Summary
Predicting the difficulty of forced eruption for impacted maxillary canines involves considering patient age, tooth dilacerations, angulation, overlap, and vertical distance. These factors, based on orthodontist opinions, are key for successful canine eruption.
Area of Science:
- Orthodontics
- Dental Imaging
Background:
- Impacted maxillary canines present a common orthodontic challenge.
- Assessing the difficulty of forced eruption is crucial for treatment planning.
Purpose of the Study:
- To evaluate factors influencing the difficulty of forced eruption for impacted maxillary canines.
- To correlate Cone-Beam Computed Tomography (CBCT) data with orthodontist assessments of eruption difficulty.
Main Methods:
- A literature review identified ten key factors for assessing eruption difficulty.
- CBCT scans of 50 impacted maxillary canines from 36 patients were analyzed using Dolphin 3D software.
- Ten experienced orthodontists provided subjective difficulty ratings (SDD) for each canine's forced eruption.
Main Results:
- The mean subjective degree of difficulty (SDD) was 6.45 ± 1.22.
- Linear regression revealed significant correlations between SDD and patient age, dilacerations, vertical height, angulation, and horizontal overlap (P < 0.05).
Conclusions:
- Patient age, dilacerations, angulation, overlap, and vertical distance from the occlusal plane are the most significant predictors of forced eruption difficulty for impacted maxillary canines.
- These variables, combined with orthodontist expertise, aid in predicting treatment complexity.
