Study Notes
Epidemiology
- Maxillary impacted canines (MICs) occur in approximately 1-2% of the general population
- Females are more affected than males, with a ratio of 2:1
- Most MICs occur in the upper arch, with a ratio of 10:1 compared to the lower arch
Etiology
- Genetic predisposition
- Overcrowding and arch length discrepancy
- Abnormal tooth development and eruption
- Prolonged retention of primary canines
- Impaired resorption of primary roots
- Trauma and habits
Clinical Features
- Palpable bulge in the buccal sulcus
- Asymmetry of the maxillary arch
- Delayed or absent eruption of the impacted canine
- Associated symptoms: pain, swelling, and infection
Diagnostic Aids
- Clinical examination
- Radiographic examination:
- Panoramic radiograph (OPT)
- Periapical radiograph
- Cone Beam Computed Tomography (CBCT)
- Study models and impressions
Orthodontic Management
- Interceptive treatment:
- Early extraction of primary canines
- Creation of space in the arch
- Exposure and bonding:
- Surgical exposure of the impacted tooth
- Bonding of a gold chain or orthodontic bracket
- Orthodontic traction:
- Use of elastics or nickel-titanium springs
- Controlled orthodontic movement
- Post-treatment retention:
- Fixed or removable retainers
- Long-term monitoring and recall appointments
Complications and Challenges
- Root resorption of adjacent teeth
- Deviation from the predicted path of eruption
- Ankylosis or infraocclusion
- Root fracture or damage during surgical exposure
- Inadequate orthodontic movement or relapse
Epidemiology of Maxillary Impacted Canines
- Maxillary impacted canines (MICs) occur in approximately 1-2% of the general population.
- Females are more affected than males, with a ratio of 2:1.
- Most MICs occur in the upper arch, with a ratio of 10:1 compared to the lower arch.
Etiology of Maxillary Impacted Canines
- Genetic predisposition is a contributing factor.
- Overcrowding and arch length discrepancy can lead to MICs.
- Abnormal tooth development and eruption can cause MICs.
- Prolonged retention of primary canines can contribute to MICs.
- Impaired resorption of primary roots can lead to MICs.
- Trauma and habits can also contribute to MICs.
Clinical Features of Maxillary Impacted Canines
- A palpable bulge in the buccal sulcus is a common feature.
- Asymmetry of the maxillary arch can occur.
- Delayed or absent eruption of the impacted canine is a key feature.
- Associated symptoms include pain, swelling, and infection.
Diagnostic Aids for Maxillary Impacted Canines
- Clinical examination is essential for diagnosis.
- Radiographic examination is necessary, including:
- Panoramic radiograph (OPT)
- Periapical radiograph
- Cone Beam Computed Tomography (CBCT)
- Study models and impressions are also useful for diagnosis.

Complications and Challenges of Maxillary Impacted Canines
- Root resorption of adjacent teeth can occur.
- Deviation from the predicted path of eruption can happen.
- Ankylosis or infraocclusion can be a complication.
- Root fracture or damage during surgical exposure can occur.
- Inadequate orthodontic movement or relapse can happen.
