[Primary sulcoplasty with hydroxylapatite augmentation for extreme ridge resorption]

Hydroxylapatite is commonly used for augmentation of the atrophic alveolar ridge. A new surgical technique is described for HA-augmentation and simultaneous vestibuloplasty on the severely atrophic jaw. The open surgical technique includes a lingually based mucoperiostal flap, the implantation of Hydroxylapatite particles in a vicryl mesh and the use of a positioning splint. First results show a sufficient depth of the vestibular sulcus and only few complications (circumscripted mucosal erosions). No lateral or lingual dislocation of the implanted HA-particles and no permanent mental nerve anaesthesia were observed. The prosthodontic results show increased stability and retention of the dentures following the one stage surgery.
