Results: Success rates of surgical procedures ranged from 60% to 100% for GBR, from 92%
to 100% for onlay bone grafts, from 98% to 100% for ridge expansion techniques, from
96,7% to 100% for DO, and was 87.5% for revascularized flaps, whereas survival rates of
implants ranged from 92% to 100% for GBR, from 60% to 100% for onlay bone grafts, from
91% to 97.3% for RE, from 90.4% to 100% for DO, and, finally, was 88.2% for
revascularized flaps.
Conclusion: On the basis of available data it was shown that it was difficult to demonstrate
that a particular surgical procedure offered better outcome as compared to another. The
main limit encountered in this review has been the overall poor methodological quality of
the published articles. Therefore larger well-designed long term trials are needed.
