To this study a group of 79 patients (36% male and 64% female), average age of 59 years old (ranging from 36 to 85 years old), showing atrophic maxilla, with less than 3 mm on sinus and no more than 5 mm on pre maxilla. On this group, patients presented 7 lacks of bone on maxilla 2 due to ablative surgery, 1 for previously bone graft failures, 4 due to failure of fibrous integrated implants. Associated with 185 zygomaticus fixtures, 225 conventional conic implants were installed on the anterior maxilla (ranging from 2 to 6 implants) and 11 implants were fixed on the pterigoideo bone in order to achieve better anchorage and force distributions among the implants for the prosthesis.
