Eruption rates of human upper third molars.
Human maxillary third molars have been observed to have maximum rates of eruption of approximately 1 mm/2 mo. Rates of less than 1 mm/6 mo have also been recorded. Maximum rates of eruption were associated with spacing of the dentition. Passive eruption in the form of gingival recession is an important factor resulting in the exposure of the clinical crown.
