Exclusion criteria
Exclusion criteria: 1.

There is evidence of past or current osteomyelitis or osteonecrosis of the jaw; 5. Those who have received treatment with bisphosphonates, fluoride, or strontium agents within 6 months; 6. Those who have received teriparatide and denosumab treatment within 6 months; 7.
