Transmigration of impacted mandibular cuspids
International Journal of Oral Surgery
|December 1, 1985
Summary
Transmigration of impacted mandibular cuspids, where over half the tooth crosses the midline, is rare. This study presents 13 cases, totaling 16 teeth, with varied impaction positions observed on radiographs.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Orthodontics
Background:
- Impacted mandibular cuspids are uncommon dental anomalies.
- Transmigration is defined as a specific type of impaction where the tooth's long axis crosses the midline.
Purpose of the Study:
- To report on the occurrence and radiographic presentation of transmigrated impacted mandibular cuspids.
- To analyze the positional variations of these rare dental findings.
Main Methods:
- Review of 13 clinical cases exhibiting transmigrated impacted mandibular cuspids.
- Radiographic analysis to determine the position and extent of transmigration for each affected tooth.
Main Results:
- Thirteen cases of impacted mandibular cuspids were identified, involving a total of 16 teeth.
- Three cases presented with bilateral (paired) transmigration.
- Observed radiographic positions ranged from vertical impaction to complete midline crossing, extending to the contralateral first molar region.
Conclusions:
- Transmigration of impacted mandibular cuspids is a rare but documented phenomenon.
- The radiographic presentation of transmigration is highly variable, requiring careful diagnostic evaluation.
