At New York Periodontics, guided bone regeneration, commonly known as GBR, is one of the procedures that makes our practice stand out. Bone grafting is a highly technique-sensitive procedure, and our clinicians are extensively experienced in rebuilding bone for dental implants, periodontal defects, ridge augmentation, and complex reconstructive cases.
We use a combination of advanced bone grafting materials, biologic materials, membranes, and precise surgical techniques to help make bone regeneration more predictable. In many cases, bone grafting is not simply about placing graft material into a defect. It requires detailed diagnosis, careful planning, proper material selection, soft tissue management, biologic support, and long-term maintenance.
Many patients come to us for second opinions after previous grafting procedures have failed. These cases have reinforced our belief that successful regeneration depends on using appropriate, high-quality materials and applying them with experience, precision, and a clear biologic strategy.
Guided bone regeneration is a surgical technique used to rebuild lost or missing bone. During GBR, bone grafting material is placed into an area where bone has been lost or is deficient. A membrane is often placed over the graft to protect the area and guide the healing process.
The membrane acts as a barrier, helping prevent fast-growing soft tissue from entering the grafted area too quickly. This allows slower-growing bone-forming cells the time and space needed to regenerate bone.
The goal of GBR is to create enough healthy bone volume to support teeth, dental implants, gum tissue stability, and long-term oral function.
Patients may need GBR when there is not enough bone to support a tooth, implant, or future dental restoration. Bone loss can occur for many reasons, including:
GBR is commonly used before or during dental implant treatment when the jawbone is too thin, too short, or irregularly shaped to support an implant in the ideal position.
Dental implants require adequate bone volume for stability, proper positioning, and long-term success. Without enough bone, an implant may need to be placed in a compromised position, which can affect function, esthetics, hygiene access, and longevity.
At New York Periodontics, we select bone grafting materials based on the type of defect, the patient’s biology, the treatment goal, the size of the graft, and whether implant placement is planned. Bone grafting materials may include:
Autogenous Bone
Autogenous bone is bone taken from the patient’s own body, usually from another area of the mouth. It contains the patient’s own living cells and natural bone-forming properties.
Autogenous bone may be used in more complex defects or when strong regenerative potential is needed. Because it comes from the patient’s own body, it is biologically compatible. However, it may require an additional surgical site and must be carefully planned.
Allograft Bone
Allograft bone is donor bone obtained from a human tissue bank. It is carefully processed, sterilized, and prepared for dental bone grafting. Allografts are commonly used in periodontal and implant-related bone regeneration because they provide a scaffold that supports new bone formation.
Allograft bone is widely used, well studied, and considered safe when sourced from accredited tissue banks and used appropriately.
Xenograft Bone
Xenograft bone is bone grafting material derived from another species, commonly bovine, and processed to remove organic components. It provides a slow-resorbing scaffold that helps maintain bone volume over time.
Xenograft materials are often useful for ridge preservation, sinus augmentation, implant site development, and defects where long-term volume stability is important.
Synthetic Bone Grafts
Synthetic bone grafts are man-made materials designed to support bone regeneration. These may include calcium phosphate, beta-tricalcium phosphate, hydroxyapatite, or other biocompatible materials.
Synthetic grafts can be useful in selected cases and may be combined with biologic materials depending on the regenerative goal.
Biologic Materials
At New York Periodontics, we frequently combine bone grafts with biologic materials to enhance the healing environment and improve predictability. These may include: PRF, PDGF, BMP, EMD, Collagen membranes and other regenerative adjuncts.
Biologic materials may help support blood vessel formation, cellular recruitment, soft tissue healing, graft stability, and bone regeneration. In larger or more complex grafts, biologic support can be especially important.
Membranes
Membranes are a critical part of many GBR procedures. They help protect the graft and guide the healing process. Depending on the case, we may use resorbable collagen membranes, non-resorbable membranes, titanium-reinforced membranes, or other barrier materials.
The choice of membrane depends on the size of the defect, the amount of space that must be maintained, the location of the graft, and the desired healing response.
Guided bone regeneration is considered a safe and well-established procedure when performed by experienced clinicians using proper technique and high-quality materials. Every material placed into the body is selected carefully based on safety, biologic compatibility, scientific evidence, and the needs of the patient.
At New York Periodontics, we review each patient’s medical history, medications, healing capacity, bone anatomy, and treatment goals before choosing the grafting approach. This is especially important for patients with diabetes, autoimmune conditions, smoking history, osteoporosis medications, history of radiation therapy, or other medical factors that may affect healing.
Each bone grafting material has a specific purpose and safety profile.
Autogenous bone is highly biocompatible because it comes from the patient’s own body. The main consideration is that it may require a second surgical site.
Allograft bone is processed through regulated tissue banks and is commonly used in dentistry and medicine. It is screened and sterilized to meet safety standards.
Xenograft bone is extensively processed to make it biocompatible and has a long history of use in dental bone regeneration.
Synthetic grafts are manufactured from biocompatible materials and avoid the use of donor or animal-derived tissue.
Biologic materials are selected based on the patient’s needs and the clinical indication. When used appropriately, they can help support a more favorable healing response.
No grafting material is appropriate for every situation. The key to safety and predictability is selecting the right material for the right defect and using it with proper surgical technique.
Large bone grafts require significant planning. The surgeon must understand bone biology, blood supply, wound closure, membrane stability, graft containment, implant positioning, and soft tissue management. Even high-quality materials can fail if the case is not planned or executed properly.
At New York Periodontics, our experience with complex grafting allows us to manage cases involving:
