TITLE OF STUDY: “Accelerating Orthodontic Treatment with Micro-osteoperforation Assisted Traction of Maxillary Impacted Canine: In-vivo Study”

INVESTIGATOR: Dr SHAFNA V

CO-INVESTIGATOR: DR RAM K RATRE

INTRODUCTION- Micro-osteoperforation involves the creation of tiny perforations in the cortical bone surrounding the impacted tooth, utilizing minimally invasive procedures. These perforations stimulate localized bone remodeling, facilitating the movement of the impacted canine towards its desired position

AIMS :

To evaluate and compare the effectiveness of accelerating orthodontic treatment with micro osteoperforation- assisted traction of maxillary impacted canines with traditional method

OBJECTIVES:

1. To assess the traction duration and compare the traction duration in traditional traction group(TT) & micro osteoperforation assisted traction group(MAT)
2. To assess the velocity of traction movement, determined by divding the depth of impaction,which is defined as the distance from the impacted canine cusp tip to the occlusal plane,by the traction duration

METHODOLOGY

SAMPLE SIZE:30 patients,  GROUP I-Traditional traction group(TT)-15 patients

                        GROUP II- micro osteoperforation assisted traction group(MAT)- 15 patients

INCLUSION CRITERIA

1. Patients aged 15-30 years
2. Maxillary impacted canines with less than 45-degree angle between the canine’s longitudinal axis and the vertical facial plane.

EXCLUSION CRITERIA

1. More than 45-degree angle between the canine’s longitudinal axis and the vertical facial plane

2. Presence of contact between the canine crown and the lateral incisor root

3. Previous orthodontic treatment

4. Any medical condition that prevents oral surgery

PROCEDURE: 30 patients will be selected randomly and then will be divided into two groups. 15 patients will be assigned to conventional treatment group and 15 will be assigned to micro osteoperforation assisted traction  group.

The aligning and leveling of the maxillary dental arch will be performed using the fixed orthodontic appliance and will create sufficient space for aligning the impacted canine within the dental arch. In both study groups, the impacted canines will be surgically exposed using the closed flap approaches.

 MOPs will be performed under local anesthesia using IDO device for micro osteoperforation with FavAnchor straight hand driver. 2 MOPs will be placed where the impacted canine would be moved towards as well as, 2  each in mesial and distal sides of the canine crown . Each perforation will be 1.2 mm wide ,3 mm deep and 2mm apart from each other. An attachment with ligature wire will be bonded to the exposed canine crown .

Follow-up orthodontic procedures: The traction force will be applied by tieing the ligature wire to the arch wire .The intensity of the applied traction force will be 60g measured using intraoral force guage.  Re-activation will be done every 2 weeks until the appearance of half of the clinical crown of the impacted canine, this moment will be considered as the end of the active traction phase

STATISTICAL ANALYSIS: Statistical analysis will be done using an independent sample‘t’ test between-group comparison and within the group using paired‘t’ tests.
