Resumen
Objetivo: Evaluar la capacidad de la tomografía transversal para realizar las valoraciones radiográficas de las medidas preliminares en implantes de oseointegración del maxilar inferior, en relación con las medidas físicas realizadas en mandíbulas disecadas.Materiales y métodos: Se utilizaron cinco mandíbulas humanas disecadas con características diferentes y 45 cortes tomográficos convencionales. A cada radiografía tomada de mandíbula, se le realizó las medidas correspondientes. Se hicieron cortes transversales físicos, donde previamente se colocaron indicadores radiográficos del sitio exacto del corte. Posteriormente, se realizaron las mediciones con reglas milimetradas y calibradores especiales. Aplicando la metodología de Bland y Altman, se evaluó el acuerdo entre las mediciones físicas y radiográficas, previa evaluación de la concordancia intraevaluador.Resultados: Se detectó una buena reproducibilidad intraevaluador (P>0.79) y concordancia entre evaluadores (CC1>0.84). Las mayores diferencias entre las mediciones radiográficas y físicas se detectaron para las mediciones verticales (V2 y V4) con una diferencia promedio de (-1.36 y 1.30) y con unos límites de acuerdo entre (-6.26 y 3.66) y (-6.47 y 3.76), respectivamente.Conclusión: Existe un buen acuerdo entre las mediciones físicas y radiográficas por lo cual la Tomografía puede utilizarse como medio diagnóstico previo a la colocación de implantes dentales.[Pérez SL.

Objective: To assess the accuracy of the transversal tomography to make the radiographic evaluations of the preliminary measures in osseointegrated implants in the jaw, in relation to the physical measures made in dissected jaws.Materials and methods: Five human jaws were dissected with different characteristics and 45 conventional tomographic cuts were used. To each x-ray taken from the jaw, it was made the corresponding measures. Physical cross sections were made in the previously radiographic indicators of the exact site of the cut. Later, the measurements with millimeter rulers and special calipers were made. Applying the methodology of Bland and Altman, the agreement between the physical and radiographic measurements were evaluated.Results: The greater differences were between the radiographic and physical measurements detected for the vertical measurements (V2 and V4) with a difference average of (-1.36 and 1.30) and with limits in agreement between (-6.26 and 3.66) and (-6.47 and 3.76), respectively.Conclusion: A good agreement between the physical and radiographic measurements existed; thus the tomography can be used as average previous diagnosis to the positioning of an implant.
