Trattamento conservativo delle discrepanze dento-dentali anteriori superiori in corso di terapia ortognatodontica [Conservative treatment of upper anterior dental discrepancy during orthodontic therapy]

The orthodontic therapeutic sequence used in cases with dento-dental discrepancy for reduced mesiodistal size and congenital absent lateral upper incisors, is described. The importance of correct conoid tooth replacement in the programmed space between the other teeth and its restorative treatment in order to obtain the best biomechanical control is stressed. The contemporaneous presence of the form and volume anomaly of the 12th and the missing 22nd due to agenesia demanded an interdisciplinary approach. For the restoration of the conoid tooth the authors used a microhybrid composite for the alloy properties with the grain size of the inorganic particles. In fact this type of composite responds well to mechanical stress and has a high shining capacity and good aesthetical rendering. Meanwhile the temporary dental prothesis solution of the 22nd in this case has suggested the application of the artificial element on the superior Hawley holding plaque.
