Purpose: Implant-supported restorations have become the standard treatment for edentulous patients. However, several complications have been reported, including implant-fixture fracture. This study aimed to determine the risk factors for dental implant-fixture fracture by evaluating 43 fractured implant fixtures in 33 patients.

Materials and Methods:This study included patients referred from local clinics owing to implant fracture between 2006 and 2023. The implant type and location, method for removal, and risk factors for implant fracture were investigated.

Results:This study included 22 men and 11 women (mean age, 60.8 years; range, 33–82 years). Implant fracture was twice as common in men than in women. Fractures were more common in fixtures with internal connections rather than in those with external connections. More implant fractures were observed in patients with single implants than in those with multiple implants.

Conclusion: Since the only solution to implant fracture is removal, regular follow-up and biomechanical and biological considerations to reduce dental implant fracture are necessary.
