Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Many types of bonded retainers with different properties could be bonded, each with different effects on periodontal health, potentially a different ability to maintain alignment, and different amounts of failure.
Different types of failure of fixed bonded retainers are possible. When the retainer does not stay in place and is debonded, this is is described as failure. It is also possible the retainer maintains bonded but shows unwanted tooth movement in the bonded teeth. This can also be described as a failure.
Bonding of the retention wire is a technique sensitive process. Correct and passive bonding could prevent debonding of the retainers. To eliminate moisture in the bonding process, it is possible to place a rubberdam before bonding the retainer.
One aim of this study is to compare two types of bonded retainer: the standard coaxial or twisted retainer. The other aim is to compare two bonding protocols with and without rubberdam isolation
Two general PICO questions can be formulated:
In an orthodontic patient (P), will fixed retention with a Ortho-flextech tm (Reliance orthodontic products, Itasca III, USA) (I) as compared to a 0.0195 in dead-soft coaxial wire (Respond; Ormco, Orange, Calif). (C) result in a more effective or efficient retention treatment (O)?
In an orthodontic patient (P), will placement of the retainer with rubber dam (I) result in less debonding (O) as compared to relative isolation with cotton rolls (C)?
Efficiency: is the procedure faster or cheaper than the alternative? Effectiveness: is the procedure better in maintaining the end result of treatment than the alternative? Are there less biomechanical or biological side effects?
