Explanation:
Detailed explanation-1: -Definition and Features Line angles are defined as the lines that mark the transition from the buccal and lingual surface to the proximal one [2]. Each tooth exhibits four lines angles: mesiofacial, distofacial, mesiopalatal, and distopalatal.
Detailed explanation-2: -There are three transitional line angles in maxillary anterior teeth that represent the area of transition between the two proximal surfaces and incisal surface with the facial surface. Altering the distance between the two proximal line angles gives the illusion of making the tooth appear wider or narrower.
