Understanding Anterior Open Bite (AOB)
Anterior open bite (AOB) is a dental condition characterized by the lack of vertical overlap between the upper and lower incisors. This condition not only affects aesthetics but also has significant implications for speech, chewing, and overall oral function. The study conducted by de Brito Vasconcelos et al. (2020) offers valuable insights into the treatment of AOB using an extrusion arch, a fixed orthodontic device.Key Findings from the Study
The study evaluated 14 subjects with an initial mean age of 9.17 years who were treated with an extrusion arch over an average period of 7.79 months. The results were promising:- All patients achieved a positive overbite, with a mean increase of 3.07 mm.
- Maxillary incisors extruded by 1.94 mm.
- Significant retroclination of the maxillary incisors (-6.15°) and an increase in the interincisal angle (5.57°) were observed.
- There was a significant reduction in overjet (-1.65 mm), arch perimeter (-3.02 mm), and arch length (-2.23 mm).
Implications for Speech-Language Pathologists
For speech-language pathologists, these findings underscore the importance of a multidisciplinary approach to treating AOB. The extrusion arch not only corrects dental alignment but also has the potential to improve speech clarity and oral function. Here are some practical takeaways for practitioners:- Early Intervention: Early identification and treatment of AOB can prevent long-term speech and functional issues.
- Collaborative Care: Working closely with orthodontists to monitor and support the child's progress can lead to better outcomes.
- Comprehensive Assessment: Regular assessments of speech, chewing, and oral motor skills are crucial to track improvements and adjust therapy plans accordingly.
Encouraging Further Research
While the study provides robust evidence supporting the use of the extrusion arch, it also highlights the need for further research to explore long-term outcomes and potential side effects. Practitioners are encouraged to stay abreast of new findings and incorporate them into their practice to continuously improve the quality of care.Conclusion
The integration of research into clinical practice is a cornerstone of effective speech-language pathology. By applying the insights from the study on the extrusion arch, practitioners at TinyEYE can enhance therapeutic outcomes, ultimately transforming the lives of the children they serve.To read the original research paper, please follow this link: A prospective clinical trial of the effects produced by the extrusion arch in the treatment of anterior open bite.
