Soft tissue considerations in the management of diastemas

Management of the diastema changes the mesio-distal dimensions of the clinical crown resulting in a discrepancy at the location of the zenith points as well as the papillae. Thus, management requires relocation of the zenith points as well as regeneration of the papillae. Treatment of the central diastema is a further challenge due to the unique nature of the interdental space between the two central incisors. Building up diastemas may considerably change the crown proportions due to unilateral build-up of the clinical crown. This may lead to further discrepancy between the zenith point and the midline of the teeth, depending on the extent of the diastema to be treated.
