Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Data regarding the personal information (name, age and gender), chief complaint, medical and dental history will be taken. Medical history questionnaire will be filled by the patient to exclude the presence of any systemic conditions.

complete set of orthodontic records will be taken; Pre- operative records including (standardized intra- and extra-oral photographs, primary impression for study model, panoramic \& lateral cephalogram). After formulating the best treatment plan for each patient, All patients will be enrolled into one of two groups: Intervention Group (I) : Extraction treatment group. Comparator group (C): Non-extraction group. Following the end of treatment, Post-treatment records including (standardized intra- and extra-oral photographs, primary impression for study model, panoramic \& lateral cephalogram) will be taken.

Primary outcome: The angulation of the mandibular third molars.Secondary outcomes:

1. space available for the upper and lower third molar.
2. Angulation of the third molar.
3. The vertical position of the third molars.
4. the mineralization status of the third molars

extraction treatment

patients will be referred for extraction of the upper and lower first premolars to relieve the crowding.

Group Type ACTIVE_COMPARATOR

extraction orthodontic treatment plan

Intervention Type PROCEDURE

patients will be referred for extraction of the upper and lower first premolars then orthodontic treatment will follow.

non-extraction treatment

Leveling and alignment of the moderate crowding will be performed through a recall visits of 4 weeks for wire activation. inter-proximal reduction step might be done if needed.
