Why is it essential to maintain interocclusal space in complete dentures?

Maintaining interocclusal space in complete dentures is crucial primarily because it aids in facilitating swallowing and speech. Proper interocclusal space, which refers to the space between the upper and lower jaws when the mouth is closed, ensures that the patient is able to chew efficiently and speak clearly. If the interocclusal space is inadequate, it can lead to difficulties in articulation, where certain sounds may become hard to pronounce. Additionally, limited space can impede effective swallowing, as the positioning of the dentures plays a role in the proper mechanics involved in these actions.

Swallowing and speech are significantly affected by how well the dentures fit and allow for natural movement and function of the jaws. Therefore, maintaining an appropriate distance between the occlusal surfaces is essential for the overall comfort and functionality of complete dentures, contributing to the quality of life for the wearer.
