The following case represent minimally invasive, simple, and most effective surgical protocol to reconstruct a large bone deficiency in the aesthetic zone ,and at the same time to preserve the papilla.
The patient came to our office complaining of mobility and discomfort of teeth 8,9 (11,21). Clinical and radiographic evaluation confirmed the patient’s complaint. The CBCT demonstrates a large bone deficiency at the apical level with absence of the buccal plate. The augmentation was preformed according to minimal invasive Bond Apatite Protocols. After the extractions, one vertical
incision was performed distally at a distance of one tooth from the defect site of tooth 8(11).
The vertical incision does not go beyond 3 mm in to the MGJ. The flap was reflected and complete debridement was done.
At this stage Bone Apatite bone cement was activated and injected directly into the site, followed by compaction of the cement in to place by using a sterile gauze and finger pressure for 3 seconds followed by a periosteal elevator for additional pressure above the gauze for 2-3 seconds more on the buccal and occlusal (it is very important that the cement will be well compacted).
Immediately after stabilizing the cement in place soft tissue closure took place by stretching the mesial corner of the flap and Suturing it, then the distal ,then the middle portion. Due to the fact that there was one wall of bony frame in between the two incisors, a complete closure was not required and a large exposure gap can remain. However, the cement must be protected until secondary soft tissue healing takes place, therefore a simple collagen sponge was secured above . A temporary Maryland bridge was used during the healing period. Reentry for implant placement took place at 3 months. Healing was uneventful.
Keratinized soft tissue bridged the exposed gap , the papilla was preserved in place.
Complete bone formation can be seen clinically and radiographically .

Have you ever used the material as a "binder" for other graft materials? Thanks for sharing. Augma is very simple to use and incorporate but I do not utilize it by itself for LARGE 3D defects. regards Dr. Salama

Bond Apatite is a composite bone graft cement which is already composed of biphasic calcium sulfate with Hydroxyapatite particles therefore it can be used by itself also for large 3D defects and no need to be mixed with other graft materials .
On the other hand 3D bond is a graft binder cement which is a pure biphasic calcium sulfate that can be used by itself only for socket grafting and for large defects should be used as a binder with other graft materials
