Maxilla | Type | Transposition | Description |
Mx.C.p1 | Canine - first premolar | Canine in buccal ectopia, rotated mesiobuccally, wedged between premolars | |
First premolar titled distally and rotated mesiopalatally | |||
The temporary canine is also frequently found, persisting on the arch causing a lack of temporary space on the maxillary arch. | |||
Mx.C.I2 | Canine - lateral incisor | Canine erupted mesially and buccally or completely mesially to the lateral incisor | |
Mx.C. to M1 | Canine - first molar | Canine occupying site of prematurely lost deciduous first molar | |
Mx.I2.I1 | Lateral incisor - central incisor | Complete positional interchange of lateral and central incisors | |
Mx.C. to I1 | Canine - central incisor | Canine developed in space left vacant by premature loss of central incisor | |
This transposition is characterized by the loss (absence) of the permanent central incisor on the ipsilateral side, which allows the differential diagnosis with Mx.C.I2 in which the central incisor is present. | |||
Mandible | Mn.I2.C | Canine - lateral incisor | Lateral incisor developing with severe distal tilt and rotation, crupting in site normally occupied by first premolar and canine |
