Anatomical Bases for the Insertion of Zygomatic Implants

Abstract: When the angle of installation of the additional implant is less than 25 degrees and that of the conventional zygomatic implant is less than 39 degrees , perforation of the maxilla, zygoma, or the infratemporal fossa must be avoided. When the angle of installation of an additional implant is greater than 47 degrees and that of the conventional zygomatic implant is greater than 62 degrees , perforation of the orbital floor must be avoided. The length of an additional implant was greater than the length of a con… Show more

“…Two points namely E 1 and E 2 were additionally designated. Point E 1 was the lowermost point of the alveolar crest, drawing a line from the lateral margin of the nasal incisure shifted 5 mm to the palatal side, corresponding to the coronal point for the anterior zygomatic implant in the quad approach (Figure D). Point E 2 was the lowermost point of the alveolar crest, drawing a line at a tangent to the lateral margin of the infraorbital foramen shifted 5 mm to the palatal side, corresponding to the coronal point for the posterior zygomatic implant (Figure D).…”

“…Loss of teeth leads to bone atrophy of the alveolar crest up to 1/3 of the original height within a few weeks after extraction. In the following years, atrophy progresses both from the crest and the sinus as a result of invasive proliferation of the maxillary sinus mucosa …”

“…Em relação aos procedimentos de aumento de rebordo ósseo, implantes zigomáticos são menos traumáticos e demandam menor tempo de tratamento (ROSSI et al, 2008;SEVETZ, 2006), por serem realizados em apenas uma etapa cirúrgica, não necessitando de qualquer outro procedimento (BEDROSSIAN et al, 2002).…”

“…Atravessam o seio maxilar, ao longo da parede lateral, perto da crista zigomáticoalveolar, e seus ápices perfuram a porção cortical do osso zigomático, próximo ao ângulo entre o arco zigomático e o processo frontal (BEDROSSIAN et al, 2002;DUARTE et al, 2004;KATO et al, 2005;KOSER;MENDES, 2006;ROSSI et al, 2008;SEVETZ, 2006;UCHIDA et al, 2001). A estabilidade do suporte ósseo para o implante zigomático depende do quão bem a parte apical do implante se envolve com o osso zigomático (UCHIDA et al, 2001).…”
