Classification of Wisdom Teeth Growing Status
Wisdom teeth erupt during the end stage of human growth and development. Before the eruption, wisdom teeth complete the formation process of the crown, neck, and root in the jaw, as well as the “drifting” and “uprighting” process. Because of the degeneration of the human jaw, the growing space for wisdom teeth is only the remaining space at the latest stage of jaw development. Therefore, the wisdom teeth often fail to complete the “drifting” and “uprighting” process and are impacted in a certain status in the jaws. In order to accurately reflect and describe the growing status, the concepts of vertical, horizontal, tilting, malposition, embedding, and direction of wisdom teeth are put forward in three-dimensional structure.
