Summary
This study provides scientific evidence for orthodontic treatment mechanics using pre-adjusted edgewise appliances. Findings support archwire selection, canine lacebacks, and space closure methods for fixed appliance therapy.
Area of Science:
- Orthodontics
- Dental Mechanics
- Evidence-Based Dentistry
Background:
- The pre-adjusted edgewise appliance is a common orthodontic tool.
- Establishing a scientific basis for treatment mechanics is crucial for effective clinical practice.
Purpose of the Study:
- To present scientific evidence supporting treatment mechanics in orthodontics.
- To review findings from clinical trials on the pre-adjusted edgewise appliance.
Main Methods:
- Conducted a literature search of Medline and the Cochrane Clinical Trials Register (CCTR).
- Included randomized and controlled clinical trials published from 1970 to June 2005.
Main Results:
- Evidence supports specific archwire choices for orthodontic treatment.
- The use of canine lacebacks is supported by clinical evidence.
- Methods for space closure in fixed appliance therapy have a scientific basis.
Conclusions:
- This review provides a foundation for evidence-based management of fixed appliance mechanics.
- Scientific evidence supports key aspects of pre-adjusted edgewise appliance therapy.
