When a tooth is twisted along its long axis, what is this condition called?

When a tooth experiences twisting along its long axis, this condition is referred to as torsion. Torsion specifically describes the rotational movement of a tooth, which can have significant implications for dental alignment and occlusion. It involves the alteration of the tooth's position and orientation, affecting how the tooth interacts with neighboring teeth and impacting overall bite functionality.

The other terms relate to specific angulations or positional changes of teeth in relation to their orientation but do not specifically denote the twisting motion characteristic of torsion. For instance, mesio version, disto version, and lingual version describe positional shifts toward the mesial, distal, or lingual surfaces of the dental arch, respectively. These terms focus on the direction in which the tooth is tilted rather than encompassing the full rotational movement involved in torsion. Understanding these distinctions is essential in dental practice, as it helps in diagnosing and addressing alignment issues effectively.
