Lecture Description
Introduction : Flaring of anterior teeth in orthodontic treatment could induce inappropriate circumstances in terms of esthetics and functions. So, even in non-extraction orthodontic treatment, keeping the position of anterior teeth is very important and retracting anterior teeth might be required for better results. In order to achieve satisfied outcomes, we need to make spaces to align teeth backward or to retract teeth under non-extraction condition.
Discussion : Five non-extraction cases were successfully treated using combination of 4 methods (full arch retraction; FAR, arch expansion, interproximal reduction; IPR and torque bends) without flaring anterior teeth regardless of gender, age and malocclusion type. Appropriate combination of 4 methods for each case was determined and used. It is important to take a strategic approach for each dental arch by considering the patient's soft tissue, the type of malocclusion, and the inclination of upper and lower incisors in combination.
Conclusion : Our results demonstrate that combination of 4 methods is an effective strategy to align teeth backward or to retract anterior teeth presenting good results in non-extraction orthodontic treatment. Orthodontist should keep in mind that an appropriate combination of 4 methods would be suitable for each case. And we suggest that one should consider availability of these methods from the first step in orthodontic treatment in making diagnosis, to determine extraction or nonextraction.
