Advanced bone grafting procedures by board-certified periodontist Dr. Chanook David Ahn. Ridge augmentation, socket preservation, and PRF therapy to rebuild jawbone for dental implants. Located in Costa Mesa, just 10 minutes from Santa Ana via Bristol St or I-55 S.
Bone grafting is a surgical procedure that rebuilds or augments the jawbone using transplanted bone material. When teeth are lost or extracted, the surrounding alveolar bone begins to resorb because it no longer receives the mechanical stimulation that tooth roots provide during chewing. This progressive bone loss can reduce the jaw ridge to a fraction of its original dimensions within just a few years, making dental implant placement difficult or impossible without intervention. Bone grafting restores the volume and density of the jawbone so that it can support dental implants or other restorative treatments.
The biological principle behind bone grafting involves a process called osteogenesis, in which new bone cells form within and around the graft material. The graft serves as a scaffold, providing a three-dimensional framework that the body's own bone cells can migrate into and gradually replace with living bone tissue. This process is supported by osteoinduction, where proteins within certain graft materials actively stimulate the differentiation of stem cells into bone-forming osteoblasts, and osteoconduction, where the graft's physical structure guides new bone growth along its surface. The combination of these biological mechanisms allows the body to regenerate bone in areas where it has been lost.
At The Loft Dental Studio in Costa Mesa, board-certified periodontist Dr. Chanook David Ahn performs bone grafting procedures using advanced techniques including PRF (Platelet-Rich Fibrin) therapy, CBCT 3D imaging for precise treatment planning, and a selection of graft materials tailored to each patient's specific clinical situation. With over 5,000 implants placed throughout his career, Dr. Ahn understands the critical relationship between bone quality and long-term implant success. Every grafting procedure is planned with the end goal in mind, whether that is a single implant, a full-arch restoration, or preservation of the ridge for future treatment options.
Ridge augmentation is a bone grafting procedure designed to restore the height and width of the alveolar ridge after significant bone loss has occurred. When teeth have been missing for an extended period, or when multiple teeth were extracted without socket preservation, the jaw ridge can narrow and flatten to a degree that makes implant placement impractical. Ridge augmentation rebuilds this foundation to the dimensions required for successful implant integration.
Horizontal bone loss causes the ridge to become too narrow to accommodate an implant of adequate diameter. This is the most common type of ridge deficiency and is typically addressed with particulate bone graft material placed against the narrowed ridge, often supported by a resorbable or titanium-reinforced membrane to contain the graft and prevent soft tissue from growing into the graft site before bone has had a chance to form. Dr. Ahn uses guided bone regeneration (GBR) techniques to predictably restore ridge width, creating sufficient bone for implant placement in 4 to 6 months.
Vertical bone loss reduces the height of the ridge, which presents a more complex reconstructive challenge. In the upper jaw, vertical deficiency in the posterior region is often addressed with a sinus lift procedure. In other areas, vertical augmentation may require block bone grafts, tenting screws, or a combination approach using particulate graft material with rigid membrane support. Dr. Ahn evaluates each case individually using CBCT imaging to determine the most predictable approach for restoring adequate bone height.
Why Ridge Augmentation Matters for Implant Success: Dental implants require a minimum of approximately 6 millimeters of bone width and 10 millimeters of bone height for standard-diameter implants. When the ridge falls below these dimensions, placing an implant without augmentation risks poor primary stability, implant thread exposure, and long-term failure. Ridge augmentation creates the structural foundation that allows implants to be placed in an ideal prosthetic position with adequate bone coverage on all sides.
Socket preservation is a bone grafting procedure performed immediately after a tooth is extracted to prevent the rapid bone resorption that naturally follows tooth removal. Research consistently demonstrates that without socket grafting, the extraction site can lose 30 to 50 percent of its width within the first 12 months and continue to resorb for years afterward. This bone loss occurs because the bundle bone, the thin layer of bone that lines the tooth socket, is dependent on the periodontal ligament for its blood supply. Once the tooth and ligament are removed, this bone layer resorbs, and the surrounding ridge narrows and shortens.
During socket preservation, Dr. Ahn carefully extracts the tooth while preserving as much of the surrounding bone walls as possible. The empty socket is then filled with bone graft material and covered with a collagen membrane or PRF membrane to protect the graft and promote organized healing. The graft material fills the void where the tooth root was and provides a scaffold for new bone formation, maintaining the ridge dimensions that would otherwise collapse.
In some cases, a dental implant can be placed immediately at the time of extraction, eliminating the need for a separate grafting and healing phase. This is called immediate implant placement. However, immediate placement is only appropriate when there is adequate bone surrounding the socket for primary implant stability, the extraction socket is free of infection, and the bone walls are intact. When these conditions are not met, socket preservation followed by delayed implant placement in 3 to 4 months produces a more predictable outcome. Dr. Ahn evaluates each extraction site individually to determine which approach will deliver the best long-term result.
I recommend socket preservation for nearly every extraction where a dental implant is planned. The modest investment in socket grafting at the time of extraction consistently saves patients from needing a larger, more expensive ridge augmentation procedure later. It is far easier and more predictable to maintain bone than to rebuild it after significant resorption has already occurred. When I coordinate with a referring general dentist on an extraction, we plan the socket preservation together so the site is optimally prepared for implant placement.
The selection of bone graft material is a critical decision that Dr. Ahn makes based on the type of deficiency, the volume of bone needed, the location in the jaw, and the patient's medical history. Each material offers distinct biological properties and advantages.
In many cases, Dr. Ahn uses a combination of materials to leverage the advantages of each. For example, a ridge augmentation may combine allograft particles for their osteoinductive properties with xenograft particles for long-term volume stability, all enhanced with PRF therapy to deliver concentrated growth factors directly to the graft site.
Dr. Ahn incorporates Platelet-Rich Fibrin (PRF) therapy into virtually every bone grafting procedure at The Loft Dental Studio. PRF is derived from the patient's own blood, which is drawn at the beginning of the appointment and centrifuged to separate the platelets and fibrin from the red blood cells. The resulting PRF membrane is rich in growth factors including PDGF, TGF-beta, VEGF, and BMP, which play critical roles in wound healing and bone regeneration.
When mixed with bone graft material or placed as a membrane over the graft site, PRF delivers these concentrated growth factors directly where they are needed most. The fibrin matrix also serves as a natural scaffold that supports cell migration and provides sustained growth factor release over 7 to 14 days, the critical early healing window. Clinical studies demonstrate that PRF-enhanced bone grafts show improved vascularization, faster soft tissue healing, reduced post-operative swelling, and enhanced graft integration compared to grafts without PRF supplementation.
PRF therapy requires no synthetic additives and uses only the patient's own blood components, making it a fully biocompatible enhancement with no risk of allergic reaction or disease transmission. Dr. Ahn provides PRF at no additional charge for bone grafting procedures.
Bone graft procedures can broadly be categorized by the physical form of the graft material used. The choice between block grafts and particulate grafts depends on the severity and geometry of the bone deficiency.
Particulate grafts use small granules of bone material that are packed into the defect site. These granules create an interconnected scaffold that bone cells can infiltrate from all directions. Particulate grafts are the most commonly used form and are ideal for socket preservation, moderate ridge augmentation, and sinus lifts. They adapt well to irregular defect shapes and can be mixed with PRF for enhanced handling and biological activity. Most bone grafting procedures at The Loft Dental Studio use particulate grafts because they provide predictable results for the majority of clinical situations.
Block grafts involve transplanting a solid piece of bone, either harvested from the patient (typically from the chin or the back of the lower jaw) or obtained from a tissue bank. Block grafts are reserved for severe ridge deficiencies where the volume of bone needed exceeds what particulate material alone can reliably restore. The block is shaped to fit the defect, secured with titanium fixation screws, and often supplemented with particulate graft material around its edges. Block grafts provide structural support and are particularly useful for vertical augmentation where the graft must resist the compressive forces of the overlying soft tissue. Recovery from block graft procedures is typically longer than from particulate grafts, and implant placement usually requires a 5 to 6 month healing period.
Bone grafting is indicated in a variety of clinical situations. Understanding when grafting is necessary helps patients make informed decisions about their treatment.

The Loft Dental Studio is located at 3151 Airway Ave, Suite F-103, in the South Coast Metro area of Costa Mesa. Our office is easily accessible from Santa Ana and throughout Orange County.
From central Santa Ana, take Bristol St south toward Costa Mesa. Continue on Bristol St for approximately 3 miles until you reach the South Coast Metro area. The drive takes about 10 minutes in normal traffic. Alternatively, take the I-55 S (Costa Mesa Freeway) south toward Newport Beach and exit at Baker St or South Coast Dr. Our office is just minutes from the freeway in the Airway Business Center.
Healing time depends on the type and extent of bone grafting performed. Socket preservation grafts typically require 3 to 4 months of healing before an implant can be placed. Ridge augmentation procedures involving larger volumes of bone graft material generally need 4 to 6 months for the graft to fully mature and integrate with your natural bone. Block bone grafts for severe deficiencies may require 5 to 6 months. Dr. Ahn uses CBCT 3D imaging to evaluate graft maturation and determine the optimal timing for implant placement. PRF therapy is used at the time of grafting to accelerate healing and improve graft incorporation.
Bone grafting is performed under local anesthesia, so the procedure itself is painless. IV sedation, oral sedation, and nitrous oxide are also available for patients who prefer additional comfort. Post-operative discomfort is typically mild to moderate and peaks on days 2 to 3 before gradually subsiding. Most patients manage comfortably with over-the-counter ibuprofen and a short course of prescription pain medication. Swelling is normal and usually resolves within 5 to 7 days. Dr. Ahn uses PRF therapy and microsurgical techniques to minimize tissue trauma and promote faster recovery. Most patients return to work within 1 to 2 days.
Bone graft failure is uncommon but can occur. Warning signs include persistent or worsening pain beyond the first week, significant swelling that increases rather than decreases after day 3, visible graft material leaking from the surgical site, pus or foul-tasting drainage from the area, and the graft feeling loose or mobile. If you experience any of these symptoms, contact The Loft Dental Studio immediately. Early intervention can often salvage a compromised graft. Risk factors for graft failure include smoking, uncontrolled diabetes, infection, and premature mechanical disturbance of the graft site. Dr. Ahn discusses risk factors during your consultation and provides detailed post-operative instructions to maximize success.
Yes, and in most cases it should be. Socket preservation grafting performed at the time of extraction is one of the most effective ways to prevent the significant bone loss that naturally occurs after a tooth is removed. Without grafting, the extraction socket can lose 30 to 50 percent of its width within the first year. By placing bone graft material into the socket immediately after extraction, Dr. Ahn preserves the ridge dimensions and creates a solid foundation for a future implant. This approach also eliminates the need for a separate, more extensive ridge augmentation procedure later. Dr. Ahn coordinates with general dentists throughout Orange County to plan extractions with simultaneous socket preservation.
Bone graft costs vary based on the type and extent of the procedure. Socket preservation grafting at the time of extraction typically ranges from $500 to $1,200 per site. Ridge augmentation using particulate graft material ranges from $1,500 to $3,500 depending on the size of the deficiency. Block bone grafts for severe ridge deficiencies range from $2,500 to $5,000. These fees include the bone graft material, PRF therapy, and follow-up visits. Many PPO dental insurance plans provide partial coverage for bone grafting when it is performed in preparation for dental implants or to treat periodontal defects. The Loft Dental Studio offers financing through CareCredit and accepts FSA and HSA funds.
Many PPO dental insurance plans cover bone grafting partially, particularly when it is performed to treat periodontal bone loss or as a medically necessary step in preparation for dental implants. Coverage typically ranges from 50 to 80 percent of the allowed fee depending on your specific plan. Socket preservation at the time of extraction is increasingly covered by insurance plans that recognize its role in preventing further bone loss. The Loft Dental Studio accepts most major PPO dental plans including Delta Dental, Cigna, MetLife, Guardian, Aetna, United Healthcare, and Blue Cross Blue Shield.
