When is a Willis bite gauge typically used?

The Willis bite gauge is specifically designed to measure occlusal vertical dimension, which is a crucial aspect during the construction of complete dentures. It allows dental professionals to assess the relationship between the upper and lower jaws, ensuring that the dentures will fit properly and function effectively for the patient. Having the correct occlusal height is essential for both aesthetics and comfort, making the Willis bite gauge an invaluable tool in the process of creating full dentures.

In contrast, while root canal therapy, orthodontic assessments, and periodontal evaluations are all significant components of dental care, they do not typically require the use of a bite gauge like the Willis. Each of these procedures focuses on different aspects of dental health, such as treating infections in the pulp, assessing the position and alignment of teeth, or evaluating the health of supporting structures around the teeth, none of which directly involves measuring occlusal vertical dimensions as part of their standard protocols.
