Resumen
Introducción: Existen prótesis fijas sobre implantes dentales de diversos materiales y diseños. Las complicaciones mecánicas de mayor frecuencia son la delaminación y el desgaste de los materiales. Objetivo: Demostrar las ventajas de las prótesis con caras oclusales metálicas fresadas para reducir complicaciones mecánicas. Presentación del caso: Para tratar a una paciente de 80 años cuyos dientes presentaban periodontitis y caries, se planificaron dos prótesis fijas de arco completo sobre implantes. En la estructura se utilizó la tecnología CAD/CAM con técnica de fresado. Una vez colocadas las prótesis pulidas en boca de la paciente, se observó que cuando sonreía, las caras oclusales metálicas fresadas eran imperceptibles, además de reducir el riesgo a la delaminación y mejor ajuste pasivo. Conclusiones: La tecnología CAD/CAM permite obtener caras oclusales metálicas fresadas que favorecen la reducción de complicaciones mecánicas, y un mejor ajuste pasivo a costos competitivos.
