Zygomatic and Oncology Dental Implants
The longer lengths and 55° restorative platform of Zygomatic and Oncology implants, in the treatment of patients with a severely resorbed maxilla and/or missing maxillary bone, enables zygomatic bone to be utilised and ensures optimal restorative platform emergence.
Following traumatic accidents, oncology resections or congenital defects, patients present with missing sections of bone and connecting soft tissue. These situations can pose significant physical and psychological effects on the patient.
55° Zygomatic Implants were introduced by Southern Implants in 2002 to accommodate a higher angle for the restorative table to be in the arch and not the palate providing prosthetic versatility.
More recently, Southern Implants expanded the 55° Zygomatic Implant range with the Oncology Implant and Zygan® Implant.
The Oncology Implant has a a 15mm threaded apex and a coronal machined surface that can be exposed to soft tissue in oncology resections.
The Zygan Implant features a Narrow-Apex with a smooth mid-section and MSc threaded coronal region. This implant is especially useful in patients with smaller anatomies.
The Zygex Implant offers the same machined area with a narrower apex of 3.4mm.
