OBJECTIVE: This study aimed to evaluate the histologic examination of bone tissue surrounding three @entity702 implants, which were removed since the @entity1 presented with long-standing @entity158 in the implant area. The histologic examination was both qualitatively and quantitatively performed. Furthermore, could an explanation be obtained for the @entity158 in the implant area, which, after removal of the percutaneous implant, disappeared immediately? STUDY DESIGN: Retrospective case review; clinical histomorphometric. SETTING: University Hospital Nijmegen, G  teborg University, Sweden. @entity1 : Three @entity1 of a consecutive series of 189; 1 @entity1 and 2 @entity1 who had received a bone-anchored, percutaneous, skin-penetrating, commercially pure @entity702 implant in the temporal bone, on which a transducer was mounted. The implants were removed because of @entity158 in the implant area from the three @entity1 after 31 months, 18 months, and 8 months, respectively. MAIN OUTCOME MEASURES: The percentage of direct bone-to-metal contact was 81%, 59%, and 42%, respectively. The percentage of bone volume between the threads of the screw was 90, 78, and 75, respectively. RESULTS: The qualitatively histologic findings showed no major differences among the three investigated samples. Quantitatively, the amount of osseointegration depended on the duration of implantation. CONCLUSIONS: Direct bone-to-metal contact and the bone volume between the threads increased as the implantation time increased. No explanation was found for the @entity158 in the implant area and the relief of @entity158 after removal of the percutaneous implant.
