What is the optimal time for orthodontic treatment involving growth manipulation?

  1. Early mixed dentition

  2. Late mixed dentition

  3. Permanent dentition

  4. Pre-pubertal growth spurt

The correct answer is: Late mixed dentition

In orthodontic treatment involving growth manipulation, the optimal time for treatment is during the late mixed dentition stage. This is because during this stage, the permanent teeth have started to come in, but the jawbones are still growing, allowing for more effective manipulation and correction of any orthodontic issues. A Early mixed dentition is not the optimal time for orthodontic treatment involving growth manipulation as the jawbones are still growing significantly and it may be too early to determine the extent of orthodontic issues that require treatment. C: Permanent dentition is also not the optimal time as the jawbones have stopped growing, making it more difficult to manipulate them for treatment. D: Pre-pubertal growth spurt may seem like a viable option, but it is important to note that orthodontic treatment during this time can potentially interfere with the natural growth and development of the jawbones
