Molar-incisor hypomineralization is a qualitative deviation that compromises the enamel hardness, and thus predisposes the affected tooth to mechanical breakdown that may endamage the pulp and the longevity of the impacted teeth. Besides the functional and aesthetic problems brought on by the structural involvement of the enamel, there are also behavioural and psychological consequences for patients. Since their childhood, the patients’ behaviour should be closely monitored to effectively manage the situation before it worsens. Various potential approaches to treat MIH-affected teeth exist, few are yet supported by good-quality clinical research data. It has become increasingly apparent that the conservation of tooth structure is a significant factor in determining the long-term prognosis of any restorative procedure. Thanks to the progress in bonding techniques, porcelain aesthetics, and mechanical properties, different alternatives are now possible in order to treat affected teeth while being the least invasive. The present clinical case report shows an aesthetic rehabilitation of posterior teeth with molarincisor hypomineralization using an overlay and a veneerlay.
