title: Localised maxillary ridge expansion with simultaneous implant placement: a case series.
abstract: The placement of implants in edentulous areas is often compromised by a thin alveolar crest, which widens the space between the two cortical bones; this offers advantages from aesthetic, biomechanical, and functional points of view. We present our results using the osteotome technique for the creation of a site for an implant, followed by immediate placement of the implant in thin edentulous maxillae, and the stability of the bony expansion over time. Twenty-three patients (six men and seventeen women) with partial edentulism associated with horizontal resorption of the ridges were treated by this technique to obtain a wider bony base for better placement of the implants. At the same time, 36 endosseous titanium implants were inserted. Three to four months later, the patients were rehabilitated with implant-supported prostheses. All implants were successfully osseointegrated and loading began after 61-197 days. All implants inserted were 4.1 mm in diameter, and between 10 and 15 mm long. All the implant-supported prostheses functioned acceptably, with no signs or symptoms such as paraesthesiae, dysaesthesiae, or pain. Within the limits of this study this technique seems to be reliable and simple with little morbidity, and rehabilitation was as good as that after other techniques such as autogenous bone grafts or guided bone regeneration. Survival and the success of implants placed were consistent with those placed in non-reconstructed bone.
