Inclusion criteria
Inclusion criteria: 1. Postmenopausal women aged 50 to 85 years who have the ability of independent activity. Postmenopause is defined as menopause time >=3 years, i.e. spontaneous amenorrhea >=3 years or bilateral oophorectomy >=3 years. For the patients with hysterectomy but ovarian preservation, the menopause should be confirmed by FSH level >=40 U/L; 2. Based on the measurement results of bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA), the BMD t-value of lumbar spine (L1-L4) or total hip is less than - 2.5, and the BMD t-value of any part should be more than - 4.0/l; 3. Patients with at least one of the following risk factors: (1) Previous history of brittle fracture, such as hip, distal radius or vertebral fracture; (2) Father or mother hip fracture history; (3) Low body mass index (BMI =65 years old); (5) Smoking at present; 4. Patients who voluntarily participated in the trial and signed the informed consent.

Patients with other diseases such as rheumatoid arthritis, gout, multiple myeloma, etc. 3. Patients with 2 or more lumbar fractures; 4. Patients with malignant tumors: malignant tumors in recent 5 years (except for completely excised in situ skin basal cell or squamous cell carcinoma, cervical cancer or breast duct cancer); 5. In patients with severe kidney disease, the clearance rate of creatinine (CR) was less than 30 ml/min; 6. Patients with the following liver or biliary diseases: (1) Cirrhosis; (2) Abnormal bile duct (except for asymptomatic gallstones); (3) Hepatitis C virus (HCV) antibody was positive; (4) If HBsAg is positive and the titer of HBV DNA in the peripheral blood >=1x10^3 copies/ml, and the titer of HBV DNA in the peripheral blood is =1.5 ULN; aspartate transaminase (AST) >=2.0 ULN; alanine transaminase (ALT) >=2.0 ULN; 7. Patients with the following oral and dental diseases: (1) Previous or current cases of osteomyelitis or osteonecrosis of the mandible; (2) Acute dental or mandibular disease requiring oral surgery; (3) During the trial, invasive dentistry was planned; (4) Dental or oral surgery is not cured; 8. Influence of DXA bone mineral density measurement: (1) There are less than two lumbar vertebrae that can be measured by DXA; (2) Height, weight or waistline may hinder the accurate measurement of DXA; 9. Those who have received anti osteoporosis treatment or drugs affecting bone metabolism: (1) In the past 5 years, they received RANKL inhibitor, fluoride or strontium salt treatment or intravenous bisphosphonate; (2) Patients taking bisphosphonates orally, but with the following conditions, can be included in the group: Cumulative use > 3 months but =6 months; Cumulative use 5 Mg/day prednisone > 10 days); syst
