What effect does reduced overjet of posterior teeth have on complete dentures?

A reduced overjet of posterior teeth in complete dentures leads to an increased tendency for cheek biting. This is because a reduced overjet often results in a closer approximation of the denture teeth, which can imply that there is less space between the cheek and the posterior teeth during functional movements such as chewing or speaking. As a result, individuals with this configuration may unintentionally come into contact with the cheeks, causing discomfort or even injury to the soft tissue.

The dynamics of the oral cavity during movement can create a situation where the cheeks are more likely to be pinched or bitten, especially during lateral movements or when the patient is consuming food. This clinical consideration is essential for designing dentures to ensure that they not only fit well but also function effectively without causing harm to the surrounding oral tissues.

Other options might suggest factors such as wear or stability, but these are less directly influenced by reduced overjet in the same manner as the tendency for cheek biting. Thus, it highlights the importance of proper dimensions in denture construction to enhance comfort and avoid complications.
