ABSTRACT
Dental erosion is a high prevalence condition characterized by the loss of dental substance due to chemical agents. it can also be associated with physical wear, affecting function and aesthetics. ceramic veneers can provide effective solutions to patients affected by erosive disorders, by means of an indirect approach and minimal intervention. recent advances in cementation techniques and ceramic materials have allowed their use in reduced thicknesses, known as "dental contact lenses" or "ultra-thin veneers". they contribute significantly to the preservation of the dental structures, having excellent mechanical properties and providing satisfactory aesthetic solutions. their manufacture requires rigorous planning and the use of three-dimensional models or mock ups in order to preview the final outcome. case: the aim of this report is to communicate the use of this technique for the treatment and successful 12-months follow-up of a patient affected by dental erosion of the maxillary central incisors. special interest was placed on direct mock-up, which is a simple technique not requiring laboratory steps. luting of the lithium disilicate veneers was carried out with a light-curing resin cement and try-in pastes, yielding a very satisfactory result. conclusion: diagnosis and early treatment of this disorder allows the application of conservative techniques, such as ultra-thin veneers, which are seen as a promising alternative treatment to full coverage restorations and traditional ceramic veneers.

La displasia ectodérmica pertenece a un grupo heterogéneo de trastornos congénitos. La más frecuente es la displasia ectodérmica hipoidrótica, hipotricosis y alteraciones dentarias. La disminución de la cantidad de piezas dentarias, al igual que las anomalías en la forma de las mismas(dientes conoides), son relevantes para el diagnóstico y tratamiento odontológico. La reheabilitación debería comenzar a edades tempranas, alrededor de los 3 años. Consiste en reponer las piezas dentarias ausentes con prótesis de acrílico, las cuales deben renovarse periódicamente. De esta manera, se logra aumenttar la dimensión vertical, regular las funciones foniátricas y masticatorias, mejorando así la dicción y la autoestima de los pacientes. Para ello, de fundamental importancia el rol del dentista pediatra en el manejo interdisciplinario del niño afectado. Cuando finalice la etapa de crecimiento, se optará por el tratamiento definitivo más adecuado.
Ectodermal dysplasia is a heterogeneous group of congenital disorders. Hypohidrotic ectodermal dysplasia is the most common type. It is characterized by the triad of signs comprising hypohidrosis, hypotrichosis and dental abnormalities. The lack of teeth and conical or pointed teeth are important for diagnosis and clinical management. Treatment should be started as soon as possible. Early placement of partial or full dentures is commonly recommended from the age of three years. Removable protheses must be periodically modified. Prosthodontic rehabilitation is fundamental in these situations, attempting to provide a functional and aesthetic solution and to control the vertical dimension, which will improve patients diction and self-steem. For these reasons it is important to consider the role of the paediatric dentist in interdisciplinary management of the affected child patient. At the time the patient finishes growing, the possibility of definite treatment should be considered.
