From: Round and flat zygomatic implants: effectiveness after a 1-year follow-up non-interventional study
a Virtual planning for an anterior zygomatic implant in an anterior maxilla ZAGA Type 4. The amount of residual alveolar bone is insufficient to host the implant. In order to respect sinus lining integrity at the ZICZ, the implant path has been buccally shifted. b Clinical picture illustrating the depth measurement of the minimally invasive ZAGA osteotomy. Note the aiming for an under-preparation preserving as much bone as possible on both sites alveolar and maxillary wall. c The anterior ZAGA-Flat implant is already in place. Note the micro-threads on the implant neck opposite the flat surface. Apical self-cutting flutes help the tapered apical portion of the implant to achieve full primary stability. d 3 and 2-D images of the implant described in (a)–(e) one year later. Sinus integrity has been respected. e Esthetic prosthetic result of the upper rehabilitation and trial of the lower jaw. (Rehabilitation performed by Drs. Pedro Guitian and Elena López ZAGA Center Vigo Spain.)
