The purpose of this work is to study the form's and transversal dimensions changes of dental arches during the orthodontical treatment within the first premolars extractions. Our sample is composed of thirty treated casts in Edgewise technique in the orthodontic service in Center of Consultation and Dental Treatment (C.C.D.T.) of Rabat. In order to realise this study, we have used in the treatment's beginning and final of each case mandibular moulding. On our results base, it brings out that the intercanine distance increases whereas the intermolar distance decrease during the orthodontical treatment, and that the only found dismorphism is linked to the treatment's options (extraction- non extraction) only for intermolar distance.
