Abstract     Tooth surface loss is frequently accompanied by dento-alveolar compensation, which ensures that in the majority of patients occlusal contacts between worn teeth and their antagonists are maintained. The apparent lack of interocclusal space presents a dilemma for the restorative dentist. Interocclusal space can be created by further occlusal reduction of the worn teeth, by orthodontic therapy or by using a Dahl-type appliance. In the year 1975, Dahl and co-workers described the use of a removable metal bite platform to create interocclusal space in patients with advanced tooth surface loss in the anterior region. Such an appliance covers the affected teeth and increases the occlusal vertical dimension. On insertion, the posterior teeth are discluded. The patient wears the appliance continually until the posterior teeth eventually achieve occlusal contact. On removal of the appliance, sufficient anterior interocclusal space is present to allow the restoration of worn teeth without further occlusal tooth reduction. This paper reviews the literature related to the effect, duration and possible side-effects of treatment with the Dahl appliance. Some modern applications of the technique are briefly presented.
Summary     Obrabo zob pogosto spremlja izraščanje zob, zaradi katerega obrabljeni zobje ostajajo v stiku s svojimi antagonisti. Posledica tega je, da kljub izgubi trdih zobnih tkiv med obrabljenimi zobmi in njihovimi antagonisti nimamo na voljo prostora (interokluzijskega prostora), ki ga potrebujemo za protetično oskrbo obrabljenih zob. Prostor lahko pridobimo z brušenjem obrabljenih zobnih površin, z ortodontsko terapijo ali z uporabo Dahlove opornice. Dahl in sodelavci so leta 1975 predstavili uporabo snemne kovinske opornice za povečanje interokluzijskega prostora med obrabijenimi zobmi interkaninega predela in njihovimi antagonists. Opornica, ki jo pacient neprestano nosi, pokriva obrabljene zobe in povzroči razmik med zobmi transkaninega predela. Ko se po določenem času ponovno vzpostavijo okluzijski stiki med zobmi transkaninega predela, opornico odstranimo. Povečan interokluzijski prostor med zobmi interkaninega predela omogoči protetično oskrbo obrabijenih zob brez brušenja obrabljenih zobnih površin. V prispevku so opisani rezultati kliničnih raziskav o učinku Dahlove opornice, trajanju terapije in mogočih neželenih učinkih. Omenjene so tudi možnosti uporabe nekaterih sodobnejših izvedb Dahlove metode.
