Soft tissue reactions around percutaneous implants: a clinical study of soft tissue conditions around skin-penetrating titanium implants for bone-anchored hearing aids.

摘要: Some patients with hearing impairment cannot use conventional aids. One solution for these is the of bone conduction aids; however, this kind equipment associated several problems related to necessity a good contact between transducer and temporal bone. Direct would be an ideal provided that safe reaction-free skin penetration permanent anchorage could achieved. Branemark et al have developed procedure furnish edentulous fixed bridges using titanium implants. This report focused on clinical status soft tissue adjacent 67 skin-penetrating devices in 60 patients. The been followed 3 96 months 313 occasions, which represents total observation time 1515 performance. Only one implant was extracted due adverse reaction, giving failure rate 0.07% per month. comparable cardiac pacemakers 0.02-0.04% month).
