The purpose of this study was to evaluate and modify alternative methods for implant placement in the posterior maxilla using a limited amount of existing bone, thus avoiding sinus grafting. A total of 162 patients with 343 implants in the posterior maxilla divided in 5 retrospective groups were
evaluated according to different treatment modalities: the short implants group, the palatal positioned implants group, the pterygomaxillary implants group, the tilted implants group and the implants cantilevered prostheses group. Optimal use of the posterior maxilla was achieved by modifying the surgical technique required. Patients were treated consecutively
between 2004—2011, and were followed up 60 months after prostheses delivery. A success rate of 96.7% for short implants, 93% for palatal positioned implants, 92% for pterygomaxillary implants, 94.6% for tilted implants and 95.2% for implants with cantilevered prostheses at 5 years of follow up was obtained. No statistically significant differences were found between the groups for either of the evaluated procedures. Placing implants in preexisting bone in the posterior maxilla enables avoidance of more complex surgical procedures such as sinus floor augmentation. These methods led
to simpler, more predictable, less expensive, and less time-consuming treatment compared to more invasive maxillary sinus augmentation.
