Challenge

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.

Innovation

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.

Benefits

• 55° optimizes prosthetic versatility
• Machined sections for exposed soft tissue and decreased rotations
• Narrow Apex Available for smaller patients and easier placement

Technical Facts

• External Hex connection with 2.7 width and .7 height
• 55° angle correction
• Zygomatic available in 35mm-60mm
• Oncology available from 27.5mm-47.5mm
• Zygan has a 2.8mm apex
• 4.0mm prosthetics
