The Ability of Currently Available Stress-Breaking Elements for Osseointegrated Implants to Imitate Natural Tooth Mobility

Investigations were reviewed to show whether currently available systems (intramobile elements or specially designed suprastructures) had adequate deformability to provide osseointegrated implants with an elasticity imitating the mobility of natural teeth. While the systems tested showed variable deformability, none of them fully met the requirements. This may well explain the funnel-shaped bone resorptions seen in peri implant cortical bone.
