MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Contradictory results are still reported on the influence of dental occlusion on the balance control. While most literature have evaluated this relationship in static conditions with inconclusive results, the topic is still a matter of debate. However, less research has focused on the correlation of dental occlusion and balance control in unstable surfaces, even though the higher sensitivity of the unstable platforms to examine individual responses to translational and angular perturbations.

Moreover, when we talk about the influence of dental occlusion on the body balance, the study of the specific malocclusal traits influencing balance control should be of extremely importance to apply the proper treatment.

Our study was focused on the influence of dental occlusion and specific malocclusal traits on the body balance control at extreme levels of stability. We found that body balance was significantly influenced by dental occlusion in unstable conditions.
Moreover, specific occlusal traits significantly influencing postural control were: Angle Class, crowding, midline deviation, crossbite, anterior open bite and overjet.

Dental Occlusion Can Influence Standing Balance

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Over the last few years, a growing interest has focused on the potential correlation between the stomatognathic system and the body balance. While this relationship is still a subject for debate, it is well known that sensory information contributes differently on the postural control regulation depending on the conditions of the surface area. Therefore, we hypothesized that dental occlusion may contribute differently on the body balance control depending on the stability condition (stable versus unstable) and that influence might be more evident in fatigue conditions due to reorganization of the sensory information sources.

In the current study we aimed to determine whether:

(i) dental occlusion influences body balance in stable and unstable surfaces, and

(ii) the influence of dental occlusion on the balance control comes strongly into effect under fatigue conditions.

Our results showed that dental occlusion influenced balance control, at unstable level, both at rest and fatigue condition. However, when measuring at stable level, the influence of dental occlusion only reached significance in fatigue condition.
