Which is the most likely finding in a patient with signs of occlusal dysfunction?

Loss of vertical dimension is a common finding in patients with excessive wear or occlusal dysfunction. It may result from parafunctional habits (e.g., bruxism) or aging, leading to decreased facial height and occlusal collapse. Heavy post occlusion is less likely unless due to an ill-fitting prosthesis. Erosion of maxillary buccal dentition suggests acid exposure rather than occlusal dysfunction.
