Sixty extracted human teeth (thirty molars and thirty premolars) were restored using three different fabrication methods: 3D-printed resin restorations, fiber mesh-reinforced direct composite restorations, and indirect composite restorations. Color stability was assessed using a spectrophotometer, and fracture resistance was measured using a universal testing machine. Finite element stress analysis (FEA) was conducted to validate mechanical test results under simulated intraoral conditions. The fiber-reinforced composite group exhibited the highest fracture resistance (1057.91 MPa), while 3D-printed restorations showed the lowest (p &lt; 0.05). Regarding color stability, the fiber-reinforced group demonstrated the highest \u0394E00 values (\u0394E00 = 1.71), differing significantly from the other groups, while the 3D-printed and indirect composite restorations showed no significant difference. Mechanical test results were consistent with FEA findings. These results indicate that fiber reinforcement enhances mechanical durability in high-load-bearing areas, while 3D-printed restorations may not yet be suitable for posterior regions. However, their potential use in anterior restorations, where occlusal forces are lower, warrants further investigation to improve material properties.<\/jats:p>","DOI":"10.3390\/polym17101340","type":"journal-article","created":{"date-parts":[[2025,5,14]],"date-time":"2025-05-14T12:22:17Z","timestamp":1747225337000},"page":"1340","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["In Vitro Evaluation of the Mechanical Properties of Posterior Adhesive Restorations Fabricated Using Three Different Techniques"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2502-2698","authenticated-orcid":false,"given":"Cem","family":"Peskersoy","sequence":"first","affiliation":[{"name":"Department of Restorative Dentistry, Faculty of Dentistry, Ege University, 35040 Izmir, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gozde","family":"Acar","sequence":"additional","affiliation":[{"name":"Department of Restorative Dentistry, Faculty of Dentistry, Ege University, 35040 Izmir, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"198","DOI":"10.17796\/1053-4628-39.3.198","article-title":"Meta-analysis of observational studies on the most commonly missing permanent dentition (excluding the third molars) in non-syndromic dental patients or randomly-selected subjects, and the factors affecting the observed rates","volume":"39","author":"Rakhshan","year":"2015","journal-title":"J.
