Rights and Permissions

To have stable orthodontic corrections, many malocclusions require the so-called permanent or fixed retention. Many modalities for quick, easier, and inexpensive placement of fixed retainers have been described in the literature. The present article describes a simple, cost-effective, and quick method using Kesling's separators for placement of bonded lingual retainer.

  Introduction Top

Since the introduction of bonded lingual retainer by Zachrisson,[1] its use has become commonplace and several methods [2] for delivering fixed lingual retainers have been introduced. However, the accurate, passive, and economical placement of the retainer has always been a matter of concern.[3]

For years Kesling's separators have been used for effective posterior teeth separation.[4] The purpose of the present article is to present a simple, cost-effective, and quick method using Kesling's separators for placement of bonded lingual retainer.

  Method of Placement Top

  1. Take impressions of arch, and pour it in stone
  2. Adapt 0.0175” stainless steel flexible spiral wires to the working casts
  3. Place Kesling's separators between the teeth to be bonded [Figure 1]a, [Figure 1]b, [Figure 1]c. For 3-3 placement of retainer, five separators are needed. For 4-4 placement, seven separators will be needed
  4. Straight arm of separator is placed cervical to the contact point of teeth and curved arch is slipped between the embrasure incisal to the contact point. This creates a window between the straight and curved arms on the lingual side of each contact point
  5. Slip the lingual retainer wire through the windows created by the Kesling's separators [Figure 1]d
  6. Pull the helix of the Kesling's separators labially so that the wire closely approximates the tooth surfaces. Excessive pulling should be avoided, because it can cause separation of concerned teeth
  7. Etch the lingual tooth surfaces, and bond the retainer as usual using light-cured flowable composite [Figure 1]e
  8. After complete bonding separators should be removed carefully without disturbing the bond
  9. After appropriate sterilization same separators can be reused.

Advantages of this technique include:

  • Saves considerable time, since Kesling's separators can be prepared beforehand and usually takes few minutes for preparation
  • Kesling's separators can be reused after chemical sterilization
  • Eliminates the need for a transfer tray [2],[3]
  • Allows precise placement and stabilization of the retainer wire
  • Requires minimal patient cooperation.
