Impacted upper central incisors - frequency and factors complicating the treatment protocol

Area of Science:

• Dentistry
• Orthodontics
• Pediatric Dentistry

Background:

• Central incisor eruption coincides with mixed dentition development.
• Impacted central incisors present significant esthetic concerns.

Purpose of the Study:

• To determine the frequency of impacted upper central incisors.
• To analyze factors influencing successful orthodontic treatment outcomes for impacted incisors.

Main Methods:

• Retrospective analysis of medical records from 651 patients over 3 years.
• Inclusion of 18 diagnosed and treated cases of impacted upper central incisors over 8 years.

Main Results:

• The impaction rate for upper central incisors was 1.4%.
• Males (2.8%) were more affected than females (0.7%).
• Common causes included mesiodens/supernumerary teeth (55.5%), follicular cysts (44.4%), and odontomas (22.2%).

Conclusions:

• Early detection of impacted teeth during dentition development is essential.
• Dental practitioners should actively monitor tooth formation.
