In implantology, PLGA-based systems have emerged as versatile platforms for scaffolds, coatings, and localized drug delivery, aimed at enhancing osseointegration and tissue regeneration. This review provides a focused and up-to-date analysis of PLGA applications in dental and orthopedic implantology, with particular emphasis on advances reported over the past decade. Unlike previous reviews that predominantly address general drug delivery or broad tissue engineering applications, this work establishes a direct correlation between polymer composition (LA:GA ratio), processing strategies, and biological outcomes, including degradation behavior, mechanical performance, and host response. Special attention is given to multifunctional PLGA systems incorporating antibiotics, growth factors, and bioactive nanoparticles, highlighting their role in improving antibacterial efficacy and osteogenesis. Emerging technologies such as nanostructured composites, additive manufacturing, and stimuli-responsive delivery platforms are critically evaluated. Key limitations\u2014including acidic degradation by-products, burst release kinetics, and translational barriers\u2014are discussed in the context of clinical applicability. By integrating physicochemical design with biological performance and recent clinical trends (2024\u20132025), this review proposes a framework for the rational development of next-generation PLGA-based implant systems.<\/jats:p>","DOI":"10.3390\/polym18091113","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T13:32:21Z","timestamp":1777555941000},"page":"1113","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Poly(Lactic-Co-Glycolic Acid)-Based Systems in Implantology: Advances in Biomaterial Design, Drug Delivery, and Tissue Regeneration"],"prefix":"10.3390","volume":"18","author":[{"given":"Bogdan Alexandru","family":"Popescu","sequence":"first","affiliation":[{"name":"Doctoral School, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5318-1250","authenticated-orcid":false,"given":"Ionela","family":"Belu","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Technique, Faculty of Pharmacy, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9356-6593","authenticated-orcid":false,"given":"Andreea Gabriela","family":"Mocanu","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Technique, Faculty of Pharmacy, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Viorica","family":"Cioc\u00eelteu","sequence":"additional","affiliation":[{"name":"Department of Instrumental and Analytical Chemistry, Faculty of Pharmacy, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1523-9116","authenticated-orcid":false,"given":"Daniela","family":"Calina","sequence":"additional","affiliation":[{"name":"Department of Clinical Pharmacy, Faculty of Pharmacy, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4261-1497","authenticated-orcid":false,"given":"Costel Valentin","family":"Manda","sequence":"additional","affiliation":[{"name":"Department of Instrumental and Analytical Chemistry, Faculty of Pharmacy, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johny","family":"Neam\u021bu","sequence":"additional","affiliation":[{"name":"Department of Physics, Faculty of Pharmacy, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1815-780X","authenticated-orcid":false,"given":"Oana Elena","family":"Nicolaescu","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Technique, Faculty of Pharmacy, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreea-Cristina","family":"Stoian","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreea Silvia","family":"P\u00eervu","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Medicine, University of Medicine and Pharmacy of Craiova, 2 Petru Rare\u015f Street, 200349 Craiova, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Prasad, K., Bazaka, O., Chua, M., Rochford, M., Fedrick, L., Spoor, J., Symes, R., Tieppo, M., Collins, C., and Cao, A.
