title: Spring-loaded bite-blocks for early correction of skeletal open bite associated with thumb sucking.
abstract: Skeletal open-bite malocclusion is frequently discussed in orthodontics. Diagnosis, treatment, and retention can be difficult because this malocclusion has numerous correlated etiologic factors. The earlier this malocclusion is corrected, the better the prognosis will be, especially when the problem is skeletal. This article presents a patient with a skeletal open bite and a thumb-sucking habit who was treated in the mixed dentition with an orthodontic appliance that included an acrylic occlusal splint along with spring-loaded blocks to guide the vertical force against the posterior teeth and the alveolar process. The usefulness of the appliance as a habit-breaking therapy is also highlighted.
