Replantation of a Dental Implant at Sites of Previous Implant Failures using Guided Bone Regeneration

Here, we describe the successful replantation of a dental implant in a 69-year-old male patient who experienced early implant failure in the right mandibular posterior region (#46) owing to inadequate osseointegration.The patient presented with a narrow alveolar ridge and a class II dehiscence-type defect.A guided bone-regeneration (GBR) procedure using deproteinized bovine bone mineral and an absorbable collagen membrane was performed along with implant placement.Postoperative recovery was uneventful.After 6 weeks of postoperative recovery, healthy soft tissue healing was evident with no signs of infection or bone loss, demonstrating the effectiveness of GBR in managing implant failures with considerable bone defects.
