Resumen
Objetivo: Analizar la posición del punto A en pacientes clase II con extracciones de primeros premolares superiores tratados con técnica de Ricketts y MBT en pacientes tratados en la clínica de ortodoncia de la escuela de postgrado de la Universidad de Guayaquil en el periodo 2013 al 2015. Metodología: muestra 14 pacientes, edades comprendidas entre los 11 y 31 años, que cumplieron con los criterios de inclusión. Tipo de investigación: explicativo, relacional, descriptivo, observacional. Resultados. De acuerdo al tiempo de tratamiento observamos que en la técnica Ricketts se demora de 21 a 40 meses el tratamiento de ortodoncia en un 43%. Analizando el ángulo SNA con la técnica MBT llega a la norma en un 14,3% al final del tratamiento. Sin embargo, en la convexidad facial con la técnica MBT aumenta en un 100% al final del tratamiento. Conclusiones: el estudio permitió correlacionar los pacientes con extracciones de primeros premolares superiores, tratados clínicamente con técnicas de Ricketts y MBT. En cuanto al sexo de los pacientes tratados demuestran prevalencia del sexo femenino. Con respecto a la edad en edades comprendidas entre los 21 y 30 aumenta la tendencia a realizarse tratamientos de ortodoncia. En cuanto al ángulo SNA y a la convexidad facial vemos una disminución con la técnica MBT al final del tratamiento, por lo tanto, podemos decir que el cambio del punto A es más notable su reducción con esta técnica.
Objective: To analyze the position of point A in class II patients with extractions of the first premolars treated with Ricketts technique and MBT in patients treated in the orthodontic clinic of the postgraduate school of the University of Guayaquil in the period 2013 to 2015. Methodology: It shows 14 patients, aged between 11 and 31 years, who met the inclusion criteria. Type of research: explanatory, relational, descriptive, observational. Results. According to the treatment time, we observed that in the Ricketts technique, the orthodontic treatment was delayed from 21 to 40 months by 43%. Analyzing the SNA angle with the MBT technique reaches the norm in 14.3% at the end of the treatment. However, facial convexity with the MBT technique increases by 100% at the end of treatment. Conclusions: the study allowed to correlate patients with extractions of the first upper premolars, treated clinically with Ricketts and MBT techniques. As for the sex of the treated patients, they show a prevalence of the female sex. With regard to the age between the ages of 21 and 30 the tendency to perform orthodontic treatments increases. Regarding the SNA angle and the facial convexity we see a decrease with the MBT technique at the end of the treatment, therefore, we can say that the change of point A is more remarkable its reduction with this technique
