Occlusal Problems

Orthodontics can be used to try and produce an optimal occlusion, and there are many situations in which this can be used.2 The occlusion can be adjusted to provide canine guidance, and eliminate non-working side interferences. In situations where anterior open bites exist, it is occasionally possible to close these down without the need to resort to surgery.3

Sometimes the occlusion can damage the teeth and supporting tissues. Figure 8 is an example of a patient with a unilateral cross bite extending from the upper central incisor to the terminal molar on the right hand side. This traumatic occlusion had produced substantial tooth wear. Treatment was carried out using an upper fixed appliance in conjunction with a quad helix to expand the upper arch, correct the cross-bite and align the teeth. At the completion of treatment the incisal tips were restored with composite.
