Class 3 Malocclusion

a. A Class III Malocclusion is when the 1st mandibular molar is more than one tooth ahead of 1st molar of the maxilla. It is essentially when top teeth are behind the bottom teeth causing an underbite.
b. A phoneme that may be affected /θ/. For example, a person with a Class III Malocclusion would potentially say “sree” for “three” because they are not able to correctly articulate /θ/ in “three”. With a Class III Malocclusion, the articulation would be off, but speech is likely intelligible.
2. Explain the active process of shedding of deciduous teeth (2 points)
a. Around 6-9 months, deciduous (milk teeth) teeth erupt. The deciduous teeth start to shed around 6 years old. First the incisors shed. Then the canines and premolars. Finally, the …show more content…

In Gilbert et al and Kairaitis, they discuss how an elephant trunk is a muscular hydrostat. The trunk is considered a muscular hydrostat because the structure is made up of almost entirely muscle and there is no skeletal support. The elephant trunk has the ability to move in almost all directions, completing similar movements as the human tongue.

a. Airway resistance is the friction related to the flow of air. There is always going to be resistance because of the root of the tongue, velum, lips, teeth, and uvula. Acoustic impedance is the opposition to the flow of sound energy waves. When airway resistance is high, acoustic impedance is high.

i. The articulator involvement was different because they contact was not the same, which created a different pronunciation of the number. When then pen was in between my teeth, I wasn’t able to create the same movement that I do when I typically produce the numbers. For example, I produced “thwee” for “three”. I could not correctly produce three because my tongue was not able to make contact with my alveolar ridge. The active forces in normal counting go directly to the correct articulators for producing the sound. The active forces for constrained counting had to go around the pen, which allowed the word to be produced, it just sounded different than the normal
