Implant dentistry, while transformative for tooth replacement, often relies on techniques that can be imprecise, operator-dependent, and prone to complications. Dynamic Navigation (DN), a real-time computer-assisted technology, offers a promising solution by enhancing accuracy, reducing errors, and supporting minimally invasive procedures. This narrative review explores how DN can improve clinical precision, reduce surgical complications, and make implantology more accessible and cost-effective. It introduces the DN-PUBLIC framework-a strategic, public health-focused approach for integrating DN into broader healthcare systems, with a strong alignment to the United Nations Sustainable Development Goals (SDGs).A comprehensive review of current literature was conducted, assessing DN's impact on surgical safety, recovery outcomes, cost-efficiency, and its growing role in dental education. The findings highlight that DN significantly improves implant placement accuracy and reduces risks such as nerve injury or misalignment. By allowing for flapless procedures and better soft tissue preservation, DN leads to quicker recovery and greater patient comfort. Beyond clinical outcomes, DN enables general practitioners to perform complex procedures more confidently, expanding access to quality care in underserved regions. Economic analyses also suggest reduced operative time, fewer complications, and lower healthcare costs. In conclusion, DN has the potential to transform public oral health by improving outcomes, training, and access. The DN-PUBLIC framework offers a clear roadmap to guide ethical, inclusive, and sustainable integration of DN technology in dental practice worldwide.</p>","PeriodicalId":94016,"journal":{"name":"Frontiers in oral health","volume":"6 ","pages":"1598206"},"PeriodicalIF":3.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12106405/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanisms underlying this link are not fully elucidated. It has been demonstrated that the Wnt/β-catenin pathway is key to the transformation of oral potentially malignant disorders (OPMD) towards OSCC (i.e., leukoplakia), particularly in OPMD histologically diagnosed as oral dysplasia. Using a GEO database of oral carcinogenesis (GSE85195), the transcriptional modification of 19 Wnt ligands and 4 key regulatory proteins of β-catenin, including E-cadherin, APC, AXIN and GSK3B, during leukoplakia, and early and late stages OSCC, was determined. The transcriptional expression of these targets was also assessed in periodontitis (GEO database GSE223924).
