A New Surgical and Technical Approach in Zygomatic Implantology

Abstract

The surgical procedures and the zygomatic implant design reduce remarkably the serious post-operative sequelae due to the intrasinus path of the zygomatic fixtures.

Clinical outcome of 302 zygomatic implants in 110 patients with a follow‐up between 6 months and 7 years

“…The patients were rehabilitated either by only ZIs or by using ZIs in conjunction with conventional dental implants. The presurgical and surgical approach, the prosthetic procedure and the follow‐up protocol were described in detail in a previous article by the same team 14 . The representative preoperative and postoperative orthopantomographic images of one of the patients can be seen in Figures 1 and 2.…”

“…The presurgical and surgical approach, the prosthetic procedure and the follow-up protocol were described in detail in a previous article by the same team. 14 The patients were recalled for clinical follow-up after 10 days, 1 month, and every 3 months for the first year, and then twice a year.…”

Zygomatic implant survival in 9 ectodermal dysplasia patients with 3.5‐ to 7‐year follow‐up

“…ZI is considered as a successful alternative for rehabilitation of patients with severe maxillary atrophy; however, ZI insertion is a major surgery and can represent some risks (Aparicio, Manresa, Francisco, Ouazzani, et al, 2014;Brånemark et al, 2004;Candel-Marti, Carrillo-Garcia, Penarrocha-Oltra, & Penarrocha-Diago, 2012;Chrcanovic & Abreu, 2013;Chrcanovic, Albrektsson, & Wennerberg, 2016;D'Agostino et al, 2016;Grecchi et al, 2017;Goker et al, 2020;Yates et al, 2014). The possible complications of ZI surgery include sinusitis, soft tissue infections, paresthesia, and oroantral fistula, penetration of the orbital cavity during the drilling protocol, and failure of the implants (Filho, Amaral, Curra, dos Santos, & Cardoso, 2016;Maló, Nobre, Lopes, Ferro, & Moss, 2015;Nobre, Maló, & Gonçalves, 2015).…”

El tratamiento con implantes cigomáticos en pacientes con atrofia maxilar severa

“…El diagnóstico del paciente para implantes cigomáticos requiere la valoración de la estructura ósea mediante el examen radiológico 15,19 . En esta investigación en relación a la selección de los pacientes, en una primera fase se realizó una ortopantomografía como medio diagnóstico por imagen para valorar el grado de disponibilidad ósea.…”

“…En los últimos 20 años, se han modificado sustancialmente los procedimientos quirúrgicos de inserción de los implantes cigomáticos 7,11,[14][15] . Además de la via clásica intrasinusal, se ha propuesto la via extrasinusal donde el punto de entrada del implante se realiza mediante una osteotomía en la cresta alveolar y la colocación se realiza externamente a la membrana sinusal 14,16 .…”
