Key points

  • Other than third molars, the maxillary canine teeth are the most commonly impacted teeth.

  • Surgical intervention and coordination of care with the orthodontist will lead to improved outcomes.

  • Various surgical procedures are used depending on the position of the impacted tooth.

Incidence and etiology

Studies reporting the incidence of impacted teeth vary considerably in their conclusions, likely due to regional genetic differences, the dental health of the population studied, and interpretation of what constitutes impaction.

Aside from third molars, maxillary canines are the most commonly impacted teeth.1, 2 There is a 2:1 incidence among females over males and a 2 to 3 times higher likelihood of palatal versus labial impaction.3 The incidence of maxillary impaction has been reported to be

Early diagnosis

After the age of 9 or 10 years when patients often first consult with the orthodontist, there are well-established warning signs of potential canine impaction.12Clinical signs include:

  1. Absence of the canine bulge with palatal impactions (Fig. 1)

  2. Peg-shaped or missing lateral incisors

  3. A constricted maxilla with dental crowding

  4. Female patients 2:1 higher incidence

  5. Class I occlusion in the mixed dentition

Radiographic signs include (Fig. 2)13:
  1. Lateral or central incisor overlapped by the erupting canine

  2. Enlarged follicular sac of the erupting canine

  3. Lack of

Interceptive treatment

Interceptive treatment may reduce the incidence or severity of canine impactions. Although inconclusive, some studies have shown an improved spontaneous eruption of developmentally delayed canines when the primary canine is extracted.18 It is not fully understood why this strategy expedites canine eruption, although removing an obstacle to eruption is the prevailing orthodontic rationale. However, the “Regional Acceleratory Phenomena”19, 20, 35 may be an underlying contributory factor. This

Summary

Ideal management of the impacted canine is a complex process involving a carefully orchestrated effort on the part of the orthodontist, surgeon, and others. Communication among clinicians is an essential component of successful treatment. This communication should include which type of surgical approach is to be used for the specific case. The surgeon needs to understand the various treatment options.

Evidence-based diagnosis, treatment planning, and appropriate technique can result in a highly
