Abstract

The aim of the present study was to describe immediate functional loading of completely edentulous maxillas and mandibles by fixed provisional prostheses and to compare cumulative survival rates between maxillas and mandibles. Contributing factors including implant diameter, system, configuration, type of abutment connections, position of implants, and insertion torque values were investigated. From August 2001 to March 2007, 111 patients treated at the Associated Brånemark Osseointegration Center, Hong Kong, who received immediate functional loading of implants by fixed completely edentulous provisional prostheses were reviewed. Marginal bone changes were measured. There were 48 edentulous maxillas and 85 edentulous mandibles, in total 133 arches. Twenty-two cases received simultaneous maxillary and mandibular rehabilitation. Three hundred nineteen implants were used for the maxilla and 371 implants for the mandible, in total 690 implants. A mean of 6.65 fixtures was used to reconstruct an edentulous maxilla and a mean of 4.36 implants for an edentulous mandible. The mean follow-up period was 29.5 months, ranging from 11.5 to 71 months. Six hundred seventy-two of 690 implants (97.4%) had been followed up at least 1 year. Four ...Continue Reading
