[Re-osseointegration of a Dental Implant with Aseptic Loosening after Occlusal Correction: a Case Report].

The preservation of osseointegration is fundamental for the long-term success of dental implants. Breakdown of osseointegration may occur in cases of aseptic implant loosening, a poorly understood process leading to sudden implant failure. So far, no evidence-based therapy concept exists for implants with aseptic loosening. The present case report demonstrates the re-osseointegration of a dental implant in the mandible of a 79-year-old female patient with mamma carcinoma after loss of osseointegration caused by aseptic loosening. The only treatment performed was a correction of the occlusion. After a period of eight months, a re-osseointegration was observed clinically and radiographically, and remained stable for the follow-up period of 21 months. Reduction of occlusal forces after correction of the occlusion may have facilitated a re-osseointegration. Potential influences of concurrent antineoplastic chemotherapy regarding breast carcinoma or further unknown influences on implant re-osseointegration cannot be ruled out.
