EZgoma® – Zygomatic Guided Technology enabling a quick precise minimally invasive Extra Maxillary and Intra Sinus drilling protocol execution for Zygomatic implants placement as well as Pterygoid and regular implants.
All components, Implants, and Prosthetics are directed by the guide to an accurate pre-determined position and orientation.


Introduction

Bone resorption of the alveolar processes is a major problem in edentulous and semi edentulous patients. It is considered a chronic, progressive, and irreversible process in all patients.

Numerous bone augmentation methods have been described, but most of them need two-step surgical procedures with relatively high rates of resorption or failure. So, Zygomatic implants placement considered a solution for these patients.

Noris Medical Zygomatic implant is specially designed for the extra-maxillary technique. Noris instrumentation greatly simplifies the implant placement and protects the sinus membrane.  High torque is consistently achieved, which allows immediate placement of a screw-retained prosthesis.

Moreover, Zygomatic Guided Technology (EZgoma®) enables a quick, precise and minimally invasive Extra Maxillary and Intra Sinus drilling protocol execution for Zygomatic implants placement as well as Pterygoid and regular implants.

As a result of the introduction of computer software technology, that integrates the information from various 3D imaging tools, we got a major revolution in virtual implant treatment planning that takes into consideration both surrounding vital anatomic structures and prosthetic requirements.

Noris Medical EZgoma® technology, based on computer software, provides us an appropriate prosthetic platform position that enhances the restoration result.

Clinical case

70 years old female with controlled high blood pressure.

Presents partial edentulous maxilla, with severe bone resorption, and tooth mobility due to periodontal disease and infections.

After radiological and CBCT assessments it was decided to extract all the remaining teeth followed with immediate implantation and immediate restoration. The surgical plan is to install a bilateral Pterygoid implant, 3 Zygomatic implants (two on the right side and one on the left side), and 3 regular implants.
