Special Issue Information

Dear Colleagues,

Advancements in dental materials and technologies have revolutionized modern dentistry, providing improved solutions for complex dental conditions such as dental caries, periodontal diseases, and tooth loss. These innovations feature advanced materials and state-of-the-art techniques that enhance durability, biocompatibility, and aesthetics, along with custom-made implant technologies designed to ensure superior integration and long-term stability. This Special Issue aims to highlight the latest developments and applications of restorative dental materials and implant technologies in clinical and research contexts.

Researchers and practitioners from the fields of dental materials, restorative dentistry, prosthodontics, periodontics, and oral and orthognathic surgery are encouraged to contribute original research, clinical case studies, reviews, and meta-analyses that explore these advancements and their impact on improving patient care and oral health outcomes.

This study evaluated the reliability and inter-examiner agreement of the Implant Stability Test (IST) by Anycheck compared to the established Implant Stability Quotient (ISQ) by Osstell across different bone quality types. Seven dental hygienists with varying experience levels performed stability measurements using both devices on standardized implant models representing hard, normal, and soft bone qualities. Both IST and ISQ demonstrated excellent inter-examiner reliability (ICC > 0.90) across all bone quality types, with strong positive correlations (r > 0.85) between measurements regardless of bone density. No significant differences were found in measurement consistency between examiners with different experience levels for either device. The results demonstrate that IST provides comparable reliability to ISQ for implant stability assessment, with excellent inter-examiner agreement and accessibility for practitioners with varying experience levels. The IST system offers practical advantages including elimination of SmartPeg requirements, reduced abutment manipulation, and simplified measurement protocols, supporting its potential as a reliable and cost-effective alternative to traditional ISQ measurements under standardized experimental conditions.

Abstract
The aim of this study was to assess whether baseline the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the systemic immune-inflammation index (SII), and C-reactive protein (CRP) could predict postoperative outcomes in systemically healthy patients receiving dental implants. A retrospective analysis of 116 [...] Read more.
The aim of this study was to assess whether baseline the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the systemic immune-inflammation index (SII), and C-reactive protein (CRP) could predict postoperative outcomes in systemically healthy patients receiving dental implants. A retrospective analysis of 116 systemically healthy adults receiving dental implants was conducted. To minimise confounding, individuals over 50 years old, smokers, and those with systemic diseases, stage III/IV periodontitis, or current medication use were excluded. Periodontal status was classified as clinically healthy or stable. Baseline CRP and complete blood count-derived indices (NLR, PLR, SII) were recorded preoperatively. The primary outcome was osseointegration (proper versus impaired). Implant success was 95.7% (n = 111), with early implant failure occurring in 4.3% (n = 5). Females exhibited higher PLR values than males (p = 0.041), and SII was higher in periodontally stable patients compared to clinically healthy ones (p = 0.036). In systemically healthy patients, routine preoperative screening based on NLR, PLR, and CRP did not improve prediction of early implant failure, whereas SII demonstrated good, statistically significant discrimination (p = 0.015). These findings emphasise the need for further research to clarify the predictive value of blood inflammatory biomarkers. Full article

Background: Implant surface characteristics have been extensively investigated for their potential influence on osseointegration and peri-implant tissue stability. However, their actual clinical relevance in the prevention and progression of peri-implant diseases remains controversial. This systematic review aimed to synthesize the available clinical and microbiological evidence on the impact of different implant surface characteristics and surface modifications on peri-implant outcomes. Materials and Methods: Conducted according to PRISMA and registered in PROSPERO, an electronic search of PubMed, Scopus, and Web of Science (2015–2025) identified clinical studies assessing associations between implant surface characteristics/modifications and peri-implant clinical, radiographic, microbiological, or biomolecular outcomes. Risk of bias was evaluated using ROBINS-I. Results: Thirteen studies (randomized, controlled, and cohort designs) were included. Most trials reported minimal differences in marginal bone loss and peri-implant parameters across surfaces. Potential advantages were mainly observed during early healing or in compromised bone. Long-term evidence emphasized the predominance of patient- and site-related risk factors. Microbiological outcomes were scarce and heterogeneous. Conclusions: Implant surface modifications appear to exert a limited and context-dependent influence on peri-implant outcomes. Long-term peri-implant health is primarily driven by multifactorial interactions involving host, microbial, and clinical factors rather than surface characteristics alone. Full article
