초록
Dental implants may be a valid prosthetic treatment to replace a single tooth, but there are some complications. One complication of dental implants is a fracture of the implant. This case report describes the implant fracture of a tissue-level implant. A patient with a tissue-level implant that was placed on the right maxillary first molar ten years ago visited the clinic because the implant prosthesis was fallen out with the fractured abutment screw. Panoramic radiograph confirmed the fracture of the abutment screw. After removing the screw fragment, a new restoration was applied. After two years, not only the screw but also the fixture was broken. The fixture fragment was surgically removed. This case implies that screw fractures can be a precursor to fixture fractures and regular check-up is necessary for preventing implant fractures.
Abstract
Dental implants may be a valid prosthetic treatment to replace a single tooth, but there are some complications. One complication of dental implants is a fracture of the implant. This case report describes the implant fracture of a tissue-level implant. A patient with a tissue-level implant that was placed on the right maxillary first molar ten years ago visited the clinic because the implant prosthesis was fallen out with the fractured abutment screw. Panoramic radiograph confirmed the fracture of the abutment screw. After removing the screw fragment, a new restoration was applied. After two years, not only the screw but also the fixture was broken. The fixture fragment was surgically removed. This case implies that screw fractures can be a precursor to fixture fractures and regular check-up is necessary for preventing implant fractures.
