Pneumatic extrusion-based bioprinting is a recent and interesting technology that is very useful for biomedical applications. However, many process parameters in the bioprinter need to be fully understood in order to print at an adequate resolution. In this paper, a simple yet accurate mathematical model to predict the printed width of a continuous hydrogel line is proposed, in which the resolu...

Interdisciplinary care for the management of impacted teeth provides a holistic method of treating patients. Careful planning is necessary to reach the desired treatment goals. This article attempts to highlight the importance of diagnosis and adequate treatment planning for successful eruption of impacted teeth. The concept of forced eruption to improve the bone morphology of the impacted teet...

• While the safety and efficacy of Gore-Tex in vocal fold medialization surgeries has been wellestablished, various complications have also been seen, including prolonged hospital observation, infection, extrusion, dyspnea, and bleeding.1 The incidence of implant extrusion for all types of implants has been reported to be as high as 8.6% in earlier series;2 however, larger and more recent studi...

Although sodium hypochlorite is the most frequently used canal irrigant during endodontic treatment, its complications are not as well recognized as its effectiveness. This report demonstrates that sodium hypochlorite extrusion during endodontic treatment can cause severe complications. A 5-year-old boy experienced immediate pain and swelling, ecchymosis in surrounding tissues, and profuse blee...

Ventriculoperitoneal (VP) shunt is the most commonly performed procedure for the management of hydrocephalus. VP shunt related complications remain a persistent problem in clinical practice. However, extrusion of components of shunt apparatus is very rare. Extrusion of ventriculo-peritonea l(VP) shunt catheter is an unusual complication of ventriculoperitoneal shunt Surgery. The authors report ...

The meniscus roots are critical for meniscus function in preserving correct knee kinematics and avoiding meniscus extrusion and, consequently, in the progression of osteoarthritis. Several techniques exist for medial meniscus posterior root tear repair; however, current surgical techniques have been proved to fail to reduce meniscus extrusion, which has been shown to be associated with developm...

blends of sorghum and soybean flours were processed in a co-rotating twin screw extruder to prepare expanded product. response surface methodology (rsm) was used to study the effect of soya level (sl), feed moisture (fm), barrel temperature (bt) and screw speed (ss) on extruder system parameters and physical properties of the extrudate. response variables were product temperature (pt), motor to...
