Annals of International medical and Dental Research. 2019 May; 5(3): 1-32395-28222395-2814http://imsear.searo.who.int/handle/123456789/189222The present study was conducted to evaluate factors affecting success rate of dental implants. Methods: This retrospective study was conducted in the department of Prosthodontics. Patients who underwent dental implant therapy in last 2 years were included. Information such as name, age, gender, length of implant, diameter of implant, location of implant, bone quality was retrieved from the patient’s record file. Results: out of 2350 implants, age group <40 years had males (450) and females (520), age group 41-60 years had males (430) and females (410), age group >60 years had males (320) and females (220). 32 implants with length less than 10mm showed failure, 40 implants out of 900 implant with length 10-11.5mm showed failure and 14 implants out of 350 implants with size >11.5mm showed failure. The difference was significant (P < 0.05). Out of 600 implants placed in bone with type I quality, 1 showed failure. Out of 1050 implants placed in bone with type II quality, 50 showed failure. Out of 500 implants placed in bone with type III quality, 30 showed failure. Out of 200 implants placed in bone with type IV quality, 5 showed failure. The difference was significant (P < 0.05). Conclusion: Authors concluded that factors such as diameter of dental implant and quality of dental bone affects the success rate of dental implants.ImplantsOsseointegrateSuccessJournal ArticleIndiaAssistant Professor, Department of Dentistry, VSSIMSAR, Burla, Sambalpur, Odisha Pin-768017, India.
