When the permanent crown is seated initially 2.5 months postop, the mesial contact is slightly tight and the occlusion is high.  Bitewing shows the distal open margin (Fig.9 >).  After mesial contact adjustment, the patient feels that the occlusion is better.  With further occlusal adjustment, the crown is cemented without distal open margin (Fig.10).  The patient will return to her home country for 3 months.
