Innovative virtual set-up to evaluate arch form effects

Introduction. An innovative virtual set-up is proposed to evaluate individual arch form effects on dental crown and root position during alignment. Materials and methods. Angle Class I and skeletal Class I (ANB = 2°) of the patient are taken. A superimposition of the scanned model and the cone beam (CBCT) image is carried out to obtain dental crown and root anatomy. Virtual alignment is obtained following individual arch form and full expression of Roth prescription bracket. Final crown and root position is visualized in relation to the original dental arch. Conclusion. In the era of CBCT, a great deal of attention has to be given not only to final crown position, but also to final root position as regards cortical limits. It has become important to individualize not only the arch form, but also the bracket, to obtain better results in stability and dental health.
