Abstract

Transverse maxillary insufficiency is one of the many dysmorphoses present in modern man. Since masticatory function is more affected by changes in diet and lifestyle, the stimulation of growth of the alveolar processes is weaker. The constriction of the maxilla is often the cause of dentomaxillary dysharmonia which requires space to be found on the arch. Expansion or extraction? This question has always stirred up our profession through the centuries.

However, the main part of these treatments is to obtain a stable occlusion in the long term and for this, management of the functional equilibrium is paramount. The neuromuscular environment participating in the morphogenesis of the dental arches, it is essential to take into account all these factors to potentiate the success of our treatments and to promote a harmonious.
