THE LONGITUDINAL CLINICAL EFFECTIVENESS OF OSSEOINTEGRATED DENTAL IMPLANTS - THE TORONTO STUDY .3. - PROBLEMS AND COMPLICATIONS ENCOUNTERED

Two hundred seventy-four implants were placed in 49 dental arches of 46 consecutively treated patients. The success rate for individual implants in this study, 4 to 9 years after placement, was 89.05% and for the prosthetic treatment it was 100%. Problems and complications were observed and recorded at stage I surgery, between stage I and stage II surgery, at stage II surgery, and in the healing period that followed. Also noted were the complications subsequent to prosthodontic treatment and during the years of follow-up. Virtually all of the problems encountered were iatrogenic in nature. These clinical results indicate a safe and retrievable technique with negligible associated morbidity. © 1990 Mosby-Year Book, Inc.
