Aim: The study aims to assess the impact of patient-related factors on the survival and success of
orthodontic micro-implants.
Materials and methods: A total of 50 patients (27 females, 23 males; mean age, 32.2 ± 3.9 years)
received 110 orthodontic micro-implants, which were self-tapping and tapered. The implants were
placed in the buccal alveolar bone between the premolars and molars using a self-drilling
technique under local anesthesia. Data analysis was done using SSPS software.
Results: The study cohort consisted of 50 patients, including 23 males and 27 females. The mean
age was 29.3 ± 5.54 years for males and 32.2 ± 4.67 years for females, with an overall average of
30.87 ± 1.2 years. A total of 110 orthodontic micro-implants were analyzed, with 53 placed in
male patients and 57 in female patients. Micro-implants that underwent immediate loading
demonstrated a higher failure rate, while those classified as Type III in Kuroda’s classification had
the greatest risk of failure. However, cortical bone thickness and bone density did not significantly
differ between successful and failed micro-implants.
