— To evaluate the results of early interceptive grinding and also the possibility of selfcorrection of unilateral cross‐bite, 76 4‐yr‐old children with this malocclusion were divided into one treated and one untreated group. In the treatment group 50% of the children exhibited a normal transverse occlusion evaluated in the mixed dentition, at the age of 9. In the untreated group only 17% showed a spontaneous correction of the cross‐bite. Among the studied dental variables the “max./mand. arch width difference” especially in the canine region was found to be a valuable predictor indicating whether cross‐bite can be successfully treated in preschoolchildren by selective grinding. The results of this study support early treatment of unilateral cross‐bite and gives the criteria whereby successful treatment by selective grinding may be expected.
