This guided seminar course for students in Year 2 of the MSc Orthodontics program provides the students the ability to clearly identify clinical situations where early intervention will be most beneficial to patients, together with the limitations of such interventions. The objective is for students to be able to identify clinical situations where early and interceptive treatment is indicated, develop knowledge and familiarity with the treatment modalities available in interceptive orthodontics, become aware of the cost benefit analysis and the relation between early and definitive treatments and finally, to be able to apply appropriate early treatment optimally or to reassure and enlighten patients and parents when later treatment is more beneficial.
