Implantoprosthetic rehabilitation of a patient with severe form of hemophilia B: a case report

Abstract

The preparation of patients with hemophilia before surgical operations and dental procedures constitutes a significant clinical challenge. This article presents the implantoprosthetic rehabilitation of a patient with severe hemophilia B (factor IX activity <1%). The patient was prepared for the surgical procedure with recombinant factor IX concentrate (Rixubis) during the clinical surgery study. Tooth extraction and the implantation of four dental implants in the mandible were planned: one dental implant of 3.7 mm diameter and 10 mm length in the place of tooth 35, and another of 3.2 mm diameter and 10 mm length in the place of tooth 37. The next two implants were implemented 1 month later: one implant 3.7 mm in diameter and 10 mm in length in the place of tooth 46, and another implant 3.2 mm in diameter and 10 mm in length in the area of tooth 44. Appropriate substitution of the missing coagulation factor, together with the use of local hemostatic therapy, allowed dental implantation to be performed without excessive blood loss in this patient with severe hemophilia B.
