Bracket removal can be painful. This study found ceramic brackets caused more pain than plastic ones, especially in anterior segments. Metal brackets required the highest removal force.
Area of Science:
- Orthodontics
- Biomaterials
- Pain Management
Background:
- Bracket debonding is associated with patient discomfort.
- Minimizing pain during orthodontic treatment is a clinical priority.
Purpose of the Study:
- To investigate the relationship between removal force and pain during orthodontic bracket debonding.
- To compare pain and force associated with ceramic, plastic, and metal brackets.
Main Methods:
- 1,235 brackets (ceramic, plastic, metal) were removed from 81 subjects.
- Pain was assessed using a visual analogue scale (VAS).
- Removal force was measured using a load cell sensor integrated with debonding pliers.
Main Results:
- Removal force was significantly lower in anterior segments compared to posterior segments.
- Pain was generally higher in anterior segments.
- Metal brackets required greater removal force than plastic or ceramic brackets.
- Ceramic brackets induced significantly more pain than plastic brackets in anterior segments.
Conclusions:
- Pain and discomfort are common during bracket debonding.
- Bracket material and location influence removal force and associated pain.
