Conditions

Health Condition 1: M263- Anomalies of tooth position of fully erupted tooth or teeth Health Condition 2: K088- Other specified disorders of teethand supporting structures

Interventions

Intervention1: V bend mechanics: Mesialization of mandibular molar on 019 X 025 inch SS archwire. V bend will be placed in gingival direction distal to the bracket of tooth mesial to extraction space.

Eligibility

Inclusion criteria

Inclusion criteria: 1) Age greater than 14 years. 2) Mandibular second premolar or first molar extraction cases. 3) Missing mandibular second premolar with/without retained deciduous second molars. 4) No signs of spontaneous mesial posterior tooth movement due to exfoliation of the deciduous second molar on the agenesis site. 5) Treatment plan should include mandibular molar mesialization of 4mm or more. 6) Healthy periodontium at the start of the treatment. 7) No tooth size arch length discrepancy.

Exclusion criteria

Exclusion criteria: 1) Missing or extracted mandibular second molars. 2) Grossly decayed mandibular second molars. 3) Patients who had received prosthetic treatment for the missing teeth. 4) History of previous orthodontic treatment. 5) Patients with systemic diseases, cleft lip and palate and other craniofacial abnormalities 6) Patient who is undertaking treatment for any disease or under medication which can affect tooth movement.

Design outcomes

Primary

Measure	Time frame
Rate of mandibular molar mesialization using V-Bend mechanicsTimepoint: T0- At the initiation of molar mesialization T1- At the end of molar mesialization after space closure	—

Secondary

Measure	Time frame
1. To assess success rate of mandibular molar mesialization using V-Bend mechanics. 2. To assess the anchorage loss in the anterior segment after completion of mandibular molar mesialization. 3. To assess change in angulation of mandibular premolar & first or second molar after completion of mandibular molar mesialization. 4. To assess alveolar bone height & thickness after completion mandibular molar mesialization. 5. To assess the amount of external apical root resorption in mandibular first or second molars after mandibular molar mesialization. Timepoint: T0- At the initiation of molar mesialization T1- At the end of molar mesialization after space closure	—
