The rapid integration of clear aligners into orthodontic practice has encouraged the advancement of biomechanical materials aimed at enhancing treatment efficiency. The mechanical behavior of these materials is a crucial factor in their clinical success and reliability. This study examines the Young’s modulus of Clear-Blokker® (Scheu Dental), a photopolymerizable resin utilized as an attachment material for clear aligners, and analyzes its mechanical response under varying curing durations (5 s and 10 s) and environmental settings (dry storage versus immersion in artificial saliva at 37 °C). Forty-eight cylindrical samples were fabricated and tested under quasistatic compression after a 14-day period. A multifactorial analysis of variance (ANOVA) was performed at a 5% significance threshold to assess variance differences. Samples immersed in artificial saliva demonstrated a statistically significant reduction in Young’s modulus compared with those stored in dry conditions (p = 0.0213). However, curing duration did not show a significant influence. Findings indicate that Clear-Blokker® exhibits mechanical behavior comparable to conventional clear aligner materials, making it a suitable adjunct for orthodontic biomechanics. Nonetheless, additional long-term clinical investigations are needed to validate its durability and effectiveness in the oral environment.
