AIM: to evaluate the relationship between the disc displacement and the vertical skeletal facial type in adolescent patients with temporomandibular disorders. METHODS: The patients were divided in 3 vertical skeletal facial type: Normodivergent, Hypodivergent and Hyperdivergent based on lateral cephalogram. The disc position was classified by MRI in: Normal (N), Disc Displacement with reduction (DDwR) and Disc Displacement without Reduction (DDwoR). The Chi2 test was performed for the relationship. RESULTS: 50 patients adolescents were evaluated (18 Normodivergent, 16 Hypodivergent and 16 Hyperdivergent). DDwR occurred in 55% of Normodivergent and in 40% of Hypodivergent patients and DDwoR occurred in 73% hyperdivergent patients (P 0.001). CONCLUSIONS: this study suggests that hyperdivergent patients have a greater risk of having a DDwoR, so an assessment of this condition is necessary during the diagnosis and planning of orthodontic treatment in growing patients.

Abstract

AIM: to evaluate the relationship between the disc displacement and the vertical skeletal facial type in adolescent patients with temporomandibular disorders. METHODS: The patients were divided in 3 vertical skeletal facial type: Normodivergent, Hypodivergent and Hyperdivergent based on lateral cephalogram. The disc position was classified by MRI in: Normal (N), Disc Displacement with reduction (DDwR) and Disc Displacement without Reduction (DDwoR). The Chi2 test was performed for the relationship. RESULTS: 50 patients adolescents were evaluated (18 Normodivergent, 16 Hypodivergent and 16 Hyperdivergent). DDwR occurred in 55% of Normodivergent and in 40% of Hypodivergent patients and DDwoR occurred in 73% hyperdivergent patients (P 0.001). CONCLUSIONS: this study suggests that hyperdivergent patients have a greater risk of having a DDwoR, so an assessment of this condition is necessary during the diagnosis and planning of orthodontic treatment in growing patients.
