Sinus Lift Surgery in Federal Way
 If you’re researching sinus lift surgery in Federal Way, WA, 253 Dental Care performs this implant-prep procedure for patients whose upper jaw doesn’t have enough bone height to support a dental implant directly. The procedure rebuilds bone in the upper back jaw so an implant can be anchored where it otherwise couldn’t, and our team handles the planning scan, the surgery itself, and the implant placement that follows months later.
A sinus lift is sometimes called a sinus augmentation or a sinus graft. Despite the name, it is not a treatment for sinusitis, allergies, or any nasal or breathing condition. It’s a dental procedure focused on the bone in the upper back of the mouth, where the maxillary sinuses sit just above where the upper molar roots used to be. When those molars are missing and the bone between the gum and the sinus floor is too thin, an implant cannot be placed without first gently lifting the sinus membrane and adding bone material in the space underneath.
Sinus lift surgery is a specialized procedure within Dr. Walker’s surgical scope. He has been performing dental implant surgery and related grafting work for decades, and the planning is built around 3D cone beam imaging that maps the exact relationship between your remaining bone and your sinus floor. Some sinus lift cases fall within in-office scope; others warrant referral to a local oral surgeon. The CBCT and the consultation tell us which is which before any surgical decision is made.

What Is Sinus Lift Surgery?
A sinus lift is a bone grafting procedure done in the upper back jaw, in the area where the maxillary sinuses sit above where the molar roots were. The maxillary sinuses are air-filled spaces in your face; their floor sits very close to where the upper molars are anchored. When those molars are extracted, the bone that supported them gradually thins, and the sinus floor can drop closer to the gum line as the body remodels. To place a dental implant in that area, there has to be enough bone height between the top of the implant and the sinus floor. If there isn’t, we lift the sinus floor gently and place graft material in the space underneath before setting the implant.
 The exact amount of bone height needed depends on the length of implant being placed and the health of the surrounding bone. Most upper-arch implants need at least 8 to 10 millimeters of bone height between the ridge and the sinus floor. The CBCT scan measures that distance precisely, which is what tells us whether a lift is needed and how much.
Why You’d Need One
Three scenarios bring most patients to a sinus lift consultation. The most common is the patient who lost an upper back molar years ago, never replaced it, and now wants an implant. The second is the patient whose upper molars were lost from periodontal disease, which often takes bone with it. The third is the patient who simply has shallow upper jaw bone naturally. Anatomy varies, and some people have less bone between their molar roots and their sinus floor to begin with. The CBCT scan shows us which scenario applies and exactly how much lift, if any, is needed.
The Two Approaches: Lateral Window vs. Crestal
Two surgical approaches are common in dental sinus lift work. The lateral window approach uses a small opening in the side of the upper jaw bone, where we lift the sinus membrane from below and place graft material in the created space. It’s the standard approach for cases that need a substantial lift. The crestal approach (sometimes called transcrestal) goes through the implant site itself, lifting the sinus floor a smaller amount through that single point of access. It’s appropriate for cases where only a small lift is needed, and we often perform it at the same appointment as implant placement. The CBCT shows which approach fits your anatomy.
When You Don’t Need a Sinus Lift
Not every upper-arch implant candidate needs a sinus lift. If you have at least roughly 8 to 10 millimeters of bone height between your jaw ridge and your sinus floor, the implant can usually go in directly. Some patients arrive thinking they need a sinus lift because a previous dentist mentioned it, only to find on the CBCT that the bone is adequate. The opposite also happens. Patients told elsewhere they don’t have enough bone for any implant find on imaging that a sinus lift makes the implant possible after all.
Your Sinus Lift Doctor in Federal Way
Dr. Mark Walker has been practicing dentistry since he graduated from the University of Washington School of Dentistry in 1981 and has performed dental implant surgery and related grafting procedures throughout his career. He is a member of the Academy of General Dentistry, the International College of Dentists, the American College of Dentists, and the Pierre Fauchard Academy. Sinus lift surgery is a specialized component of that surgical work, and Dr. Walker handles in-office cases that fall within routine surgical scope. Dr. Walker’s full bio covers his community service, board work with the Washington State Dental Association, and his post-graduate training history.
The reason this matters for sinus lift specifically: the surgical plan, the CBCT imaging, the lift itself, and the implant placement that comes months later all stay with the same surgeon. The records of how your sinus floor looked before, what was placed, and how the bone integrated are in the same chart. When the time comes to place the implant, the dentist who knows that history is the one doing the placement.
Some sinus lift cases fall outside in-office scope, including those with significant existing sinus pathology, certain medical histories, or anatomy that calls for IV sedation. In those situations, Dr. Walker will refer to a trusted local oral surgeon. Honest scope assessment is part of the consultation.
The Sinus Lift Process at Our Office
Most sinus lift procedures at our office move through four stages. The procedure itself is usually completed in a single appointment, but the healing window before the implant is placed is longer than for routine bone grafts.
Consultation and CBCT Planning
We start with a consultation and a 3D cone beam CT scan. The CBCT shows the exact height of bone available, the contour of your sinus floor, and the surrounding anatomy that the surgical plan needs to account for. That image determines whether a lift is needed at all, which approach is appropriate (lateral window or crestal), and how much graft material will be placed. It is also what tells us whether the case fits in-office surgical scope or warrants a referral.
Sedation and Comfort
You’ll choose your comfort approach during the consultation. Most sinus lift patients use a combination of local anesthesia, which fully numbs the surgical area, plus oral conscious sedation, which produces a deeply relaxed state for the procedure. Nitrous oxide is also available for patients who prefer a lighter approach. Oral conscious sedation requires a driver for the day; nitrous wears off within minutes. We do not offer IV sedation in-office; for patients whose case calls for it, we coordinate the procedure with a local oral surgeon.
The Sinus Lift Procedure
The actual surgery time depends on the approach. A lateral window sinus lift typically takes 60 to 90 minutes per side. A crestal sinus lift, when one is appropriate, is faster and is often performed at the same appointment as implant placement when bone height allows. We make a small access (lateral window or crestal, depending on the plan), gently lift the sinus membrane, place graft material in the created space, and close the access. We use a soft tissue laser where surgical access calls for it, which leads to less post-operative bleeding and swelling than a traditional scalpel approach.
Healing Window Before Implant Placement
Sinus lift grafts heal more slowly than routine socket preservation grafts because the graft material is integrating in a more anatomically constrained area. For most patients, the wait between sinus lift and implant placement is four to nine months, depending on the volume of graft and the approach used. We monitor the site at follow-up visits and confirm with imaging that the bone has fully integrated before placing the implant. Detailed aftercare instructions are in our post-op instructions library, including a dedicated sinus graft recovery sheet.
Benefits of Sinus Lift Surgery
The biggest practical benefit of a sinus lift is making an upper-arch implant possible when it otherwise would not be. At our office, the planning CBCT shows us not only whether you currently have enough bone, but whether the anatomy will support a successful long-term restoration. The lift often makes the difference between losing a back molar permanently to a denture or a bridge and replacing it with a permanent implant.
What You Gain from a Sinus Lift
| • |
A path to a permanent upper-arch implant – if you’ve been told elsewhere that bone loss closes off the implant option, the CBCT often shows that a sinus lift opens it back up
|
| • |
A long-term anchor in solid bone – the imaging-confirmed bone integration is what makes the implant stable for long-term function
|
| • |
A fixed alternative to a denture or bridge – the lift is what makes a single tooth implant possible at our office instead of falling back to removable options
|
| • |
Preserved upper-jaw bone structure – the same CBCT records show us how that bone holds over time at follow-up imaging
|
| • |
Imaging-confirmed healing – we verify with follow-up CBCT that the graft has integrated before placing the implant |
If a previous dentist told you an implant wasn’t possible because of bone loss in the upper jaw, the CBCT imaging is what tells you whether a sinus lift can change that answer.
Why Choose 253 Dental Care for Sinus Lift Surgery
Our office is a two-doctor general practice in Federal Way that performs in-house bone grafting and dental implant surgery, including sinus lift procedures within the practice’s surgical scope. Dr. Walker has been doing surgical implant work for over four decades, and the equipment we use to support sinus lift planning reflects that experience.
A few specifics matter for sinus lift surgery at this office. We use a cone beam CT scanner for surgical planning, which gives us a three-dimensional view of the maxillary sinus floor, the available bone height, and the precise anatomical relationships that drive the surgical plan. That detail is the foundation for choosing the lateral window or crestal approach, deciding whether the case fits in-office scope, and identifying any anatomy that warrants a referral. We use a soft tissue laser to make cleaner incisions when surgical access calls for it. And we offer oral conscious sedation in-office for patients who want a more relaxed experience than nitrous alone.
Continuity matters more in sinus lift cases than in routine grafting. Whether you’ve been a long-time patient or you’re coming in specifically for an upper-arch implant evaluation, the same team handles your imaging, your sinus lift, your healing follow-ups, and your eventual implant placement. The dentist who placed the graft is the dentist who places the implant months later, working from the same record of how your sinus floor looked before, what was placed, and how the bone responded.
Sinus Lift Cost and Financing
Cost matters, and we’ll be straight with you about what drives it. The cost of a sinus lift depends mainly on the approach used (a lateral window lift is more involved than a crestal lift), the volume of graft material needed, and whether we’re doing the lift at the same appointment as a separate procedure. We provide a clear estimate at the consultation once we’ve seen your CBCT imaging.
Insurance coverage for sinus lift surgery varies. Many dental plans cover at least a portion when it’s medically necessary as part of a documented implant treatment plan. Our front office team will verify your specific benefits before treatment and provides a written estimate, so we answer the insurance question before the procedure rather than after. For portions not covered by insurance, we work with third-party financing partners including CareCredit, Lending Club, and United Medical Credit, plus a loyalty program for patients without dental insurance.
A sinus lift is more expensive than routine socket preservation, but it is also the difference between making an upper-arch implant possible and not. For patients who want a permanent restoration in the upper back of the mouth, the lift is often the only path to that outcome.

Frequently Asked Questions
What is the difference between a sinus lift and treatment for sinusitis?
A sinus lift is a dental procedure that adds bone material to the upper jaw above the molars, in the area where the maxillary sinuses sit. Sinusitis is inflammation or infection of the sinus lining, which is treated by an ENT, allergist, or primary care physician. The two are unrelated. A sinus lift does not treat sinusitis, breathing problems, allergies, or any nasal condition; it is purely about creating enough bone to support a dental implant in the upper back jaw.
Does sinus lift surgery hurt?
During the surgery itself, no. The area is fully numbed with local anesthesia, and most patients also choose oral conscious sedation, which produces a deeply relaxed state for the procedure. Most of what you’ll feel is pressure rather than pain. Some swelling and mild discomfort during the first three to five days afterward are normal, and over-the-counter or prescribed pain medication typically handles them well. We’ll discuss the specific comfort plan at the consultation.
Will my sinus get infected after a sinus lift?
Sinus infection after a sinus lift is uncommon when patients follow post-op instructions and we plan the lift around healthy sinus anatomy. The most common risk factors for post-op infection are an existing sinus infection at the time of surgery (which is why we screen for that on the CBCT and through your medical history), heavy nose-blowing in the first week, and smoking. We provide specific post-operative instructions to minimize these risks. If a complication does develop, we manage it directly or coordinate with an ENT specialist.
How long is the recovery, and when can I get my implant?
Recovery in the surgical sense is relatively quick. Most patients return to routine activity within a few days. The wait before the implant can be placed is the longer part of the timeline. For most patients, that wait is four to nine months, depending on the volume of graft and the approach used. We confirm with follow-up imaging that the bone has integrated before placing the implant, so the timeline is based on what your healing actually looks like, not a fixed calendar.
Am I a candidate for a sinus lift in Federal Way?
Candidacy depends on your specific anatomy, your medical history, and the type of restoration you’re planning. Most patients who lost an upper back molar at any point and want an implant are candidates for evaluation, regardless of how long ago the tooth was lost. A CBCT scan at the first appointment shows exactly how much bone you have, where the sinus floor sits, and whether a lift is the right next step toward a permanent dental implant.
What if I’m not a candidate for a sinus lift?
Not every patient who could benefit from one is a candidate for it in our office. If the bone height is borderline, sometimes a shorter implant or a different placement strategy works without a lift. If the lift itself is too complex for in-office scope, we refer to a local oral surgeon. If you don’t want any surgical procedure beyond the implant, alternatives include a different bone grafting approach, a dental bridge, or a denture. The right call depends on what the imaging shows and what you want long-term.
Is a sinus lift more expensive than a regular bone graft?
Yes, generally. A sinus lift is more involved than routine socket preservation or ridge augmentation, both because of the surgical complexity and because of the amount of graft material we often need to place. The cost reflects that. For patients who want a permanent upper-arch implant, however, the lift is often the only path to that outcome; alternatives like dentures or fixed bridges have their own costs and trade-offs over time.
Can I have a sinus lift and an implant at the same appointment?
Sometimes, yes. When the bone height is just slightly insufficient and a small crestal lift is enough to create the additional space needed, the lift and the implant can be done at the same appointment. When a more substantial lateral window lift is needed, we place the implant separately, typically four to nine months later, after the graft has fully integrated. The CBCT scan tells us which scenario applies to your case.
