Osseointegrated Implants

by Dr. Bejan Iranpour (U of R)

Implants to replace various movable and load bearing human parts have been used for many years.  Osseointegration, direct bone-implant contact, is a requisite for success of load bearing implants. The implant-bone interface is an intricate biologic relationship with the ability to sustain itself by a constant remodeling process. Load variation and mechanical demands can both enhance or deplete the integrity of this interface. Molecular structure and surface charges between bone cells and alloplastic materials seem to be responsible for osseointegration.  Dental implants have become a predictable successful modality for restoring masticatory function. Dental implants also serve as excellent experimental models for interface and biomechanical studies.  This presentation explored the definition of osseointegration, maintenance of osseointegration, biologic and mechanical predictors, and investigative potentials.Biomechanical Engineering.
