ABSTRACT

Introduction: the twin block system is a natural consequence of the evolution of the treatment with functional devices and represents a fundamental transition from single-piece devices, which restrict abnormal function, to devices that favor normal function.
Objective: to evaluate the results of the treatment of dentomaxillofacial anomalies with standard twin blocks.
Method: we performed a quasi-experimental modality before and after without a control group, in 10 patients who were admitted to the orthodontic clinic of the University Clinic of Stomatological Specialties Manuel Cedeño, from November 2016 to January of 2018, to which standard twin blocks were installed and the changes obtained 9 months after the start of the active treatment phase were determined by means of the clinical examination and the cephalometric analysis of the lateral cranioradiographies of the skull.
Results: the mandibular position was corrected in 80 % of the patients, the class II skeletal classification and the projection was modified in 90 % and 70 %; respectively, as well as an improvement of the profile in 60 %; with a statistical significance of p = 0.000.
Conclusions: there were favorable clinical and cephalometric changes as well as an adequate profile and prominence, which influenced the improvement of the occlusion and the aesthetics of the patients.
