Summary
Early correction of skeletal open bite malocclusion in mixed dentition is crucial. This study shows an effective orthodontic appliance for guiding vertical forces to improve prognosis.
Area of Science:
- Orthodontics
- Dentofacial Orthopedics
Background:
- Open bite malocclusion presents diagnostic and treatment challenges due to multifactorial etiology.
- Skeletal open bite malocclusion requires early intervention for optimal treatment outcomes.
Observation:
- A patient with skeletal open bite malocclusion in the mixed dentition stage was treated.
- The treatment utilized an orthodontic appliance adapted from the Thurow appliance.
Findings:
- The appliance incorporated an acrylic occlusal splint and an expansion screw.
- This design aimed to direct vertical forces onto the posterior teeth and alveolar process.
Implications:
- This approach offers a method for managing skeletal open bite during the mixed dentition phase.
- Early and guided vertical force application may improve treatment prognosis for open bite malocclusion.
