After removing the post, the root canal filling was easily removed by manual instrumentation with reamers and Hedstroem files. A working length radiograph was taken with the incisal edge of tooth 31 as a reference level. The canal was then prepared to size 70 / 19 mm. Because of resorption it was difficult to build a good apical box. The canal was filled with calcium hydroxide and sealed with a tight temporary filling.
