The morphology of the Prama neck has been defined as hyperbolic since the beginning due to the characteristic curvature that distinguishes it. This feature increases its capability, already inherent in the convergent shape, of adapting three-dimensionally to asymmetrical crests, with no need for augmentation or resective surgery.

Moreover the UTM surface on the neck has proven to be an excellent substrate also for osteoblasts, which lay down on it and organize themselves over time. Thereby itis possible to place the Prama implant both transgingival or submerged, depending on clinical requirements.
