Active Implant Periapical Lesions Leading to Implant Failure: Two Case Reports
Implant periapical lesion (IPL), an inflammatory lesion surrounding the apex of a dental implant, has been previously reported as a possible cause for implant failure. This article describes 2 successive cases of active IPL that were diagnosed early by clinical signs and radiologic findings. Lesions were treated surgically with implant removal and debridement. The etiology, findings, and treatment approaches for IPL are discussed in comparison with other reports.
Figure 1. Case 1: Panoramic x-ray view immediately after dental implant placement. Figure 2. Case 1: Panoramic radiograph showing radiolucencies involving the apex of the 2 implants. Figure 3. Case 2: Radiograph taken after placement of 2 implants on the left side. Figure 4. Case 2: Panoramic view showing radiolucent lesions surrounding the apex of the implants on the left side. Figure 5. Case 2: Radiographic image 2 months after implant removal, showing ongoing healing and resolution of the lesions.
