title: [Transverse expansion with plate appliances--their intermolar stability and significance for gingival recession].
abstract: This study was undertaken to investigate if transversal expansion with removable plates is a predisposing factor in the occurrence for buccal recessions in the molar region. In order to clarify a possible causal relationship, it is important to know to what extent the therapeutic expansion remains stable, 58 former patients, ages ten to 15, were studied following transversal expansion and non-extraction therapy with removable appliances. Intermolar expansion and stability, clinical crown length, and the incidence of buccal recessions on the incisors and six-year molars were evaluated. The study revealed that with relatively good intermolar stability (relapse between 13% and 14%), when compared with an untreated control group and with the data contained in the literature, recessions do not increasingly occur.
