Study type | Interventional |
Brief summary: there's a scarcity in literature concerning time needed to retract anterior segment following premolars extraction. the purpose of this study is to determine, in orthodontic patients with maxillary protrusion, which form of technique of retraction offers a faster treatment duration of retraction : en-masse or two step techniques

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Time to close extraction space | the antero-posterior movement of anterior teeth are assessed by monthly taken models and patient record sheets | from pre to post retraction ( an average of 10 - 12 months) | |
Secondary | Anchorage loss | Digitalized dental models taken before and after completion of retraction will be measured by identifying landmarks and reference lines and planes ( measured in mm) | From pre to post retraction ( an average of 10- 12 months) | |
Secondary | pain of intervention | Each patient was informed to fill a questionnaire regarding treatment experience in Visual analogue scale scoring from (0 -10) 0 means no pain and 10 means severe pain | From pre to post retraction ( an average of 10 - 12 months) |
