Labiodental Consonant Sounds

• Labiodental sounds are produced by the interaction of the lower lip and the upper teeth. The sounds "f" and "v" are classic examples of labiodental consonants. "Ph" is often considered a variant of "f" in phonetics.

Explanation: Natural dentition can typically withstand average biting forces of around 600N, which is significantly higher than the 110N that complete dentures can generally handle. Complete dentures rely on muscular and bony support and are limited by the resiliency of the soft tissues in the oral cavity.

The distal end of the complete denture should be 1-2 mm posterior to the vibrating line.

The mandible can be made into retruded position for recording the centric relation by all of the above: protrude and retrude mandible alternately, repeating the word "M" and relaxing, making the tongue touch the posterior palate.

The Camper’s plane is a facial reference plane that passes from the ala of the nose to the superior edge of the tragus of the ear. This plane is used in facial and cranial anatomy to describe the orientation of various structures and is often referenced in the field of orthodontics and surgery. It is useful for assessing the facial profile and the relationship between the nose, ears, and other facial features.
