Immediate loading of implants in the edentulous maxilla: use of an interim fixed prosthesis followed by a permanent fixed prosthesis: a 32-month prospective radiological and clinical study.
PURPOSE The aim of this study was to prospect ively evaluate the survival rate of splinted and immediately loaded Straumann s and blasted , large-grit , acid-etched , solid-screw dental implants in the edentulous maxilla after 32 months of loading . MATERIAL S AND METHODS Twenty-eight patients ( mean age 63 years ) with edentulous maxillae received 168 implants  ( six each ) and an implant-supported fixed interim prosthesis within 24 hours after surgery . After a mean healing time of 15 weeks , the patients received permanent screw-retained prostheses . Clinical and radiological examinations were made at implant placement and after 8 , 20 , and 32 months of loading . All permanent prostheses were removed at the 32-month follow-up ; implant stability was checked with a torque device , and the implant stability quotient was determined with resonance frequency analysis . RESULTS Mean marginal bone loss from baseline to 8 months after loading was 1.6 mm ( SD 1.16 ; p = .094 ) , from 8 to 20 months 0.41 mm ( SD 0.63 ; p = .094 ) , and from 20 to 32 months 0.08 mm ( SD 0.49 ; p = .039 ) . The 32-month cumulative survival rate was 98.2 % . CONCLUSIONS The 32-month survival of solid-screw implants - immediately loaded within 24 hours after placement - was similar to survival rates reported for solid-screw implants with conventional loading . Immediate loading and splinting of implants in the edentulous maxilla is a viable treatment alternative
