Background and purpose: The aim of this study was to investigate the relationship between the implant survival rates and the length and diameter in disabled veterans attending Qazi Tabatabai Dental Clinic, Tehran, Iran during 2000-2010. Materials and methods: A retrospective study was conducted in 181 disabled veterans referring to Qazi Tabatabai Clinic. They received 1,255 implants from thr...

 longevity of osseointegrated implants are intensely influenced by biomechanical factors. Control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. In this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum Von Mises stress in implant-abutment complex and ja...

  Background : Although factors such as implant length, location, and diameter as well as bone quality have been associated with excessive failure rates, smoking is suggested as a stronger predisposing factor for higher failure rates. Thus, knowing the relationship between bone loss around the dental implants, maintenance of the implants and smoking could be a principle step towards solving the...
