Mini-implants in T-zone: which are the risks?

Cristiane B. André

Introduction: The skeletal anchorage technique in orthodontics is frequently used. For a long time, it was believed that the palate is a safe region for the mini-implants insertion. Although there are areas that usually have adequate bone volume, it is fundamental to evaluate each patient individually and three-dimensionally before any drilling in this region (tomography and intraoral scanning). Objective: Thus, this paper aims to present the adversities found in the T-zone anterior region, which have the potential to cause injury, compromise biomechanics, or even cause failure of the technique. Conclusion: These adversities can make therapy difficult for professionals who do not use 3D images for their diagnoses and treatment plans, because they are not visible clinically or even on radiographs. A technique that provides more security and precision during this procedure will be presented.
