Constrain tooth position

You can constrain a tooth at its original position by right clicking the tooth. This function is usefull when you want to keep molar occlusion and align anterior teeth only.

When molars are constraint unilaterally, the midline will be adjusted to keep antposterior position of the incisor. When molars are constraint bilaterally, the incisor position and the midline will be adjusted. Also, when bilateral upper molars are constrained, overjet and overbite will be adjusted to avoid interference of incisors.

If you want to change lower incisor position or overjet while constraining the molarposition, you can apply IPR to adjust them.
