Comparison of the degree of deflection between titanium and stainless steel mini implants placed on the buccal shelf. In vitro study

Dental anchorage is a key component in orthodontic treatment, helping to control unwanted tooth movement, including reciprocal, reinforced, stationary, cortical and skeletal anchorage; mini-implants are used as a solution to improve control of tooth movement. Mini-implants, introduced in 1997, offer a stable and mechanical option to reduce dependence on patient cooperation. This work compares stainless steel and titanium mini-implants placed in the buccal shelf of pig jaws to evaluate their deflection under controlled loads. A sample of 20 pig jaws and 40 mini-implants (20 stainless steel and 20 titanium) were used, analyzing the deflection of the implants by precise measurement and the application of a 200 gram load. The results of this study provide information on the viability and effectiveness of mini-implants, specifically regarding their resistance to deflection, which contributes to improving orthodontic practice in terms of accuracy and long-term stability.
