ZAGA is more than just a method, it is a philosophy of how we work with patient well-being as one of its core principles. Each patient’s individual characteristics and needs are the main elements considered when designing a treatment plan and deciding what materials or implants will be used.

By anchoring the dental prosthesis to zygomatic implants, the ZAGA philosophy aims to achieve long-term success in treating severe maxillary atrophy. In addition to maximizing success, the ZAGA philosophy seeks to prevent complications instead of treating them. To obtain these objectives through a standardized process, the ZAGA philosophy develops and uses individual, contrasted, and systemized action protocols.
