Medidas de inclinación de la trayectoria condílea y del ángulo de Bennet de la población occidental, actualización y revisión bibliográfica

Zusammenfassung

Introduction: Currently any prosthodontic treatment involves the use of articulators for diagnosis and prostheses fabrication. The ideal protocol would be to individualizing each case getting the actual condylar path inclination (CPI) and Bennet angle. Although dentists used to work with the stablished standard values. Predeterminated articulator settings have been the same since they were instituted without any change. The aim of this study was to verify that these average values were still valid today. Material and methods: Collection of real CPI and Bennet angle values review from the literature between 1959 and 2011. Thirty four studies were selected from large population samples for a total of 2142 individual condylar values. Results: Large differences between the studies reviewed were found, from average values CPI of 30.1 degrees in 1960 to 57.8 º, 2009. Conclusions: It was observed a gradual increase in average CPI over the years, which indicates vertical chewing movements over lateral ones. These results are far from those proposed for semi-adjustable articulators. Therefore, these standard values must be reinstated with higher figures rather than relying on overage values.
