Self-ligation in the year 2000, a comparative assessment of conventional ligation and self-ligation bracket systems Objective
Berger J. Journal of Clinical Orthodontics 2000.
A retrospective assessment of clinical studies relating to the effectiveness and efficiencies of self-ligating brackets as compared with conventionally ligated straightwire appliances.
Methodology
More than twenty published articles/clinical studies were analyzed.
Findings
- Self-ligating brackets were found to provide greater patient comfort, shorter treatment time, reduced chairtime and more precise control of tooth translation.
- Self-ligating brackets demonstrate dramatically less friction. Such reduction in friction can help shorten overall treatment time, especially in extraction cases.
- The authors of several studies reported an average of four months' reduction in treatment time and a significant savings of chairtime in changing archwires.
- Self-ligation reduces the risks of percutaneous injury. It also protects the patient from soft-tissue lacerations and possible infections from the cut ends of steel ligatures.
- Elastomeric ligatures not only show a rapid rate of decay and deformation, but they are often associated with poor oral hygiene. With the elimination of ligatures, self-ligating appliances can significantly improve the hygiene of all patients.
Conclusion
"As more orthodontic practices embrace the concept of self-ligation, it is becoming apparent that stainless steel and elastomeric ligatures will eventually be as outdated as full banding is today. Considering the advantages of self-ligating brackets for the clinician, staff, and patient, they (self-ligating appliances) may well become the 'conventional' appliance systems of the 21st century."
