Preoperative planning with simulation

Ra­pid pala­tal expan­sion –
reliably achieve symmetrical results

Simq RPE

One of the main risks of rapid palatal expansion (RPE) is that the face is widened asymmetrically by the distractor, which also causes the occlusion of the teeth to no longer fit. Simulation-based optimization can be used to align the surgical incision to minimize the risk of asymmetric opening. Medical device manufacturers launching distractors can use our software to enhance their products with an additional planning service.
