Spring-loaded bite-blocks for early correction of skeletal open bite associated with thumb sucking
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…
In-office distance learning for practitioners
Introduction Distance learning studies involving orthodontic residents have shown that, although residents prefer being live and interactive with an instructor, they learn almost as much from watching a recorded interactive…
