An evaluation of the effectiveness between stainless steel mini-implants and titanium alloy mini-implants: a randomised clinical trial / Zubaidah Mohammad Zubir

The application of temporary anchorage devices such as mini-implants or mini-screws and mini-plates are gradually accepted in orthodontics as methods to reinforce anchorage. Although titanium alloy (TiA) mini-implants are well-known for their biocompatible behaviour in comparison to stainless steel (SS) mini-implants, only several studies are found to be investigating the clinical aspects of SS mini-implants. This research aims; 1) to measure and compare the rate of anchorage loss between SS and TiA mini-implants, 2) to measure and compare the rate of upper labial retraction between SS and TiA mini-implants, 3) to compare the discomfort experience between SS and TiA mini-implants. This research is comprised of twenty-seven patients (12 males: 15 females; mean age 23.7 + 5.25 years) obtained from Universiti Teknologi MARA postgraduate clinic.
