OBJECTIVE

The aim of the study. To improve the effectiveness of patients’ treatment with narrow upper jaw by improving the stability of intraosseous devices.

MATERIALS AND METHODS

40 patients with the narrow upper jaw, from 12 to 40 years old, were treated. 50 self-drilling orthodontic miniscrews of each manufacturer, i.e. «BioRay», Taiwan, «Turbo», Russia, a total of 100 items, were inserted into a palate.

RESULTS

The greatest thickness of the cortical bone relative to the sagittal plane was observed at a distance of 6 mm from the incisor canal, which averages 6.32 mm. Relative to the transversal plane, the greatest bone thickness was observed 3 mm laterally from the median palatine suture and averages 7.62 mm. The smallest thickness of the mucous membrane of the hard palate is noted 6 mm distal from the incisor canal and 3 mm laterally from the palatine suture is on average 4.56 mm.

CONCLUSION

The protocol for determining the individual position of the miniscrew for each patient, taking into account all his anatomical features, is a necessary tool for clinical success.
