BACKGROUND: Recent reports have demonstrated that immediate/early loading of dental implants is a clinically feasible concept with results similar to those for two-stage procedures, at least in good bone qualities. However, documentation of the outcome of immediate/early loading in the totally edentulous maxilla is scarce. PURPOSE: The present investigation was undertaken to evaluate the outcome over 1 year of oxidized @entity702 implants when loaded with a fixed full-arch bridge in the maxilla 1 to 9 days after implant placement. MATERIALS AND METHODS: Ten @entity1 with totally edentulous maxillas were treated with 61 oxidized @entity702 implants, and a provisional fixed bridge was delivered after 1 to 9 days (mean 2.5 d). Nine @entity1 had six implants and one @entity1 had eight implants supporting the bridge. The provisional bridge was replaced with a permanent bridge after 2 to 7 months (mean 4.1 mo) of loading. Resonance frequency analysis (RFA) for implant stability measurements was made at implant placement in eight @entity1 and in conjunction with permanent bridge connection in five @entity1 . The @entity1 were followed up for 1 year with clinical and radiographic examinations. RESULTS: Four implants (6.6%) were lost in one @entity1 after 10 weeks of loading owing to an @entity281 . All other implants were clinically stable with a mean marginal @entity604 .3 +/- 0.6 mm after 1 year of loading. RFA showed a mean primary stability of 60.1 +/- 3.6 ISQ (implant stability quotient), which increased to 62.8 +/- 1.6 ISQ after, on average, 4 months. CONCLUSIONS: The results from this limited study on 10 cases indicate that early loading protocols can be applied for cross-arch dental bridges supported by six to eight implants in the maxilla. However, more clinical trials are needed to establish the long-term predictability of the treatment.
