Wisdom teeth with proximal-medial obstruction have neighboring teeth resistance, crown resistance, root resistance, and are relatively more difficult to extract than teeth in normal position.
1. Neighboring teeth resistance: The crown of the mesiodistant wisdom tooth is tilted towards the middle of the proximal region, and the front teeth have resistance, which should be removed when extracting the tooth.
2. Crown resistance: The wisdom teeth with proximal-medial obstruction also have different degrees of obstruction from the alveolar bone and soft tissues of the crown, which need to be removed when extracting the teeth.
3. Root resistance: Wisdom teeth usually erupt later and the root varies greatly, so the root resistance may be greater than normal teeth.
It is relatively difficult to remove wisdom teeth in the middle of the proximal area, and it is best to choose to go to a regular hospital to take a surface tomography to analyze the resistance of the wisdom teeth, and it is safer to have the teeth extracted by a professional physician.
