Finite element studies have shown that occlusal load is concentrated at the implant-marginal bone interface.23,24 Consequently, occlusal loading is an important aspect of prosthetic design, since dental implants do not have a periodontal ligament to adjust to varying loads and they are less resistant to load variations than natural teeth. A systematic review of the literature concluded that in the presence of poor oral hygiene, occlusal overload leads to peri-implant bone loss.25
