Teeth, in the general phenomenon of growth contribute to the blooming and the growth of the young child. It plays a paramount role in the communication while taking part in the development of the language and of the phonation, and by perfecting the shape of the face. The prosthetic rehabilitations are addressed to children who present more or less significant early losses of teeth, whose origin could be congenital, structural, post-decays or traumatic, and bearing on temporary, mixed or final teeth. The series of case presented clarifies the methods which we employ in our service for the design and the practical realization of the prosthetic rehabilitations. The dental lose seriously disturbs the physical development of the child, it can slow down its school development and affect in a pathological way its relational life. The installation of prosthesis makes it possible to the child to feel like the others, to eat normally, to better sleep, to be able to present its face without causing mocking remarks. Among our patients candidates with the prosthetic rehabilitation, the children in low-age are most numerous and present the highest frequency of the traumatisms. Their first real smile is already the justification of the decision of the specialist. Nevertheless, the number of toothless children who profit from this type of rehabilitation is very small.
