7. Premolar extraction treatment


The extraction treatment sequence in MEAW is as follows: 

1. Leveling and alignment 

2. Space closure stage 

a. Maxillary canine retraction, 

b. Mandibular en-masse retraction, 

c. Maxillary anterior teeth retraction,

3. Finishing 

This lecture explains criteria to be checked and precautions to be taken at each stage.


Anchorage is important for extraction treatment, and can be divided into maximum

anchorage, moderate anchorage, minimum anchorage, and absolute anchorage.


In cases of severe crowding and protruded maxillary and mandibular teeth,

it is recommended to move the maxillary and mandibular anterior teeth backward as far 

as possible.

In the majority of cases such as moderate or minimum anchorage, it is recommended to

move the maxillary and mandibular anterior teeth to aesthetically pleasing positions and

move the molars forward to close the remaining space.


Each case was highlighted in the lecture to help understand how to secure the necessary

anchorage for space closure.

In the case of premolar extraction, the mandible is likely to be positioned backward,

so evaluation and adjustment are required.

To do this, in the case of extraction treatment, an understanding of retrusive control and

elimination of occlusal force is required.


The cases of premolar extraction were divided into U44, L44 extraction, 

U44, L55 extraction, U55, L55 extraction, only U44 or U55 extraction, and asymmetric

premolar extraction, and the lectures explain differential diagnosis and indications.

In addition, through the lectures, you will be able to understand bracket selection, strategic

bonding, and accurate bracket placement to be used in each case.


In the case of extraction treatment, the occlusal plane is also important, and the

classification and tooth movement according to the normal POP and steep POP is explained.

The precautions in the small-foot calibration procedure can also be understood.
