Computer-guided surgery using the piezocision technique.

A variety of surgical procedures have been developed to accelerate orthodontic treatment of adult patients seeking to enhance their smiles or masticatory function. While most of these techniques are invasive, the minimally invasive piezocision technique reduces trauma by combining microincisions and localized piezoelectric bone surgery. A method for combining piezocision with the use of computed tomography is presented here. By creating a three-dimensional model of the arch, the depth and location of the corticotomies can be precisely planned, and a surgical guide can be fabricated and used to prevent any damage to the dental roots.
