What happens when excessive occlusal clearance occurs?

When excessive occlusal clearance occurs, it leads to a compromise of the occlusal relationship. This situation arises when there is too much space between the opposing dental surfaces, which can negatively impact how the teeth come together during functional activities such as biting and chewing. Proper occlusal clearance is critical for maintaining a stable and functional bite.

If there is excessive clearance, it may result in altered forces on the teeth and temporomandibular joint, potentially leading to issues such as discomfort, difficulty in achieving proper alignment, and an inability to adequately stabilize the restoration in place. Moreover, this can lead to changes in the patient's bite over time, resulting in further dental complications.

The other options suggest improvements in retention, decreased risk of fracture, or increased aesthetic value, which do not align with the implications of excessive clearance. Instead of enhancing the benefits of a restoration, excessive occlusal clearance actually creates challenges that necessitate careful management.
