Appointment Intervals and Orthodontic Tooth Movement

A Randomized Clinical Trial Investigating the Effect of Appointment Intervals on Orthodontic Tooth Alignment

• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 46 (estimated)
• Sponsor: Guy's and St Thomas' NHS Foundation Trust · Academic / Other
• Sex: All
• Age: 12 Years – 18 Years
• Healthy volunteers: Not accepted

Summary

The purpose of this study is to investigate rapidity of tooth alignment in a randomised clinical trial of orthodontic patients allocated randomly into two different appointment intervals groups. First group will be reviewed every two weeks to adjust their braces while the second group will be reviewed every 8 weeks.

Detailed description

Orthodontics is a branch of dentistry concerned primarily with the correction of dental crowding or tooth malalignment. The first phase of fixed appliance orthodontic treatment is concerned with tooth alignment and relies upon a rapid and predictable response of the appliance system to the forces applied by the aligning archwire. The appropriate length of time between orthodontic appointments, generally called the 'appointment interval', has been the subject of debate for many years. Doctors all have their own preferences, based either on what they were taught in their orthodontic specialty programs or on community norms. Little evidence has been presented in the orthodontic literature to support these biases. The appointment interval may influence tooth alignment rates and treatment time along with other variables, such as periodontal status. Accelerating orthodontic tooth movement can significantly reduce treatment duration and the risk of side-effects.

Conditions

• Orthodontic Treatment

Interventions

Type	Name	Description
OTHER	appointment interval	To change the appointment interval for one group and keep the standard interval for the other group by measuring alignment duration, measured as days needed to align the teeth using full-arch fixed appliances
