🔴Serial extraction🔴
correctly timed removal of certain deciduous and permanent teeth in mixed dentition cases with dentoalveolar disproportion in order to alleviate crowding of incisor teeth; allow unerupted teeth to guide themselves into improved positions.

🔴PRINCIPLES OF SERIAL EXTRACTION🔴
The treatment objective for a serial extraction is to intercept an arch length deficiency problem to reduce or eliminate the need for extensive appliance therapy.

🔴INDICATIONS🔴
• Premature loss of deciduous teeth
• Arch length deficiency and tooth size discrepancy
• Absence of physiologic spacing
• Lingual eruption of lateral incisors
• Unilateral deciduous canine loss and midline shifting
• Premature loss of deciduous teeth
• Arch length deficiency and tooth size discrepancy
• Absence of physiologic spacing

• Unilateral deciduous canine loss and midline shifting
• Canines erupting mesial to the lateral incisors
• Mesial drift of buccal segment
• Abnormal eruption direction and eruption sequence
• Gingival recession on labially displaced incisors
• Flaring, ectopic eruption, ankylosis, etc.

🔴Advantages🔴
🔹 Psychological trauma can be avoided.
🔹 Reduces the duration of the multi banded treatment.
🔹 Physiological treatment because it involves the guidance of teeth into normal positions making use of physiological forces.
🔹 Better oral hygiene.

🔴 Disadvantages 🔴
🔹 Long term procedure that requires thorough knowledge of growth, development, eruption sequence and calcification of permanent teeth.
🔹 Prolonged treatment time with multiple visits (2 – 3years).
🔹 Patient cooperation is very important.

🔹 Possibility of developing tongue thrust.
🔹 Tendency to increase over bite (deepening of the bite).
🔹 Residual spaces can remain between the canine and second premolar.
🔹 Subjecting the child to multiple progressive extraction visits.
