Full-Arch Rehabilitation Of Post-Mucormycosis Edentulous Maxilla Using Quad Zygomatic Implants: A Clinical Case Report, Akansha Bansod, Sweta Kale Pisulkar, Arushi Beri, Mony Behera, Pragya Manushree, Utkarsh Umre, Michael Subal Pramanik

International Arab Journal of Dentistry

Rehabilitating the maxilla in the patient who has had surgical resection for mucormycosis poses a distinctive set of anatomical, surgical, and prosthetic challenges. The extensive maxillary bone loss after aggressive debridement often makes traditional implant-supported prosthetic options impossible. In these circumstances, zygomatic implants have proven to be a predictable, graftless solution, especially in patients with extremely atrophic maxillae. Where the bone loss is severe, the quad zygoma procedure—two implants for each zygomatic arch—is possible to support full arch rehabilitation with a fixed prosthesis. This report presents the successful rehabilitation of oral function and appearance in a patient with post-mucormycosis edentulous …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Three Cheers For Print!, Jillian Lacross

AADEJ - The Communicator

This guest feature argues that print magazines are a worthwhile and necessary investment for associations, focusing on the three pillars of expectation, engagement, and experience. Print publications establish trust because they imply an inherent vetting process; affluent consumers trust print magazines the most, and print advertisements are significantly more trusted than social media ads. Print provides a respite from digital fatigue, with Worldmetrics finding that readers spend an average of 41 minutes engaging with a printed magazine, far exceeding the 3 to 7 minutes typically spent online. Printed materials enhance retention, recall, and emotional processing, strengthening the association's brand. Ultimately, …
