What does the Caninus muscle do?
The levator anguli oris (caninus) is a facial muscle of the mouth arising from the canine fossa, immediately below the infraorbital foramen. It elevates angle of mouth medially. Its fibers are inserted into the angle of the mouth, intermingling with those of the zygomaticus, triangularis, and orbicularis oris.
What is depressor Anguli?
The depressor anguli oris muscle (triangularis muscle) is a facial muscle. It originates from the mandible and inserts into the angle of the mouth. It is associated with frowning, as it depresses the corner of the mouth.
What is the function of the levator anguli oris muscle?
A muscle used in facial expression, primarily for smiling, the levator anguli oris elevates the angles of the mouth. The levator anguli oris originates roughly 1 cm inferior to the infraorbital foramen from the canine fossa of the maxilla and is located in the deepest layer of mimetic muscle.
What is the Modiolus of mouth?
The modiolus is defined in various dental dictionaries as a point lateral to the corner or angle of the mouth where certain muscles of facial expression converge (Jablonski, 1982; Manhold and Balbo, 1985; Harty and Ogston, 1987).

Where are the Frontalis?
Generally, the frontalis inserts at the eyebrow dermis and terminates laterally at the temporal ridge, but there is some variance and occasionally may terminate more medially as well. [10][11] While overall, it is a thin muscle with high vascularity, the bulk of it is located right above the brow.
What is the function of Mentalis?
It acts as the primary muscle of the lower lip. The mentalis originates from the mandible (lower jaw) and runs vertically from below the lower lip to the lower part of the chin. This muscle provides stability to the lower lip to allow it to pout. It causes protrusion of the lower lip and elevates the skin of the chin.
What does Anguli Oris mean?
Depressor means ‘to lower’, anguli is Latin for ‘angle’, and oris is Latin for ‘mouth’. Therefore, depressor anguli oris can be loosely translated to mean ‘lower the mouth at an angle’.
What does the name levator Anguli Oris tell us?

When was canine retraction by removable appliances invented?
3. HISTORICAL PERSPECTIVE Canine retraction by removable appliances was done as early as the late 19th century various kinds of springs were developed for simple pushing back of canine teeth.
What are the different types of canine retraction?
7. Canine retraction mechanism can be generally classified into 2 types Group A : Sliding the canine tooth along the arch wire (Friction) Group B : Distal movement of the canine with the arch wire (Frictionless) GROUP A : Sliding the canine along the arch wire : Advantages Minimal wire bending time. No running out of space for activation.
Are there any ways to retract canine teeth?
2. INTRODUCTION There are numerous methods of retracting the canine teeth with fixed appliances. Fixed appliances are necessary to treat malocclusion which require some bodily movement or rotation of the teeth to produce and aesthetic, functional and near ideal occlusion as is possible.
When did Charles J Burstone start canine retraction?
RICKETTS In 1950, started sectioning the upper arch and used push coil springs for canine retraction. He refined his methods and after experimenting on numerous loops, helics and wires, introduced the Rickett’s retractor in 1979. BURSTONE After the TMA wire introduced Charles. J.
