What orthodontic intervention is primarily focused on when transitioning from primary to mixed dentition?

The primary focus of orthodontic intervention during the transition from primary to mixed dentition is the guidance of eruption. This period is critical as it involves the transition of the primary dentition, which consists of baby teeth, to the mixed dentition, where both primary and permanent teeth are present.

During this phase, there is a significant change in the dental arch as permanent teeth begin to erupt. Orthodontic practitioners aim to ensure that these teeth erupt in an appropriate position and alignment, avoiding potential crowding or malocclusion. By guiding eruption, orthodontists can influence the timing and path of eruption for the permanent teeth, which can help establish a functional and aesthetic occlusion early on.

This intervention may involve monitoring the spatial development of the arches, making decisions about whether to retain certain primary teeth until the appropriate time for eruption, and possibly using space maintainers or other appliances to support proper alignment as new teeth emerge. By focusing on this guidance, orthodontists can set the stage for optimal dental alignment and function as mixed dentition progresses into the permanent dentition stage.

While extraction of deciduous teeth can occur, it is not the primary focus of intervention at this stage unless there are specific issues requiring it. Similarly, the application of fixed
