What is the main concern when assuming an increase in interocclusal space?

The main concern when there is an increase in interocclusal space is the potential for cheek biting. When the interocclusal space increases, the relationship between the upper and lower jaws changes, which can lead to misalignment during functional movements such as chewing and speaking. This misalignment may result in the cheeks being positioned closer to the occlusal plane, making them more susceptible to being bitten when the patient closes their mouth.

This risk of cheek biting is particularly relevant in dentistry and prosthodontics, where adjustments to occlusal relationships are common. It highlights the importance of careful assessment and management of occlusion and interocclusal space in both natural dentition and the design of dental prostheses to ensure patient comfort and function.

While the other concerns such as loss of tooth structure, compromised periodontal health, and reduced occlusal harmony are valid considerations in dental practice, they do not primarily address the immediate functional implications that arise from increased interocclusal space. Cheek biting is a direct consequence of altered occlusion, making it the most pertinent concern in this scenario.
