Improved technique for localized ridge augmentation. A report of 21 cases

Topographical aberrations in a residual edentulous ridge often prevent establishment of a satisfactory pontic/ridge relationship. An improved technique is described for predictable augmentation of localized alveolar-ridge deficiencies. Results are reported from 21 cases involving 26 sites. All 14 sites using fibrous connective tissue grafts demonstrated shrinkage, although an improvement in residual ridge contour was obtained. Hydroxylapatite implant material was placed in 12 sites with shrinkage seen in only two sites. Advantages, requirements for success and technical considerations of the improved technique are discussed.
