After consolidation of the diastemata between UR1-6 with power chains following UR2 cross bite correction (Fig.10), the restoration space for UL1 seems to be too large (Fig.11). Next visit, check the midlines, take 1-2 PAs for #7-9 and determine whether a straight abutment should be changed back and whether composite should be placed UR1 mesial to reduce the space.
