TÉCNICA DE FIXAÇÃO ZIGOMÁTICA EM IMPLANTODONTIA: PILAR Z NA TÉCNICA FACCO

Abstract

Edentulous individuals experience overall health and oral health issues due to the disruption of the stomatognathic system homeostasis, speech difficulties, and dissatisfaction with aesthetics. Implant-supported complete dentures are an excellent alternative for the rehabilitation of these individuals. However, the maxilla poses challenges for rehabilitation with conventional implants due to low bone density, with limited anchoring areas only in the zygomatic bone region. In this context, the proposed treatment for patients with atrophic maxilla involves implants with zygomatic fixations. The first technique was developed in 1998 and became known as conventional. This approach underwent variations over the years with the aim of making it more anatomical and prosthetic, leading to the development of the sinus lift and the exteriorized techniques. In this regard, a Brazilian implantologist in 2021 developed the facco technique to minimize the execution difficulty of the previous ones, aiming to be less invasive and allowing for safer and more predictable treatments. This study conducted a literature review on the use and effectiveness of the new approach of zygomatic fixation in implantology, specifically the Pilar Z in the facco technique, for the rehabilitation of atrophic and edentulous maxillae. The conclusion is that this procedure exhibits good biomechanical behaviors; however, further well-defined clinical and laboratory studies are necessary for its consolidation.
