All-on-4 concept vs. traditional implant placement methods with 25 years’ experience and over 28,000
dental implants placed

Statement of the Problem: The purpose of this lecture is to examine the incidence rate of early and late failure of dental
implants and associated prosthetic problems with reference to a total number of 28,000 implants placed during 1992-2018 in
patients requiring partial and full-arch rehabilitation.
Methodology: We have compared the nowadays popular and cost-effective all-on-4, all-on-6 rehabilitation solution with 8-10
implants placed in the maxilla and 6-8 in the mandible.
Result: Following the adaptation of various dental implant systems, our retrospective study shows that the rate of late implant
failure and the associated prosthetic problems were lower in case of increased number of implants. We suggested that the result
is due to the balanced distribution of the functional load on the implant and bone, the improved stress distribution against the
opening force of the mandible and the overload of posterior implants.
Conclusion & Significance: The benefits of the all-on-4 and all-on-6 rehabilitation solution includes that (sometimes risky)
bone grafting in the posterior mandible can be avoided, furthermore, the increased inter implant distance ensures improved
blood supply. However, excessive overloading of the implants may lead to screw fracture, prosthetic fracture and bone loss. In
case of unexpected complications, the increased number of patient visits make the cost-effective all-on-4, all-on-6 treatment
concept a subject to controversy. When comparing the risks and complications of the all-on-4, all-on-6 rehabilitation solution
with posterior mandibular bone grafting procedures, we can find similar results.
