Quality of orthodontic treatment with straightwire or standard edgewise appliances
- Conditions
- Most orthodontic malocclusions can be effectively treated with comprehensive fixed appliance treatment, due to the ability of the latter to perform controlled tooth movements in all three planes of space. Often, severe arch length discrepancies or several dental/skeletal malocclusions necessitate the incorporation of dental extractions in the orthodontic treatment plan.Oral Health
