Acrylic prosthesis fractures are commonly observed in prosthodontic practice and have not been reliably resolved. This study compared the resistance to masticatory force of acrylic bases of removable complete conventional prosthesis in 3D upper models. Forty acrylic base test specimens containing two types of reinforcement meshes (20 with glass fiber meshes (FIBER-FORCE\u00ae- Synca, Bio Composants M\u00e9dicauxTM, Tullins, France), 20 with metal meshes (DENTAURUM\u00ae-Ispringen, Germany)), 20 with a conventional PMMA acrylic base (LUCITONE 199\u00ae-Dentsply Sirona, York, PA, USA), and 20 using a permanent soft reline material (MOLLOPLAST-B\u00ae-DETAX GmbH &amp; Co. KG, Ettlingen, Germany) were tested\u2014a total of 80 specimens. Half of the specimens were made for a low alveolar ridge and half for a high alveolar ridge. The data were analysed using one-way analysis of variance and Student\u2019s t-test for independent test specimens. In the high-alveolar-ridge group, the prosthesis reinforced with the glass fiber mesh was the most resistant to fracture, while in the low-alveolar-ridge group, the non-reinforced prosthesis showed the highest resistance masticatory force. Prostheses with the permanent soft reline material showed the lowest resistance to fracture in both high and low-alveolar-ridge groups. The results show that the selection of the right reinforcement material for each clinical case, based on the height of the alveolar ridge, may help to prevent prosthesis fractures.<\/jats:p>","DOI":"10.3390\/ma14123308","type":"journal-article","created":{"date-parts":[[2021,6,15]],"date-time":"2021-06-15T11:00:33Z","timestamp":1623754833000},"page":"3308","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Comparison of the Masticatory Force (with 3D Models) of Complete Denture Base Acrylic Resins with Reline and Reinforcing Materials"],"prefix":"10.3390","volume":"14","author":[{"given":"Catarina","family":"Calamote","sequence":"first","affiliation":[{"name":"Department of Oral Rehabilitation, Instituto Universit\u00e1rio de Ci\u00eancias da Sa\u00fade, 4585-116 Gandra, Portugal"}]},{"given":"Isabel Carolina","family":"Coelho","sequence":"additional","affiliation":[{"name":"Department of Oral Rehabilitation, Instituto Universit\u00e1rio de Ci\u00eancias da Sa\u00fade, 4585-116 Gandra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1718-0744","authenticated-orcid":false,"given":"Ant\u00f3nio S\u00e9rgio","family":"Silva","sequence":"additional","affiliation":[{"name":"Dental Science Department, Instituto de Investiga\u00e7\u00e3o e Forma\u00e7\u00e3o Avan\u00e7ada em Ci\u00eancias e Tecnologias da Sa\u00fade, Rua Central da Gandra 1317, 4585-116 Gandra, Portugal"}]},{"given":"Jos\u00e9 Lu\u00eds","family":"Esteves","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8426-6871","authenticated-orcid":false,"given":"Lu\u00eds","family":"Moreira","sequence":"additional","affiliation":[{"name":"RECI\u2013Research in Education and Community Intervention, Escola Superior de Sa\u00fade Jean Piaget, 4405-678 Vila Nova de Gaia, Portugal"}]},{"given":"Ant\u00f3nio Correia","family":"Pinto","sequence":"additional","affiliation":[{"name":"Department of Oral Rehabilitation, Instituto Universit\u00e1rio de Ci\u00eancias da Sa\u00fade, 4585-116 Gandra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4585-4953","authenticated-orcid":false,"given":"Mar\u00eda Cristina","family":"Manzanares-C\u00e9spedes","sequence":"additional","affiliation":[{"name":"Department of Pathology and Experimental Therapy, Faculty of Odontology, University of Barcelona, 08007 Barcelona, Spain"}]},{"given":"Tom\u00e1s","family":"Escu\u00edn","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation and Maxillofacial Prostheses, Faculty of Odontology, University of Barcelona, 08007 Barcelona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"318","DOI":"10.1016\/S0022-3913(99)70276-3","article-title":"Flexural properties of acrylic resin polymers reinforced with unidirectional and woven glass fibers","volume":"81","author":"Vallittu","year":"1999","journal-title":"J.
