Comparative Assessment of Maxillary Canine Retraction With and Without Piezocision

Pakistan30 participantsStarted 2022-07-01

Plain-language summary

Intraoral impressions with alginate will be taken at the start of treatment and plaster casts will be obtained by using ortho plaster. Separators will be passed mesial and distal to first molars to create space for band placement. After 7-10 days bands will be cemented on first molars. Pre- adjusted edgewise brackets with 0.022 in-slot Roth appliance will be bonded on teeth according to the treatment plan. Extractions will be done according to the treatment plan and piezocision will be carried out after levelling and alignment. This will be a split mouth study with one side receiving piezocision (experimental) and the other side acting as control, after random allocation. Randomization will be done by simple randomization method in which experimental side will be randomly allocated to the patient and opposite side of the same patient will act as control. First patient will have piezocision on right side and 2nd patient will have piezocision on left side, 3rd patient will have piezocision on right side and 4th patient will have piezocision on left side and so on. After extraction of maxillary first premolars, piezocision will be performed on experimental side whereas the opposite side will be taken as control. Piezocision will be performed under local anesthesia by giving two vertical interproximal incisions on mesiobuccal \& distobuccal line angles of canine on experimental side 2mm below the interdental papilla with piezo electrical knife without flap reflection. Piezoelectric incisions of the cortical alveolar bone will then be made with piezotome. The incisions will be sutured with non resorbable 4-0 black silk with the interrupted suture technique. After piezocision canine retraction will be carried out by either continuous mechanics, sectional mechanics or sliding mechanics depending on the treatment plan. Mechanics will be same on left and right side of the patient and mean retraction will be measured at four time intervals. T0 at the start of canine retraction, T1 at 4 weeks, T2 at 8 weeks and T3 at 12 weeks after piezocision

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
