Background: The present case report study aims to describe, from both clinical and histological aspects, the bone healing pattern in a patient under oral bisphosphonates therapy. Case Presentation: an 82-year-old female patient has been under oral nitrogen bisphosphonates therapy for two years. She underwent a tooth extraction. After four months, two bone biopsies were harvested, during standard implant drilling procedures. The first one corresponded to the healed alveolar socket of the previously extracted tooth (specimen A), while the second one corresponded to the bone ridge that was edentulous before starting the bisphosphonates therapy (specimen B). Morphometric and histologic analyses were performed. Results: In both, the bone resulted vital and no evidence of empty lacunae was detected. A reduction in the haversian canal diameter was observed in specimen B. The present case report highlights histological findings suggesting that patients undergoing oral bisphosphonates therapy may be eligible for surgical therapy. A pre-operative careful anamnesis and the observance of international guidelines for treating patients taking bisphosphonates are mandatory. Conclusions: These preliminary results will be used to plan a large clinical study in order to better understand the influence of bisphosphonates on the bone healing process.
