In Vivo Observations of Dental Implant Bone Bed Correlated to Stress Distribution Models
Original language description
Chewing grinding forces act mostly in vestibulo-oral and disto-mesial directions and cause implants leverage, thus leading to overloading of their bone bed. It may impair the osseointegration and thus shorten the implant functional life. In this study, mathematical models of stress distributed around loaded cylindrical dental implants were compared with changes at implant bone bed level observed in vivo. The stress computations were made by the finite-element method using simplified 3D models of the implant and the bone bed. Changes of implant bone bed were followed in 45 patients in different intervals after their insertion and loading using morphometric analysis of RVG pictures taken every 6 months. The mathematical analysis showed maximum stressed area around the implant neck indicating a possible risk of the overloading in this area. In vivo observations did not validate generally progressive decrease of bone bed level in cases of short or considerably inclined implants.
