Modified Grassline Technique for Orthodontic Space Closure
Lohmiller, Rose Marie
Use of traditional orthodontic measures in the periodontally compromised dentition can be problematic. This article describes a variation of the Grassline technique, in which the author uses adhesive bonding to harmoniously re-align malpositioned teeth. In this simple, easy-to-learn technique, a cotton thread is used to achieve orthodontic tooth movement. Initial contact with the saliva causes shrinkage of the thread, exercising a minor force that moves the teeth while allowing enough time for the tissues to regenerate. With this moderate, intermittent force, successful treatment is achieved with minimal risk. Moreover, this orthodontic technique has been associated with an increase in bone volume. This article presents this new technique and details methods for maintaining treatment success. The technique also is compared with an approach described in the literature. Two case reports are presented; the technique is employed in the first to close a diastema in a periodontally compromised dentition and in the second to correct the migration of maxillary and mandibular incisors. Photographs and radiographs show the esthetic improvement achieved in both cases using this technique.
