Which is not a measurement used in constructing a complete denture?

1. Height of occlusion

2. Vertical dimension

3. Intrusion

4. Centric occlusion

The correct answer is: Intrusion

In the context of constructing a complete denture, the height of occlusion, vertical dimension, and centric occlusion are all critical measurements used to ensure that the dentures fit properly and function effectively within the oral environment. Height of occlusion refers to the distance between the maxillary and mandibular arches when the occlusal surfaces of opposing teeth are in contact. This measurement is essential for achieving proper alignment and esthetics in the denture. Vertical dimension is a measure of the distance between two points in the vertical direction within the oral cavity, often measured at rest and during occlusion. Maintaining an appropriate vertical dimension is important for facial support and comfort. Centric occlusion, also known as maximal intercuspation, describes the occlusion of the opposing teeth when they interdigitate maximally. This measurement is important for achieving harmonious and functional relationships between the dental arches. Intrusion, on the other hand, refers to the movement of a tooth or teeth in an apical direction towards the alveolar bone, which is not a measurement relevant to complete dentures. Instead, intrusion pertains more to orthodontic mechanisms and tooth movement, and is not a factor considered when constructing complete dentures. Therefore, it is correctly identified as not being used in this
