CBCT-guided sinus augmentation by board-certified periodontist Dr. Chanook David Ahn. Over 5,000 implants placed with lateral window and crestal approaches enhanced by PRF therapy. Centrally located in Costa Mesa, serving patients across Orange County.
If you need dental implants in your upper jaw but lack sufficient bone, a sinus lift is the procedure that makes implant placement possible. A sinus lift, also known as sinus augmentation or sinus floor elevation, adds bone to the posterior maxilla by elevating the sinus membrane and packing bone graft material into the space created. This new bone provides the height and density required to anchor dental implants where bone has been lost to tooth extraction, periodontal disease, or the natural expansion of the maxillary sinus over time.
Orange County residents seeking sinus lift surgery benefit from having a board-certified periodontist with advanced training and extensive implant experience right in the heart of the county. Dr. Chanook David Ahn at The Loft Dental Studio in Costa Mesa has placed over 5,000 dental implants throughout his career, and sinus augmentation is one of the procedures he performs most frequently. His practice is centrally located in the South Coast Metro area, making it easily accessible from every corner of Orange County via the 55, 405, and 73 freeways.
Many Orange County patients are referred to The Loft Dental Studio by their general dentists specifically for sinus lift surgery because the procedure requires a level of surgical skill and anatomical knowledge that goes beyond routine implant placement. The maxillary sinus is a large, air-filled cavity that sits directly above the upper back teeth, and the membrane lining it (the Schneiderian membrane) is a delicate tissue only 0.3 to 0.8 millimeters thick. Successfully elevating this membrane without perforation, placing bone graft material in the correct volume, and determining whether simultaneous implant placement is feasible all require specialist training and clinical judgment that Dr. Ahn brings to every case.

Choosing the right specialist for sinus lift surgery is one of the most important decisions you will make in your implant journey. Dr. Chanook David Ahn brings a combination of credentials, technology, and clinical experience that few providers in Orange County can match. Here is what sets his approach apart.
Dr. Ahn completed his periodontal residency at Yale-New Haven Hospital and the VA Greater Los Angeles Healthcare System (UCLA-affiliated), where he received extensive training in bone grafting, regenerative surgery, and implant site development. He is board-certified by the American Board of Periodontology, a distinction held by fewer than 40 percent of practicing periodontists. Board certification demonstrates mastery of regenerative biology, surgical technique, and clinical decision-making through a rigorous examination process. This training is directly relevant to sinus lift surgery, which requires an understanding of membrane biology, bone graft physiology, and microsurgical precision.
Every sinus lift at The Loft Dental Studio begins with a CBCT (cone beam computed tomography) 3D scan. This in-office imaging technology provides a three-dimensional view of the maxillary sinus with sub-millimeter accuracy, revealing residual bone height, sinus septa, membrane thickness, and sinus pathology that two-dimensional X-rays simply cannot show. Dr. Ahn uses this information to select the optimal surgical approach, plan the precise location and dimensions of the bony window or osteotomy, and determine whether simultaneous implant placement is feasible. CBCT-guided planning reduces surgical time, minimizes complications, and improves outcomes.
Dr. Ahn incorporates PRF (Platelet-Rich Fibrin) therapy into every sinus lift procedure. PRF is prepared from a small sample of the patient's own blood, which is centrifuged during the procedure to concentrate growth factors and fibrin into a membrane. This PRF membrane is placed over the graft site to accelerate soft tissue healing, reduce post-operative inflammation and swelling, and support bone graft integration. PRF is derived entirely from the patient's own blood, so there is no risk of allergic reaction or rejection.
Experience matters in surgery. Dr. Ahn has placed over 5,000 dental implants throughout his career, including hundreds of cases involving sinus augmentation. This volume of experience means he has encountered and successfully managed virtually every anatomical variation, complication, and clinical scenario that can arise during sinus lift surgery. From thin membranes and large sinus septa to bilateral augmentation and revision cases, his experience allows him to adapt his technique in real time based on what he finds during surgery.
A sinus lift is not a one-size-fits-all procedure. The approach I choose, the graft material I select, and whether I place implants simultaneously or stage the procedure all depend on your specific anatomy, bone density, and treatment goals. That is why CBCT imaging is non-negotiable for me. I need to see your sinus in three dimensions before I plan your surgery. Combined with PRF therapy to accelerate healing, this individualized, evidence-based approach is why our outcomes consistently meet or exceed the published 95 to 97 percent implant survival rate in grafted sinuses. For a detailed look at the procedure itself, visit our comprehensive sinus lift page.
There are two primary approaches to sinus lift surgery, and the choice between them depends on your specific anatomy and how much bone needs to be added. Dr. Ahn is trained in both techniques and selects the approach that will deliver the best long-term result for each patient.
The lateral window approach is the gold standard when significant bone height needs to be gained. Dr. Ahn creates a small window in the lateral wall of the maxillary sinus, carefully elevates the Schneiderian membrane upward, and packs bone graft material into the space created. This technique can add 8 to 12 millimeters or more of vertical bone height, making it suitable for patients with as little as 1 to 2 millimeters of residual bone. Direct visualization of the membrane during the procedure allows for precise, controlled elevation and immediate repair if a perforation occurs.
The crestal approach is less invasive and is performed through the implant site itself. Using osteotomes or a hydraulic technique, Dr. Ahn gently pushes the sinus floor upward from below and places a small amount of bone graft material through the implant preparation site. This technique is best suited for cases requiring 2 to 4 millimeters of augmentation when at least 5 to 6 millimeters of residual bone is present. The crestal approach involves less surgical trauma, results in faster recovery, and almost always allows for simultaneous implant placement.
For a comprehensive, step-by-step breakdown of both approaches, including membrane elevation techniques, bone graft materials, and healing timelines, visit our detailed Sinus Lift Surgery in Costa Mesa page.

You may be a candidate for a sinus lift if you are missing one or more upper back teeth (premolars or molars) and plan to replace them with dental implants but do not have sufficient bone height between the jaw crest and the sinus floor. Generally, dental implants in the posterior maxilla require at least 10 millimeters of bone height for long-term stability. When a CBCT scan reveals less than this threshold, a sinus lift is typically recommended before or during implant placement.
Dr. Ahn's Save-First Philosophy: Before recommending extraction and implants with a sinus lift, Dr. Ahn always evaluates whether the natural tooth can be saved. If a compromised tooth has a viable prognosis with periodontal treatment such as LANAP laser gum treatment or guided bone regeneration, he will present that option first. Implants are an excellent solution when a tooth truly cannot be saved, but preserving natural teeth is always preferred when clinically justified.

Our team verifies your benefits before treatment so you understand your out-of-pocket costs upfront.
A lateral window sinus lift creates a small opening in the side wall of the maxillary sinus, allowing the surgeon to directly visualize and elevate the sinus membrane. It can add 8 to 12 millimeters or more of bone height and is suitable when residual bone is as little as 1 to 2 millimeters. A crestal sinus lift is performed through the implant site itself using osteotomes or a hydraulic technique, adding 2 to 4 millimeters of bone height when at least 5 to 6 millimeters of bone remains. The crestal approach is less invasive with faster recovery. Dr. Ahn selects the technique based on your CBCT scan and specific anatomy.
Initial recovery from a sinus lift takes about 7 to 14 days for a lateral window approach and 3 to 5 days for a crestal approach. Swelling peaks around days 2 to 3 and then gradually subsides. Most patients manage discomfort with over-the-counter ibuprofen by day 3. Key restrictions include no nose blowing for at least 2 weeks, no straws for 1 week, and no strenuous exercise for 5 to 7 days. The bone graft matures over 4 to 9 months depending on the technique and whether implants were placed simultaneously. Dr. Ahn monitors healing with periodic CBCT scans to determine optimal timing for implant placement.
Yes, simultaneous sinus lift and implant placement is possible and common when there is enough residual bone to stabilize the implant during healing. For a crestal approach, simultaneous placement is almost always performed. For a lateral window approach, at least 4 to 5 millimeters of residual bone is typically needed. When residual bone is less than 4 millimeters, a staged approach is recommended: the sinus lift heals for 6 to 9 months before implants are placed. Dr. Ahn evaluates your CBCT scan to determine which approach provides the best long-term outcome for your specific situation.
Some PPO dental insurance plans cover a portion of sinus lift surgery under oral surgery or implant-related benefits. Medical insurance may also provide coverage when the procedure is deemed medically necessary. Coverage varies significantly by plan. The Loft Dental Studio accepts most major PPO dental insurance plans including Delta Dental, Cigna, MetLife, Guardian, Aetna, United Healthcare, and Blue Cross Blue Shield.

A board-certified periodontist completes 3 additional years of surgical residency training beyond dental school, with extensive focus on bone grafting, membrane biology, and regenerative procedures. The sinus lift requires careful elevation of the Schneiderian membrane, a delicate mucoperiosteal tissue that periodontists are specifically trained to handle. Dr. Ahn's Yale residency training and board certification by the American Board of Periodontology demonstrate mastery of these advanced techniques. His experience with over 5,000 implant procedures means he has encountered and managed virtually every anatomical variation and complication that can arise during sinus augmentation.
