It was decided to place four zygomatic implants to improve stability and function, while simultaneously removing teeth in the lower jaw due to advanced periodontitis, and performing a bone graft procedure in the mandible using corticospongious bone graft from the anterior iliac crest (Fig. 2).

Examination revealed that these symptoms were caused by protruding tips of the apical part of the two zygomatic implants on the right side, which were surrounded by chronic granulomatous tissue (Fig. 3).
