ABSTRACT

Background: The treatment of mandibular retrognathia in early ages is performed with a variety of functional orthopedic devices. The Truax Corrector II is one of the devices with internationally proven efficacy and little studied in Cuba. Objective: Describing the morphological changes in patients with mandibular retrognathia treated with the Truax Corrector II. Methodology: A cross-sectional study was made from December 2009 to 2010 in the Provincial Dental Clinic of Sancti Spiritus. The sample consisted of 12 children from 7 to 10 years with mandibular retrognathia and in a period of active growth. The variables studied included: overjet and overbite of incisors, transverse width of both jaws and right and left molar ratios. The tests used included the comparison of means for paired samples, that of Wilcoxon’s signed ranks and Monte Carlo algorithm. Results: In 100% of the patients occurred an average decrease of 3.75 mm in incisor overjet, an increase of jaw transverse diameters (0.8 mm the upper and 1.4 mm the lower) and an average drop of 0.66 mm in incisor overbite. The right and left molar ratios evolved to neutroclusion in 83.3% of patients studied. Conclusions: All patients treated with the Truax Corrector II showed a satisfactory outcome, with improvement of the morphological variables studied.
