The non-ossified pubis

A group of syndromes is presented whose common characteristic is the absence of pubic ossification at birth with very slow posterior mineralization. This is a radiological finding of interest as it has not been described in other entities. In all the cases shown, moreover, a variable degree of delay in bone age is observed. The increase of space between the pubic bones described in these syndromes is fictious, as it really signifies the existence of non-ossified cartilage. Therefore, they must be differentiated from those which deal with real widening of the symphysis of pubis.

[A new clamp for the anchoring of partial removable prostheses]

The proposed clasp corresponds to two Ney type I clasps acting on one tooth. The two vestibular lower arms are overlapping. The clasp is applied to a cylindrical crown (like a inner telescope) or to the natural crown; it has proved a clinical succes especially in subtotal lower prostheses.
