BACKGROUND: The treatment of choice for skeletal open bite is orthognathic surgery combined with pre and post-
surgicalorthodontics; however relapse can be observed and alternative solutions are sought to avoid surgery whenever possible. A case
is reported showing an original treatment protocol in order to obtain aesthetic, functional and stable results. CASE REPORT: A 10.2
year old boy with anterior open bite was treated with a Hyrax type rapid maxillary expander on the maxilla (one month) and a lingual
arch in the lower jaw; then, grinding of deciduous molars was performed, a lingual grid was positioned and a myofunctional treatment
(exercises) was started. The subsequent treatment phase was achieved with a lip bumper and fixed straight wire appliances on both
arches. After 24 months of active treatment, retainers were used to maintain the good results achieved, which were unchanged at the
long term controls, 3 and 7 years after treatment.
