A 35-year-old woman with a traumatic bony defect region 11–14 due to a horse kick. a Clinical image of the traumatic avulsion of teeth and maxillary bone tooth locations 11–14 and partial avulsion of the lower lip. b Intraoperative photograph showing immediate implant placement after calvarial bone grafting to the maxilla. Using a prefabricated drill guide, the calvarial bone blocks were placed and fixed with microscrews in such a way that the implants could be placed between them in the prosthodontically required position. c After 4.5 years, the implant at location 11 had to be removed due to an infected osteosynthesis screw and peri-implantitis. The photograph of the grafted locations 13–14 showed that the screw heads were still in close contact with the previously grafted area. This observation underlines that there is minimal surface resorption of the calvarial bone almost 4.5 years of functional loading
