The surgical division of the gingival fibres around a rotated tooth has been recommended as a method of reducing the amount of relapse that occurs subsequent to orthodontic alignment.
In the present study, the amount of relapse is measured in a group of patients in which the gingival fibres had been sectioned following alignment of rotated teeth and compared with a group in which there had been no surgical intervention after tooth alignment.
A reduction in the amount of rotational relapse is demonstrated and an optimum period of retention is suggested.
