Abstract

Fresh frozen allograft bone is routinely used in orthopedic surgery for the reconstruction of large bone defects, and its use in oral and maxillofacial surgery is increasing. The purpose of this case was to demonstrate the installation of dental implants and the use of fresh frozen bone for reconstruction of anterior maxilla in the same surgery. This case report presents the insertion of dental implants followed immediately by a placement of fresh frozen allograft in block and particle for a reconstruction of atrophic anterior maxillary in the same surgery. Ten months subsequent to this procedure, provisional fixed prosthesis was installed on the implants. Four months later (postoperative month 14), the final fixed prosthesis was installed and the clinical success was observed. The insertion of dental implants followed immediately by a placement of fresh frozen allograft is a safe and efficient process that results in the successful return of dental function and aesthetic rehabilitation for the patient.

Highlights

Bone grafting techniques are widely used in the restoration of atrophic maxillary bone prior to placement of dental implants
In 2014, Pereira and colleagues [1] performed a prospective cohort study aimed at clinically evaluating the extent of resorption over time of corticocancellous fresh frozen allograft bone blocks used in the reconstruction of severe maxillary atrophy
They found that the use of fresh frozen allograft bone harvested from the iliac crest is a suitable alternative in atrophic maxillary reconstruction and exhibited a low resorption rate at 5 months, which allowed for proper stability of dental implants prior to fixed prosthetic rehabilitation

Summary

Introduction

Bone grafting techniques are widely used in the restoration of atrophic maxillary bone prior to placement of dental implants. In 2009, Contar and colleagues [7] conducted a study of 15 patients with atrophy of the maxillary ridge who required bone block grafts prior to implant placement These patients underwent maxillary reconstructions performed with block grafts comprising fresh frozen chips harvested from allogeneic tibial bone. In 2014, Pereira and colleagues [1] performed a prospective cohort study aimed at clinically evaluating the extent of resorption over time of corticocancellous fresh frozen allograft bone blocks used in the reconstruction of severe maxillary atrophy They found that the use of fresh frozen allograft bone harvested from the iliac crest is a suitable alternative in atrophic maxillary reconstruction and exhibited a low resorption rate at 5 months, which allowed for proper stability of dental implants prior to fixed prosthetic rehabilitation. The purpose of this case was to demonstrate the installation of dental implants and the use of fresh frozen bone for reconstruction of anterior maxilla in the same surgery
