When the Sinus Sits Where Your Implant Needs to Go
The maxillary sinus is an air-filled cavity that sits directly above the roots of your upper premolars and molars. When upper back teeth are lost, two things happen simultaneously: the alveolar bone beneath the sinus resorbs from lack of stimulation, and the sinus floor drops (pneumatizes) into the space the roots once occupied. The result is often less than 3-4mm of bone between the ridge crest and the sinus floor — far too little to support a dental implant, which typically requires 8-10mm of bone height.
A sinus lift solves this. Dr. Walied Eldomiaty improves the Schneiderian membrane — the thin mucosal lining of the sinus — and places bone graft material beneath it, effectively creating new bone where the sinus had expanded. We perform both lateral window (open) sinus lifts, which provide access for larger augmentations, and crestal (internal) sinus lifts through the implant osteotomy for cases needing more modest elevation. The choice depends on how much vertical bone gain is needed, which is measured precisely on CBCT before surgery.
Sinus lift procedures at ADSC are performed under local anesthesia with IV sedation available. The lateral approach involves creating a small window in the lateral maxillary wall, carefully elevating the membrane, packing bone graft material into the created space, and covering the window with a collagen membrane. PRF is mixed with the graft material to accelerate vascularization and healing. Healing time is typically 6-9 months before the grafted bone is mature enough for implant placement — though in some cases, implants can be placed simultaneously with the sinus lift.
Clinical Perspective: Sinus Lift
“In our practice, we’ve found that successful Sinus Lift outcomes depend on three factors: precise diagnosis with 3D imaging, evidence-based treatment planning, and honest communication with the patient. At Aloha Dental Specialty Center, we invest time to get each of these right.”

Recovery & Healing Timeline
Understanding the healing process helps you plan ahead and follow post-operative instructions for the best possible outcome.
First 48 Hours
Mild swelling and tenderness are normal. Apply ice packs in 20-minute intervals and take prescribed or over-the-counter anti-inflammatory medication. Eat soft foods and avoid the surgical site when chewing.
Days 3 to 7
Swelling peaks around day three and then improves. The tissue begins closing over the surgical site. Continue with soft foods and use any prescribed antimicrobial rinse. Most patients return to normal activities during this phase.
Long-Term Healing
Surface tissue heals within two to three weeks. Bone integration and deep healing continue for three to six months. Avoid smoking, follow up as scheduled, and maintain good oral hygiene throughout recovery.
Questions during recovery? Call us at (503) 822-0096. We are available for post-operative concerns.
The Schneiderian Membrane and Sinus Biology
The Schneiderian membrane is a specialized respiratory mucosa approximately 0.3-0.8mm thick that lines the maxillary sinus. It consists of pseudostratified ciliated columnar epithelium with goblet cells that produce mucus. During sinus lift surgery, this membrane must be improved intact — a perforation allows graft material to enter the sinus cavity, increasing infection risk and potentially causing sinusitis. The membrane itself has osteogenic potential; studies have shown that periosteum-like progenitor cells in the Schneiderian membrane contribute to new bone formation on the membrane surface of the graft. This is why the membrane is improved but not removed — it actively participates in bone regeneration from above while the native bone floor contributes from below.
Why Choose ADSC?
Sinus lift surgery has a complication that is specific and consequential: membrane perforation. The reported incidence ranges from 7-35% depending on the study and the surgeon's experience. When the membrane tears, the surgeon must either repair the tear with a collagen membrane or, if the perforation is large, abort the procedure and allow healing before reattempting. Dr. Ostovar's experience with many sinus lifts — and his use of piezoelectric instruments that cut bone without damaging soft tissue — keeps perforation rates well below published averages. This is a procedure where surgical volume and refined technique directly translate to higher success rates.

A Note from Your Dental Team
In my experience, the patients who get the best results from sinus lift surgery beaverton are those who come in with realistic expectations and follow their post-treatment instructions carefully. I’d rather spend extra time explaining what to expect than have a patient be surprised later.
“Every patient I see has a different story, a different set of concerns, and a different definition of what ‘success’ looks like. That’s why I don’t believe in one-size-fits-all treatment plans. When you come in for a consultation, I’ll listen first, examine second, and recommend third.
I also won’t recommend a procedure you don’t need. If your tooth can be saved with a filling instead of a crown, I’ll tell you that. If watchful waiting is appropriate, I’ll explain why. My job isn’t to sell treatment — it’s to give you my honest clinical judgment so you can make an informed decision.
If you have questions about whether this treatment is right for you, or if you’ve been told you need this procedure by another dentist and want a second opinion, call us at (503) 822-0096. We’re happy to take the time to explain everything — no rush, no pressure.”

I know many patients feel anxious about dental procedures — you’re not alone in that. What I hear most often after treatment is: “That was so much easier than I expected.” We’re here to make this as comfortable as possible for you.
Are You a Candidate for Sinus Lift Surgery Beaverton?
Most patients in good general health are candidates for sinus lift surgery beaverton. However, certain factors may affect your eligibility or require modifications to the treatment plan:
- Medical conditions: Uncontrolled diabetes, autoimmune disorders, or blood-thinning medications may require coordination with your physician before treatment.
- Bone quality: For sinus lift surgery beaverton involving the jawbone, adequate bone density is essential. A CBCT 3D scan during your consultation determines this precisely.
- Smoking: Tobacco use significantly impairs healing. We strongly recommend quitting 2-4 weeks before and after any surgical procedure.
- Age: There is generally no upper age limit. What matters is your overall health, not your age. We have successfully treated patients in their 80s and 90s.
The only way to know for certain is a consultation with our team with a board-certified endodontist. Call (503) 822-0096 to schedule your evaluation — we’ll tell you honestly whether this is the right treatment for your situation.

Frequently Asked Questions
A sinus lift is a surgical procedure that adds bone to the upper jaw in the area of the premolars and molars by elevating the sinus membrane and placing bone graft material beneath it. It creates the bone height necessary for dental implant placement when the sinus has expanded into the space where bone once existed.
Upper back teeth sit directly beneath the maxillary sinus. After these teeth are lost, the bone between the ridge and the sinus floor thins — often to just a few millimeters. A standard implant requires 8-10mm of bone height. If your available bone is insufficient, a sinus lift builds the height needed to support implants securely.
A lateral (open) sinus lift accesses the sinus through a window created in the side wall of the maxilla. It allows for substantial bone augmentation — up to 10-12mm of height gain. A crestal (internal) sinus lift approaches the sinus from below through the implant site. It is less invasive but limited to gaining 3-5mm of height and requires at least 5-6mm of existing bone.
In some cases, yes. If you have at least 4-5mm of existing bone height below the sinus, we can perform a crestal (internal) sinus lift and place the implant simultaneously. If bone height is less than 4mm, a lateral window sinus lift is done first, followed by implant placement after 6-9 months of healing and bone maturation.
A lateral window sinus lift on one side takes approximately 60-90 minutes. A crestal sinus lift is faster, typically 15-20 minutes in addition to the implant placement time. Bilateral sinus lifts (both sides) are often performed in a single session, extending total surgical time to about 2-2.5 hours.
Surface healing takes 2-3 weeks. The graft itself matures over 6-9 months for a lateral sinus lift, and 4-6 months for a crestal approach. If an implant was placed simultaneously, it integrates during the same healing period. A follow-up CBCT scan confirms adequate bone volume and density before any implant loading.
Yes, if there is at least 4-5mm of native bone below the sinus floor to provide initial implant stability. The implant is placed through the bone, and the sinus is lifted around it. If less than 4mm of bone remains, the sinus lift is done first, the graft is allowed to mature, and the implant is placed as a second procedure.
Small perforations (less than 5mm) are repaired with a collagen membrane placed over the tear, and the procedure continues. Larger perforations may require aborting the graft and allowing the membrane to heal for 3-6 months before a second attempt. Dr. Walied Eldomiaty uses piezoelectric instruments specifically to minimize this risk, as they cut bone while leaving the soft membrane intact.
The sinus lift reduces the volume of the maxillary sinus slightly, but the maxillary sinus is much larger than the space occupied by the graft. You will not notice any change in breathing. Temporary congestion in the first 1-2 weeks after surgery is normal and resolves as healing progresses.
Do not blow your nose for 2-3 weeks. Sneeze with your mouth open. Do not use a straw. Avoid flying for 1-2 weeks (cabin pressure changes can stress the membrane). No heavy lifting or strenuous exercise for one week. Do not smoke — smoking significantly increases the risk of graft failure and infection.
We typically use a combination of allograft (processed human bone) and xenograft (processed bovine bone) mixed with PRF from your own blood. The allograft provides osteoinductive proteins while the xenograft maintains space and volume as it resorbs very slowly. In some cases, autogenous bone chips are added to enhance osteogenesis.
Sinus lift procedures performed by experienced surgeons have success rates of 95-98%. Implants placed in sinus-grafted bone have survival rates comparable to implants placed in native bone. The most significant risk factor for failure is smoking, which reduces blood supply and impairs bone graft integration.
Yes. Bilateral sinus lifts are commonly performed in a single surgical session, especially when the patient will need implants on both sides of the upper jaw. This means one recovery period instead of two. The procedure is longer, and IV sedation is recommended for bilateral cases.
In most cases, yes. Chronic sinusitis or allergies do not prevent sinus lift surgery, but active sinus infections must be treated first. If you have a history of sinus surgery or significant sinus pathology, we coordinate with your ENT physician and review your CBCT scan carefully before proceeding.
A lateral window sinus lift typically ranges from $2,000-3,500 per side, depending on the extent of augmentation and the graft materials used. Crestal sinus lifts are less expensive, usually $800-1,500. Insurance may cover a portion if the procedure is medically necessary for implant support. We provide a detailed estimate after your CBCT evaluation.
The upper back jaw area often has insufficient bone height due to the proximity of the maxillary sinus and bone resorption after tooth loss. A sinus lift augments this area with bone graft material to create space for dental implants.
Sinus lifts are performed under local anesthesia with optional sedation. Most patients experience 3–5 days of mild-to-moderate discomfort managed with medication. Swelling and minor nasal drainage are normal for 1–2 weeks.
Traditional (lateral window) sinus lifts require 6–9 months of healing before implant placement. Minimally invasive (crestal) sinus lifts can sometimes allow simultaneous implant placement.
