Nanomaterial-based therapies offer a translationally attractive strategy. Nanoscale hydroxyapatite, calcium phosphates, mesoporous silica, metallic nanoparticles, bioactive glasses, polymeric carriers, injectable nanocomposite hydrogels, extracellular vesicle-inspired systems, and nanostructured coatings can act on several targets at once, including osteogenesis, angiogenesis, immune response, antimicrobial activity, mechanical reinforcement, and controlled release. This review synthesizes recent evidence on nanomaterial-enabled bone regeneration for craniomaxillofacial and cranial vault reconstruction, placing emphasis on the pathway from in vitro mechanisms to animal models, additive manufacturing, patient-specific implants, and early clinical translation. 3D-printed calcium phosphate or hydroxyapatite-based patient-specific scaffolds are currently supported by the strongest near-clinical evidence, whilst immunomodulatory, bioprinted, injectable, and drug-delivering nanocomposites remain largely preclinical. Growth-factor-independent strategies based on ionic signaling, dipyridamole-enhanced adenosine signaling, nanosilicate-mediated osteogenesis, Wnt\/beta-catenin mechanotransduction, and nanoparticle-mediated osteoimmunomodulation may reduce reliance on recombinant bone morphogenetic proteins. However, large-animal validation, long-term biodistribution, nanotoxicology, sterilization, manufacturing reproducibility, and regulatory classification remain major barriers. Future clinical translation will require rational scaffold design, anatomical indication-specific testing, antimicrobial integration, and harmonized regulatory evidence packages.<\/jats:p>","DOI":"10.3390\/bioengineering13091014","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T01:05:26Z","timestamp":1788224726000},"page":"1014","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["From Bench to Bone: Translational Pathways of Nanomaterial-Based Therapies in Craniomaxillomandibulofacial and Cranial Vault Reconstruction"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7463-6106","authenticated-orcid":false,"given":"Ioannis","family":"Chatzistefanou","sequence":"first","affiliation":[{"name":"University General Hospital \u201cAttikon\u201d, National and Kapodistrian University of Athens, 12462 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-1703-6980","authenticated-orcid":false,"given":"Sophia","family":"Tsokkou","sequence":"additional","affiliation":[{"name":"Laboratory of Histology-Embryology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-1715-1272","authenticated-orcid":false,"given":"Alexandros C.","family":"Liatsos","sequence":"additional","affiliation":[{"name":"Laboratory of Histology-Embryology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6138-0970","authenticated-orcid":false,"given":"Kyriaki","family":"Papadopoulou","sequence":"additional","affiliation":[{"name":"Laboratory of Histology-Embryology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"},{"name":"Department of Neurosurgery, AHEPA University Hospital, Aristotle University of Thessaloniki, 54636 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgia-Alexandra","family":"Spyropoulou","sequence":"additional","affiliation":[{"name":"Clinic of Plastic and Reconstructive Surgery, Papageorgiou General Hospital, Aristotle University of Thessaloniki, 56429 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasileios","family":"Petsinis","sequence":"additional","affiliation":[{"name":"University General Hospital \u201cAttikon\u201d, National and Kapodistrian University of Athens, 12462 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0709-5407","authenticated-orcid":false,"given":"Theodora","family":"Papamitsou","sequence":"additional","affiliation":[{"name":"Laboratory of Histology-Embryology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"82","DOI":"10.1111\/jcpe.13123","article-title":"Biomaterials and regenerative technologies used in bone regeneration in the craniomaxillofacial region: Consensus report of group 2 of the 15th European Workshop on Periodontology on Bone Regeneration","volume":"46","author":"Sanz","year":"2019","journal-title":"J.
