Excellent STI prevents the peri-implant hard and soft tissues from being disturbed by bacteria and other external stimuli. However, peri-implant STI is weaker and more susceptible to damage than natural teeth, which may increase the incidence of peri-implant disease. The surface properties of materials in the gingival region of dental implants play a crucial role in modulating the biological response of the surrounding soft tissues. Therefore, different surface modifications have been made to enhance peri-implant STI. This review provides an in-depth analysis of the challenges of STI around dental implants, comprehensively reviews the effects of different implant/abutment modification strategies, including materials, surface characteristics, coatings, summarizes the availability and limitations of the current research, suggests possible future directions to provide feasible ideas for exploring the most optimal implant/abutment design to increase STI, and provides a reference for the clinical translation of the surface modifications to dental implants.</p>","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 11","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144245115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These included lowering the annealing temperature, compensating for material loss, as well as depositing a diffusion barrier between the substrate and NMC film.

This study employed tip-enhanced Raman spectroscopy (TERS) and density functional theory (DFT) simulations to explore this CO<sub>2</sub> chemisorption.

Height scans of hydrothermally treated (100) SrTiO<sub>3</sub>, show values closer to 0.3 and 0.1 nm, where we attribute the difference in height to the selective adsorption of ambient CO<sub>2</sub> on one of the terminations. The TERS analysis shows the presence of a 1071 cm<sup>−1</sup> Raman peak (characteristic of carbonate vibration), localized exclusively at the SrO terrace, confirming that CO<sub>2</sub> preferentially adsorbs onto SrO. Both experimental and DFT results indicate that this CO<sub>2</sub> monolayer alters the binding energy between the SrO and TiO<sub>2</sub> terminations.
