A three dimensional finite element model of the mandible, incorporating cortical and trabecular bone as well as mucosal tissue, was developed based on CBCT data. In the All\u2010on\u2010Four configuration, two anterior implants were placed axially and two posterior implants were tilted distally at 30\u00b0. The All\u2010on\u2010Six model featured axially placed anterior implants, with posterior implants angled at 15\u00b0 in the premolar and 30\u00b0 in the molar regions. Multi\u2010unit abutments were used for all implants. Frameworks were digitally designed in a Toronto prosthesis configuration using each material, and a monolithic zirconia superstructure was applied as the veneering material. All models were subjected to a simulated vertical masticatory load of 150\u2009N. Maximum principal stress values were assessed in the peri\u2010implant bone, while von Mises stress distributions were analyzed in the framework, implants, and fixation screws.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The highest stress accumulation was observed in the All\u2010on\u2010Four configuration, particularly around the cantilever region and distal implants. Materials with low elastic modulus (PEEK and PEKK) caused higher stress transmission to peri\u2010implant bone and connection components. In contrast, rigid materials (titanium and zirconia) provided a more balanced load distribution and resulted in lower stress concentrations. Glass fiber\u2010reinforced composite frameworks (Trilor and Trinia) remained within clinically acceptable biomechanical limits.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The findings of this study indicated that both implant configuration and framework material properties play a critical role in the biomechanical performance and long\u2010term success of the prosthesis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/cre2.70277","type":"journal-article","created":{"date-parts":[[2026,1,26]],"date-time":"2026-01-26T21:14:33Z","timestamp":1769462073000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Biomechanical Evaluation of Framework Materials in All\u2010on\u2010Four Versus All\u2010on\u2010Six Prostheses: A Finite Element Study"],"prefix":"10.1002","volume":"12","author":[{"given":"Lala","family":"Cabbarova","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry Necmettin Erbakan University Konya Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali R\u0131za","family":"Tun\u00e7demir","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Dentistry Necmettin Erbakan University Konya Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4506-8506","authenticated-orcid":false,"given":"Reza","family":"Mohammadi","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry Necmettin Erbakan University Konya Turkey"},{"name":"Faculty of Medicine, Department of Oral and Maxillofacial Diseases University of Helsinki Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,1,26]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.11607\/jomi.3418"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0042-1749363"},{"key":"e_1_2_13_4_1","first-page":"662","article-title":"A Review of the Functional and Psychosocial Outcomes of Edentulousness Treated With Complete Replacement Dentures","volume":"69","author":"Allen P.
