Brief Summary

1. 1.To compare maxillary canine retraction rate among conventional (labial) vs dual (simultaneous labial and palatal) force mechanics using labial fixed orthodontic appliances.
2. 2.To assess the biomechanical effects of dual force vs single force In this study we will be using the most common method i.e. labial fixed appliances with different techniques to find a more faster and controlled method of canine retraction with least undesirable movements.

Conditions

Canine Retraction

Keywords

Canine retraction; Dual force

Outcome Measures

Primary Outcomes (1)

• To compare maxillary canine retraction rate among conventional (labial) vs dual (simultaneous labial and palatal) force mechanics using labial fixed orthodontic appliances.

  Rate of canine retraction will be assessed and compared from T1 to T6 in two groups one with labial force only and the other with dual force through measurement taken on cast as well as intraorally at each timepoints through vernier calipers.

  6 months

Secondary Outcomes (1)

• . To assess the biomechanical effects of dual force vs single force

  6 months

Study Arms (2)

Labial force vs dual retraction force

EXPERIMENTAL

Rate of canine retraction was measured among labial vs dual force for retraction

Procedure: Dual force application

Dual force

EXPERIMENTAL

On one side canine retraction is done with labial force only while on other side dual force i.e labial as well as palatal forces are used

Procedure: Dual force application

Interventions

Dual force application PROCEDURE

Dual force is applied on one side and compared with conventional retraction

Also known as: Canine retraction

Dual force; Labial force vs dual retraction force
