Bone marrow content measured in radioimmune bone marrow scintigraphy: intra- and inter-observer variability.

The aim of this study was to assess the possible quantification of vertebral residual bone marrow content relative to the bone marrow content of a non-irradiated vertebra. This method is based on the vertebral count activity, measured using radioimmune bone marrow scintigraphy. First, however, we had to evaluate intra- and inter-observer variability.

After detailed examination of most products used for rehabilitation of atrophied alveolar borders, the authors describe the procedure of surgical use of hydroxylapatite blocks placed under periosteum. In a further stage, this method can be completed by a vestibuloplasty combined with a depression of the floor covered and protected by a graft.
