Orthodontic goniometry: a control technique after P. Planas transversal expansion method: neuro-occlusal...

Orthodontic goniometry applied to expansion cases treated by P. Planas method (neuro-occlusal rehabilitation) demonstrates considerable bimaxillary transverse expansion (crown and apices). Maximal expansion of 10 mm was noted for mandibular apices with a mean of 5.8 mm. Maximal expansion of 11.5 mm was noted for maxillary apices with a mean of 8.11 mm. Results were stable, some being controlled more than eight years out of retention.
