Correct answer: A — Active bisphosphonate therapy for metastatic bone disease
Active IV bisphosphonate therapy for metastatic bone disease is a relative-to-absolute contraindication for dental implant placement due to the significant risk of MRONJ. Other contraindications include active chemotherapy/immunosuppression, uncontrolled diabetes, radiation therapy to the jaw (>50 Gy), inadequate bone volume (without augmentation), active periodontal disease (untreated), and growth (paediatric patients — implants should not be placed until skeletal growth is complete). Former smoking, controlled diabetes, and treated periodontitis are manageable risk factors.
