This is the first report of a group of 50 partially edentulous patients who received a total of 151 EndoporeŽ dental implants in the maxilla. A mean implant length of 8.7mm was used and 76.8% were placed in the posterior maxilla. At re-entry all implants appeared to be osseointegrated and were used to support fixed prostheses. Approximately half (57%) of the crowns in these prostheses were splinted to one another, while the remainder (43%) were not. At the time of this report the mean functional time was 34.6 months and the cumulative survival rate was 97.3% as 4 implants failed. Analysis of carefully standardized sequential radiographs indicated no significant changes in mean crestal bone levels between baseline and any of the times 6 months, 1 year and two years in function. There were no detectable correlation between crestal bone loss and any of the factors implant length (7, 9 or 12mm), implant diameter (3.5, 4.1 or 5.0mm), implant position anteriorly or posteriorly in the maxilla, or whether or not the implant-supported crowns were splinted.
