The mechanical properties of these materials play a critical role in determining their clinical performance and efficacy. This study investigates the Young\u2019s modulus of Clear-Blokker\u00ae (Scheu Dental), a photopolymerisable resin used for the attachment of clear aligner, and evaluates its mechanical behaviour under different curing times (5 s and 10 s) and environmental conditions (dry storage and immersion in artificial saliva at 37 \u00b0C). Methods: Forty-eight cylindrical specimens were prepared and subjected to quasistatic compression tests after 14 days. A multi-factorial analysis of variance (ANOVA) at a significance level of 5% was performed to compare the variances. Results: The results showed that samples immersed in artificial saliva had significantly reduced Young\u2019s moduli compared to samples stored in dry conditions (p = 0.0213), while no significant difference was observed between curing times. Conclusions: The results suggest that Clear-Blokker\u00ae has mechanical properties comparable to those of clear aligner materials, making it suitable as a biomechanical aid for orthodontic treatment. However, further clinical studies are required to confirm its long-term efficacy in the oral environment.<\/jats:p>","DOI":"10.3390\/dj13020067","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T06:42:36Z","timestamp":1738305756000},"page":"67","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Mechanical Behaviour of Orthodontic Auxiliary Photopolymerisable Resins in Simulated Oral Conditions: An In Vitro Study"],"prefix":"10.3390","volume":"13","author":[{"given":"Riccardo","family":"Favero","sequence":"first","affiliation":[{"name":"Unit of Maxillofacial Surgery, Department of Neurosciences, University of Padua, Via Giustiniani 2, 35121 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tommaso","family":"Zanetti","sequence":"additional","affiliation":[{"name":"Unit of Maxillofacial Surgery, Department of Neurosciences, University of Padua, Via Giustiniani 2, 35121 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3378-3844","authenticated-orcid":false,"given":"Vincenzo","family":"Tosco","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences and Stomatology (DISCO), Universit\u00e0 Politecnica delle Marche, 60126 Ancona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3419-665X","authenticated-orcid":false,"given":"Riccardo","family":"Monterubbianesi","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences and Stomatology (DISCO), Universit\u00e0 Politecnica delle Marche, 60126 Ancona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4411-3333","authenticated-orcid":false,"given":"Andrea","family":"Volpato","sequence":"additional","affiliation":[{"name":"Unit of Maxillofacial Surgery, Department of Neurosciences, University of Padua, Via Giustiniani 2, 35121 Padua, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"276.e1","DOI":"10.1016\/j.ajodo.2008.07.011","article-title":"Attractiveness, acceptability, and value of orthodontic appliances","volume":"135","author":"Rosvall","year":"2009","journal-title":"Am.
