Aim: The present study was conducted to determine the prevalence rate of dental implants failure and risk factors affecting dental implant outcome. Materials and Methods: The present retrospective study was conducted on 826 patients who received 1420 dental implants in both genders. Length of implant, diameter of implant, location of implant, and bone quality were recorded. Risk factors such as habit of smoking, history of diabetes, hypertension, etc., were recorded. Results: In 516 males, 832 dental implants and in 310 females, 588 dental implants were placed. Maximum dental implant failure was seen with length < 10 mm (16%), with diameter < 3.75 mm, and with type IV bone (20.6%). The difference found to be significant (P < 0.05). Maximum dental implant failures were seen with smoking (37%) followed by hypertension (20.8%), diabetes (20.3%), and CVDs (18.7%). Healthy patients had the lowest failure rate (4.37%). Conclusion: Dental implant failure was high in type IV bone, dental implant with < 3.75 mm diameter, dental implant with length < 10.0 mm, and among smokers.
