Orthodontic intervention for dental changes induced by ‘off the shelf’ and custom-made occlusal splint therapy for bruxism: a report of two cases

Occlusal splint therapy for bruxism can be provided in a professional setting by a dentist; however, patients can also purchase ‘off the shelf’ appliances. Where appliances do not cover all the occlusal surfaces, overeruption of uncovered teeth can occur, leading to changes to the occlusion. Two patients are presented who noticed significant changes to their occlusion by way of lateral/posterior open bites and sought orthodontic treatment to reverse these. The changes had occurred after short- and long-term use of ‘off the shelf’ and custom-made occlusal splints, respectively. The patient in Case 1 was treated with pre-adjusted edgewise appliances and inter-maxillary elastics, while the patient in Case 2 completed treatment with Invisalign aligners (Align Technology, CA, USA). When patients seek occlusal splint therapy, they should be advised to see a dentist to have an appropriate custom-made device fitted to cover all teeth to reduce the risk of unwanted changes to the occlusion. CPD/Clinical Relevance: Occlusal splint therapy for bruxism is best provided in a professional dental setting to avoid overeruption of uncovered teeth and other occlusal changes.
