Gold Karat in Dentistry: Understanding Dental Applications
"Ney majority" and "Miracast" are not dental terms.
- Ney likely refers to Dentsply Sirona's Ney brand of dental alloys (gold-based casting alloys for crowns/bridges).
- Miracast is a wireless display standard (screen mirroring)—unrelated to dentistry.
