TYPES OF IMPACTIONS
Mesioangular impaction is the most common form (44%), and means the tooth is angled forward, towards the front of the mouth.
Vertical impaction (38%) occurs when the formed tooth does not erupt fully through the gum line.
Distoangular impaction (6%) means the tooth is angled backward, towards the rear of the mouth.
Horizontal impaction (3%) is the least common form, which occurs when the tooth is angled fully 90 degrees sideways, growing into the roots of the second molar.
