  Abstract 


Relapse of the midline diastema is one of the most common postorthodontic complaints. Although numerous methods have been cited in literature, we propose an easy, time-saving, cost-effective, and reliable method for its correction using an elastomeric ring separator.

  Introduction Top


Midline diastema, though a common problem,[1] is extremely annoying to most people, especially when it reappears in patients who have completed their orthodontic treatment.[1]

In general, the most popular form of retention for midline diastema cases is indefinite fixed retention.[2] Sometimes, there are breakages in fixed or removable retention which goes unnoticed by the patient. The patient only realizes after there is a visible opening of the midline space.

There are many options available for correction, namely, removable appliance, fixed appliance, elastics, composite build-up, veneers, and brass wire.[3],[4]

Here, we suggest a fast and effective way of closure of the relapsed diastema [Figure 1]a with the use of elastomeric ring separator for diastemas 1–1.5 mm wide.

  Procedure Top


The patient is examined to measure the amount of diastema space. This method is ideal to close diastemas up to 1.5 mm. Check the effect of digital pressure on the two central incisors by pushing them toward each other, by applying pressure on the distal surfaces of both the incisors. If this shows some reduction in space, then an elastomeric ring separator can be used to close the space.

A proper separator placing plier is selected; it should have maximum beak separation more than 18 mm (as the average mesiodistal dimension of maxillary central incisor is 8.5–9 mm).

Then, an elastic ring separator is taken and prestretched 2–3 times to reduce the amount of force generated. Then, it is threaded in the distal embrasures of both the central incisors [Figure 1]b. Within minutes, closure of the midline space is seen. Next, the palatal surfaces of the incisors are etched and a fixed retainer is bonded. The flexibility of the elastic separator allows the operator to apply and contour the composite properly to the palatal surface. After bonding, the separator is removed using an explorer. The whole procedure can be completed in 15–20 min [Figure 1]c and [Figure 1]d.


  Discussion Top


Many different techniques have been used for correction of relapsed midline diastemas. One such single sitting space closure technique using brass wire[3] has been suggested in literature. However, use of brass wire makes the procedure more traumatic[5] with chances of gingival lacerations; moreover, the threading and tightening of brass wire is often uncomfortable to the patients.[5] Correction using elastomeric ring separators followed by stabilization with fixed retainer is a reliable, easy, time-saving procedure, especially for relapsed diastema space up to 1.5 mm.


  Conclusion Top


The main advantage here is the short procedure, time saving, and cost-effectiveness.
