Osteotomy is generally performed to move the chin forward or downward in genioplasty. Alloplastic augmentation implants have been established in orthognathic surgery. The materials for chin augmentation are various, but in clinical practice, the most widely use ones include a solid flexible silicone elastic polymer. However, alloplastic implantation can be associated with several complications, including infection, bone resorption, and secondary soft tissue deformities. In this case, severe bone resorption in the chin augmentation region was found with pain in the mandibular front tooth along with apical periodontitis in the right mandibular second premolar. We suggested that the bone resorption in the present case may have been caused by apical periodontitis which infected of the chin alloplastic implants and incidentally found in a patient with a toothache. We treated with an iliac bone graft and titanium mesh. There was no evidence of recurrence of the lesion after two years of follow-up.
