Occlusion Vertical Dimensions refer to the measurements and relationships that define the vertical position of the upper and lower jaws in relation to each other when the teeth are biting together. It is an important aspect of dental occlusion, which is the alignment and contact between the teeth in both the resting and functional positions of the jaw.
The occlusion vertical dimensions are determined by several factors, including the height and shape of the teeth, the condition and thickness of the jawbone, and the muscles and ligaments that control jaw movement. These dimensions are essential for maintaining proper chewing, speaking, and overall oral function.
There are three main components that make up the occlusion vertical dimensions: the rest position, the occlusal position, and the functional position. The rest position is the natural position of the jaw when the teeth are not in contact, and it serves as a reference point for other measurements. The occlusal position refers to the contact between the upper and lower teeth when biting down in a normal closed position. The functional position, on the other hand, involves the movements of the jaw during activities such as chewing and speaking.
Disruptions in the occlusion vertical dimensions can lead to various dental issues, including malocclusion (misalignment of the teeth), jaw pain, and difficulty in biting and chewing. Dentists and orthodontists often assess and measure these dimensions to diagnose and treat problems related to tooth and jaw positioning.
In summary, occlusion vertical dimensions pertain to the vertical relationship and measurements of the upper and lower jaws when the teeth are in contact, and they play a significant role in dental occlusion and oral function.
