In which direction would you extract a deciduous upper molar?

The extraction of a deciduous upper molar is typically performed buccally. This direction aligns with the natural angulation and positioning of the roots of the maxillary molars, which are usually broader and positioned towards the buccal side. Extracting buccally minimizes the risk of damaging surrounding soft tissues and allows for better control during the removal process.

Choosing the buccal direction also takes advantage of the anatomical structure of the tooth; the roots of upper molars spread out more towards the buccal aspect. This makes it easier to apply the necessary force for extraction while avoiding the risk of complications that may arise from other extraction approaches. The other options, such as lingually or apically, would not be ideal for this kind of tooth due to the risk of damaging adjacent teeth or anatomical structures, and rotational movements could lead to insufficient leverage and potential complications during the extraction.
