloy implant materials.

Titanium and its alloys are the preferred materials for medical implants. However, easy infection is a fatal shortcoming of Ti implants. Fortunately, the ongoing development of antibacterial implant materials is a promising solution, and Ti alloys with antibacterial properties hold immense potential for medical applications. In this review, we briefly outline the mechanisms of bacterial colonization and biofilm formation on implants; discuss and classify the major antimicrobials currently in use and development, including inorganic and organic antimicrobials; and describe the important role of antimicrobials in the development of implant materials for clinical applications. Strategies and challenges related to improving the antimicrobial properties of implant materials as well as the prospects of antibacterial Ti alloys in the medical field are also discussed.

Research in Tissue Engineering Scaffold Materials for Alveolar Bone Repair.

An increasing number of scaffold materials are available for repairing alveolar bone defects. As each material has its own advantages and disadvantages, these characteristics should be carefully considered. This paper presents a review of the currently available materials for repairing alveolar bone defects, including artificial ceramics, polymers, and metals. The combination of seed cells or growth factors with these materials is the future trend for the treatment of alveolar bone defects. In this study, a comprehensive analysis of the advantages, disadvantages, and development status of various materials is carried out, providing a basis for future material selection.
