ClinCheck views demonstrating the different proposed treatment plans. (a) Treatment plan no. 1: close all spaces in lower anterior region and accept the TSD tooth size discrepancy. (b) Treatment plan no. 2: evenly distribute spaces between lower incisors to correct the TSD tooth size discrepancy.

Both of the possible solutions are illustrated in (Figures 6(a) and 6(b)) which were considered at the treatment planning stage. The TSD has not been corrected; hence the occlusion cannot be improved (see Figure 6(a)).  The pre-restorative orthodontics allows for the incisors to be built up to the correct mesiodistal widths with composite restorations. The correction of the TSD helps to correct the overjet and improve arch coordination with the adjunct of minimally invasive dentistry (see Figure 6(b)).
