Abstract

L'invention concerne une prothèse dentaire complète qui peut être produite en série avec des procédés de production simples, tout en conservant un bon niveau de qualité. Les bases de la denture (7) présentent sur leurs faces opposées des dents artificielles (3) à tenue sous la dent commandée et des espaces de correction (6) sont produits en série dans des modèles variés et une base de denture (7) correspondant de manière générale à des mesures cliniques, est intégrée dans une base muqueuse (22) sur un moulage d'étude, afin de produire un bourrelet d'occlusion classique.
