Implant Failure Complications
Implant Failure Complications is a specialized dental service provided by the board-certified specialists at Aloha Dental Specialty Center in Beaverton, OR. A less invasive sinus augmentation performed through the implant site — often with same-day implant placement.
We know dental care can be stressful. Our team goes out of their way to make every visit comfortable, clear, and unhurried.
Lifting the Sinus From Below — A Simpler Path to Upper Jaw Implants
A crestal sinus lift (also called an internal or osteotome sinus lift) approaches the maxillary sinus from below — through the same osteotomy being prepared for the implant — rather than creating a separate window in the lateral wall. Using osteotomes or hydraulic pressure, the sinus floor is gently pushed upward through the implant preparation site, creating a small tent of space that is filled with bone graft material. The implant is then placed into the same osteotomy, often in the same appointment.
This approach is ideal when the existing bone height beneath the sinus is 5 to 8 millimeters — enough to stabilize an implant but not enough for a full-length fixture without augmentation. By adding 2 to 4 millimeters of bone height through the crestal approach, Dr. Ostovar can place a standard-length implant without the larger surgical intervention of a lateral window sinus lift. The procedure adds only 10 to 15 minutes to the implant placement and typically requires no additional incisions beyond what the implant surgery already involves.
Recovery from a crestal sinus lift is nearly identical to standard implant placement because the surgical site is minimal. There is no lateral window, no large graft to contain, and the sinus membrane is displaced rather than extensively improved. Patients follow the same post-operative instructions as any implant case — soft diet, no nose-blowing for two weeks, and over-the-counter pain management. The bone graft and implant integrate simultaneously over three to four months.

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.

Hydraulic Sinus Elevation: The Physics of Lifting the Membrane From Below
In the crestal approach, the Schneiderian membrane is improved using one of two techniques: osteotome-mediated tapping or hydraulic lift. The osteotome technique uses graduated bone condensers that tap upward through the osteotomy, fracturing the thin sinus floor bone in a controlled greenstick pattern and pushing the membrane upward. The hydraulic technique uses saline pressure injected through the osteotomy to balloon the membrane upward without direct contact. Both techniques limit the elevation to 2 to 4 mm, which restricts the technique to cases needing moderate augmentation. Studies show implant survival rates of 96 to 98 percent for implants placed with crestal sinus lifts — equivalent to implants placed without sinus augmentation.
Why Choose a Specialist?
The crestal sinus lift is a "blind" procedure — the surgeon cannot see the sinus membrane directly. Success depends entirely on tactile feedback, CBCT-informed knowledge of sinus floor thickness, and the ability to detect membrane perforation by feel. Dr. Ostovar's extensive sinus lift experience means he can feel the subtle "give" when the bone fractures and the membrane lifts, and he can detect the loss of hydraulic resistance that signals a tear. These are skills built through repetition, not from a textbook.

From Dr. Ostovar: What I Tell My Implant Patients
“In my experience placing thousands of dental implants, I’ve found that the patients who do best are the ones who understand what they’re getting into. It’s not a painful procedure — most people tell me it was easier than the extraction. But it is a process. You’re looking at 3-6 months from implant placement to final crown, sometimes longer if we need to build bone first.
I won’t sugarcoat it: not every patient is a candidate right away. If you’ve had teeth missing for years, you’ve likely lost bone. That doesn’t mean you can’t get implants — it means we may need a bone graft or sinus lift first. I’d rather take the time to build a solid foundation than rush and risk failure.
The materials matter too. We use Nobel Biocare and Straumann titanium implants — these are the systems with the best long-term research behind them. For the crown, I typically recommend zirconia or e.max porcelain depending on the location in your mouth. Front teeth get a different material consideration than molars.
If you’re comparing costs, a single implant at our Beaverton office runs $3,500-$5,500 including the crown. That’s competitive for the Portland metro area, and we offer CareCredit 0% financing. Most PPO dental insurance plans now cover a portion of implant costs — our team will verify your benefits before we start.”

Frequently Asked Questions
What is the difference between a crestal and lateral sinus lift?
A crestal sinus lift approaches the sinus from below through the implant osteotomy and adds 2 to 4 mm of bone. A lateral sinus lift creates a window in the side wall of the maxilla and can add 6 to 10 mm. The crestal approach is less invasive but limited in how much bone it can add. Dr. Ostovar selects the approach based on how much augmentation your case needs.
Can an implant be placed at the same time as a crestal sinus lift?
Yes, this is the standard protocol. The implant is placed through the same osteotomy used to improve the sinus floor. The existing bone height (5 to 8 mm) provides primary stability for the implant while the graft above it matures. This combined approach saves months compared to a staged lateral lift.
How much bone height do I need for a crestal sinus lift?
At least 5 mm of native bone height beneath the sinus is ideal for the crestal approach. This provides enough bone to stabilize the implant while the crestal lift adds 2 to 4 mm above it. If you have less than 5 mm, a lateral window sinus lift is generally safer and more predictable.
Is a crestal sinus lift less painful than a lateral sinus lift?
Yes, most patients report less post-operative discomfort with the crestal approach because there is no lateral incision, no bone window, and less soft-tissue manipulation. Recovery is similar to a standard implant placement. Over-the-counter ibuprofen is typically sufficient for pain management.
How long does a crestal sinus lift take?
The sinus elevation portion adds about 10 to 15 minutes to the implant placement procedure. Total chair time for a crestal sinus lift with simultaneous implant placement is approximately 45 to 60 minutes — only slightly longer than a standard implant procedure.
What is the success rate of crestal sinus lifts?
Published studies report implant survival rates of 96 to 98 percent when placed with crestal sinus lifts — statistically equivalent to implants placed in sites that did not require sinus augmentation. The technique is well-established with over 20 years of clinical data.
What happens if the sinus membrane tears during a crestal lift?
Because the crestal approach is performed through a small opening, detecting and managing a tear is more challenging than with the lateral approach. If a tear is suspected, Dr. Ostovar may abort the sinus elevation and place a shorter implant or convert to a lateral window approach. Minor perforations often heal without complication.
What graft material is used in crestal sinus lifts?
A small amount of particulate bone graft — typically allograft or xenograft — is placed through the osteotomy into the space created by the improved membrane. Some clinicians use PRF alone for small elevations. The graft serves as a scaffold for new bone formation around the implant apex.
How much does a crestal sinus lift cost?
A crestal sinus lift typically adds $500 to $1,500 to the implant procedure, depending on the graft material used. This is significantly less than a lateral window sinus lift ($2,500 to $5,000) because the surgical technique is less involved and the graft volume is smaller.
Do I still need to avoid blowing my nose after a crestal sinus lift?
Yes. The same sinus precautions apply: no nose-blowing for two weeks, sneeze with your mouth open, avoid straws, and no flying or scuba diving for one to two weeks. These precautions prevent pressure changes that could displace the graft or damage the healing membrane.
Who is a good candidate for a crestal sinus lift?
Patients who need one to three upper posterior implants and have 5 to 8 mm of native bone height beneath the sinus. This covers a large percentage of posterior maxillary implant cases. If you need more than 4 mm of added height or have less than 5 mm of existing bone, the lateral approach is more appropriate.
Can a crestal sinus lift be done on multiple teeth?
Yes, each implant site can receive its own crestal sinus elevation independently. If placing two or three implants in the posterior maxilla, each osteotomy can incorporate a crestal lift. The additional time and cost per site are modest.
Is the crestal sinus lift a newer technique?
The osteotome sinus floor elevation technique was first described by Dr. Robert Summers in 1994. It has 30 years of published clinical data and has been refined with improved instruments and hydraulic techniques. It is an established, evidence-based procedure, not an experimental approach.
How long until the implant is ready for a crown after a crestal sinus lift?
The same timeline as a standard implant — three to four months for osseointegration. The crestal sinus lift heals concurrently with the implant integration. There is no additional waiting period beyond the standard healing phase. Once integration is confirmed, the crown process begins.
What are the advantages of crestal over lateral sinus lifts?
Less invasive surgery, shorter procedure time, less post-operative discomfort, lower cost, faster recovery, and the ability to place the implant simultaneously. The limitation is the amount of bone that can be added (2 to 4 mm versus 6 to 10 mm with a lateral approach). For appropriate cases, crestal is the preferred technique.
