Orthodontic Treatment Via Premolar Extraction
Conditions
Keywords
third molar impaction, third molar angulation, third molar vertical position
Brief summary
What is the effect of extraction orthodontic treatment in comparison to non- extraction treatment on the position, inclination and incidence of impaction of the third molars?
Detailed description
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
Interventions
PROCEDUREextraction orthodontic treatment plan
patients will be referred for extraction of the upper and lower first premolars then orthodontic treatment will follow.
