Summary: This study aims to design a personalized two-stage root analog implant (RAI) with a compact structure and uniform roughness to achieve better fracture resistance, initial osseointegration efficiency, and dispersed stress in immediate implantation. RAIs were manufactured using selective laser melting technology, and in vivo experiments showed that they had higher bone-implant contact and bone volume/total volume compared to conventional implants. Customized abutments were also designed for the RAIs, improving the masticatory ability of the beagle dogs.

Summary: In recent years, implantology has made significant progress, with the development of new alloys, surfaces, and geometries. This review analyzed the clinical differences between zirconia and titanium implants and found no statistically significant differences in fixed or overdenture restorations. However, there were concerns about the rigidity and potential fracture of zirconia.

Summary: This study proposes a two-step technique using plasma electrolytic oxidation (PEO) to improve the adhesiveness and mechanical properties of polypyrrole (PPy) films on implants. The results showed that PEO-treated titanium surfaces successfully achieved highly adherent PPy films with improved biocompatibility and corrosion resistance.

Summary: Current research on dental implants has focused on the influence of surface roughness on osseointegration rate, while studies on developing surfaces to improve interaction with peri-implant soft tissues are lacking. This study showed that implant discs with Ti-S surfaces promoted adhesion and proliferation of gingival fibroblasts in vitro, suggesting their potential for in vivo applications. Further research is needed to confirm these findings.

Summary: There is currently no consensus on the best Ti surface to reduce bacterial colonization on dental implants. Emerging smart release or on-demand activation surface coatings may be the most effective alternative for reducing microbial colonization on Ti surfaces, and future studies should focus on these technologies.

Summary: The study found that pretreating the titanium (Ti) surface with plasma electrolytic oxidation (PEO) can introduce hydroxyl (-OH) groups and create a porous surface structure with increased roughness and better mechanical/tribological properties. Additionally, surface silanization can introduce a cationic coating with bactericidal and corrosion-resistant abilities. These findings provide new insights into developing next-generation cationic coatings.

Summary: This study aims to systematically review the impact of titanium particles on oral-related cells by examining changes in molecular signatures. Through a systematic search, 12 eligible publications were identified, and a significant overlap of gene expression in oral-related cells exposed to titanium particles was found in four studies. Changes in immune/inflammatory and stress response processes, as well as toll-like receptor and mitogen-activated protein kinase signaling pathways, were associated with titanium exposure in transcriptome and proteome studies. However, the findings regarding epigenetic changes caused by titanium were inconsistent.

Summary: The surface roughness did not significantly affect cellular behavior, but there were slight differences between materials. Cells grown on zirconia dioxide exhibited higher cytotoxic effects, while those on lithium disilicate showed lower inflammation expression.

Summary: The study evaluated the influence of hydrophilicity on the surface integrity of implants after insertion in low-density artificial bone. It was found that implants with hydrophilic surface treatment resulted in more titanium particle release into the bone bed. Surface damage was observed after insertion, mainly in the apical region of the implants.

Summary: The study found that DAE surfaces reduce peri-implant bone loss compared to machined surfaces, with a significant impact in the first year post implant insertion. However, in the long term, this surface treatment did not significantly affect soft tissue and bone maintenance.

Summary: The efficacy of photofunctionalization on commercially available dental implant surfaces in a high-glucose environment was assessed in this study. XPS analysis showed that photofunctionalization altered the implant surface chemistry by reducing surface carbon content. Photofunctionalized discs promoted osteoblastic adhesion, viability, and mineralization in a high-glucose environment. Group 3 exhibited the best osteoblastic adhesion in the medium with increased glucose.
