fixed versus removable appliance for palatal expansion; a 3d analysis using the finite element method.

several appliances have been used for palatal expansion for treatment of posterior cross bite. the purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (fem) analysis.two 3d fem models were designed ...

The EFL Pre-Service Teacher Training in Iran: Is it Adequate or not?

Teacher training programs should provide evidence that they are preparing teacher trainees for their teaching career. However, the literature contains few evaluation reports of the layout of the pre-service EFL teacher training program in Iranian EFL context, a gap which this study tries to fill. The participants of the study were high school EFL teachers (n = 346), teacher trainees (n = 97) an...
