Immediate stabilization at stage II of Zygomatic implants: Rationale and technique

The severely resorbed maxilla presents a challenge for the maxillofacial surgeon and the restorative dentist planning implant restorations. The Zygomatic implant, as introduced by Branemark, allows for the surgical placement of implants to restore resorbed maxillae without major grafting procedures. A minimum of 2 implants in the anterior maxilla are used in conjunction with 1 implant in each zygoma to support a prosthesis. Fabricating a passive bar to connect the implants at phase II surgery may require 1 to 2 days. With the adhesive abutment cylinder luting technique, a rigid framework can be delivered within 1 hour of uncovering the implants. This approach saves considerable time over conventional techniques and allows for the restoration of severely resorbed maxillae in an efficient and routine manner. The technique also eliminates the necessity for a technician to be available on-site for the procedure.
