To get out of trouble in managing complex cases, orthodontists should understand biomechanics concepts and solutions, as well tooth movement biology. The correct application of the force system impacts the biological tissue responses inducing different responses in a favorable or unfavorable manner. The biomechanical domain prevents round tripping, unnecessary increase in treatment time, and damage to the dentoalveolar tissues. Indubitably, minimizing or preventing unnecessary tooth movement helps to decrease treatment time, which has been associated with root resorption and surrounding tissue damage. In the absence of the correct force system application (forces and moments), </span></span>orthodontic treatment<span> outcomes become unpredictable. Therefore, the key to success is the correct application of the biomechanics, and clinicians must have biomechanical knowledge and skill in reserve, which will be required when unfortunate surprises strike.
