Current Updates of Orthodontics: New Techniques, Materials and Trends

Dear Colleagues,

This Special Issue of the journal is dedicated to the problems associated with maxilla-facial deficiency syndrome, both at the level of diagnosis and of treatment. Despite unequivocal evidence published by two research centers in Aarhus and Ann Arbor as early as 1986, confirming that the main source of Class III defects is the maxilla, this fact is still not emphasized clearly enough. Since the source of the defect was most often seen in the mandible in Class III patients in the last century, it makes sense to call the 21st century the age of the maxilla. Such a direction is also confirmed by publications and presentations of recent years. One important example is the increasing use of skeletally anchored jaw expansion appliances used in adolescents, young adults, and adult patients. This topic is the starting point for many discussions, such as the type of anchorage, the type of activation screws, jaw expansion protocols, adjunctive procedures, the age limit, and the influence of gender on the procedure of performing a maxilla expansion. Therefore, this Special Issue provides a venue to bring important conference backstage discussions to the pages of the publication, to which I strongly encourage all clinicians and authors of research in this area to submit their relevant work.
