Abstract
In the subtotally edentulous, facing the last remaining teeth, the practitioner may be faced with a dilemma: "Keep or extract". Of course the answer is not always obvious, it must take into consideration several parameters. When the practitioner decides to keep the residual teeth, he can consider, depending on the case, the implant solution, the supra-radicular prosthesis or the composite prosthesis.
 In this article we present a case of maxillary subtotal edentulism treated by the composite prosthesis. The choice of this therapy was based on a diagnostic approach leading to the manufacture of temporary prostheses that were re-evaluated over six months, then a definitive prosthesis made according to the rules of art, giving the patient a suitable smile and optimal comfort during mastication.
Highlights
Subtotal edentulism is a partial edentulism in which one to four residual teeth remain
The preservation on the arch of few and isolated dental organs presents an obvious interest, the implant option would be very relevant, insofar as it offers an alternative to the conventional total prosthesis, by bringing complementary means of retention, or the supra-radicular prosthesis [2], with or without retention means, in cases where the teeth are reduced to root stumps, in addition, composite prosthesis is possible with milled crowns with or without attachment, in some complex cases, the few saved teeth can make the therapeutic decision difficult
Endobuccal examination: Average Hygiene Saliva of normal quantity and viscous quality Plane of occlusion disturbed by the 17 eruption Sufficient vertical prosthetic space
