Parents frequently make errors when activating rapid palatal expanders, often missing activations. This study analyzed discrepancies between prescribed and actual activations in orthodontic treatment for constricted maxillary arches.
Area of Science:
- Orthodontics
- Craniofacial Development
Background:
- Constricted maxillary arches are a common dental anomaly.
- Rapid palatal expansion (RME) is a standard orthodontic treatment.
- Accurate activation of RME devices is crucial for successful outcomes.
Purpose of the Study:
- To analyze the correlation between prescribed and reported activations in RME.
- To identify the frequency and nature of errors in RME activation protocols.
Main Methods:
- 114 subjects with constricted maxillary arches underwent RME.
- Parents received activation report forms to track prescribed activations.
- Effective activations were counted by turning back the screw upon expander removal.
Main Results:
- Errors in activation occurred in 46 out of 114 patients.
- A statistically significant correlation was found between prescribed and incorrect activations.
- Missed activations were more frequent than added activations.
Conclusions:
- Deviations from the prescribed RME activation protocol are common.
- Errors can include missed or added activations.
- Missed activations are the most frequent type of error observed.
