Abstract		Background: A lingual position of maxillary incisors in relation to the opposing mandibular teeth is called anterior crossbite. Dento-alveolar crossbite is to be distinguished from skeletal one which requires complex orthodontic treatment, sometimes combined with orthognatic surgery. The aim of this study was to evaluate an interceptive method of orthodontic treatment for dento-alveolar crossbite of a single anterior tooth in the mixed dentition with the use of an acrylic inclined plane. Subjects and methods: An acrylic inclined plane was cemented to a lower incisor in fifteen patients aged six to eight years, presenting with single-tooth anterior crossbite in the mixed dentition. The plane, inclined at an angle of 45°-60° to the longitudinal axis of the tooth, was made from self-curing acrylic by a direct method. On follow-up visits, the position of the affected incisor and treatment-related signs and symptoms were assessed. Results: In all fifteen patients normal overjet and overbite was achieved after a short treatment period. In four patients the inclined plane was removed after one week, and in eleven patients after two weeks. No adverse effects or major complaints related to the treatment were noted. Conclusion: The use of an acrylic inclined plane proved to be an effective treatment method for single-tooth anterior crossbite in the mixed dentition.
Summary		Izhodišče: Pri križnem grizu sekalcev so zgornji sekalci lingvalno za spodnjimi. Ločiti moramo dentoalveolni križni griz od skeletnega, ki zahteva kompleksno ortodontsko in včasih tudi kirurško zdravljenje. Želeli smo oceniti uspeh interceptivnega ortodontskega zdravljenja dentoalveolnega križnega griza s poševno ravnino iz akrilata, kadar je v obdobju menjalnega zobovja v križnem grizu eden od zgornjih sekalcev. Preiskovanci in metode: Petnajstim preiskovancem, starim 6 do 8 let, ki so imeli v križnem grizu posamezen zgornji sekalec, smo na spodnje sekalce cementirali poševno ravnino s široko bazo, izdelano po direktni metodi iz hladno polimerizirajočega akrilata, z naklonom 45° do 60° na vzdolžno os spodnjega sekalca. Pri kontrolnih pregledih smo ocenjevali položaj prizadetega sekalca ter simptome in znake v zvezi z zdravljenjem. Izsledki: Križni griz smo pri vseh petnajstih preiskovancih odpravili v kratkem časovnem obdobju. Štirim preiskovancem smo poševno ravnino odstranili po enem tednu, enajstim pa po dveh tednih. Neželenih učinkov ali večjega nelagodja v zvezi z zdravfenjem nismo ugotovili. Zaključek: Uporaba poševne ravnine iz akrilata se je izkazala kot uspešna metoda zdravljenja dentoalveolnega križnega griza, kadar je v obdobju menjalnega zobovja v križnem grizu posamezen zgornji sekalec.
