title: [Experimental bodily tooth movement through the bony floor of the nose--a pilot study].
abstract: Our experiment on animals was carried out in order to show to which degree the dog's bony nasal floor--taken as an equivalent of the recessus of the human maxillary sinus--is an obstacle to bodily tooth movement. The metric analysis showed that the movement of the upper teeth in comparison with the teeth of the lower jaw was markedly impaired by the basal cortical bone of the cavum nasi. Extended resorption of the basal bone of the nose was found histologically. The pressure side of the root surface too showed resorption lacunae which reached into the dentine deeply and were bordered by some osteoclasts.
