Three-dimensional skeletal and pharyngeal airway changes following therapy with functional appliances in growing skeletal Class  II malocclusion patients
DiscussionThe TWB functional appliance induced significant skeletal and pharyngeal airway changes. These changes were more obvious relative to the slight changes induced by FFRD or by natural growth. (Source: Journal of Orofacial Orthopedics/Fortschritte der Kieferorthopadie)

Effect of rapid maxillary expansion on the morphology of spheno-occipital synchondrosis in rats
ConclusionsEarly SOS widening could be identified in the lowest part before median palatal suture opening. Similarly, narrowing of the SOS at its top was observed before the most significant median palatal suture expansion. Thus it can be hypothesized that changes within the SOS complex result from the transmission of the orthopaedic forces rather than from a  displacement of the maxillary halves.

Experimental friction and deflection forces of orthodontic leveling archwires in three-bracket model experiments
ConclusionsOrthodontic tooth movement is quasi-static. This concerns the initial hyalinization phase in particular. Thus, especially static testing of archwires provides valid reference data for the peak forces exerted directly after clinical insertion of a  leveling wire. In dynamic wire testing, significant underestimation of actual forces exerted on individual teeth may occur due to experimental friction, which might considerably differ from that occurring during clinical therapy. This aspect has to be taken into account in the interpretation of pu blished stiffness values for orthodontic wires, and in the selection of...

Is there a relationship between maxillary canine impaction and ocular asymmetry
ConclusionsBoth hypotheses were accepted. A  relationship between the impacted maxillary canine and ocular asymmetry could not be demonstrated. (Source: Journal of Orofacial Orthopedics/Fortschritte der Kieferorthopadie)
