Efficiency of Microosteoperforation for Accelerating Posterior Segment Intrusion in Skeletal Open Bite Cases

Egypt30 participantsStarted 2015-04-22

Plain-language summary

This clinical trial aimed to assess the efficiency of micro-osteoperforation for accelerating posterior intrusion in open bite cases. A human sample of thirty subjects was divided into two groups ; Group I (MOP), posterior intrusion with micro-osteoperforation (MOP) and group II (Control), same intrusion protocol without micro-osteoperforation.

Inclusion Criteria: * Clinical anterior open bite involving the incisors and canines ranging from -3 mm to -8 mm * Skeletal open bite confirmed by pretreatment cephalometric angular and linear measurements. * Maxillary posterior vertical dentoalveolar excess guided by the analysis of Burstone et al. * Normal incisor display at rest and during smile. * Non-growing postpubertal adolescent and adult patients with CVM 6 according to Baccetti et al. * Full set of permanent dentition regardless of third molars. * Good oral hygiene. Exclusion Criteria: * Skeletal Class III cases. * Patients suffering from any systemic diseases or congenital anomalies affecting bone. * Patients with previous orthodontic treatment.

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.

What they're measuring

Rate of maxillary posterior segment intrusion (mm/4 weeks)

Timeframe: Study models were obtained every four weeks from baseline until a positive overbite was obtained at an average of 6-9 months .

Skeletal, dentoalveolar and soft tissue changes

Timeframe: Patients were subjected to posterior segment intrusion forces until a positive overbite (+1-2 mm) was obtained at an average of 6-9 months

Evaluation of TMJ changes

Timeframe: From beginning of intrusion till a positive overbite was observed at an average of 6-9 months

Total amount of posterior intrusion (mm)

Timeframe: From beginning of intrusion till a positive overbite was observed at an average of 6-9 months

Air way changes in volume after intrusion

Timeframe: From beginning of intrusion till a positive overbite was observed at an average of 6-9 months

Changes in alveolar bone density after posterior intrusion

Timeframe: From beginning of intrusion till a positive overbite was observed at an average of 6-9 months
