Figure 1. Cone-beam computerized tomography scan showing the bone destruction around the zygomatic implant at the position of the upper right first molar. The presence of sinusitis and oroantral communication could be also observed. Figure 2. Preoperative clinical photographs showing the presence of mucosal fenestration exposing part of the zygomatic implant and an inflamed peri-implant mucosa with puss discharge. Figure 3. Clinical photograph showing the presence of crater-like bone defect and the presence of granulation tissue. Plaque-like deposits were evident on the implant surface. Figure 4. The insertion of extractor into the implant connection to transmit the counter-torque force to the implant.

Figure T. The extracted zygomatic implants. Figure 6. Clinical image shows remaining bone defect and the effectiveness of the counter-torque technique in preserving the available bone tissue. The explantation alveolus permitted the surgical debridement of the chronic sinusitis. Figure 7. A radiograph showing the placement of the provisional prosthesis for the immediate loading of the dental implant. Figure 8. The definitive implant-supported prosthesis after 6 months of surgery.
