OBJECTIVE : This retrospective study evaluated treatment with individually contoured molded bracing at early stages of the disease. METHODS : We evaluated the medical records of patients undergoing treatment of Blount's disease with molded orthoses for medial decompression between 2010 and 2014. The deformity angle (Drennan's metaphyseal-diaphyseal angle) and Langenskiöld classification were ...

The aim of this study was to investigate vacuum forming techniques for reduction of loss in mouthguard thickness effects of sheet grooving and thermal shrinkage of extruded sheets on molded mouthguard thickness. Mouthguards were fabricated with ethylene vinyl acetate (EVA) sheets (4.0 mm thick) using a vacuum forming machine. Sheet form was a convexing v-shaped groove toward the back, 10-40 mm ...

Background: Identifying of ethical dimensions in educational technology can be effective in improving the ethical climate in the area of educational technology. Therefore, this research has been done to identify the ethical dimensions of technology. Method: The present study was mixed. In the qualitative part, the content analysis method was used. The statistical population included upstream d...

In this paper, we are focusing on comparing results obtained for polymer elements manufactured with injection molding and additive manufacturing techniques. The analysis was performed fused deposition modeling (FDM) single screw regards to the standards used in thermoplastics processing technology. We argue that cross-section structure of sample via FDM is key factor fabrication high-strength c...

The compression molding process of sheet compound (SMC) is an economical manufacturing for lightweight parts. However, defects, such as fiber matrix separation, and re-orientation, may develop during the in confined regions, ribs bosses. Hence, mechanical properties composite depend on local architecture. Consequently, this work compares predictive capabilities tensor-based directly modeled sim...

3D printing has been used for teaching purposes. Creating models simulating surgeries. Gong et al presented a workflow digital planning surgery and Rendon previously low-cost method with acceptable precision. This paper aims to present case where surgical was applied bone graft shape dimensions. A 16-year-old female patient history of bilateral cleft lip palate received 6 interventions treat he...

Abstract The direct ink writing (DIW) method of 3D-printing liquid resins has shown promising results in various applications such as flexible electronics, medical devices, and soft robots. A cost-effective extrusion system for a two-part high-viscous resin is developed this article to fabricate immensely stretchable structures. static mixer capable evenly mixing two viscous an extremely low fl...
