|
What is the insertion for the Temporalis?
|
Coronoid process
|
|
|
What is the origin of the Temporalis muscle?
|
Temporal Bone
|
|
|
Action of Temporalis?
|
Retrude and elevate
|
|
|
Origin of Lateral Pterygoid?
|
Maxilla
But for boards its the lateral surface of pterygoid plate of sphenoid |
|
|
Insertion of Lateral Pterygoid?
|
Condylar process
|
|
|
Insertion of medial pterygoid?
|
Angle of manidble
|
|
|
Origin of medial pterygoid?
|
Maxilla
|
|
|
Origin of Masseter?
|
Zygomatic process
|
|
|
Insertion of Masseter?
|
Angle of manidble
|
|
|
Muscles that close mouth?
|
Anterior Temporalis, Masseter and Medial Pterygoid
|
|
|
Muscles that open mouth?
|
Lateral pterygoid and anterior digastric
|
|
|
Relevance of OOOOO and EEEEE?
|
allows us to see masseteric notch being formed
|
|
|
Importance of Masseteric notch?
|
Allows denture to stay in place DURING SPEECH when you place the notch in the denture
|
|
|
What 2 muscles form masseteric notch?
|
Buccinator and Masseter
|
|
|
What happens to denture if you lack notch in denture and you say ooooo and eeee?
|
Denture moves forward and falls out
|
|
|
What 2 muscles determine lower border of denture?
|
Mylohyoid and Genioglossus
|
|
|
Name of concavity that is lateral inferior to mylohyoid?
|
Retromylohyoid space. You can place mirror and ask for an ooo and eee to check for mirror displacement
|
|
|
In profile view, what does the base of the denture rest on?
|
geniohyoid
|
|
|
Force caused by compression of denture muscles?
|
Seal = mucodynamic
|
|
|
Mucostatic vs Mucodynamic?
|
Mucostatic tissue does not move. Mucodynamic tissue does move
Remember that Mucodynamic tissue AKA muscles are often COMPRESSED to make a SEAL |
|
|
Muscles that border upper denture?
|
Tensor veli palatini, Levator veli Palatini, Orbicularis Oris & Buccinator
|
|
|
When soft palate lifts when a person says ahh what happens to denture?
|
If the muscles are not sealed air will get in
Causes loss of ATM and denture falls out |
|
|
What happens to patient philtrum when edentualist?
|
They lose it
|
|
|
What happens to orbicularis oris when patient is edentualist?
|
Collapses. No teeth nor alveolus to keep it place
|
|
|
Moving tongue activates what muscles?
|
floor of mouth = mylohyoid
|
|
|
What pushes on dentures laterally?
|
Buccinator and Tongue. Neutral zone is when both muscles cancel each other out = no net movement of dentures
|
|
|
Buccal shelf?
|
Increases adhesion because it increase surface area
|
|
|
Retention is a function of?
|
ATM, Adhesion & Cohesion
|
|
|
Undercuts increase cohesion or adhesion?
|
Cohesion = closness. Saliva on denture gets closer to saliva of tissue
|
|
|
Which undercuts do we block out with wax?
|
Posterior undercuts can be blocked to improve estethics but Anterior under cuts provide more closeness = cohesion so can never be blocked
|
|
|
Retromylohyoid Space
Massteric Notch below |
