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

Study Groups

Piezocision on Experimental Side A

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

Group Type: EXPERIMENTAL

Piezocision

Intervention Type: PROCEDURE

Piezocisions with the help of piezotome , mesial and distal to a canine (in a vertical line) with the help of piezotome. These piezocisions will be performed on the buccal cortical bone only, 2-3mm below the alveolar crest level, 2mm deep into the bone under local anaesthesia (2% lidocaine with 1:100,000 epinephrine) and with standard asepsis, and gingival overlying will be incised first with blade number 15 in a Bard Parker handle . The exact location of incision will be determined by transgingival probing mesial and distal to the canine to know the alveolar crest level and to this measurement 2-3 mm is added and then 5mm incision is given in gingiva and overlying mucoperiosteum in a vertical line apically to expose the underlying bone.

Micro-osteoperforations on Experimental side B

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

Group Type: EXPERIMENTAL

Micro-osteoperforations

Intervention Type: PROCEDURE

Three MOPs mesial and three MOPs distal to canine(in a vertical line) with the help of minisrew implant driver (fig.2). These MOPs will be performed on the buccal cortical bone only, 2-3 mm below the alveolar crest level, 2mm deep into the bone under local anaesthesia (2% lidocaine with 1:100,000 epinephrine) and with standard asepsis, and no flap will be raised. The exact location of first MOP will be determined by transgingival probing mesial and distal to the canine to know the alveolar crest level and to this measurement 2-3 mm is added. The location of second MOP at 5mm apically in a vertical line and third MOP at 5 mm apically to second MOP
