Resumen
Objetivo: Informar la cirugía de injerto gingival libre (IGL) en el diente 33 asociada a láser de baja potencia. Detalles del caso: Paciente masculino de 23 años, no fumador y sin cambios sistémicos, acude a un colegio con el principal síntoma de hipersensibilidad dentinaria en el diente 33. Al examen clínico el paciente presentó recesión gingival en el diente 33, midiendo 2mm de profundidad al sondaje, Mucosa fina queratinizada, con diagnóstico clínico de ITR de El Cairo. Se realizó anestesia local y se realizaron las incisiones, con cuchilla 15c, en bisel interno a 45° intrasulcular y relajante, formando un colgajo trapezoidal y desprendimiento con profundización del vestíbulo mediante un separador de mudas 2-4. Luego, en la región palatina, se retiró el injerto autógeno epitelial y se adaptó a la zona receptora y se suturó con puntos simples hasta su total estabilidad. En el postoperatorio se prescribieron analgésicos y corticoides, además de láser rojo a 2 julios por punto en zona donante y receptora. Consideraciones finales: Con base en los resultados clínicos, se puede considerar que EGL es un excelente injerto para ganar mucosa queratinizada, pero no para cubrir.
