Remote implant anchorage for the rehabilitation of maxillary defects

Zygoma implant-supported prosthetic rehabilitation after partial maxillectomy using surgical navigation: A clinical report

“…36 Since then several reports have been published on the clinical performance of zygoma implants. 28,29,31,35,[37][38][39][40][41][42][43][44][45][46] The 2 primary indications for the use of zygoma implants are atrophic edentulous maxillae and defects after maxillary resection. 28,29,40 Zygoma implants are generally placed at a 30 to 60-degree angle relative to the occlusal plane.…”

“…[24][25][26][27] Because of the limited amount of remaining maxillary bone following maxillectomy, implant placement for anchoring a prosthesis has also been performed in more remote sites such as the zygomatic bone. [28][29][30][31][32][33][34][35] The zygoma implant (Zygomaticus fixture; Nobel Biocare, Göteborg, Sweden) developed by Branemark was specifically designed to offer maximum bone anchorage while simplifying access to the implant head, facilitating the abutment connection. 36 The zygoma implant is available in 8 lengths ranging from 30 to 52.5 mm.…”

“…All-on-4 tekniğinde kullanılan eğimlendirilmiş distal implantların protetik altyapı olarak kullanımı yük dağılımına negatif olarak yansı-mamaktadır. 14,15 Eğimlendirilmiş distal implant poste- 22 Bu durumun arka bölgelerde yükün uygulanma doğrultusunun daha dik, ön bölgelerde ise daha oblik olduğu için ortaya çıktığı düşünülmektedir. 25 All-on-4 uygulanabilirliği ve güvenirliği kabul edilmiş bir tedavi şeklidir.…”

Endoscopically-Assisted Zygomatic Implant Placement: A Novel Approach

“…Several approaches for ZI insertion have been reported, such as the classical approach (known as Brånemark approach) [11] the sinus slot technique [15] and the exteriorized approach [16]. By the first two modalities, an osteotomy is performed at the lateral aspect of the sinus wall to get access into the sinus cavity.…”

“…An inverted Langenbeck retractor placed subperiosteally is useful to lift the soft tissue around the zygomatic bone and to allow a direct visualization of the most lateral aspect of the malar bone. According to the classical description by Brånemark for the insertion of ZIs [11], a 1-cm antrostomy is performed in the lateral aspect of the maxillary sinus wall with a round bur, and further gross retraction of the Schneiderian membrane is performed, although membrane perforation or disruption does not constitute a problem.…”
