Resistance to immediate orthodontic loading of surface-treated mini-implants.
OBJECTIVE To test the hypothesis that there is no difference in the stability and resistance to orthodontic forces of immediately loaded sandblasted and acid-etched (SAE) mini-implants and those of machined-surface implants of the same size and shape. MATERIALS AND METHODS Two types of mini-implants were used in the tibiae of 44 rabbits; some had an SAE surface and some had machined surfaces....
متن کاملTitanium alloy mini-implants for orthodontic anchorage: immediate loading and metal ion release.
Removable osseointegrated titanium mini-implants were successfully used as anchorage devices in orthodontics. The early load is necessary to simplify the mini-implant methodology, but can lead to failure during osseointegration. The Ti-6Al-4V alloy was used instead of commercially pure Ti due to its superior strength. However, the corrosion resistance is low, allowing for metal ion release. The...

متن کاملEvaluation of cytotoxicity and corrosion resistance of orthodontic mini-implants
Objective: To evaluate and compare in vitro cytotoxicity and corrosion resistance of mini-implants from three different commercial brands used for orthodontic anchorage. Methods: Six mini-implants (Conexão(tm), Neodent(tm) and SIN(tm)) were separately immersed in artificial saliva (pH 6.76) for 30 and 60 days. The cytotoxicity of the corrosion extracts was assessed in L929 cell cultures usin...
متن کاملEvaluation of primary stability of inclined orthodontic mini-implants.
The aim of this study was to investigate the initial stability of mini-implants when placed slanting or perpendicular to the bone surface, and to examine the effects of differences in tractional direction. Titanium mini-implants were inserted into rabbit nasal bones, slanting (60 degrees , 120 degrees ) or perpendicular (90 degrees ) to the bone surface. These implants were then loaded with a f...
