Summary
Impacted maxillary central incisors show significant developmental deviations, with inverted impactions featuring more root dilaceration. Early orthodontic intervention is crucial for managing these cases.
Area of Science:
- Dentistry
- Orthodontics
- Oral and Maxillofacial Surgery
Background:
- Impacted maxillary central incisors are a common clinical concern.
- Understanding their 3D morphology is key for effective orthodontic treatment planning.
Purpose of the Study:
- To investigate the three-dimensional morphological characteristics of impacted maxillary central incisors.
- To guide early orthodontic intervention strategies for impacted maxillary central incisors.
Main Methods:
- Cone-beam CT scans of 102 patients with unilateral impacted maxillary central incisors were used.
- 3D models were created for volume and surface area measurements.
- Root development and morphological abnormalities were analyzed and compared to controls.
Main Results:
- Impacted incisors showed significantly reduced crown volume and surface area compared to controls.
- Root development was significantly delayed in impacted incisors.
- Inverted impactions had a higher prevalence of root bending (72.1%) compared to labial (15.4%) and palatal (30%) impactions.
Conclusions:
- Inverted impacted central incisors exhibit more dilacerated roots and poorer development, necessitating early orthodontic intervention.
- The findings provide valuable insights for tailoring orthodontic strategies based on impaction type.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
