REPORT OF 302 CONSECUTIVE RIDGE AUGMENTATION PROCEDURES - TECHNICAL CONSIDERATIONS AND CLINICAL-RESULTS

Three hundred two consecutive ridge augmentation procedures (289 in a buccolingual and 13 in an apico-occlusal direction) were performed in 284 patients. Gore-Tell membranes of various configurations were used in conjunction with various nonautogenous particulate materials. Two h undred ninety-one of the augmented ridges (279 buccolingual and 12 api co-occlusal augmentations) demonstrated sufficient regenerated hard ti ssues for implant placement in ideal prosthetic positions. This repres ents an overall ''success'' rate of 96%, 97% for horizontally augmente d ridges and 92% for vertically augmented ridges. A total of 574 impla nts were placed in the augmented ridges; 346 of these implants have su bsequently been uncovered and restored. Seven implants failed to achie ve osseointegration, and three implants (in one patient) were lost in function, for an overall survival rate of 97% for the uncovered implan ts.
