Guided bone regeneration (GBR) aims to augment the areas with osseous defects in compromised dentition. Bone grafting materials, barrier membranes and growth factor therapies have been utilized to minimize the dimensional changes in the bone morphology and architecture occurring postextraction. GBR procedures are performed using materials such as autografts, allografts, xenografts, or synthetic bone grafts or combination. Barrier membranes are used to maintain the space and prevent the infiltration of fibrous tissue. Such membranes are: non-resorbable PTFE membranes, collagen-based absorbable membranes, synthetic absorbable membranes, titanium mesh membranes and PRF.
In this case report, a 67 years-old lady was referred for implant rehabilitation in the right anterior maxilla. The reason of tooth loss was vertical root fracture. GBR was performed at the area of #12 and #13, due to severe bone defect. A combination of 50:50 allograft and xenograft bone grafting material, non-resorbable titanium membrane and PRF membranes was used. One-month post-op exposure of the membrane was noticed. At this point, it is important to be mentioned that on the day of the surgery primary closure was not achieved at the area #13, due to lack of soft tissue thickness. Replacement of the first membrane by a collagen based absorbable one and tension free suturing was performed. One month after the second intervention, soft and hard tissue healing was completed unhindered.
