“The ability to help the edentulous patient is paramount. Our team strives to help as many patients as possible with expedited predictable treatment protocols. Both Trefoil and Zygoma treatment options lend themselves to this. We are able to provide fixed solutions immediately and not have patients limited by removable prostheses.

Surgical procedure

Following removal of the patient’s prior mandibular implants, the three Trefoil Implants were placed in a predetermined position (between the mental foramina) with the aid of different standardized guides and templates. The position of the Trefoil Implants corresponds to the pre-manufactured prosthetic bar of the Trefoil system.

Restorative procedure

Following the successful restoration of the mandible with the Trefoil system, the patient sought a fixed prosthesis for the maxilla. The moderate-to-severe bone resorption and an unfavorable maxillary ridge form necessitated the use of NobelZygoma implants in the posterior. These were combined with NobelActive implants in the anterior for hybrid All-on-4® treatment concept (left).
