This study aimed to evaluate ionic release, flexural strength and water absorption of UDMA resins containing 0-30 wt% surface pre-reacted glass-ionomer (S-PRG) filler fabricated by a DLP 3D printer. Release of Al, B, Na, Sr and F ions were measured by inductively coupled plasma (ICP) and an ion meter. Flexural strength test and water absorption measurements were performed according to the International Organization for Standardization (ISO) 4049 standard and ISO 1567 standard, respectively.

Knee osteoarthritis (KOA) is a significant public health concern linked to age-related musculoskeletal issues and is among the conditions contributing to LS. Age-related lower extremity muscle weakness exacerbates knee pain in KOA, but the impact of LS on knee pain is not clear, prompting the present investigation.

This study introduces an innovative approach using compact three-dimensional (3D) printers and computed tomography data to generate segmented body models for traditional Damen corset orthoses. The goals included evaluating the comfort and fit of orthoses and assessing the effectiveness of our approach for prosthetic companies with limited financial resources.
