[A new concept for the reconstruction of the extremely atrophied mandible]

The introduction of interposition techniques for mandibular ridge augmentation brought about such great improvement in the results that we may speak, with reservations, of having achieved absolute ridge augmentation at least in the anterior mandibular area. The unsatisfactory results in the buccal area induced us to change the treatment concept and study the patients treated according to this new concept in a first post-treatment evaluation.
