There are two types of orthodontic problems.

• Jaw discordance and disorders
• Dental incompatibilities (crowding, lack of space, etc.)

There are two types of jaw discrepancies.

• The lower jaw is further back (compared to the upper jaw).
• The lower jaw is more forward (compared to the upper jaw).

Cause of jaw discrepancies

• Familial (genetic)
• Developmental disorders

Types of dental disorders

• Being crowded due to lack of space
• Teeth spacing due to excess space
• Distance between the upper and lower front teeth due to thumb sucking or a larger than normal tongue
• Teeth not in their normal position

The reason for the narrowness of space (crowding)

• Genetically or developmentally, the jaw is small and the teeth are wide and therefore cannot fit into the jaw.
• When baby teeth are extracted prematurely, the remaining teeth come together and there is not enough room for the permanent tooth to emerge from underneath, causing the permanent tooth to emerge crookedly or not at all.
• Wisdom teeth crowding other teeth from behind

Reason for excess space (range)

• Genetically or developmentally, the jaw is large and the width of the teeth is narrow, so the teeth are distributed in a spaced manner in the jaw.
• Failure of some permanent teeth to emerge due to genetic or developmental reasons (in this case, the tooth is either absent or remains embedded in the jaw.)

Situations where removable orthodontic treatment is applied

• Simple level tooth misalignments
• Situations where jaw narrowness needs to be eliminated
• Preventive filling of gaps due to early milk tooth loss
• Eliminating bad habits such as thumb sucking
• Preventing teeth grinding
• For reinforcement (fixation) purposes after fixed treatment

Cases where fixed orthodontic treatment is applied

• Having crooked teeth
• There is a gap in the bite between the upper and lower teeth
• Protruding upper teeth
• The need for simple dental movements to make a better prosthesis
