Despite that, several complications involve dental implants may still happen and dental surgeons should be attentive to such problem, to prevent implant failures and biomechanical problems. One of the most serious late implant complications is the fracture of implant fixture. It can be a challenge for dentists to determine the etiology of fixture fractures. Aim of study: Evaluate the effect of some implant parameters, such as length, diameter and position, on the occurrence of fixture fracture and to determine the incidence of fractures reported in 5-10 years of fallow up. Materials and methods: Clinical retrospective study included 439 implants made of titanium alloy(Ti-6Al-4V) placed in 192 Iraqi patients; 103 male patients and 89 female patients with partially and completely edentulous areas had consulted the implant department at Al- Elwiya specialized dental center in Iraq. Results: In this study 439 fixtures distributed in 192patients; 53, 6% was male patients; 46.3% female patients.3 fixtures fracture reported in this study represent 1.5% in relation to total number of patients. 0.6% of the 439 fixtures installed. 71 fixtures 16.1% supported prosthesis with Pontics; that reported 3 fixtures fracture 4.2%, while 368 fixtures 83.8% supported prosthesis without Pontics in which no fracture of fixtures were recorded. Discussion &Conclusion: Fracture of Osseo integrated dental implants is a late complication, it has low incidence, the fracture of dental implants fixture are multifactorial, and the most common cause for fracture is the biomechanical or physiologic overload.
