Beyond Osseointegration: Dealing With Late Dental Implant Complications

Figure 1. (a) Implant crown on #30 had rotated buccally. (b) Removed implant crown and fractured abutment. (c) New modified implant crown with narrower occlusal table. Figure 2. (a) Deep probing depths around the implant on #18. (b) Excess cement evident on radiograph. (c) Removed implant crown with large amounts of excess cement underneath. Figure 3. (a) Deep probing depths with bleeding on probing around #8. (b) Residual calculus on the exposed threads after nonsurgical debridement. (c) Healthy peri-implant soft tissues 3 months after debridement.

(a). Panoramic radiograph showing multiple failing implants in the upper and lower jaw. (b) Clinical view of the patient with multiple abscesses around the implants. (c) Implants on the lower jaw remained osseointegrated and were cleaned up nonsurgically. (d) Explanted upper implants supporting a noncleansable prosthesis.

Figure 5. (a) Anterior implant with exposed threads. (b) Periapical radiograph showing the aggressive implant thread design, which is now clinically visible through the soft tissues. (c) Clinical situation after explantation. Figure 6. (a) Fractured implant on the #19. (b) Periapical radiograph showing implant fracture and significant bone loss around the #19 and #20. (c) New implants placed 6 months after guided bone regeneration.
