Bone defect rehabilitation using lyophilized bone preshaped on a stereolithographic model

Abstract

Bone grafting provides ideal conditions to the patient's rehabilitation with dental implants. In addition, prototyped tridimensional models allow the surgical procedure to be simulated and enable important anatomic structures to be visualized. To present a bone defect rehabilitated with xenogenic bone preshaped on a stereolithographic model and the follow-up after 7 years of treatment. The present case report describes a bone defect rehabilitated with a lyophilized bone block preshaped on a stereolithographic model. The patient, a 56-year-old woman, was referred to the dental office presenting a bone defect in the anterior maxilla. Bone regeneration intervention was performed with xenogenic grafting and barrier membrane. The follow-up of the postoperative period and after 7 years is presented. After 7 years, the tomographic exam showed the maintenance of bone at the grafted site, representing the long-term success of the treatment.

“…In clinical practice, guided bone regeneration with bone grafts frequently precedes implant placement in cases where insufficient bone support is available for functional rehabilitation [18, 26]. Bone microarchitecture is an important component for bone quality and may influence implant stability and rehabilitation success [24].…”

“…Additionally, no toxicity or immunogenic reactions have been reported [14, 16, 17]. Clinical reports have indicated its potential for alveolar bone defects rehabilitation [18] and sinus floor augmentation [17]. However, limited evidence is available regarding the efficacy and resorption rate of LBMB in comparison to other bone graft materials [16, 19].…”
