Clinical analysis of dental implant surgery in patients undergoing antithrombotic therapy

Abstract

  Objective：Although dental implant surgery is an effective dental prosthesis technique, the management of patients undergoing antithrombotic therapy during this surgery remains unclear. The present study aimed to assess the management of such patients during the dental implant surgery and the occurrence of postoperative bleeding.

  Materials and Methods：We examined 28 dental implant surgeries performed in 21 patients undergoing antithrombotic therapy between January 2007 and December 2016.

  Results：Postoperative bleeding was recorded in 34.6% of patients undergoing antithrombotic therapy, and no serious bleeding complications were noted. The rate of postoperative bleeding was higher in patients undergoing therapy using warfarin than in those undergoing therapy using platelet aggregation inhibitor.

  The number of implant insertions in a single surgery and the type of surgical method employed（single- or two-staged procedure）did not significantly affect the occurrence of postoperative bleeding.

  During the observation period ranging from 10 days to 10 years, no implants were lost and no bleeding complications were reported.

  Conclusion：These results indicate that antithrombotic therapy should be continued in patients undergoing dental implant surgery. However, meticulous follow-up of the patient following the dental implant surgery is required.
