Implant Placement In Sites With Adverse Anatomical And Biomechanical Conditions: Critical Review

OBJECTIVESTo focus on the main anatomical and clinical factors (sites with low bone density, limited bone mass or biomechanically unfavorable cases) that can affect the load that develops at the bone-implant interface during chewing.MATERIALS AND METHODSA critical review of articles that investigated osseointegration and survival rate of dental implants placed in anatomical and biomechanical adverse conditions was performed.RESULTSLow bone density limited amount of bone and biomechanically unfavorable cases are detrimental factors for success of implant rehabilitation. Several implant-prosthetic related factors affect the stress distribution at the bone-implant interface.CONCLUSIONSIn sites with adverse anatomical and biomechanical conditions it is important to reduce stress at bone-implant interface.
