Comparative evaluation of various orthodontic maxillary expanders in children nith mixed dentition. Material and methods: Under observation were 26 children aged 12 to 14 years with a changeable bite with a narrowing of the upper jaw and speech impairment. In 13 (50%) children of the 1st group, treatment was carried out using a dental expander for the upper jaw (DEMP), supported by 4 strips placed on the first premolars of the upper jaw and the first permanent molars. Thirteen (50%) patients of the 2nd group received treatment with a bone expander for bone expansion of the upper jaw (EJB). which was fixed directly on the palatine bone usmg 4 mimscrews. Results: In the EHCR group, a statistically significant decrease was observed in the external buccopalatal angle of inclination of the first maxillary premolars and the first permanent molars. In the ZEVC group, a statistically significant decrease was found only for the external buccopalatinal tilt: the angle of the right and left first premolars. Conclusions: Further research with a large sample size is needed to test the long-term stability of the achieved expansion by both devices.
