The Science behind the ZAGA Concept

Discover the origins of the ZAGA Concept, as well as all peer-reviewed publications supporting it. From the first book by Dr. Carlos Aparicio to collaborative studies with the network of ZAGA Centers.

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.

Zygomatic Implants A New Surgical Approach

2006-2010

The group led by Dr. Carlos Aparicio published in 2006 a first report summarizing their initial one-year experience with the extra-maxillary technique (Ouazzani W, Arevalo J, Sennerby L, Lundgren S, Aparicio C. Zygomatic implants. A new surgical approach. J Clin Perio. 2006;33: supplement [second part]:128). Subsequently, in 2008, as a continuation of that prospective study, the same group reported the three-year follow-up (Aparicio C, Ouazzani W, Aparicio A, Fortes V, Muela R, Pascual A, Codesal M, Barluenga N, Manresa C, Franch M. Extra sinus zygomatic implants: three-year experience from a new surgical approach for patients with pronounced buccal concavities in the edentulous maxilla. Clin Implant Dent Relat Res. 2010;12(1):55-61. doi:10.1111/j.1708-8208.2008.00130.x. Epub 2008 Dec 3. PMID: 19076181).

It is also noteworthy that, in 2006, the group of Dr. Reginaldo Migliorança published in Portuguese, in a non-indexed Brazilian journal, their experience placing zygomatic implants using an exteriorized technique (Migliorança et al. Exteriorização de fixações zigomáticas em relação ao seio maxilar: uma nova abordagem cirúrgica. Implant News. 2006;3(1):30).
