Background/Aim:
Osseointegrated endosseous implants have proven to be a predictable prosthodontic treatment alternative for completely and partially edentulous patients.The success of dental implants is based primarily on the extent of osseointegration(2). The failure of dental implants is due not only to biological factors, such as unsuccessful osseointegration or the presence of peri-implantitis, but may also result from technical complications that can be divided into 2 groups : those relating to the implant components, and those relating to the prosthesis.(3).
The aim of this study is to release a complication as implant neck portion fracture related to bone loss around implant surface due to overloaded prostheses.
MaterialsandMethods: A 46-years-old male patient appealed to our clinic with missing some of his teeth and desiring to have dental implants.
Results: İmplant fracture is a rare and late biomechanical complications with a serious clinical outcome. Considering that implant placement is becoming increasingly popular, an increase in the number of failures due to late fractures to be expected. An early diagnosis of the signs alerting to implant fatigue, such as fracture, torsion or loosening of the post screws and prosthetic ceramic fracture, can help prevent an undesirable outcome.
Conclusion: Implant fracture is often preceded by other mechanical problems that can be interpreted as indicators of implant overload. It is important to avoid mechanical problems and excessive bone reabsorption in order to prevent implant fracture. The new implant replacing it should be as wide as possible, with due checking and adjustment of the occlusal forces in order to avoid overload.
