SUMMARY
The purpose of this case report was to describe an 11-year follow-up of a patient presenting with molar-incisor hypomineralization (MIH) having yellowish and porous permanent incisors and molars. Clinical examination revealed demarcated brown opacities on one upper and one lower central incisor and three first permanent molars. Initially, treatment involved oral hygiene and periodic fluoride varnish application. Subsequently, the occlusal surfaces of the affected molars were restored or sealed with glass ionomer cement. At-home dental bleaching was also performed. Areas of unsatisfactory esthetics on the incisors were replaced by composite resins. This report discussed the patient’s needs and expectations, the difficulties of prolonged treatment for patients with MIH, and the restorative protocol involving at-home dental bleaching and composite resins.
A new modality of orthodontic treatment based on the thermoformed appliance was developed and trialled clinically. A light-cured resilient lining material commonly used for denture relining was placed locally and sequentially in thermoformed appliances to generate orthodontic forces. The new method appeared to be effective. All the presented cases showed substantial improvement in dental alignment. A number of orthodontic movements were demonstrated. Localized use of resilient lining in thermoformed orthodontic appliances appeared to be a promising alternative to other thermoformed active removable appliance (TARA) treatments. Further studies are required to optimize the procedures and explore its full potential.
