Figure 1. Clinical photograph of the hyperplastic lesion on the lingual peri-implant mucosa around the healing caps. Figure 2. The lesion remained stable in size 1 week after the removal of the healing caps. Figure 3. Panoramic radiograph does not reveal bone erosion or ossifications in the lesion. Figure 4.
