Closure of a 2mm midline diastema by orthodontics is best accomplished at which stage?

Closing a gap between teeth, also known as a diastema, can be achieved through orthodontic treatment. However, in order to achieve the best results, it is important to time the treatment correctly. Option A may not be the best choice as lateral incisors usually erupt before the development of a diastema. Option C may also not be ideal as it may delay the natural closure of the gap by the eruption of premolars. Option D may not be the most efficient as it is after the peak of the teenage growth spurt and the jawbones have already reached their maximum size. Option B, after the complete eruption of maxillary canines, is the best stage for closure of a 2mm midline diastema as this is when most of the permanent teeth have grown in and the jawbones have reached their full size, allowing for more precise and stable results.
