[Clinical stability of immediate load of domestic micro-titanium screws for anchorage in orthodontics].
OBJECTIVE
To investigate the immediate load stability of domestic micro-titanium screws for anchorage in orthodontics.


METHODS
Adult orthodontic patients needing the greatest anchorage were included in the study. Domestic micro-titanium screws were used to be orthodontic anchorage, immediate implantation and loading were conducted.


RESULTS
A total of 52 implants of domestic micro-titanium anchorage in 20 patients were used. Forty-seven implants were successful in 20 patients,5 failed. The total loading time was 3-8 months.


CONCLUSIONS
Domestic micro-titanium implant screws for anchorage can meet the needs of clinical orthodontics. However, immediate loading results in 10.4% failure rate, especially for the implant with a diameter of 1.2mmx7mm.
