The main differences between glass-ceramic and cast porcelain are:
1. Material composition: Glass-ceramic consists of a glass matrix and crystals, while cast porcelain is a pure ceramic material. The latter has a more natural color but slightly lower strength.
2. Processing technology: Glass-ceramic is manufactured using computer-aided design, resulting in fast and precise processing; cast porcelain requires multiple processes, making production complex and time-consuming.
3. Performance characteristics: Glass-ceramic has high strength and is suitable for posterior teeth, while cast porcelain offers better aesthetics but is more brittle and suitable for anterior tooth restorations.
