For a primary intrusive luxation, which scenario requires extraction?

When a primary tooth is intruded and the developing permanent tooth germ is involved, removing the primary tooth is the best course. The tooth germ is at risk of damage if the primary tooth is left—repositioning such a tooth or relying on spontaneous eruption could disrupt the eruption path, harm the permanent successor, or lead to malformation or resorption of the developing tooth. Extraction eliminates this risk and allows the permanent tooth to erupt normally. Spontaneous eruption or repositioning can be appropriate only when the intrusion does not involve the tooth germ; otherwise, these options carry a higher risk to the developing dentition.
