Kavčič J, Božič M. Fracture of an osseointegrated dental implant in an implant-supported mandibular overdenture. J Case Rep Images Dent 2021;7:100037Z07JK2021.ABSTRACT
Introduction: Implant fracture is a rare late biomechanical complication with incidence between 0.2% and 1.5%. Factors which may lead to this complication are irregularities in the design and material of the implant, prosthetic superstructure which is not passively connected to the implant and overload. Loosening of prosthetic superstructure, screw fracture, marginal bone loss and peri-implant inflammation are warning signs of implant fracture. Treatment alternatives are removal of the fractured implant, removal of the coronal part of the fractured implant with a new prosthetic post-placement into the remaining integrated part or just conservation of the remaining integrated part of the implant without post placement.
Case Report: A case report about a fracture of the abutment screw and later of an implant fracture and implant removal of the same patient will be presented.
Conclusion: Due to a growing number of patients receiving treatment with dental implants, the risk factors of dental implant fractures must be considered no matter which implant system is used and higher absolute numbers of fractures can be expected.
