THE AIM OF THE STUDY

Was to improve the quality of symptomatic diagnostics of mesial occlusion.

MATERIALS AND METHODS

The object of our epidemiological study was 2842 schoolchildren aged 6 to 18 years, and 458 conclusions of Professor Yu. M. Malygin to patients who sought consultative assistance. The analysis of the archive of diagnostic models of jaws of the Department of Orthopedic Dentistry of the Central Institute of Orthopedic Medicine and the Department of Orthodontics of the Russian Medical Academy of Postgraduate Education in the volume of 20.000 pairs and a sample of 2490 models of jaws of patients with mesial occlusion were conducted, and then an in-depth biometric study of 205 pairs of models of jaws of patients with permanent mesial occlusion was carried out.

RESULTS

Clinical and epidemiological characteristics of mesial occlusion showed the percentage of occurrence among bite anomalies 5.6+2.03; it occurs more often in boys than in girls and more often in mixed dentition than in permanent dentition. The efficiency of determining individual types of mesial bite varied from 100% to 14%, and on average the visual diagnosis was established correctly in 44.7%. A comparative analysis of 205 pairs of jaw models with mesial bite relative to the norm showed that differences in 39 parameters out of 43 were not statistically guaranteed, so the inclinations of the anterior teeth were also studied, and then 9 typical types of mesial bite were determined using the “diagnostic key” of Yu. M. Malygin and the algorithm we developed.

CONCLUSION

An algorithm for symptomatic diagnostics has been developed, which made it possible to identify and systematize typical types of mesial bite.
