In lingual orthodontics, it can be difficult to get the correct or ideal force levels for space closure, owing to the reduced inter-bracket distance. The main ways to close space are with a continuous elastomeric chain (Figure 1), or closing loops (Figure 2). Power chains are useful but are sometimes not strong enough to achieve space closure, especially in the anterior region. The author has found that a pre-stretched elastomer (module) can be a useful, simple, and easy way to get the desired outcome. (Figures 3–5).
Place metal ligatures to secure the wire. This is also a fail-safe mechanism to prevent rotations in case a module breaks.
A standard module is pre-stretched and placed over two wings on two separate teeth. It is connected to the adjacent teeth as required to close residual space.
To avoid space appearing distally, place a laceback in the posterior segments.
