Neuromuscular environment and stability of transverse maxillary expansion

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.
