Abstrakt:	The Aim of the Study: Was to analyze the effectiveness of the use of Pitts Broad and early elastics in the treatment of patients with narrowing and deformation in dentition. Materials and Methods: The results of orthodontic treatment of 46 adult patients with narrowing and deformation in dentition are presented. Patients were separated in 2 groups, depending on the algorithm of treatment: group 1 - using the braces of passive self-ligation, Pitts Broad and early short elastics; group 2 - using ligature braces and archwires Orthos. Results: Biometric analysis of the diagnostic models of the 1 st group after treatment showed a significant increase in the area of the premolars on the upper (between premolars - 39.8±0.4 mm, between molars - 48.3±0.5 mm) and lower (between premolars - 37.1±0.5 mm, between molars - 46.3±0.6 mm) jaws compared to the data before treatment. Biometric analysis of the diagnostic models of the 2 d group showed that expansion in the area of the molars was achieved in a much smaller volume in the upper and lower jaws, compared with the 1 st group (upper jaw: between premolars - 35.7±0.4 mm, between molars - 43.5±0.5 mm; lower jaw: between premolars - 33.2±0.3 mm, between molars - 42.3±0.5 mm). Conclusion: The passive self-ligation system in combination with protocol of Pitts Broad already contributes the expansion of dentition in aesthetically significant areas (distal regions) in the early stages of treatment. Using of early light elastics provides an early control of the lateral tooth torque, which allows achieving a harmonious and wide smile at the end of treatment.
