"Effects of Piezocision vs Micro-osteoperforations on the Rate of Maxillary Canine Retraction

Not Applicable

• Conditions: Angle Class II, Division 1 Malocclusion
• Interventions: Procedure: Piezocision; Procedure: Micro-osteoperforations

• Registration Number: NCT04743700
• Lead Sponsor: Postgraduate Institute of Dental Sciences Rohtak

Brief Summary

Acceleration of orthodontic tooth movement persuades tremendous rise in the interest of adolescents and aduts, as it not only shortens the treatment duration but also lessens the incidence of white spot lesions, root resorption, periodontal and other soft tissue problems. Minimal invasive techniques i.e.both piezocision and micro-osteoperforations had promising results in accelerating tooth movement. Therefore current study will provide evidence for better minimal invasive technique in terms of reducing treatment time and patient comfort.

Detailed Description

Patients with Angle's Class II division 1 malocclusion meeting selection criteria and are indicated for maxillary first premolar extraction, patients will be referred for extraction of the maxillary first premolars , treatment will be initiated by bonding preadjusted MBT 0.022" slot straight wire appliance(Patient will be instructed to report immediately in case of breakage of appliance), after that, leveling and alignment will be done in all subjects, after insertion of 0.019"× 0.025" stainless steel arch wire, alginate impression and periapical radiograph of canine and first molar region will be taken(Before the initiation of canine retraction), randomisation and allocation of two sides of maxillary arch i.e. right and left will be done and active interventions(piezocision and micro-osteoperforations) for each side will be done, immediately maxillary canine retraction will be started with mini-implant and closed NiTi coil spring, patient will be asked to fill pain and discomfort assessment card immediately after initiation of canine retraction., subsequent impressions records will be taken at 4th, 8th, 12th and 16th weeks for measuring rate of maxillary canine retraction, data collection and interpretation of results, further pain assessment cards will be filled after 24 hours, on 7th day and 28th day

Arm && Interventions

Group	Intervention	Description
Piezocision on Experimental Side A	Piezocision	Piezocisions with the help of piezotome , mesial and distal to a canine (in a vertical line) with the help of piezotome to accelerate maxillary canine retraction
Micro-osteoperforations on Experimental side B	Micro-osteoperforations	Three MOPs with the help of mini-implant screw driver,mesial and distal to canine(in a vertical line) with the help of minisrew implant driver to accelrate maxillary canine retraction

Primary Outcome Measures

Name	Time	Method
Measurement of rate of canine retraction	16th week	Distal movement of maxillary canine is measured in mm with the help of electric digital caliper or acrylic plug method after beginning of maxillary canine retraction

Secondary Outcome Measures

Name	Time	Method
Assessment of pain/discomfort level	28th day	The participants will be asked to assess their level of discomfort on the day of initiation of canine retraction with visual analog scale(VAS).
